Compensation from the state for installation of SES: what amount can be obtain

The popularization and dissemination of alternative energy is not cheap. Specialized equipment for home SES requires considerable financial costs, although it has a short payback period. To increase the availability of solar energy to private households, a number of state programs were create. In addition, local authorities also contribute significantly to the promotion of renewable energy.

The example of Zhytomyr and other regions of our country confirm this.

Real assistance in implementation of the newest programs on energy efficiency in Zhytomyr region

Local authorities of regional importance adopted a resolution, according to which 20 per cent of the cost of purchasing equipment for SES is compensate at the expense of the local budget. In addition, this solution also applies to solar collectors – their cost is compensate at a rate of 15 percent.

Last year, this approach gave the first positive results, so the program was decide to be extend for 2018 as well. Head of the City Administration of Zhytomyr Gundich Igor said that the program of energy efficiency proved itself for a year as one of the most necessary. During the year, it became obvious that such programs are very necessary for the population, therefore in the Zhytomyr region it continues to be realize in the future.

Last year, local authorities also supplemented the standard package of compensation payments for the establishment of solid fuel heating and the replacement of old windows with plastic ones, a new section – compensation payments for RES, including domestic SES. At the initial stage of the program, it was plan to include 35 people. They were to receive from the state bodies of 50,000 hryvnia for the purchase of equipment for solar power plants.

In addition, the expectations were surpass – applications from 50 people were receive. Now such activity is gaining momentum. It is for this reason that the decision was taking to extend the program. Mr. Gundich explains that this increased interest in alternative energy is due to two reasons:

– a chance to save on paying bills for electricity;

– to profit from the sale of electricity by the “green” tariff.

Example of other regions of Ukraine

Some other regions of our country also keep up with the Zhytomyr region in the implementation of programs to stimulate the development of alternative energy.

For example, in the Ternopol region, at the expense of the local budget, 20 percent of the loan amount granted for the purchase of equipment for SES is compensate.

Vinnyts’ka also does not lag behind – here they refund 15 percent of the price of solar equipment from state money. The only condition is that the compensation payment must be up to UAH 25,000 in one hand and the loan registration must take place in Ukrgasbank.

In Lvov, the compensation payment is 10 percent of the loan amount for installation of SES. However, you cannot take more than 25,000.

Khmelnitsky’s authorities compensate at the expense of the budget 10 percent of the finances spent for the construction of SES. The main condition is that one person can get up to 50 000 hryvnia for his household.

In Brody, the local budget provides UAH 100,000 according to the provisions of the “Energy Saving Program”. The size of the compensation payment can reach 20 000 hryvnia per house.

How much compensation can I expect when I install a home SES?

To conduct calculations, take for example SES with a power of 10 kW. The cost of such a station is about 250 000 hryvnia. Residents of Zhytomyr and Ternopol region can count on the amount of 50 000 hryvnia. Residents of Vinnitsa and Lvov regions, Khmelnitsky and Brody cities will be paid UAH 25,000 each.

 

Algorithm for obtaining compensation payments

In order to clearly show the procedure for obtaining compensation, consider it on the example of the Zhytomyr region. Equipment for SES can buy for own or credit funds, respectively, and the procedure for issuing compensation, depending on the type of procurement, can change. If you bought equipment for your money, then you should follow the following procedure:

  1. Make your choice regarding the supplier of solar equipment.
  2. Select all that is necessary to install the SES and take an invoice.
  3. Buy equipment and mount it.
  4. Sign a contract with oblenergo.
  5. The Regional Administration should provide the following documentation:

– invoice;

– a certificate from oblenergo that you are connected to the network;

– Ukrainian passport;

– an identification number.

  1. Compensation must be receive on a personal bank account within 14-21 days.

If you preferred to purchase equipment for SES using credit funds, the following algorithm is for you:

  1. Select the equipment from the supplier and take the delivery note.
  2. To issue a loan in Ukrgazbank.
  3. Buy equipment and perform installation work.
  4. Sign a contract with oblenergo.
  5. The Regional Administration should provide the following documentation:

– invoice;

– a certificate from oblenergo that you are connected to the network;

– Ukrainian passport;

– an identification number.

  1. If the decision of the commission is in your favor, the compensation payment will be credite to the credit account.

Compensation is subject to the following types of equipment:

– solar modules

– Battery controllers

– fastening to the roof of the house

– inverters

– cables

– connectors

– electric boards

– accounting equipment

– equipment for protection

– switching devices.

The main thing is to find a reliable supplier

Techno center “Energy of Nature” is an official supplier of quality equipment for SES with different capacities. The company not only performs settlement work and performs the selection of equipment individually, sells and installs – the Techno center issues all the necessary documentation so that the client can receive a compensation payment from the state.

Hendershot generator – operates without fuel

The Hendershot generator, also called the free energy generator, was introduce in the city of Toronto in 1981. Its creator is the American physicist-inventor Leicester J. Hendershot. The presentation by the inventor’s follower at the Congress on the energy of the gravitational field included explanatory material concerning the fact that the device is able to function using the Earth’s magnetic field. In addition, the speaker noted that the operation of the device depends on its placement relative to space and pole orientation.

The first information about the device is mention in the pages of Hendershot’s work for 1927-1930. In his work, he not only provided the circuits and described the principles of the device, but also told that he himself was able to assemble a generator of power of about 300 watts.

During development, several models of the generator were design, but until recently, the invention did not find its application.

To the indisputable advantages of the generator Hendershot can be attribute, in the first place, the lack of the need for fuel. Accordingly, the device does not have any dependencies on the fuel resource.

It should also be note that the device in no way has a negative impact on the environment and works without emitting a single noise. Among the advantages of the generator, you can undoubtedly highlight that it does not need any maintenance and saves considerable finances.

The original model of the generator was a pair of coils having inside the condenser. In addition, the package included a pair of transformers (parts from the old radio) and a magnet. It was important to adjust the coils in such a way that they stayed in resonance. Such an assembly variant could only be functional if it was oriented from the north to the south.

As a result, a device was obtained that could generate electricity. Electricity was enough to operate a small-sized engine. Actually, the inventor himself used it there. His invention Hendershot built into a toy airplane, which his son loved. The airplane thanks to the device could go up in the air and even fly for a while.

The generator circuit is show below:

There is another version of the generator:

The Hendershot generator, like any other device, has its drawbacks: the exact scheme of the device is not yet fully open, not everyone will be able to create a working structure.

Report on Alternative Energy 2018: Mass Changes, Opportunities and Facts

In 2017, 70 per cent of the net increase in mass production capacity was brought to the share of the recoverable energy, but CO2 emissions directly from the energy sector increased 1.4 per cent in the past year, after only 3 years of steady decline. The increase in carbon emissions was triggered by a steady increase in the economy in the world-wide range (3.7%), the lowest price of old fuel and the most inadequate efforts to increase energy efficiency.

In this city, the World Report on RES (GSR) shows 2 realities: one in which a revolution in the energy sector leads to rapid changes in recoverable energy keys, and another, in which a single transformation does not progress at all with the urgency called for. Although the impetus in the energy sector is favorable, someone directly does not in any way guarantee a reduction in emissions as requested by the Paris air-conditioning agreement, or a desire for a stable formation mission. The sections of heating, cooling and motor transport, in part of which are brought about 80% in the mass cumulative final demand for energy, lag behind.

But the message is not so bad. The unified power of producing industries achieved the maximum annual growth already after that, as well as on a mass scale there were added 178 gigawatts. The newest clear photoelectric generating ability began more than the presence of a combination of coal, natural gas and nuclear energy.

And despite the fact that almost 75% of the mass investments in the renewable list of energy and fuel sources were brought to the Middle Kingdom, Europe and the United Sources, in 2017 substantial investments began to operate in the bazaars of developing countries. The presence of measurement in a piece of continuous internal provisions Marshall Islands, Language, Island Islands, Country-Capital and numerous other emerging states will be invested in a renewable list of energy sources in fact (or even more) than formed and emerging states. These positive actions should be increased with a view to a global energy transition.

The corporate resource of renewable energy also increases. Initially, numerous firms evaluated the approval of recoverable energy keys in the main way as well as a document of collective public responsibility. But a significant reduction in expenses in the restored list of energy sources, and in addition, the formation of bazaar and socio-political circumstances have led to this, that RES is considered competitive in accordance with the price and tempting keys of the energy of the female according to itself. As the report shows, the collective list of sources of renewable energy has come from outside the borders of the United States and Europe and now reside in such states, as well as Burkina Faso, the Country, the Celestial Empire, the Country of the Pyramids, the Country, the Country of India, the Land of the Rising Sun, Country, Country and Thailand.

A precise document is needed to display a large number of incidents occurring on a small scale and in sectors of final application. Numerous efforts, dispersed decrees, novelties, start-ups, off-grid additions, clear thermal and other types of work are not noticeable in the presence of the concept of reporting on a mass scale, however, they record a significant investment in collectives. The given researches give abilities with the purpose of expansion and the subsequent transition in the power concept. Obtaining information and observing the development of small-scale conclusions, and in addition, the use of renewable energy keys in key sectors, such as motor transport and agrarian production, must be the newest value.

Based on information and trying to show all, without exception, the most difficult kind in the sector of renewable energy keys, REN21 founded the “Development of a World Renewable Energy Transition: Key Factors of the World Report on the Stay of Renewable Energy REN21 2018 in Opportunity.”

As well as its ancestor in 2017, in this act unlimited orientations and actions of 2018 are presented, with this in order that the leading apparatuses and other societies have the opportunity to most simply realize the role of past incidents in the field of renewable energy keys. Interest is paid to the uneven distribution of recoverable energy keys, as well as in sectoral, and thus in regional degrees. The Act expands the World Report on the Stay of the Renewable Energy Keys of 2018.

SES for a private household is a powerful push for renewable energy in Ukraine

The legislative base of our country is constantly undergoing changes, which now have touched on renewable energy. These amendments regulate the emergence of new ways of making a profit in solar energy, and small solar power generating units (called SEU) can directly help in this. Such kind of generating devices is ideally suited for installation on the territory of private households.

According to the studies conducted by the International Energy Agency, over the past 10 years the capacity of the wind farm has increased six-fold, and the SES – in 33. Such indicators indicate the investment attractiveness of solar energy among other alternative energy sectors. Experts also note that the number of financial investments in renewable energy for the above-mentioned period has increased five-fold. Specifically, solar energy has attracted 10 times more investments over the past ten years – from 2005 to 2015; it has been possible to increase investments from 16 billion dollars to 161 billion. It is also worth noting that solar energy at this stage is about 56 percent in the total amount of investments aimed at introducing new developments and improving existing renewable energy projects as a whole.

Since the spring of 2009, a new method for stimulating the development of alternative energy at the level of legislation-a “green” tariff-has come to our country. It is a duty of the state level, guaranteeing the purchase of energy from alternative sources from those who generate it. It should pay attention to the existence of certain benefits in taxation on the generation of this type of electricity. The current year brought in this area a number of changes.

What are the distinctive features of the “green” tariff in our country?

For several years, experts noted that the “green” tariff in Ukraine is the largest by world standards. This procedure was accompany by well-founded criticism, because the increased “green” tariff did not show a stimulating effect on the generation of energy from the sun through small installations, but only promoted large-scale production.

In 2014, amendments to the Tax Code have canceled some of the tax privilege category, replaced by taxes on income and land. In addition, on 16 July 2015, a new procedure was adopt to determine the amount of the “green” tariff. From this moment to receive profit from the sale of “clean” energy can and private house holdings. It is important to note that the privileges for generating energy from renewable energy sources under the new rules are applicable to wind installations with a capacity of less than 30 kilowatts.

The updated procedure was fix at the legislative level through normative documents in the energy sector. It should also be note that the tariff for operating SES has not changed.

Through the adoption of new legislative documents, it was possible to fix the amount of the “green” tariff until 2030 inclusive (the tariff was adopt and fix in euros). In addition, now the responsibility of NKREC is to recalculate the tariff at the hryvnia rate of the National Bank of Ukraine every three months. The payment according to the “green” tariff is cover by all the energy generated from renewable sources. The only exception is that part of the electricity that the household used to meet its energy needs.

The amendments of 16.07.15 also include the appearance of a “green” tariff for energy extracted from geothermal sources. In addition, the Law established an increase in the tariff for those industries that use biomass or biogas to generate electricity.

In November 2016 another amendment was made. Thanks to her now, the heat pump (hereinafter referred to as “TH”) refers to devices operating with RES. Although TNs consume energy, it is possible to use them as part of an electrical installation of a combined type. That is, use it as a power storage device in circumstances where its quantity in the SEA framework is excessive. TN thus helps to pass the winter maximum.

Such legislative amendments entailed serious adjustments in the situation on the market of alternative energy. There was a previously absent niche for the active work of entrepreneurs of different scales. Thanks to the adopted Laws, the purchase of electricity from small and private producers became mandatory.

Additional levers for stimulating the development of renewable energy:

  1. Article 197.16 NKU states that the import of materials, equipment and components for the generation of electricity from renewable sources is without VAT.
  2. The Customs Code (Article 282) regulates the exemption of this category of import from duties (import and export).
  3. Article 213.2.8. The NKU determines the exemption from the excise tax for the sale of energy, which was produced through qualified (or renewable energy sources). It should be note that at the state level special payments (5 and 10 percent) have been fix, which producers who use components of Ukraine’s production (correspondingly 30 or 50 percent of the components) are entitled to receive.

Such innovations are valid for power plants commissioned from July 1, 2015 to December 31, 2024. Generation of electricity from REE does not require a license. Solar power is becoming increasingly attractive for investing with each new law or amendment to it.

Which CEUs are best for small business or private energy production?

Small network solar power generating plants

This kind of CEU generates energy and transmits to the general network. A certain amount of electricity goes to meet the needs of the household, and those that remain in surplus, enter the network. If weather conditions do not allow solar panels to generate energy, then homeowners get it from the network. Special counters fix the quantity of realized and consumed electricity. Purchase of electricity for the needs of the house is carry out in accordance with the general tariffs, and the sale – according to the “green”. It should be note that the use of small CEUs is the simplest version of power supply.

Network solar power generating units with back-up power

One of the obvious drawbacks of CEU, connected directly to the general network, is the fact that in an emergency the probability of getting electricity is zero. The fault of this may be the violation of the integrity of the transmission line, weather conditions, etc. CEUs having back-up power, in this case they can survive without any problems, because they have a battery.

The cost of such CEU will be higher due to the need to install an inverter and a set of batteries. Unlike the first option, this CEU, in addition to meeting the needs of the household, is also able to accumulate part of its electricity in an emergency in parallel.

Autonomous solar power generating plants

There are situations when the general electricity grid is unavailable for some technical reasons. There are also frequent cases when the power grid is simply not able to withstand some power, so it is strictly limited. Often, such a development of events is prepare by structures located in the forest belt or remote locations. It is for these cases that an autonomous SEU will be the optimal choice. In this version, the installation will only work to meet personal energy needs. Stand-alone CEU assumes a sufficiently large capacity of rechargeable batteries.

This is necessary in order to avoid crashes during peak periods (for example, in winter). The autonomous CEU is deprive of the opportunity to realize excess energy. However, because of this, its economic feasibility is not reduce in any way. Ensuring energy requirements of the structure at the expense of its own generation pays off quite well, because in the end it is more profitable than buying energy from the state. In addition, there are no significant costs for joining the general grid.

Stand-alone solar power generating units with backup power

When there is an option to connect to the grid, it should not offset. With an available spare power supply, the CEU will require a simplified version of the battery that will bring the project tangible savings. An additional advantage is the ability to sell energy to the network when it is more than necessary (most often in the summer).

If the connection scheme is balance and well thought out, then an autonomous ECU, which has a backup power, can cover the consumption of electricity consumed from the grid in the winter due to the surplus in summer.

Solar power generating units of the combined type

This type of generation involves the use of CEU in conjunction with other devices for generating electricity from alternative sources. This eliminates the main disadvantage of solar equipment – the lack of continuous generation. Often, as an auxiliary generator, wind installations are used. The wind is in the “antiphase” with the energy of the sun, because the electricity from wind equipment can be produce both at night and in wintertime. The overall network in this interaction plays the role of a spare power supply. In addition to the implementation of surplus energy, the grid can provide electricity when there is an urgent need.

There are also combined CEUs with a stand-alone standby generator, which usually has a diesel drive. This configuration makes it possible to eliminate crashes in the power supply even if the network fails.

New business

The “energy independence” of SEU due to the “green” tariff does not end their benefits. At this stage, they may well become a separate type of business, both small and medium. Amendments in the legislative framework concerning solar power plants with a capacity of up to 30 kilowatts and the very “green” tariff, allow this area of ​​entrepreneurship to develop actively under existing conditions.

It should also be noted that the increase in generation by 2020 in 2,7 times (relative to the 2014 figures) is planned to be implemented with the help of small SEUs up to 30 kilowatts, which are installed in private households.

The Government of Ukraine plans to adopt a bill that will significantly suppress the progress of energy independence

The Government of Ukraine plans to adopt a bill that will significantly suppress the progress of energy independence

The Government has proposed a strategic plan for 2030 that is ineffective. In addition, if the strategy is approved, then it threatens to significantly reduce investment in the field of alternative energy and calls into question the prospect of economic development of the country as a whole. The Ukrainian Climate Network is actively operating in our country, and the members of the organization have brought this issue to the community review. The representatives of the UKM are very worried about the fact that a disastrous draft law may significantly increase the dependence of our country on the import of fossil fuel resources.

The “Strategy of Environmental State Policies”, developed until 2030 inclusive, was proposed by the Government of Ukraine in April. The bill envisages a permission to increase the emission of harmful CO2 twice compared with the level in 2015. This, above all, will mean that the dependence on imported fossil fuels, which is currently imported into large volumes to Ukraine, should increase in times.

Organizations included in the composition of the UCM are embarrassed by the Government’s permission to consider a strategic draft law that totally ignores the issue of increasing energy efficiency and implementation of RES. Representatives of the organizations also pointed to the fact that at present, the policy of the state should be aimed at the active reduction of fossil fuels in energy, and not on its popularization. It is important to attract foreign financing and improve the environmental status, and if strategy is adopted, all efforts on these aspects may be overtaken.

Also experts of the Ukrainian Climate Network pay attention to the fact that “Strategy” does not have any agreement with already existing ecological documents of strategic importance. It should be noted that documents of international importance, in which Ukraine has undertaken a number of commitments, “the Strategy of Environmental State Policies” in general contradicts.

Government officials have already approved the Energy Strategy of Ukraine, which provides for reducing harmful emissions to atmosphere up to 15 percent compared to 2010. This document has been developed until 2030 inclusive. At the same time, the Ministry of Nature of Ukraine is initiating approval of a strategic plan that will regulate the possibility of an increase in the share of greenhouse gases in 2030 by almost 60 percent (as compared to 1990).

This strategy will make it possible to increase the volumes of CO2, instead of stabilizing its level and gradually reducing it. Experts note that the increase in the share of greenhouse gases in the proposed strategy (from 40 percent to 60 compared with 1990) has a fundamental contradiction with the “Low Carbon Strategy”.

Environmentalists say that Ukraine needs to start formulating the goal and the main principles of the political path towards the climate and the environment as a whole and, after that, to coordinate or make adjustments to the strategic documentation in the energy sector, environmental protection, energy efficiency, etc.

The environmental policy strategy was approved by the Cabinet of Ministers at the end of April of this year and submitted for consideration to the Government. The representatives of the UKM state that the process of harmonizing this issue with the public was formal and did not reflect the real community attitude to the strategy.

It is important to note that, two years later, our country should provide testimony to the United Nations in contributing to global efforts to reduce CO2 emissions. This procedure is specified in the Paris Climate Agreements.

Home-made energy accumulator from the Ukrainian manufacturer will soon be available on the market

While representatives of the company Tesla are working on the launch of a production complex for the purpose of serial production of its powerful batteries, the market filled other firms that are fairly serious competition to each other. Daimler, BMW and Nissan have already started manufacturing home-made batteries. Ukrainian manufacturers are also not lagging behind in this race – they presented a system called Serenis to the general public.

The energy-saving system was introduced in 2015. At the moment, manufacturers reported that they already received all the necessary certificates and permits. Sales of the system in the European market will start in 2019.

The ultrasonic recorder from the Ukrainian manufacturer is a high-tech device; the term for which (which means the beginning of the development and release of the finished equipment) was only three months. In addition to the record-breaking period, the Serenis ESS system has plenty of advantages that allow it to compete with similar devices on the world stage.

The system is not just an accumulator – it is a “smart” device, which allows not only to accumulate but also to convert energy. The system consists of:

– high-tech controllers;

– a system that allows monitoring the state of the Internet and managing power flows;

– Li-ion battery;

– hybrid inverter.

The price of Serenis ESS with the capacity of 3 kilowatts varies within 4000-6000 euros. The cost is directly dependent on the system configuration.

Creators of the system say that their device can be connected not only to solar panels, but also to the equipment generating electricity with the help of a wind. The Serenis system can be charged at night when the electricity tariff is significantly lower. The manufacturer also notes the possibility of selling electricity surplus at the “green” tariff to the general network. The size of the energy accumulator is small, which allows you to significantly expand the list of places to install. Weight of the device is only 30 kg.

Representatives of the company-manufacturer of the system reported that during the presentation of their development, they hoped to receive orders for a maximum of 100 kW (30 Serenis ESS at 3 kilowatts). As a result, orders for the first few days amount about 1 megawatts.

The manufacturer also notes that the company’s registration address is Nyiregyhaza (Hungary). It is located in hundreds of kilometers from Uzhhorod. Despite the fact that engineers worked in Ukraine and the development itself is denominated as Ukrainian, the plant for serial production of systems was located in Hungary, in order to avoid the difficulties of selling them to European countries.

The plant itself is located not far from Nyiregyhaza and is currently in the final stages of construction. The production line is configurable only by experts from Ukraine. After commissioning the plant will be able to produce about 130 systems per month.

A powerful turbine will have a big impact on the sphere of energy production

The number of wind turbines is growing from year to year, but the new development of GE Renewable Energy significantly exceeds its competitors, as it will reduce costs, increase profits and efficiency.

The company will spend $ 400 million on a powerful turbine project that will significantly reduce the cost of obtaining wind power. The diameter of the GE 12 MW turbine will exceed 200 m, and the size of its blades exceeds 100 m. The power factor is also striking – 63%.

The use of a turbine, such as Haliade-X, will allow developers to build units with fewer auxiliary turbines, use fewer cables, reduce construction, maintenance and other costs, and enable faster return on investment.

The company estimates that in 2019 it will have a mock-up for the demonstration, and by 2021 the Haliade-X turbine will be supplied to the US and other countries.

The use of equipment with a capacity of 12 MW will also make wind turbines larger in terms of generating capacities than existing ones, which will require a new approach to financing and their deactivation.

Despite the fact that the wind generator Haliade-X will be well suited for a small wind, its power will allow producing more energy than analogues in similar conditions, increasing profitability and significantly reducing the cost of energy.

The 12 MW turbine will be able to generate more than 60 GW per year, which is 44% more than the annual volume of energy production of the most powerful devices on the market today and twice as much as the GE-Haliade marine turbine of 150-6 MW. The Haliade-X 12 MW will be able to generate enough power to supply 16,000 European homes in the traditional windy weather for the North Sea.

Haliade-X not only set a benchmark for wind turbines, but also the turbine will significantly increase profits for the company’s customers.

The maintenance and repair costs will also be lower due to “simplified technological and intellectual components”.

The new turbine not only helps developers reduce capital costs: with fewer turbines and foundations for installation, in addition to reducing cycle time and simplified operation, Haliade-X 12 MW will also be able to generate significant cost savings for the project over the life of the “windmill “.

Under the terms of the five-year research and development program, the company will test the next-generation technology for Haliade-X, and the turbine will pass test and demonstration programs at the facility that will accurately reflect the actual operating conditions.

Research activities will include cooling technologies, converters, and conditions for loading mechanical and electrical components, testing the network and checking the design.

Cooperation will help improve technology, which will also help develop a number of supplies to the UK and expand access to demonstration opportunities for innovative small businesses.

John Lavelle, President and CEO of the company, said about the decision to test a new turbine in the UK: “This is an extremely important agreement, as it gives us the opportunity to soon prove the effectiveness of Haliade-X, demonstrating its performance under extreme conditions. Catapult engineers will ensure the independent performance, functionality and endurance of each part in particular and the system in general, including the generator and converter, recreating extreme conditions in a controlled environment. The test bench will improve the understanding of the characteristics of the turbine, identify the problems of production and design in a relatively short period compared to field tests. Ultimately, this will shorten the time to market, increase reliability and reduce associated costs and risks”.

Nissan and Tesla offer the best solution for the complete transfer of houses to solar energy

Representatives of Nissan reported that at the moment the sale of their latest development called Nissan EnergySolar started. This system, called still “all-in-one”, consists of solar panels, energy storage xStorage and control systems. The development of Nissan is able to fully provide the household with “green” energy. The implementation of energy supply systems began with the UK.

According to the calculations of the company’s specialists, the installation of such a system in a private house will make it more energy-independent from a centralized network and help save about 66 percent on electricity payments. In addition, this home installation is designed to recharge the company’s electric cars, including the Nissan Leaf.

Residents of the UK will have the opportunity to make a choice regarding the configuration of the installation. They can choose only the solar panels of the company, only the energy storage (where xStorage can be preferred, which has already been used – it will be much cheaper) or install an integrate system.

If the customer installs a complete system, then Nissan EnergySolar will accumulate electricity produced by solar modules during the daytime for later use in the afternoon. In addition, the system has the ability to replenish energy reserves at night, when electricity has a low tariff.

The price of a full-fledged system at the beginning of sales is 10,300 dollars. In addition, it is possible to purchase separately solar panels from Nissan for $ 5,200 or xStorage for $ 8,700.

Despite the fact that already about 880 000 British have solar panels, experts predict this system a good chance and high sales.

The company Tesla also does not lag behind in this matter. Ilon Mask already had a system consisting of a solar cover for the roof and power storage Powerwall, released in an updated version with a double energy density.

Solar tile Tesla is a structured tile made of glass, in which a solar cell is built. The company’s offer includes 4 different types of solar roofs. Also, a household energy store Powerwall of the second generation was introduced. In the new version of the battery, the energy capacity is 14 kilowatt-hours, unlike the previous one, which has only 6.4 kilowatt-hours. Indicators of the nominal power of the second generation drive are equal to 5 kilowatts, and the maximum capacity is 7 kilowatts.

Representatives of the company Tesla said that they provide a warranty for Powerwall 2 for ten years, without limiting the cycles of recharging. Drives can be installed both inside the building (there is a variant of wall and floor mounting), and outside.

The price of energy storage from Tesla is $ 5,500, while the first version cost $ 3,500. The cost of the solar roof has not yet been specified, but, according to the developers, such an acquisition would be beneficial for the owners of households, when compared with traditional roof equipment by solar panels.

What to do if the solar panel is out of order: a practical guide

It happens that the solar battery goes out of order and does not give out the voltage declared by the manufacturer. Most often, this is due to the Schottky by-pass diode that burned inside it. To solve this problem, you must perform the following actions:

– Measure the voltage of the solar battery. Even at this stage, we can make an assumption, how many diodes went out of order. Most often, three diode barriers are install in the panels, each of which is responsible for a certain number of photocells and serves as the main component for preventing the shadow effect.

In the event of failure of one of the diodes, the total voltage will decrease by one third, and if two – by two thirds, respectively. With the combustion of all diodes, the voltage of the solar panel can be only a couple of volts, and this despite the fact that when testing it for a short-circuit current, the amperage will remain within normal limits;

– Open the junction box of the solar panel and find the installed diodes;

– Take the tester and call each diode;

– Identify which of the diodes breaks. The burnt diode can be determined visually – its “feet” will be much darker in color than the whole and have a matte shade. It can also be easily determined by temperature – a burnt diode will have a temperature much higher than an unburned diode (it can even be burned);

– Remove the burnt diode. Usually diodes are simply press by clamping contacts, which must be move away with a small screwdriver and alternately pull out the “antennae” of the diode;

– Mount a new diode with the same characteristics. For example, if a diode is write 20SQ045 – this means that this Schottky diode, and has the following parameters: 20 amperes and 45 volts.

The installation is carry out in the reverse order: a small screwdriver removes the terminal blocks and the contacts of the Schottky diode are alternately insert, if necessary, it is pressed slightly;

– Close the junction box and measure the voltage of the solar panel. If everything is do correctly, the voltage of the panel will be within the limits specified in the technical passport.

In emergency cases, for example, when there is no way to replace a broken diode, you can simply dismantle it and then the solar panel will again give out normal voltage. In this case, it can lead to a rapid overheating of the photocells. It will not be protect from the shadow effect.

Energy supply at home even in the absence of solar panels – startup from the UK

European countries are rapidly moving to distributed energy, which replaced the traditional centralized. Such a transition can significantly save money directly to the consumer, while reducing the profits of the usual energy suppliers.

In the UK, a new start-up called OVO Energy is gaining momentum. Its creator, Stephen Fitzpatrick, predicts a fairly bright future for the energy sector. Mr. Fitzpatrick noted that in the future the consumer will have the opportunity to buy electricity to power his home at a time when the demand for it will be low and the cost, respectively, too. During peak loads on the grid, the average consumer will be able to sell electricity at a high tariff and get an income.

Also in the presentation of a bright future, the developer of the startup notes the ability of electric cars not only to be quickly charged, but also to save energy as a battery. Smart software will allow you to regulate all processes and adapt to customer requests and weather whims.

Three years ago, Tesla Company under the leadership of Ilon Mask presented to the general public a lithium-ion energy storage device called Tesla Powerwall. It was designed specifically to accumulate the energy of the sun. Then the invention of the Mask made a splash, but now Stephen Fitzpatrick is sure that his startup will be able to easily master such a task.

The company of the Irish developer has created a new energy carrier Home Energy Storage, which is designed to save the energy of a certain house. Stephen Fitzpatrick believes that the transition from a centralized power supply to a distributed power generation creates the need to have a similar battery for each house.

The difference between the start-up of Stephen Fitzpatrick and the invention of Tesla is that OVO Energy assumes the accumulation of energy even if the household is not equipped with solar panels. The accumulator accumulates electricity from the common network in the daytime, when the demand for it is low (and the cost too). The stored energy can be used in the evening, when its cost rises at times. In addition, surplus can be sold to the general network, but at an “evening” price.

It is beneficial to buy and sell electricity allows special software called VCharge. The software analyzes the local network regarding the availability of offers at a particular time, analyzes the demand and cost of energy. In addition, the smart system VCharge is able to predict the demand for electricity, based on data on weather conditions. The program independently decides on the time of purchase of electricity and its further use.

Stephen Fitzpatrick notes that in two decades the energy market will have a greater dependence on literate software than on electricity.

In addition to the home energy carrier, OVO Energy, together with Nissan, developed a bi-directional power plant to charge electric cars. The company’s management reports that there are no similar devices in the world.

The new technology will allow owners of Nissan Leaf, in addition to charging their electric cars, also sell electricity during the peak load on the network. According to preliminary calculations, this technology will allow motorists to save about $ 354 per year.
