Photovoltaic is the method of generating electrical power by converting solar radiation (photons) into DC electricity (volts) using semiconductors.
The Renewable Portfolio Standard is a regulation that requires the increased production of energy from renewable energy sources, such as wind, solar, biomass, and geothermal.
The Solar Massachusetts Renewable Target program is a state incentive plan developed to replace the SREC program for new solar arrays completed after March 31, 2018.
Solar Renewable Energy Certificates are a renewable energy incentive offered by some U.S. states.
Alternating current is the flow of electric charge that periodically reverses direction. AC is the type of electricity generated and distributed by electric utilities and, therefore, what most businesses and homes use.
Direct current is the unidirectional flow of electric charge. DC is produced by sources such as batteries, thermocouples, and solar cells.
A megawatt is a unit of energy equal to 1,000 kilowatts (1 million watts). It’s often used to define the size or capacity of a solar array.
A kilowatt hour is a unit of energy equal to 1,000 watt-hours or 3.6 megajoules. For constant power, energy in watt-hours is the product of power in watts and time in hours.
