Solar module prices reached a new low this week, says Leen van Bellen, business development manager Europe for Search4Solar, a European purchasing and selling platform for solar products. He tells pv magazine that prices will remain low in the short term.
What? Have you ever had a battery powered device for longer than 2 years?
All of them, plus storage batteries are under much less abuse and are different chemistry that lasts a lot longer.
I didn’t mean they only last 2 years but battery degradation is a pretty common and known thing.
By a quick search I didn’t find any claim of storage battery lifetimes outside of 10-15 years, so there doesn’t seem to be a breakthrough in tech I wasn’t aware of. 15 years is hardly the lifetime of a house, so you certainly don’t “buy only once”.
Solar panels also don’t work indefinitely but their efficiency degradation is more on par with the lifetime of major parts of the building, like the roof itself.
The comparison commodity was Gas. Does something that can only be consumed once even have a lifetime?
