Putting panels on houses is the least cost effective way to do solar. Every house only has so much space on the roof, you have to work around vents and other obstructions, and the inverters will be smaller (meaning less efficient than one big one). It’s a custom project for every single house.

Conversely, if you buy a field, you can make racks that slap on every panel the same, there are fewer obstructions to work around, and you can buy one big inverter to cover the whole thing. This is where solar gets cheap. Really cheap.

I know everyone wants to stick it to power companies and have energy independence. If you want that, look for community solar projects where everyone pitches in a little to get a larger deployment. If your state or locality is blocking those projects, then start going to campaign events and asking them about. Hold them to it with votes and campaign contributions.
