Everything about photovoltaics

Everything you need to know before
investing in a solar installation.

What is photovoltaics?

Photovoltaics is a renewable energy source that allows electricity to be produced in an environmentally safe way.

PV installation is a solution with an investment for many years. Its service life is expected to be 25-30 years. By investing in solar panels, you run out of problems with high electricity bills and become independent of the annual increases in energy prices. The use of an autonomous solar kit is free and long-term, and the installation itself is environmentally friendly.

Silicon photovoltaic cells placed in solar panels convert solar energy into electricity.

It works very simply:

  • A light beam (photon) falls on the silicon plate from which the photovoltaic cell is built.
  • Silicon absorbs light while knocking out the electron, setting it in motion. This movement is the flow of electricity.
  • The production of electricity from photovoltaic panels is constant, to use electricity you must install an inverter, which is the heart of the entire installation. The inverter converts direct current into alternating current.

It is very important when choosing a solar installation to determine how much electricity the house consumes in a year.

It depends on what size of the installation will be suitable and how the payback time will be distributed. It is best to use electricity bills for this. After analyzing the invoices, we can determine the approximate power of solar panels that will be suitable for our home.
