Solar panels for home: the cost of the kit and what you need to know before buying

Providing a residential building with electricity is an important prerogative of every owner. Along with the more familiar connection to the central system, new options began to emerge. Recently, solar panels have even been installed for the home. The cost of the kit is somewhat high, but such systems fully justify themselves in operation.

Function and types of converters

The generation of electric current is made possible by the effect of solar radiation on the surface of the silicon wafers. When hit by direct rays, electrons are displaced from their own orbits, creating a directed motion of charged particles.Before you buy solar panels for a private house, you need to familiarize yourself with the basic types of converters.

Monocrystalline panels

A characteristic feature of such products is the one-sided orientation of the cells that are sensitive to light. Thanks to this, it is possible to significantly increase the efficiency, but in this case, the susceptibility to sunlight in cloudy weather decreases. In this regard, the devices are recommended to be used in the southern regions, where there are not many cloudy days.

Option using monocrystalline panels

Polycrystalline plates

Due to the multidirectionality of the crystalline silicon cells, the efficiency of the elements is somewhat reduced, but the efficiency of operation in cloudy weather increases. The panels have a square shape and a heterogeneous structure, which is explained by the presence of dissimilar crystals.

This is what polycrystalline batteries look like

The main advantage of solar panels is their high energy efficiency in cloudy weather when the light is diffused.

Amorphous batteries

Such products have a very thin silicon layer. Its deposition on the surface is carried out in a vacuum. Plastic, metal or glass foil is used as a base. Although the efficiency of the panels is relatively low, the performance in cloudy weather and the level of light absorption are adequate.

The appearance of amorphous panels is demonstrated

A significant drawback of thin-film wafers is the relatively fast burnout of the silicon coating.

Combined analogues

Separately, it is worth dwelling on hybrid solar panels for the home, reviews of which users leave mostly positive. With this option, amorphous silicon is combined directly with microcrystals. In contrast to the same polycrystalline analogs, the efficiency of hybrid systems in scattered light is higher.

Solar panels for home: kit cost and specifications

Since the price of solar battery kits for the home can vary depending on the initial parameters, it is proposed to consider several systems at once, suitable for certain operating conditions. The correct selection of power and other characteristics will allow you to do without unnecessary costs.

The system consists of the following elements

Usually the kit includes:

• solar panels;
• accumulators;
• inverter;
• charge controller.

Note! All system elements have a different service life. The plates themselves can last up to 50 years on average, an inverter with a controller up to 20 years, and batteries no more than 10 years.

Power of 1000 W is usually enough for household appliances

The cost of solar panels for home: prices from reliable manufacturers

Popular enough products HiminSolar... The manufacturer produces reliable solar panels for the home. The cost of the kit for a company with a high standard of quality characteristics is quite acceptable. The panels are able to function in a wide temperature range, without losing performance in rainy weather too much.

HiminSolar Products Installed

Rated power, kW	Energy reserve, kWh	Peak power consumption, kW	Average productivity per month, kWh	Price in rubles
1	3,3	1,5	120	202000
2	5	3	240	398000
2,4	10	5	320	438000
3,6	10	5	430	739000
5,4	10	5	650	900000

Useful advice! When purchasing solar panels for country houses, you can choose systems with a lower power, since the energy costs in such buildings are not very high.

The panels are installed on the second floor wall

Another reliable manufacturer - SunShines... The company has been successfully operating in the Russian market since 2010. It also produces ready-made kits in different price categories so that the consumer can choose the best option for specific conditions.

System power, W	Energy reserve, kWh	Energy efficiency, kWh / day	Peak power, W	Price in rubles

Discharge characteristics of the DeltaGX battery

Helpful information! The Delta GX series batteries are manufactured using GEL technology. The electrolyte is sulfuric acid, thickened in the form of a gel, which ensures temperature stability.

Installation work

In order to save money, some consumers install solar panels for their homes with their own hands.This process involves fixing the panels in a suitable place and connecting the components in series.

Panel layouts

The plates themselves can be mounted in several places:

• Installation on the roof of a house involves the creation of a support structure from profiles.
• Wall mounting is not done very often, but it is acceptable. In this case, a special frame system is arranged for holding.
• Attaching to a separate support such as a bar is a suitable option if the roof of the house is shaded or has low load-bearing capacity.

Elements are installed directly under the window

Helpful information! In some cases, solar panels are mounted on balconies if they are not shaded by trees, neighboring houses and other structures. With this option, a metal frame is arranged on the outside of the railing.

General rules

First of all, when installing, you should adhere to a certain angle of inclination, which is usually equal to the geographical latitude. Observance of the azimuth matters. For the northern hemisphere, it is 180 degrees.

The diagram shows an unshaded area

If snow falls, the efficiency of the system can be reduced to zero, therefore easy access to cleaning must be ensured. You don't have to worry about this if the panels are fixed on the side surface at an angle that is close to 90 degrees.

Fastening panels to special brackets

When mounting a large number of plates arranged in rows on inclined structures, it is necessary to avoid shading the elements with each other. The distance between the lines must be sufficient.

Determination of the collector tilt angle when installing on the ground

On pitched roofs, elements can be placed close to each other

Summarizing

Although the cost of a set of solar panels for a home is quite high, the systems are beginning to be actively used by individual developers of different categories. They are often combined with other options, especially if there is no centralized network nearby. This is one of the environmentally friendly ways to obtain electrical energy.
