Alternating Current (AC):
A type of electricity in which the electrical current moves back and forth rapidly, switching 60 times per second. The type of electricity generally delivered to businesses and homes is alternating current electricity.
Combiner: The component of a solar photovoltaic system that unites the electrical currents generated by the solar panels into a single source of direct current electricity.
Direct Current (DC): A type of electricity in which electrical current moves only one direction. This is the type of electricity supplied by batteries and solar panels but is not the type of energy supplied by the grid.
Inverter: A key element in any solar photovoltaic system, the inverter transforms direct current electricity into alternating current electricity.
Kilowatt Hour (kWh): The standard unit of electrical energy. Your electricity bill is measured in Kilowatt-hours. 1 kWh is equivalent to the amount of energy consumed by ten 100-Watt light bulbs burning continuously for one hour.
Megawatt Hour (MWh): 1 megawatt hour (MWh)= 1,000 kWh.
Net Metering: The arrangement by which excess electricity produced by a customer’s solar photovoltaic system is supplied (and sold as a credit) back to the utility grid.
Power Purchase Agreement (PPA): A long-term contract between Just Energy and its customer stating that the customer will purchase all electricity generated by the solar photovoltaic system at pre-determined rates.
Photovoltaic (PV): Literally light-voltage (photo-voltaic), it is a term meaning the conversion of light into potential energy (voltage). The basic process underlying solar power.
Photovoltaic (PV) Cell: The fundamental building block of solar panels.
Renewable Energy: Energy that is naturally replenished every day. Fossil fuels are non-renewable sources of energy, because as they are consumed, the earth does not regenerate the supply.
Solar Array: A group of solar panels.
Solar Panel: The basic installation component of a solar photovoltaic system. Solar panels are approximately 10 square feet.
