When computers were new, only rich organizations like governments, banks, and large corporations could afford them. Now you can buy a raspberry pi for close to nothing.
Photovoltaics (PV) is not a new technology. It’s been in production-state since the 50’s and powering percentages of some countries for at least the past ~5 years.
Adopt the existing, proven and cost-effective implementation of PV (~3’ x ~5’ aluminum framed panels).
Waiting on Elon to figure out boutique solar so the affluent can all install it first and drive mass adoption (decade?) stalls PV development as much as the US tariff on Chinese-made solar!
