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 a 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 - converters solar energy;
• 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).

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 last 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 even heard about this technology. 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 equipment,

All this makes it impossible to implement solar systems into existing infrastructure. After all, to justify to each resident apartment building the cost of introducing new items is sometimes impossible. 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 – 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.

Alternative energy sources are actively capturing the consumer market. About ten years ago, most people did not imagine the possibility of acquiring such engineering developments, how wind power plant or a solar station. Now it becomes possible. Solar panels for the home: kit cost, installation and maintenance costs - economically profitable solution today.

If we talk about solar panels in technical terms, you need to understand that we are talking about photovoltaic power supply systems (PVS). The main purpose of such devices is to convert the energy of sunlight into electrical energy based on the physical law of the photoelectric effect. About two hundred years the process of improvement has been going on solar installations for electricity generation. Currently, engineering thought has achieved significant results in the development of photovoltaic equipment, especially in terms of efficiency - from 1 to 46% (share of converted solar energy).

Convert sunlight energy into electrical energy

The modern market for solar power supply systems can be considered in sufficient formed, as it allows you to make a choice of goods from a considerable number of offers, from a very large market segment. To answer the most frequently asked question, how much do solar panels cost for a private house, you need to understand the technological and design features FSE. The structuring of the equipment offered by the market assumes three main categories of solar systems, based on their functional, design and technical features.

The first category of FSE includes autonomous systems that are not connected to the main power supply network. Such systems operate in their own network loop to directly power the connected equipment. Maximum efficiency operation is achieved by the presence of a storage device (batteries) in the set, which allows the use of the accumulated electricity in the event of a fall in the intensity of sunlight (i.e. reduced generated power) and in the event of moments when the consumed power exceeds the generated one.

The second category includes open FSE. In their configuration, these systems do not have batteries and are connected to the main power supply network through a special inverter. If the power consumed does not exceed the value generated, the main network is disabled. Otherwise, the FSS is turned off and consumption is made from the main network. Such systems are very reliable, cheaper, but if there is no power supply from the main network, then the solar station does not work.

The third category is represented by combined FSE. They are a combined format of the first and second categories. This allows you to have an additional quality in its functionality - excess generated or accumulated electricity can be transferred to the main network and have commercial value.

Useful advice! For an uninterrupted power supply in cases of simultaneous shutdown of the general network and the impact of adverse weather conditions, it is necessary to have a backup power supply. A small (2-5 kW) electric generator running on gasoline or diesel fuel can be used as such a source.

The price of solar panels for the home: the cost of the kit

It is necessary to solve the issues of saving energy costs by installing solar power plants in the conditions of full information about the prices for the entire set and the upcoming costs for their installation and operation. FAQ, how much does a solar battery for a home cost, does not have a clear answer, since so many factors affect pricing.

The established price of the main element of the PSE (solar battery) is, on average, at a minimum (but also at a minimum in quality) of the order of 50-60 rubles. for the generated 1W of power. Consequently, the price of solar panels for a private house with a capacity of 100 and 200 W will be in the amount of 6000 and 12000 rubles. respectively.

The composition of the station set depends on its category and power. It may include a charge controller, a battery station, an inverter and connecting equipment. When choosing, for example, a set of the first category and a rated power of about 2 kW (2000 W), the price of a set of solar panels for a house will be from 120 thousand rubles. and higher.

And it is necessary to compare all the capital expended with the economic effect obtained from the difference in the cost of 1 kWh centralized network and the value created by the FSE.

The most "fresh" statistics of the solar battery market shows that the ratio of prices per unit of electricity is 8.8 times. This means that electricity generated by a solar station is 8.8 times cheaper than electricity provided through common network taken in equal equivalent.

An important criterion for choosing in the direction of using the FSE is also the factor of the ability to ensure the uninterrupted operation of automation in heating systems, security monitoring and fire warning. The list includes computer home network and groups of electronic control and measuring sensors.

Application and price of solar panels for home

A large selection of solar panels provides an opportunity to use them in a variety of qualities and applications, since if you want to buy solar panels for your home, the price today already allows you to do this for the general population. Knowing their main characteristics, such as the output voltage standard (12, 24V and higher), as well as the parameters of the generated rated power, you can use them locally without purchasing the entire set. On the market average cost solar panels for a private house ranges from 60 rubles. for the generated 1 kW of electrical power.

If you want to use a light bulb in a dark room with a voltage of 12V and a power of 25 W, then it is enough to buy and connect a solar battery of similar parameters to it directly, and this will cost no more than 2000 rubles. and you won’t have to spend electricity on a 60-75 W light bulb in some closet. You can connect a small well pump for daytime watering of any landscape area with a power of 200 W and a power supply of 24V. At a cost of 11,000-12,000 rubles. it is possible during the entire spring-summer period and more than 10 years to have independent system glaze.

The necessary set of solar panels for giving

If we consider the question of the feasibility of using solar systems for suburban area, one should take into account the factors of stability in the supply of electricity to the village, the level of its insolation (the time spent in direct sunlight), the required power of electrification and the risk factor of theft in the empty season from the owners. The best option is a stationary FSE installation of the first category.

Considering the low power consumption of the dacha, it is possible to organize a 100% replacement of the centralized power supply with an autonomous and cheap one. In another case, when the stationary installation of a solar station is not justified by some criteria, a quick assembly moving kit can be used.

Note! Experts in the field of the use of FSE have calculated and found that solar panels are strategically and economically feasible for use in the summer in private homes and country houses area from 50 to 300 m², designed for a family of up to four people.

Using solar energy to generate heat

Along with the use of solar energy for the production of electric current, there are no less common devices for converting sunlight energy into thermal energy. Such installations are called solar collectors and serve as heating elements for heating systems and receiving hot water. Regardless of the installed boilers in heating systems and hot water circuits, their combination with highly efficient solar collectors can save up to 36% of heating and hot water costs.

IN design solar collector from discharge hot commodity is a rectangular panel with dimensions of approximately 1x2 m and with a thickness of up to 100 mm. The main difference between the collectors of these standard sizes is the thermal power flow, i.e. the amount of heat that can be transferred to any heat transfer fluid through the contact surface. In another way, this parameter is called the heat loss coefficient and which has the dimension of W / m² × ° K, i.e. heat transferred across the area to raise the temperature of the receiving fluid. Modern designs solar collectors have indicators (one panel) for thermal power from 1.2 to 5 W/m²×°K.

Prices of solar collectors for home heating

The main element of the system (heating station) is the panel solar collector. Depending on the required power, it can be purchased on the market at a price of 18-20 thousand rubles. per 1 m² of usable area and an average heat loss coefficient of 2.5-2.7 W/m²×°K.

For example, a panel of European quality with dimensions of 1.9x1.8 m (area 3.5 m²) and with a coefficient of 2.7 will cost about 70 thousand rubles.

Taking into account competition analogue Chinese made can be cheaper by 30-55%, and the domestic prototype by 10-25%.

If we talk about the required kit, which includes: a tank, a battery, a pump and automation, then the average market price of such a station will be 160-170 thousand rubles. Set domestic production with similar parameters will cost 100-120 thousand rubles.

Installation on the roof of the house

Useful advice! Sharing solar collectors with solar panels at right choice parameters allows to reduce the cost of thermal energy for hot water production up to 61%.

Manufacturers overview. Solar panels for the home: the cost of a kit and one panel

solar technology as alternative sources energy confidently took a leading position in the market. A large number of manufacturers are actively competing, offering more and more innovations. The leading place in the sales volumes of the TOP-15 countries of solar power plants and their components is occupied by China, with more than 50%.

The most popular brands are Exmork, RENE SOLA, LDK, Helios House, Suntech, JA Solar, etc.

European manufacturers with a market volume of about 25% are represented by such companies as the German AXITEC GmbH, Solarworld and Viessmann Group and the Norwegian Renewable Energy Corporation, etc.

Japan, Korea and Taiwan (15%) are represented by Kyocera, Sharp, Sanyo, Hanwha Solar One and Motech.

Domestic products are represented by such companies as Hevel Solar and TCM. The American manufacturer is First Solar.

Buying solar panels for your home can be relatively inexpensive. If we take a 200 W solar panel as a consumer sample, then the price range will be within:

To see the difference in pricing policy, which mainly depends on the power rating, let's take for example a solar power plant for a 5 kW home, the price of which is Chinese version will be:

• about 300 thousand rubles. (solar battery);
• about 420 thousand rubles. (whole set).

Quality of sales and prospects for the development of solar technologies

The modern market and its sales technologies do not leave the buyer with an unambiguous assessment. Especially high-tech equipment and devices. This also applies to the market for the sale of solar power supply systems. Since the production technologies themselves are very energy-intensive, if you want to purchase solar panels or buy a solar power plant for your home, the price in both cases will call for a detailed analysis not only for technical and technological features, but also for economic justifications.

Alternative electric power industry achieves everything every year large scale. The increased interest in this area is due to two extractable benefits: lower costs in the long term and preservation of the pristine environment. Today, progressive methods of extracting electricity have reached privately owned buildings, we will consider this issue today on the site

To supply private properties with direct electric current, solar panels are installed on buildings. Scientists have made great strides, working for more than 200 years to improve systems for converting light waves into electrical current. Consider the benefits and characteristics various types solar panels, the average market cost of the kit, the features of installation and operation of autonomous power plants in a private house.

The principle of operation of solar panels

The operation of the device is based on the law of the photoelectric effect. Under the action of the sun electromagnetic radiation- visible light - a converter made of silicon or an alternative material emits electrons. Thus, a photovoltaic system installed on the roof of a private house becomes a source of uninterrupted power supply for its residents.

Considering the cost of solar panels for the home, it is right to start with an acquaintance with existing varieties photovoltaic installations. Today, this market is well formed, so that the consumer has the opportunity to choose a system that meets the individual needs of the family.

Which photovoltaic installation kit to buy for a private house

The development of engineering thought has led to the creation of three main categories of photovoltaic systems. Each of them has constructive and technological features, differs in some nuances of functioning.

Solar batteries of category I - autonomous

The main difference between the systems of this group is the lack of connection to a centralized power supply network. The equipment connected to the installation receives direct power. Autonomous systems equipped with rechargeable batteries, which allows you to have uninterrupted power supply during a period of lack of sunlight.

Solar panels II category - open

This equipment is connected to the centralized power supply system through an inverter. The battery is not included. When the level of power consumption becomes higher than the generated power, the photovoltaic system is turned off, transferring the devices to power from the main power grid. In the opposite situation, the central power grid is blocked. This is the most economical and reliable option. However, in the absence of a centralized power supply, the operation of the system is impossible.

Solar batteries category III - combined

A feature of the installation is the supply of excess generated electricity to the main network. Solar panels with this configuration are the most expensive.

Advice! In the event of a simultaneous shutdown of the main power supply channel and a shortage of sunlight, a small power generator should be purchased. This step will protect against unexpected power outages at home.

The cost of a solar power plant for private property

Having decided to switch to an economical mode of supplying electricity at home, it is important to consider the prices not only for the kit, but also for its installation and maintenance. It is rather difficult to name the specific cost of solar panels, since more than one factor influences its formation.

The price of the kit is affected by:

• system category;
• power;
• quality;
• manufacturer.

Find out the approximate cost of the kit autonomous power plant for the home, the calculation will help based on the available data. It is known that to generate 1 W of power, it is required to spend about 60 rubles. It is easy to calculate the cost of purchasing a kit that produces 100-200 watts of power (enough for small house) - 6000-12000 rubles. It is worth considering that this calculation covers the lowest quality photovoltaic equipment.

When choosing a set of solar panels for a private house, it is also important to take into account the guarantee of uninterrupted power supply. This is especially important for maintaining the stable operation of the heating systems installed in the house, external and internal monitoring, fire alarms and computer support.

Price of an incomplete set of photovoltaic system

To understand how feasible it is in a particular case to purchase a set of solar panels for a home, you need to do the following: correlate the cost of a unit of power produced by a centralized power grid with the price of the same amount of power converted from sunlight. Comparison of current prices shows that this ratio is 8-9 times in favor of photovoltaic equipment.

The output voltage of solar panels is -12 V, 24 V or more. The characteristics of the elements of the kit allow them to be used separately, without connecting the entire kit. Recall that to obtain 1 W, you need to spend about 60 rubles on photovoltaic equipment.
To get 1 W from solar energy, you need to spend about 60 rubles

Let's move on to the specifics of local use. For example, if you need a 25 W bulb rated for 12 V to illuminate a small area, you can purchase a solar panel with suitable parameters for this purpose, which will cost about 2000 rubles. A small well pump with parameters of 200 W and 24 V can be connected to a non-volume photovoltaic system. An irrigation system based on it will last more than 10 years and will cost about 12,000 rubles.

A set of solar panels to the country

When planning the use of a photovoltaic system in the country, it is important to consider several nuances:

• stability of centralized electricity supply in the area;
• the risk of theft during the absence in the country;
• required electrification power.

Most often, a set of solar panels of category I, that is, an autonomous type, is installed in the country. Autonomous power supply for a building with low energy consumption is financially profitable. In some cases, a mobile kit is used.

Interesting! According to the data obtained through the analysis, it was found that it is beneficial to use photovoltaic installations for country house with an area up to 300 m².

Solar independent heating system for the house

Not only photovoltaic systems, but also collectors for heating and water heating are built on solar energy. When using a quality installation, you can save more than 30% of the funds spent on these needs.

The solar collector is a 10 cm thick panel with an area of ​​1 × 2 m. Varieties within the indicated dimensions differ in the heat loss coefficient, which reflects the amount of thermal energy transferred to the heat transfer fluid. For one modern panel solar collector, this value is 1.2-5 W/m² × °K.

It is important to understand that when it comes to the price of a solar thermal plant for a home, it usually means purchasing a complete set. It includes a pump, tank, battery and other components. For such a set, on average, you need to pay from 100 to 170 thousand rubles. It should be noted that when buying a system of domestic manufacturers, you can save about 50-60 thousand rubles.

If we consider the cost of a single solar collector panel, then for 1 m² with a heat loss coefficient of 2.7, you will have to pay 18-20,000 rubles. The domestic analogue will cost on average 15% cheaper, the Chinese one - 40%.

Important! The cost of hot water can be reduced by more than half by combining systems of collectors and batteries operating on the radiation of daylight.

The price of one solar panel and a whole set from different manufacturers

Alternative energy, aimed at converting solar radiation into direct current, is moving forward at a rapid pace. The number of companies producing such systems is increasing every year. China is the leader in the production of solar devices for generating electricity and heat.

The average cost of a panel (200 W) / a set (2,000 W) of solar panels from different manufacturers (in rubles):

• China - Helios Haus, Suntech, etc. - 12 000 / 140 000
• Russia - TCM and Hevel Solar - 16 000 / 170 000
• Europe - Viessmann Group, Solarworld and others. - 16 000 / 220 000
• Asia - Motech, Kyocera, Sanyo, etc. - 13 000 / 16 000
• USA - First Solar - 27 000 /38 000

The dependence of the cost of solar panels on the quality of service

Before you decide to buy, you need to ask not only the cost of a set of solar panels and the reliability of the manufacturer, but also the quality of the services provided by the supplier.
