The ability of the system to be completely independent of grid power. Stand-alone systems are highly desirable in situations where the utility grid does not exist, is unreliable, or is too costly to connect due to distance.

Solar energy begins with the sun. Solar panels (also known as "PV panels") are used to convert light from the sun, which is composed of particles of energy called "photons", into electricity that can be used to power electrical loads.

An off-grid solar inverter manages the conversion of DC electricity produced in the solar panels into AC that can be used to run your home.

A device that reserves energy for later consumption that is charged by a connected solar system. The stored electricity is consumed after sundown, during energy demand peaks, or during a power outage.

Solar water pumps are specially designed to utilize DC electricity from solar panels. The pumps must work during low light conditions, when power is reduced, without stalling or overheating.

A solar light does what a normal light does, only it draws power from the sun in order to function, while regular lights require electricity.
