#2Good analysis. And kudos to the author for saving money. But still 21.6MWh per year excluding solar production seems too high for a household. I use electric heating and drive an electric vehicle, and my household annual energy consumption is about one fifth of that.

#3The US clean energy tax credit is only available for equipment installed on or before Dec 31, 2025 https://www.irs.gov/credits-deductions/residential-clean-ene...
As a result, more used solar should become available on ebay. I'm excited to see what I can do on a shoe string budget.

From the article: "My wife and I both drive electric cars"
That probably explains it.

maybe saving money they used more - in other words Jevon's paradox https://en.wikipedia.org/wiki/Jevons_paradox
thus perhaps leading to more global warming

That’s about double the average household so I would imagine spending that money and effort into energy efficiency would pay off way better that solar and batteries.

20MWh is around what my house used in both 2024 and 2025.

Don't be surprised when the answer is "not much". Apply supply and demand to electric power generation. If your grid rate is getting hiked then so is the market price of used solar.

I can’t see any mention of hot water or cooking in the article, which may be relevant.
I was stoked at the power saving from turning off an espresso machine a bit sooner, a swapping out a nuc to a Mac mini.
Maybe there is a bit coin mining operation in his basement?

#10Why do people still go for tesla powerwalls when you can get BYD batteries with 70%+ more capacity for cheaper ?
You can buy a BYD HVM 22.1 kWh for 6000 euros now (£5200) vs powerwall 2 13.5kwh for 7000 euros.
