Photovoltaic Energy

Photovoltaic energy is energy obtained from any visible light and is used for generating electricity. In contrary to solar energy, which uses only energy radiated from the Sun, photovoltaic cells (commonly referred to as just photovoltaics) capture any visible light and convert it into energy. Thus photovoltaics are able to produce energy even during the night from moonlight.

Photovoltaic energy is used for generating electricity, while the device necessary for exploiting photovoltaic energy is the photovoltaic module which consists of photovoltaic cells. Photovoltaic modules are in turn linked into a photovoltaic array because the energy generated by one photovoltaic module is not enough to satisfy the needs of a household. Photovoltaic energy system are relatively new but have became very popular in recently, mostly because they don't only use sunlight to generate energy like the solar cells but it can also produce electricity on a cloudy day or at night.

Unfortunately, the price of photovoltaic arrays is very high and for that reason photovoltaic energy at the moment is not affordable for everyone although its one of the easiest and cleanest way to produce the energy. For that reason many households which opt for photovoltaic arrays do not get much energy solely from a photovoltaic energy system and still require an additional source of energy.
