How To Check Solar Panel Efficiency. Heat High temperatures reduce the efficiency of solar panels. In a heatwave solar panels can reach 65 degrees and this can reduce power by 20 compared to panels that are at 25 degrees.
Remember to look at the power tolerance as although the name plate rating might be 245W the power tolerance will tell you how many more or less Watts a the STC the panel. Solar Panels are the number one item which will affect your solar panel efficiency and overall output. High temperatures reduce panel efficiency.
Set Multimeter to DC.

Many people skip testing solar panels and fail to check their panels output. In a heatwave solar panels can reach 65 degrees and this can reduce power by 20 compared to panels that are at 25 degrees.
