A photovoltaic system, also known as a Solar PV power system, or PV system, is a power system designed to supply usable electric power by means of photovoltaics.
It consists of an arrangement of several components, including solar panels, cables and relevant additional equipment, like an inverter (when grid connected) or a battery (in case of a stand alone system).
Sun & Solar Energy
The sun produces an enormous amount of energy. The energy from the sun is produced from deep within its core, where high pressure causes over four million tons of hydrogen to be converted to helium every second through the process of nuclear fusion. In one hour enough sunlight hits the earth to power our world for one year.
Panel & Inverter
Photovoltaic, or "PV" Solar panels convert some of the energy from the sun into electricity. A typical solar panel contains many individual solar cells. Light hitting the solar cells causes the release of electrons, resulting in a direct, or "DC" current, similar to the electricity produced by a flashlight battery.
Meter & Grid
The grid is the network of power lines that moves electrical energy from where it is produced to where it is used. Distributed solar power systems are located on or near buildings where the energy is used, reducing the load on the grid and nearby traditional power plants. On sunny days, power meter may actually run backwards as excess power flows back onto the grid to help power nearby homes and businesses.
A Solar PV system uses PV modules to convert sunlight into electricity. The system can be located anywhere exposed to sunlight, including rooftops, verandas, building façades, the ground, parking lots, etc.
Systems are typically connected to the local utility grid to provide additional electricity for users’ daily use.
Most rooftops, including concrete, color steel, and tiled roofs can be used for PV installations, but the load bearing capacity must meet the panel weight requirements.
