For lead-acid it could be $0.20 or more per KWH, making "free" solar as expensive as grid power. $100 / 500 = $0.20. Lithium, especially LiFeP04 rated for thousands of cycles, promises storage costs in the range of $0.05 per KWH. https://www.amazon.com/LiFePO4-4000-15000-Lifetime-Application-Trolling/dp/B0BJ78JZ2B/ref=asc_df_B0BJ78JZ2B? $200 / 4000 = $0.05. -------------------------------- 4000 daily cycles at 100% DOD is almost 11 years, beyond the claimed 10 year lifespan. If the battery performs as specified the longer life at lower DOD may not be useful.
