Solar PV explained
Solar photovoltaic (PV) panels convert the sun’s energy directly into electricity that can be harnessed directly to power electrical devices or stored for later usage. Large-area rooftops are prime locations for hosting solar PV collection arrays.
Sunlight is made of photons, or subatomic particles of energy. Photons streaming to earth are absorbed by and pass through the material of a solar PV panel, agitating the electrons in the material of the photovoltaic cell. As these electrons begin to move, they are routed into a current, creating electricity. This electricity is then conducted by wire directly into the electrical system of the building to power lights, appliances, etc., or, in some cases, sold back to the regional electricity grid owner.
In many solar PV systems, batteries are used to store electricity for times when the sun is either obscured or not bright enough to generate sufficient power.
