Could be useful

 

The better solar panels get, the more useful they'll be.

Especially if they put them over parking lots,  as I've suggested.

This Guardian article describes how solar panels are getting better.

‘Revolutionary’ solar power cell innovations break key energy threshold

"The breakthrough is adding a layer of perovskite, another semiconductor, on top of the silicon layer. This captures blue light from the visible spectrum, while the silicon captures red light, boosting the total light captured overall. With more energy absorbed per cell, the cost of solar electricity is even cheaper, and deployment can proceed faster to help keep global heating under control.

The perovskite-silicon “tandem” cells have been under research for about a decade, but recent technical improvements have now pushed them past the 30% milestone. Experts said that if the scaling-up of production of the tandem cells proceeds smoothly, they could be commercially available within five years, about the same time silicon-only cells reach their maximum efficiency."

Conceptually, it's not hard to understand.
