Solar panels are already so cheap that household solar is mostly about the installation price.
And more people affording their own panels is still a lot more expensive than fixing the grid.
- closewith 1y agoBut batteries aren't, and batteries are both the key technology for load shifting and the biggest expense in modern installations.
- bryanlarsen 1y ago5kWh of batteries is under $1000. That's enough for load shifting for most people. Even if you need several of them, that's still going to be cheaper than installation labor.
- eldaisfish 1y agowhere are you buying 5 kWH of batteries for under $ 1,000? The typical 5 kWh battery in Canada is C$ 3,000 - 4,000.

Server rack style, 1200 USD for 4.8 kWh = $250/kWh. Wall-mount, 14.3 kWh for $3.3k = $231/kWh. These guys seem to be the biggest DIY solar equipment supplier in the US. Afaik you can get batteries from China (AliExpress) for quite a bit cheaper too.
- djrj477dhsnv 1y agoYep I bought several Huawei 4.8 kWh batteries for about $450 each for an off-grid house in SE Asia. They've been working great a year later, running AC throughout the night.
- djrj477dhsnv 1y agoThat really depends on where you live. I set up the batteries and inverter myself, but paid a local installer and his 2 helpers a grand total of $45 to install and ground 10 x 600w panels on my dangerously high metal roof.
