    $50k is a pretty large installation, 18kw-22kw I’d guess for solar only (no battery storage). I’m hoping thats only a max of 100% replacement of electricity sourcing (meaning essentially no net grid consumption after you’re installed). What’s the price per KWh for electricity delivered to your door in St Louis? Its gotta be pretty crazy cheap if you’re that large a consumer of electricity and you’re paying in cash with no battery, and still looking at multiple decades of ROI with the US federal tax credit.

      I don’t remember the kWh specs and price off hand but a decent portion of the cost was that I’m in a 1.5 story that faces S and have a lot of small roofs rather than one large roof so it’d be a bunch of panels that didn’t have full sun most of the day. Which is true of all hundred houses in my subdivision as well. Basically build of the house made this difficult or impossible

        Does that mean a substantial portion of the $50k quoted was setting up lots of panels is many small spaces, (because of the broken up nature of the roof) and that perhaps the system was oversized its electrical capacity because of the assumption that it would only be fractionally efficient because of the substandard angles and shading? I could see that. Certainly roof designs and even large mature trees can make solar unfeasible in those situations…

          Maybe, I was so mad I didn’t even get more quotes, I should really do so but I was expecting 10-20 at most and hearing 50 kinda put me off the prospect for a while. Decided to spend effort on other home improvement we could see instead
