Solar panels for private. Solar independent heating system for the house

Speaking of solar panels, each of us, first of all, means their use somewhere in the country or in our country house. But few people think that batteries that consume solar energy can even be installed on the roof. apartment building, and in this case the solar system will have much more pluses.

This practice is highly developed in many European countries, but the good news is that Russia is not far behind them. Dozens of houses different regions countries are already equipped with solar panels, which have reduced lighting costs by several times. Who is the pioneer? How to organize this system? Answers to this and other questions in the following sections.

What is a solar panel kit suitable for?

There is no need to talk about the complete exclusion of the central power grid from the life of residents of an apartment building. Each apartment has a considerable number of electrical appliances, and the solar system is clearly not suitable for powering them. But street, access lighting, elevators, heating may well be carried out at the expense of solar energy.

In addition to installing solar panels, it will be necessary to provide for the replacement of conventional incandescent lamps. LED lamps consuming much less energy. And the use of motion sensors will allow you to turn on the lighting only if necessary, excluding the operation of lamps throughout the night. Practice shows that such a system can reduce the price per 1 kW by an average of 70-90%.

Organization of a system for an apartment building

The higher the power of the purchased solar system, the higher its price, but on the other hand, the less cost one individual element. A set of solar panels purchased by residents of the whole house will cost much less per person than a system installed in a country house. The SB system has the following advantages:

1. No need for additional space for installation. The solar panel kit is mounted on the roof of the house and on its south-facing side.
2. The energy accumulated during daylight hours can be spent on lighting and the operation of elevators at night.
3. High-rise buildings eliminate one of the main disadvantages of rooftop installation - shading by objects located in the neighborhood. This promotes good lighting. installed panels and, as a result, high performance.
4. The roofs of most houses are flat, which also simplifies the installation of batteries.

It turns out that the benefits of solar panels for an apartment will be much greater than for country house. For example, in Switzerland, a similar system for an apartment building was implemented 20 years ago. The SB set installed on it is used for heating and water heating for household needs. In Russia, similar systems do not have such a massive scale, but they also exist. More details in the next section.

Solar houses in Russian regions

Let's start with the capital. As an experimental site, on which a set of four solar panels was installed, house No. 15, located in Leontievsky Lane, served. Moreover, this idea was implemented already 6 years ago. To date, this is not the only sunny house in Moscow. The administration of the Svyatoshinsky district also distinguished itself, on the initiative of which 18 batteries were installed on the roof of the house at Bulgakov, 19. The generated energy is spent on lighting landings, attics, porches. According to the developer of the solar complex in Leontievsky Lane, their system paid off already in 2 years.

In October of this year, in the Krasnoyarsk Territory, energy saving house, which is heated due to the fact that a set of collectors is installed on the roof of the house, which heats water in boilers in the basement of the building. Similar systems have also been implemented in Kemerovo and the Altai Territory. The residents of Yekaterinburg did not stand aside either. On its own initiative, the partnership of the house at 8, Rodonitovaya, installed a set of collectors, which is planned to be used to heat the apartments. Of course, we are talking about an additional source of heat supply, but this is already a big breakthrough for the Russians.

Nai large quantity houses, lighting in which is implemented using SB, is found in the Caucasus. In the village of Essentukskaya, at least 7 houses have already been disconnected from the central power supply network thanks to the installed solar modules, batteries and LED lamps. This allows apartment owners to save up to 2 thousand rubles a month. And in Novocherkassk in July this year, a house was put into operation, supply hot water in which SB is also provided.

Solar panels on the roof of the Yekaterinburg house:

Nowadays, almost everyone can collect and get their own independent solar power source(scientifically they are called photovoltaic panels).

Expensive equipment over time is compensated by the opportunity to receive free electricity. It is important that solar panels are an environmentally friendly source of energy.

Behind last years prices for photovoltaic panels have fallen dozens of times and they continue to decline, which indicates great prospects for their use.

In its classical form, such a source of electricity will consist of the following parts: directly, a solar battery (DC generator), a battery with a charge control device and an inverter that converts direct current into alternating current.

Solar batteries consist of a set solar cells (photovoltaic converters) that directly convert solar energy into electrical energy. Most solar cells are made from silicon, which is quite high cost. This fact determines the high cost electrical energy obtained by using solar panels.

The most important technical parameter of a solar battery, which has a major impact on the efficiency of the entire installation, is its useful power. It is determined by voltage and output current. These parameters depend on the intensity of sunlight falling on the battery.

Where is it appropriate to put it?

Install solar panels in apartment buildings and connect them to the apartment electrical network is, of course, impractical.

• Firstly, you are unlikely to be allowed to do this by the supervisory authorities for the operation of urban electrical networks.
• Secondly, quite an expensive panel and complex scheme management, as well as the inconvenience installation work in an apartment building will make your innovation in the field of storing and producing electrical energy economically unfeasible.

But in a private house, cottage or country house, especially if they are located more than 1.5 km from centralized power lines, it is very advisable. Procurement and installation of solar panels, as well as minimum costs their maintenance will pay off in 5-10 years. Also, when deciding whether to install solar panels, you need to determine the average intensity of sunlight for your area (solar insolation coefficient). If you live in sunny areas, then the solar battery will work practically all year round, and therefore will pay off faster. For areas and areas with insufficient luminous flux, it may not be advisable to install panels at all, especially if industrial network provides electricity without interruption.

Price

Solar panels as an additional source of electricity for a private house or cottage are becoming Lately very popular. Despite their still relatively high cost ( one panel with a power of 100-200 W will cost $ 100-150), their installation in many cases can be quite justified.

In 2016, solar panels fell in price in rubles by an average of 30%

Calculation of the cost of a solar power plant for a private house

The most universal solution for providing a private house or cottage with electricity is solar-powered power plants (solar power plants). Typically, such a system consists of the following components:

• solar panels (provide the conversion of light into electricity);
• battery charge controller (correct battery charge mode);
• rechargeable batteries (accumulation of electricity during the day and return in the evening and at night);
• inverter (DC voltage conversion to ~220 V, 50 Hz).

To calculate the cost necessary equipment let us consider in more detail the approximate power consumption options with different levels of generated power and connected load.

1. Complete autonomous system with a monthly consumption of 270 kWh/month

For example, take the most common Appliances: boiler, refrigerator, TV and several energy-saving lamps. A simple calculation of the power of these electrical appliances and the average time of their operation from an autonomous network shows approximate result energy consumption during the day - 8-9 kWh with an average daily power of 0.35 - 0.40 kW. The average monthly result will be about 270 kWh.

To achieve these power outputs, the following components must be included in our system:

• 13 solar monocrystalline panels 180 Wt ($200 x 13);
• 13 solar panel mounts ($25 x 13);
• 10 batteries 12 V, 200 Ah ($ 130 x 10);
• inverter 48 or 120 V, 2 kW ($ 300).

Total: $4,500.

To calculate the cost of the components, average market prices were used, which gives a quite adequate idea of ​​the level of financial costs. At the same time, it is important to take into account that if the life of solar panels can be from 20 years or more with only a slight decrease in their efficiency, then the battery life, on average, is about 10 years.

1. Autonomous system with a monthly consumption of 700 kWh / month

This option differs from the previous one in increased energy consumption, which may be necessary for big family or in the case when the comfort of the inhabitants of the house is put in the first place, and only then - energy savings. For an example of calculating the power consumption, let's take the following electrical appliances: a boiler, a refrigerator, 7 energy-saving lamps, 2 TVs, street lighting and a pump. Approximate energy consumption during the day in this case will already be 20-23 kWh with an average daily power of up to 1 kW. With such indicators, the average monthly result will be about 700 kW / h.

An approximate calculation of the cost of components:

• 33 monocrystalline solar panels 180 Wt ($200 x 33 = $6,600);
• 33 solar panel mounts ($25 x 33 = $825);
• 20 batteries 12 V, 200 Ah ($ 130 x 20 = $ 2600);
• inverter 48 or 120 V, 3 kW ($500).

Total: $10,525.

1. Redundant system with a monthly consumption of 150 kWh

This version of the system is designed to operate during short-term power outages from the main power grid, although it can also be used as a seasonal source of electricity, for example, in country house to meet basic needs. As an example, to calculate energy costs, you can take into account the load from the refrigerator, a pair of energy-saving lamps, a TV and a pump.

With average energy costs up to 5 kWh / day, the simplest system is sufficient, which includes the following components:

• 7 monocrystalline solar panels 180 Wt ($200 x 7 = $1,400);
• 7 solar panel mounts ($25 x 7 = $175)
• 2 batteries 12 V, 200 Ah ($ 130 x 2 = $ 260);
• inverter 48 or 120 V, 0.5 kW ($ 100);
• cupboard automatic start reserve ($270).

Total: $2,205.

1. Two 120W modules, 20 amp MPPT controller, 2 x 100 Ah gel batteries, 1300 W inverter with pure sine wave signal.

Provides electricity to a small country house in summer period without electrical heating. The inverter instantly turns on the circuit backup power when the main is turned off. Max Power consumption of 1.3 kilowatts.

About 3700 rubles. Installation is possible with your own hands.

Benefits of Solar Residential Buildings

• The energy of the sun is infinite (at least for the next 5 billion years, give or take),
• provides clean energy,
• without greenhouse gas emissions, and it can save people money on their electricity bills.

But there are factors to consider when deciding whether to solar energy- and the cost is only one of them. In this article, we'll look at six of the most important questions to consider when you're thinking about investing in a solar panel installation. Using photovoltaic power is a very green solution and a potentially beneficial move, but it's not quite as easy as getting your power from a regular grid.

The first factor is one you may not have thought about:

1. Service

Turning your home on solar power requires more care than when using a conventional old power supply. But not much.

Solar panels have no moving parts. They are part of a complete stationary system. So once they're installed, there aren't many reasons why things can go wrong. Pretty much the only thing a homeowner has to do is keep the panels clean. This is an important task, because there is too much snow, dust and bird droppings on panels can reduce the amount of sunlight. The accumulation of dust on the screen can reduce the amount of electricity produced by the system by as much as 7 percent.

This type of maintenance does not need to be done once a week, however. It is enough to water the panels with a hose from one to four times a year. To do this, you do not need to climb onto the roof. The hose with the nozzle from the ground works great. If there is construction in your area, it is necessary to clean the panels more frequently to avoid additional buildup dust buildup.

In addition, check from time to time that all parts are in working order. In addition, it is necessary to replace the batteries, but this is once a decade.

1. Neighborhood

The location of your home has a big impact on your solar energy efficiency. This is an obvious problem: If your electrical output depends on sunlight, things like shadows tall trees and high shadows of buildings will be a problem.

It's still a big problem than some people realize. different types panels react differently to the shadow. While polycrystalline panels can significantly reduce power output, any part of the shading of a monocrystalline panel will stop power generation completely.

Thus, to build a solar powered house, it is necessary to make sure that there is no shadow on the panel over the roof area during sundial per day (usually from 10 am to 2 pm) and preferably during all sunny hours. The more hours the panels are exposed to full sunlight, the more efficient the power generation will be.

Achieving the greatest efficiency may mean pruning or completely removing the trees in your area. If your home is surrounded by tall buildings that block the sun from the roof, this is a big problem.

1. Insolation

Sunlight obviously plays a key role when it comes to solar energy and not all regions are created equal in this respect. It is important to know how much sunlight reaches the ground in the area where your potential solar home is located.

What we're talking about here is called insolation, a measure of how much solar radiation hits the earth in a given area in a given period of time. This is usually measured in kWh/m2/day and it will tell you how much sunlight will be available for your solar panels to turn into electricity. The higher the insolation value in your area, the more electricity each of your panels will be able to generate. high value insolation means you can get more power from smaller panels. The low insolation value means you could end up spending more to achieve the same power output.

So you should build your solar home in the southwest, not the northwest? Not at all. It just means that you will probably need more panels to achieve the same power output.

1. Coverage

Contrary to what most people think, the size of a solar power plant has nothing to do with the size of a house.

Instead, only two parameters should be taken into account:

• insolation, which we have just discussed,
• how much power do you need.

To get a very rough estimate of how big system you need, look at your electricity bill and find out how much kWh you use per day.

The average home uses about 900 kWh per month, or about 30 kWh per day. Multiply this by 0.25. We get 7.5, so we need 7.5kW of the system.

A typical solar panel produces up to 120 watts, or 0.12 kW per day. To provide 7.5-kW, you need about 62 panels. One panel can be approximately 142 by 64 centimeters, so a 62-panel would take up approximately 65 square meters.

You should also take into account insolation and how many hours of peak sunlight you get per day, and also make adjustments if you use batteries with panels. Therefore, it is best to turn to the pros.

1. Expenses

In 1956, solar panels cost about $300 per watt. Only the very rich could afford a 7.5 kW system.

Of course, you can partially provide the house with solar energy. If you want to invest $2,000 in solar panels, you can supplement the electricity from the grid with a 1.5kW solar system. Although in the west they already practice renting solar panels. There are no upfront payments. Homeowners pay a monthly rent to use the panels, and the rental company owns and maintains them.

1. Disposal

The service life of solar panels is 40-50 years, the controller and inverter 15-20 years, batteries, depending on the type and nature of use, 4-10 years.
Although the issue of recycling solar panels remains open, only 30% of all manufacturers take them back for recycling.
Nevertheless, the demand for used solar panels is growing every year. Since the extraction of rare metals is becoming more and more expensive, the recycling of panels will lead to their reuse.

In addition: there is a secondary market for photo and wind power installations, where already used equipment can be further used.

In countries with economies in transition, used solar modules can be used. Thanks to more intense solar radiation, these modules can generate more electricity.

On the feasibility of using solar panels for country house in the absence of a central power supply, it’s not worth talking about. Such systems are completely cost-effective and highly economical when compared to fossil fuel generators. But what about the apartment? How suitable are solar panels for apartment buildings Or individual apartments? What are the features of the installation and operation of such systems, we will try to analyze in this article.

Features of installation and operation of solar power plants in apartment buildings

In recent years, it has become extremely fashionable to build "Eco houses", including multi-storey complexes with low energy consumption, energy-efficient lighting on LED lamps or geothermal heating. Awakened people's interest in solar energy as a renewable and endless source of electrical energy. Solar power plants have become so common in the suburbs of megacities and in the news media that there is probably not a single person left who has not heard about this technology at least out of the corner of his ear. But use new technology in high-rise, multi-apartment complexes sometimes fraught with many restrictions:

• the space available for installing a solar array is generally too small in relation to the energy consumption per square meter building area;
• shading from adjacent buildings;
• high initial cost of equipment,

All this makes it impossible to implement solar systems into existing infrastructure. After all, it is sometimes impossible to justify to each resident of an apartment building the cost of introducing a novelty. Therefore, in practice solar houses» are designed long before they are built, selecting locations and infrastructure that best meets the requirements of energy supply systems. At the design stage, engineers will think through all the nuances, minimizing the future energy costs of residents. Or solar panels are installed in homes for general needs, such as:

• illumination of entrances and nearby territories;
• power supply of the security and communication system;
• uninterrupted power supply of electricians of boiler rooms and other public systems.

Justifying such systems is much easier, and the cost of their initial installation is usually lower and pays off faster, bringing benefits to every tenant.

The third option for the use of photovoltaic cells in apartment buildings is individual systems backup power supply installed by residents of individual apartments for their own needs. As a rule, the problems faced by apartment owners dreaming of solar power plants are of the widest range:

• the impossibility of installing the system on the roof of the building due to the failure of the management company;
• lack of windows and, accordingly, adjacent walls (sometimes balconies) oriented to the south;
• shading from trees and nearby buildings, and as a result, limited space for placing an array of solar panels;
• prohibition of management companies on the installation of extraneous equipment on the facade of the house;
• other restrictions on the installation of other components of the equipment.

But despite a long list of restrictions, resourceful tenants multi-storey buildings nevertheless, they install backup systems that succinctly fit into the design of high-rise high-rise buildings.

Non-standard design of a balcony or a mini-power station in an apartment?

The south-facing balcony and radio engineering education of the owner of this apartment predetermined the future of its residents. Now they are not afraid of temporary blackouts or power outages. And the bills for light will flicker in smaller numbers. Indeed, on the balcony of this apartment, instead of the usual PVC panels, there are solar panels.

Four monocrystalline solar panels fit perfectly into the frame of an ordinary balcony, replacing its non-functional elements. Oriented almost due south, they are not shaded nearby standing houses, and generate almost the maximum possible energy. At the same time, the batteries do not damage overall design building, without being conspicuous and succinctly coexisting with other elements of the house.

In summer, such a system generates 1.0 -1.5 kWh per day and can provide energy for a small refrigerator or energy-saving apartment lighting. In winter, when the insolation drops to a large extent, the system will perform the function of an uninterrupted power supply when the mains electricity is turned off.

Recently, the topic of searching for natural energy sources has become more and more relevant. It's not just about saving environment but also in significant savings. Among the most accessible and effective means, allowing you to get electricity literally from nothing, includes solar panels. Home kit cost, reviews and details of the top 8 budget models- in this material.

Principles of operation and types of solar panels for a private house

First of all, in order not to look like an amateur in the eyes of professional consultants, you need to understand that the correct name for solar panels is “photovoltaic converters”. A person who is at least a little familiar with a school physics course knows that light is converted into electricity through p-n junction. It is on this principle that the operation of solar panels is based.

For your information! The efficiency of a photovoltaic cell is influenced by manufacturing techniques. Manufacturers offer latest materials, able to extract energy even on overcast and cloudy days.

It is necessary to dwell in more detail on the types of solar panels.

Amorphous photovoltaic converters

Made of silicon with a thin film structure. They are considered inefficient, as they produce almost a widow less energy compared to other species. But they have their own advantage - they are very thin elements that can be installed on any roof. In addition, they are more sensitive than other types of batteries and tolerate overheating better. It makes sense to buy such solar panels for a private house in order to obtain not the main, but an additional energy source.

Micromorphic silicon

The material of a new generation of photoelectric converters. They confidently outperform their predecessors in terms of price and efficiency. Such solar drives are not so capricious in terms of orientation relative to the cardinal points and the angle of inclination.

These converters are leaders in sales. They can be called the most successful ratio of quality, efficiency and price. Such converters look like bluish squares. They extract electricity even in high cloud cover and cloudy weather. Their only drawback is their relatively short lifespan. Due to the natural oxidation of the surface, the efficiency will gradually decrease from the fourth year of operation.

Single crystal converters

Very efficient appliances suitable for small roof. They are resistant to adverse weather conditions and oxidation. The black squares of these elements are covered with natural protective film under the influence of air. The exceptional characteristics of these elements are matched by their price. The cost of a set of such solar panels for home and summer cottages starts from 500 thousand rubles.

What is the price of a solar panel kit for a home?

A home power plant on photovoltaic segments consists of a set of devices:

• panels - solar energy converters;
• accumulators - drives;
• inverter and controller.

It is important to correctly calculate solar panels for a private house, they optimal amount and power.

For your information! When calculating the required number of converters, it should be taken into account that storage devices also take part in the energy output. The higher the capacity of these devices, the work more efficiently the entire system.

The controller in the home solar power system is an important device. Many prefer to save money and not buy it, and as a result incur additional costs due to the failure of the batteries. The fact is that with an excess supply of energy to the battery, its service life decreases.

So it turns out that the cost of a home station consists of three parts - panels (from 6,000 rubles), batteries (from 6,500 rubles) and a controller (from 3,500 rubles).

How to assemble a do-it-yourself solar panel home kit in the video below:

Solar panels for the home: kit cost, reviews, specifications

The demand for photovoltaic converters is growing and, accordingly, there is an increasing number of companies offering their services for the supply of home solar power plants. How much does a solar battery cost for a private house and are there kits that have already proven themselves in our climate?

So, the effectiveness of the device will depend on several factors:

• power indicators (average daily, peak, seasonal);
• duration of autonomous functioning;
• intensity solar lighting area at different times.

Let's look at the most popular solar panels for the home, the cost of the kit, customer reviews. For analysis, stations with a “budget” cost were selected:

1. Photovoltaic converters must be installed in places that have the longest possible contact with sunlight. It can be either the side of the roof or the wall.
2. When installing solar panels, you need to remember that in winter time they will have to be cleared of snow daily. It is worth considering right away how to make this process convenient and safe.
3. Converters need to prevent overheating. This must be taken into account during installation.

See the video below for more details on the module installation process:

Summarizing

We reviewed the reviews, the cost of solar panels kits for the home. The conclusions are:

1. Photovoltaic converters are indispensable in the absence of wired electricity or in places where it is supplied intermittently.
2. Solar home power plants will make private house autonomous and independent.
3. Among other things, with the help of an environmentally friendly energy source, you will contribute to the conservation of nature.

For ease of maintenance of the panels, it is preferable to place them on the wall or on special stands in the area.
