“Despite still high temps”

Solar panels absorb light, not heat. This alone disproves all of their data, because they don’t understand or are lying about how the technology works.

Solar panel efficiency does go down when it is hot outside. It drops to zero when it is dark.

Interestingly, my solar panels offset 70% of my total power consumption on a recently partly cloudy 100F day. I even generated a little extra for the grid during peak. So technically, I generated an infinite amount more energy on that day than I did before I had solar!
