A photovoltaic installation is composed by a generating group, is formed by an extension of photovoltaic solar panels, a regulator of load, an accumulating group and an investor.
During the hours of insolation, the photovoltaic panels produce electrical energy in form of DC that is stored in the storage cells. At the moments of power consumption, the storage cells provide this one electricity, having to be transformed into alternating current by the investor, to the receivers.
Photovoltaic solar panel
He is the one in charge to transform the energy that arrives to us from the sun in electrical energy. For it one is based on the photoelectric effect, and needs that the rays of the sun affect their surface perpendicularly.
Load regulator
Its main function is the one to protect to the storage cells of an overload when these totally are loaded. Also they protect them of a sobreunloading, since when very they are unloaded, to yield a little load it means an irreparable damage.
Storage cell
It stores electrical energy that, like the batteries of a car, can give back when the user requires it.
Investor
Its purpose is the one to transform the originating DC of the storage cells into alternating current for the domestic use.
What is the photoelectric effect?
The photoelectric effect is him that it allows the direct conversion of rays of the sun (light) in electricity. When the rays of the sun affect a receiving surface, normally of silicon, in her is generated a potential difference (voltage) that can suitably be taken advantage of connecting electrodes.
Types of photovoltaic solar panels
- Crystalline
- Policrystalline
- Amorphous
