To evaluate <energy system> systems it is important to be able to understand the key concepts and equations. The following section presents common equations you are likely to encounter in a <energy system> system along with details.
Usable Energy (UE) - This equation is used to calculate the amount of usable energy available to the photovoltaic solar collectors in kWh/ft2-yr.
PC = Production Capacity (kWh/W-yr)
SP = Solar Panel Rating (W/ft2)
nI = Inverter Efficiency
