How do PV Solar systems work?

A photovoltaic solar cell uses silicon layers to convert sunlight into electricity; arranged in modules or panels, it can save about 59% on electricity bills, pays for itself in 7-10 years, and lasts over 25 years.

A photovoltaic solar cell converts solar energy directly into electrical energy, using photovoltaics. These facilities allow you to save approximately 59% of your electricity bill and are usually repaid in 7-10 years, when their useful life is usually more than 25 years. But what is exactly a photovoltaic cell?

Photovoltaic cells are layers of silicon "doped" with phosphorus and boron, which, thanks to solar radiation that originates from the sunlight, creates a flow of electrical energy, through the “release” of electrons, which leads to a voltage difference (volts) between the two layers. To get usable performance, it's common to arrange them on a module (or panel) so that the voltage matches a usable DC (direct current) system.

The energy generated in DC form is transformed into AC (alternating current) that can be used directly in electrical devices, stored in batteries or transported through the transmission network to be consumed.
