Photovoltaic effect

The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.

Photovoltaic (PV) Solar Panels

Under typical UK conditions, 1m 2 of PV panel will produce around 100kWh electricity per year, so it would take around 2.5 years to "pay back" the energy cost of the panel. PV panels have an expected life of least 25 to 30 years, so even under UK conditions a PV panel will generate many times more energy than was needed to manufacture it.
