Solar panel

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.

Solar arrays: What are they & why do you need them?

To create solar energy, sunlight must hit your panels'' photovoltaic cells. The sunlight sets electrons in motion, producing direct current (DC) electricity. Your array is connected to an inverter or multiple inverters, which convert the DC electricity generated by the solar cells in your panels into usable alternating current (AC) electricity.
