Solar panel efficiency. Solar panel efficiency is determined by testing panels at Standard Test Conditions (STC), using a temperature of 25°C and an irradiance of 1,000 W/m 2 – the equivalent of a sunny day with incident light hitting a sun-facing surface tilted to 37°. A solar panel efficiency of 15% with a 1m 2 surface area would produce 150 Watts under these test conditions.
