A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries. Solar panels are also known as sol. .
In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist . Though these initial solar panels were too inefficient for even simple electric devices, they were u. .
modules consist of a large number of solar cells and use light energy () from the Sun to generate electricity through the . Most modules use -based cells or . The structural (.
