Solar Battery Cost (A Complete Breakdown)
LCOS. 0.214 USD/kWh. 0.417 USD/kWh. As you can see — initially, the price of the lithium-ion battery (LiFePO 4) costs 4X more than the lead-acid battery. However, it lasts much longer and thus it has the lower LCOS. In short, over its lifespan, the lithium battery is two times cheaper than the lead-acid.
