One of the most fun things about blogging is learning as you go. If you like watching an uninformed person slowly get informed, get a fresh cup of coffee, sit back, and enjoy.
I previously discussed Battery storage for the home. Extremely expensive, but available. Update: merely double my costs.
(My math was off. Read to the end for my new calculation.)
Also More followup on the Tesla Powerwall home battery.
To analyze the concept of home batteries and solar power, I’m looking at the concept from the perspective of going off-grid.
I found a few websites that provided some info on the solar array needed. I won’t list the specific sites to avoid causing any unexpected problems, like, oh, exposing commercial businesses to unwanted ridicule.
One site gave helpful tools to calculate how many panels are needed. To go off-grid and cover our actual electricity use last August would call for a 7Kw system. That would involve $18,000 of their panels plus $1,500 or $2,000 for an inverter. Installation and permits are extra.
