Module performance is generally rated under standard test conditions (STC): of 1,000 , solar of 1.5 and module temperature at 25 °C. The actual voltage and current output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage at which the module operates. Performance varies depending on geographic l. . A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of directly into by means of the . It is a form of photoelectric cell, a device whose electrical characteristics (such as , , or ) vary when it is exposed to light. Individual solar cell devices are often the electrical building blocks of , kn.
