Solar Panel Output in the Real World: 7 Factors That Reduce Efficiency
A solar panel rated at 400 W does not necessarily produce 400 W when installed on a rooftop. Its rated power is measured under Standard Test Conditions (STC), which specify a solar irradiance of 1,000 W/m², a solar cell temperature of 25°C, and a defined reference solar spectrum. Actual outdoor conditions rarely match all these … Read more
