Spurred on by some postings in another thread I figured now is a good time to start one dedicated to this subject. There have been several mentions of interesting options here and there on the forum in the past. I remember being especially interested in Robert Gransin’s geothermal installation.
We have had solar panels powering our houses for the last eight years or so. It is an immensely liberating feeling to know that, not only are we not dependent on an outside source for electrical power, but all the power we use is clean, renewable and does not use any fossil fuel.
We just had a 7.2 kW Tesla system installed on our newest house. This time we included two Powerwall batteries which can store up to 27 kW. This means that during the day the solar panels feed the house and recharge the batteries which then power the house at night. These days, with the lockdown in place, there is something really comforting in knowing that even if the power grid gets to be disrupted we are completely independent of it.
Cost wise, the system retailed for $35k including installation in December 2019. It came with a 30% tax credit which we got back recently, making for a net cost of about $24k.
