That’s a solid negative. Sorry you’re being downvoted to hell. You might have some points we could all talk about.
Thanks. I do not take it personally at all.
PV isn’t super efficient. It’s great on a rooftop because the space isn’t being used for anything else, but for grind-scale there are other solar options, such as concentrated solar thermal arrays that drive heat engines.
Solar thermal systems can also store and retrieve excess energy using molten salt, allowing load balancing without needing batteries.
This. mirrors focused on a boiler work best, but then you get random fried birds…
