Costs $500 + planetary manufacturing costs of the battery, and panel, plus their pollution cost post-use.
Based on constant use, it generates $50 of electricity per year + saves plantary production costs of electricty by traditional means.
So providing the battery and panel don't fail or decline in function, it financially pays for itself after 10 years of constant use, realistically probably more like 8 or 9 years when you factor in rising domestic electricity costs.
Looks like a terrible investment to me. Especially when you factor in the planetary costs of the physical production.
- AdrianB1 6y agoAdding one or 2 more panels would increase the output a lot with a small increase in price, making the financials a lot better. Yes, it is a bad deal as it is now.
- ashtonkem 6y agoThe average payback on whole home solar is 7.5 years, so 10 isn't too far off normal. My problem is that semi-permanent installation at this size is of questionable utility; I don't want to have to juggle my electric usage between this and the regular grid in order to maximize my solar, that sounds incredibly inconvenient. Of course there are solutions to this, but they're not renter friendly.
- im3w1l 6y agoThe comparison should be against consumer cost of borrowing I think. And with a 10% yield it does look like can take a loan and come out ahead.
- falcolas 6y agoI do appreciate that they’re up front about this on their page at least.
