How does 12 years required for this scheme to pay for itself stack up against the typical house battery's lifetime?
- strbean 1mo agoSounds like that's roughly the average usable lifetime for the battery, so you will break even on average.

- Toutouxc 1mo agoRoughly the usable lifetime? Based on what?
- medler 1mo agoThe battery linked in the article (https://eu.ecoflow.com/products/stream-series-solar-battery https://eu.ecoflow.com/products/stream-series-solar-battery) advertises a 15 year lifespan and 10 year warranty. Personally I would expect batteries to last longer than that but 12 years feels fair
- hobo123 1mo agoI think most electric car batteries are still at over 80% capacity after 10 years usage, so hopefully you can use them much longer than that. If you only cycle then in the 20-80% range, they'll last much longer (at least for NMC cells, not sure how LFP works).
- vel0city 1mo agoI'd imagine most electric car batteries aren't fully charging and discharging every day. That makes quite a bit of difference in wear! Tons of EVs these days are being made with what, 200-300mi range of battery pack with some internal buffer as well so they're never really going 0-100%? So what, we'll be generous here about the 20-80% and think 160mi of range used every day. That's 58,400mi of driving per car! The average US car does closer to 14,000mi. Being generous, that's 4x the wear cycles of a normal US automobile.
- Retr0id 1mo agoAlso, as more batteries get added to the grid, the difference between the "cheap" and "expensive" energy prices ought to reduce.
- rsynnott 1mo agoEh, there’s a tension there, becuase on the other hand as more renewable power is added to the grid, you’d expect divergence. Especially in countries which are letting people buy at spot price; that can be horribly expensive, or go _negative_.
