Most of our solar installations include backup storage these days, so batteries are a major component. You may not know this, but there are different types of lithium-ion batteries, based on a wide range pf different chemistries. Tesla and LG chose lithium-manganese-cobalt-oxide (NMC) chemistry. This the same chemistry that led to an LG recall in 2020. We use batteries with lithium-iron-phosphate (LFP) chemistry. Their pricing’s gone down, they’ve become more compact, and they have an established safety record.
