This could be the way of the future.
It most certainly will be.
Good news indeed.
These are pricey. I checked a different brand and they are 1200 per square just for the shingles. Add for electrical, the time consumption of installation, plus the fact that the photovaltaic cells are a maintenance item…Its probably not worth it.
I have checked into installing them for a customer. Once he seen the price of the materials, he said “forget it”.
