Modeling shows the true cost of heat on solar PV system performance

It was already known that PV systems dislike high heat, which is clearly awkward when they depend on the biggest heat source in the *solar* system in order to be of any use. This study tries to quantify the problem in more detail. On the face of it, carpeting desert regions with solar panels looks less than ideal.

Lowering the operating temperature of solar panels by just a few degrees can dramatically increase the electricity they generate over their lifetime, KAUST researchers have shown.

The hotter a panel gets, the lower its solar power conversion efficiency (PCE) and the faster it will degrade and fail, says TechXplore.

Finding ways to keep solar panels cool could significantly improve the return on investment of solar-power systems.
