Solar energy has ceased to be something mythical and unattainable. Increasingly, houses can be seen solar panels, which is a modern alternative source of electricity. There are many reasons for this:
- energy independence from a centralized energy supply system;
- environmentally friendly electricity production;
- the sun is an inexhaustible source;
- saving money;
- availability in any location;
- uninterrupted operation due to parallel operation with mains;
- Easy operation, maintenance, installation on any surface.
Before deciding to install solar cells, you need to consider all the features of such a source of energy. The most relevant for a private country house, although it is also installed in apartment buildings. The location of the house plays an important role in the energy efficiency of the solar installation. The north side, a large number of trees, high buildings nearby significantly reduce the power and amount of sun energy consumed. Therefore, the most efficient solar battery will serve in an open area.
Depending on the amount of electricity consumed, you need to calculate the number of solar panels. If the house is large and it is impossible to ensure this kind of energy by 100%, it can easily be combined with a central power grid. According to the level of illumination and the duration of a sunny day for a particular location, you need to make corrections in the calculations.
Having installed solar panels, you need to be ready to take care of them. Snow, dirt, dust, bird's excrement significantly reduces the amount of sunlight. Therefore, several times a year the panels need to be cleaned and washed. In addition, their service life is not unlimited and is approximately 50 years. After that, they should be replaced, and the old ones should be recycled.
Principles of professional installation of solar panels
There are several types of solar cells: monocrystalline, polycrystalline, thin-film. They differ in power, so the first two are used primarily for domestic purposes, and the latter - in commercial. The equipment is standard and consists of solar modules, batteries, inverter, controller, automatic reserve entry device.
Despite the simplicity of the design, the installation of a solar power plant involves some rules. It is better to entrust this process to professionals. They correctly assess the feasibility of such an event based on the location of the house and solar activity. Next, calculate the required power and number of panels. Select the right combination of solar cells for their effective functioning.
In the second stage, the modules are mounted directly. Most often, a roof is used for this, to which they are easily screwed. From them there are two wires that connect to the electrical panel. The rest of the equipment is installed indoors. The connection scheme is quite simple: high-voltage consumers connect to the inverter, low-voltage - to the controller. Then the entire solar power plant is put into operation. While the sun is shining, the house is provided with solar energy, and after it sets in, the reserve input device automatically connects the power grid and recharges the batteries.
Correctly conducted work on the installation of solar panels guarantee the uninterrupted operation of the system for dozens of years. The main thing is to always shine the sun.
