EXPLORE SOLAR DATA

Photovoltaic technology uses devices called solar cells to change light energy directly into electrical energy. Many cells make up one panel. Two or more panels make an array or system. Each system is given a rating based on a one-time test performed by the manufacturer. This performance rating tells us how much energy the system could produce under ideal conditions. But photovoltaic arrays rarely operate under ideal conditions. Their output is almost always less than their rating.

What factors affect the power output of a PV system? Explore data from actual solar sites to find out.
