Efficiency
A measure of a solar panel's ability to convert sunlight into electricity. A higher percentage means the panel generates more power from the same amount of sunlight.
Kilowatt-Hour (kWh)
A unit of energy. It represents the amount of electricity consumed or produced over time. Your utility bill charges you per kWh used. Solar systems are designed to offset your kWh usage.
Photovoltaic (PV)
The technology that converts sunlight directly into electricity using semiconductor materials. Solar panels are also called PV panels or PV modules.
Watt (W) and Kilowatt (kW)
Units of power. They measure the instantaneous rate of energy production or consumption. A solar panel's output is rated in watts (e.g., 400W). A system's size is in kilowatts (e.g., 8.2 kW).
AC (Alternating Current)
The standard form of electricity used in your home and by the grid. Solar inverters convert DC (Direct Current) from panels into AC.
DC (Direct Current)
The type of electricity produced by solar panels. Inverters convert DC into AC (Alternating Current) for use in your home and on the grid. Batteries also store energy as DC.
