Common Mistakes to Avoid
Common Mistakes to Avoid
Ignoring battery degradation in long-term projections
Lithium-ion batteries degrade 2-3% capacity per year. By year 10, usable capacity is 70-80% of original. Model decreasing annual savings over the battery lifetime, not flat projections.
Assuming 100% depth of discharge
Most residential batteries operate at 80-90% DoD to preserve cycle life. A '13.5 kWh' battery delivers 10.8-12.2 kWh usable per cycle. Use usable capacity, not nameplate.
