Experts said the heat may not be such a boon from a solar energy perspective. Yes, sunny
According to Professor Alastair Buckey of the University of Sheffield, solar panels are most efficient in the spring, when the air is cool and the skies are really clear.
The fact is that solar panels work,by absorbing light energy and using that energy to "excite" electrons. An electric field is then created, allowing the electrons to flow as electricity. The greater the light intensity, the greater the flow of electricity. But the hotter the panel, the more electrons are already in an excited state before the photon hits, which reduces its efficiency.
Modern hybrid solar panels are designed to be less affected by heat, but they can still lose 10% of their rated efficiency on hot days.
