Solar array mounted on a rooftop. 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. These 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 cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
