House batteries are a much smaller market than batteries for EVs (at least right now). They also have other supporting components, safety features, etc. that add to the price. Since they’re normally installed as part of a solar install, they also usually qualify for a tax credit (between federal and state this can be over 50%) which further drives up the price because the vendor is able to capture a large chunk of the tax credit as profit.
- zihotki 4y agoActually they require less safety features (they don't need to be crash-safe) and can use heavier batteries and components. Which should make them cheaper than EV's batteries in theory. But that market is in early stages with all associated downsides of early adoption, I agree with that.
- boringg 4y agoThere are other features for a home battery. There are shutoffs. Each job is a bit custom on the install + electrician work. Retail markup. You can use your car battery - though you will degrade that car battery much faster which is probably the battery you want to have better performance.
- AtlasBarfed 4y agoThat's a failure of government with home solar. Home solar + storage adds community-level resiliency in disasters and will reduce the grid load needed for home EV charging and industrial level charging used by electric tractor trailers. It should be a major complimentary effort of governmental policy along with grid scale solar/wind, grid scale storage, and whatever load leveling we can effectively decarbonize. Good luck getting that through our deadlocked government. Especially since
