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. 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.
There are two main types of solar panel – one is the solar thermal panel which heats a moving fluid directly, and the other is the photovoltaic panel which generates electricity. They both use the same energy source – sunlight – but change this into different energy forms: heat energy in the case of solar thermal panels, and electrical energy in the case of photovoltaic panels.
