input energy from the sun. In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell.

Nov 17, 2017· Intro. In a previous post in this series I explored the patterns in a solar panel data set. It turned out the panels can warm up to a hot 47°C. The negative effect of temperature on the efficiency of solar panels is well known and documented.Generally, panels are expected to perform optimal up to 25°C, when panels get hotter than this a maximal power output penalty is paid.
Firstly, it is important to stress that efficiency of a solar panel is a matter of area, not power. A 10% efficient 100W panel and a 20% efficient 100W panel will both produce exactly the same amount of power. However, you should expect the 20% efficient solar panel to be half the total size of the 10% efficient panel.
