FAQ
How is first-year efficiency calculated?
(Energy discharged) ÷ (Energy charged) × 100%, measured monthly with seasonal adjustments.
Can we recover lost efficiency after the first year?
Partial recovery is possible through cell balancing and software updates, but prevention remains crucial.
What's the industry benchmark for acceptable loss?
Top-tier systems aim for <3% capacity degradation and <2% round-trip efficiency drop.
