The idea is the important part. The details (wiring schematics and so on) are not. The cost of solar is rapidly approaching where you’re prepaying for your energy for the rest of your life with a few thousand dollars. You can get solar panels for 10 cents/watt today, for example. That price will potentially continue to decline (historically, price has declined ~20% for every global doubling of PV manufacturing capacity).
I think the details are actually important to the idea. Mainly this green brag doesn't seem to add up. The battery system is crucial.
While there's a bit about needing to replace it in 10-20 years coming out to a $83/month, this is essentially burying the $15,000 bill coming.
Also, unless their battery system is wildly over provisioned at the moment, you can't just add a bunch of new panels. Are they selling back to the grid? I don't think so, they mention grid independence wrt natural disaster. Do they have some sort of system to heat the water in the day only? Did they just take the name plate capacity of the system and multiply it by 40 years? who knows?
These "details" will make anyone buying into their big idea quite frustrated.
I also don't understand the part about chopping wood. Yes it's probably a idilic bit for the story, but that's almost one of the worst fuel sources. Dangerous, carcinogenic, and polluting.
edit: yes in the footnotes, burning wood. Getting rid of that would be the number one way to improve their impact on the earth and their community.
