- ori_b 11y ago10% efficiency is about right for low cost solar cells that have been out in open air for a while. 20% is about right for affordable single crystal cells, and the theoretical maximum efficiency for silicon is 33%. Getting significantly better than 10% is very expensive. Getting beyond about 25% is currently well beyond feasible for large scale power generation.
- mohawk 11y agoMost new panels announced these days top 20% efficiency[1]. Output is guaranteed to 90% after 10 years, 80% after 20, real world often better[2].
