I have a startup in solar software, and the big thing that I don't think people here realize is that 64% of the installed cost of solar in the U.S. is soft costs (i.e. not hardware)[1]. The industry is incredibly inefficient when it comes to customer acquisition, marketing, distribution, project development, permitting, monitoring, analytics. etc. There's a huge effort by the DOE[2] and the industry itself[3] to atta…
Earlier quoted context omitted.
If I were mayor, I would require new construction to have 1kw of grid intertied solar per unit.
A 1kW system is horribly inefficient. That's 4 modules, which even in series is not going to get you to grid voltage so you will have to use costly microinverters. Plus you have all the fixed costs of installation, inspection, switchgear, etc. that has to be amortized over a tiny amount of power. Silly. For most circumstances, 4-5kW is going to be the minimum economical installation. There are many people who know ho…
No. And I wasn't making a spec. I'd be optimizing for something else, installed base, know how and a population of contractors kickstarted into action. This was a minimum, not forcing people to ONLY install 1kw.

If we are arguing over buck or boost when it comes to solar penetration we arguing at the wrong abstraction level.
