This is fantastic. Looking at the absolutely massive cost differential between DIY and full-service solar installers, the DIY option looks pretty pretty tempting. My main concern was 1) actually getting through the local permitting process, and 2) what a potential purchaser would think of a DIY system when I go to sell the house.

Seeing that somebody has done it is very inspiring, and if I didn't see a high chance of moving in the next 5 years I'd be on it tomorrow.

It’s a true shame that the public utility commission is so corrupt that we lose the obvious economies of scale from grid-scale installations of same in favor of expensive rent seeking by a state-sanctioned monopoly.

I also have 60kWh of batteries in my kitchen, but for the average person who doesn’t want to deal with this stuff, having to admin part of the power grid is a tragic waste.

If the PUC and power company weren’t bastards, this could all be in a giant field somewhere staffed by a tiny fraction of the people who have to waste their lives dealing with it in their garages. So many unnecessary struts, so much caulk and EPO switches, so many inverters.

I'm still curious what you'd need a rack consuming 1kw for… in your garage. From the photo, it looks like lots of storage(?).

1kW is less than a toaster, fwiw.

I draw 1-1.5kW for my servers in a spare bedroom. It’s not a lot of spindles/cores, just a few dozen.

Having done some work around net zero policy I am increasingly convinced that this is the way forward, and indeed that this will be the way things are done normally maybe 10-20 years from now. The concept is called "distributed generation" and in UK each distribution network keeps an "embedded capacity register" which is basically all the distributed energy resources that are connected to the grid at distribution level (i.e. in the local area). Over here the national grid largely operates at or over capacity, which is a very serious problem for the immediate future, especially as more and more power is drained by compute-heavy infrastructure (data centers and such). Distributed generation is an attractive solution for households regardless of which angle you look at it from.
