Adjustable Set Point is a feature allowing the user to adjust the voltage levels at which a charge controller will become active.

Activation voltage is the voltage at which a charge controller will take action to protect the solar batteries.

Activated Shelf Life of a solar battery is the period of time (at a specified temperature) that a charged battery can be stored before its capacity falls to an unusable level.

Solar Absorber/Collector is a device used for capturing solar radiation (usually the heat component). An ideal solar collector should absorb virtually all wavelengths of light that reach Earth’s surface from the sun.

The watt-hour (symbol Wh) is a unit of energy commonly used to measure electricity. One watt-hour is the amount of electrical energy equivalent to a one-watt load drawing solar power for one hour. One watt-hour is equivalent to 3,600 joules.

Voltage is the change in electric potential (meaning potential energy per unit charge) between two positions. The voltage is always measured between two points, for example between the positive and negative ends of a solar panel, or between a wire…

The basic unit of electricity is the Kilowatt hour (kWh). In simple terms, 1 kWh is the amount of solar energy consumed by an electrical device (e.g. an electric heater) that is rated at 1 kW (1,000 watts) for 1…

A tariff is the pricing structure a retailer charges a customer for solar energy consumption. It may vary significantly from locality to locality within a particular country.

Three phase system is designed to supply or use simultaneously three separate alternating currents of the same voltage, but with phases differing by a third of a period. The three phase supply is used to drive heavy loads. The solar…

Trackers are devices that orient the solar panels in such a way as to track the sun. They are used to maximise energy capture from the sun. They are mounted along with solar panels. Solar trackers come as single axis…
