What are 3 drawbacks to storing solar energy in batteries?
-
Upfront Cost: High-quality batteries like lithium-ion models can be expensive (but they last longer and perform better).
-
Limited Lifespan: Even top-tier batteries degrade over time, typically after 500 to 1000 cycles.
-
Efficiency Loss: Some energy is lost during storage and retrieval, typically around 5 to 15%, depending on the system.
