No, not at all. They can be adequately shielded from the elements, they don't need to last so incredibly long, and even currently priced Li/ion batteries make economical sense today in given scenarios.
What's your rationale for these criteria?
- donny2018 3y agoBecause I live in a third world country which is also very sunny, dry and hot like Arizona in the US. And while solar has become cheap enough that our utilities are starting implementing it, the storage is still too expensive if you want GWh scale storage. It can literally cost billions, and considering we may need to replace it in like 5-10 years, it is not a viable solution for us. We just can’t afford it.
