An inverter converts the electricity generated from a solar system from direct current (DC) to alternating current (AC) for use in the home.

The amount of solar energy that strikes a surface during a specific time period. Measured in kilowatts.

A graph that plots the current versus the voltage from the solar cell as the electrical load (or resistance) is increased from short circuit (no load) to open circuit (maximum voltage). The shape of the curve characterizing cell performance. Three important points on the IV curve are the open-circuit voltage, short-circuit current, and peak or maximum power (operating) point.
