I'd absolutely do it now. The price of solar has been beneath that of racks, mounts, wiring and installation for a while now. Even assuming a major breakthrough

I'd absolutely do it now. The price of solar has been beneath that of racks, mounts, wiring and installation for a while now. Even assuming a major breakthrough your costs probably wont change that much because panel cost isnt a big % of what your costs will be anyway. There's also a risk that supply chain bottlenecks/cold war with china will drive up the cost & your electric bill is only gonna go up.
