During the past months, solar or photovoltaic panels have become a hot topic because the energy crisis has astronomically raised prices for electricity and gas . As a result, homeowners want to become less dependent from the electricity production. One of the most common solutions is to build a photovoltaic power plant on the roof of their house.

With self-produced electricity, you can save up to 60% on energy costs. In addition, this production is environmentally friendly and, in many countries, supported by governments as “green projects”. You can store such electricity either in water heating or accumulate it in batteries and then use this electricity in the evening.

As soon as sunlight hits the photovoltaic panel, the panel creates a direct current of electricity, which we can then use. This is taken care of by other components of the solar power plant, such as an inverter. The inverter creates alternating current from direct current, the same as we have at home in the sockets. Thanks to the inverter the electricity from PV panels in the house flows everywhere where needed - it is the brain of the home solar plant.

Photovoltaic panels work best when they are exposed to bright sunlight, as perpendicular as possible. That’s why their optimal slope is very important - in our conditions it’s approx. 35˚ - 45˚. A solar power plant will produce electricity even if it’s cloudy because the photoelectric effect simply works in any light. But expect only a small part of full power in such conditions.
