Battery Benefits
Peak Shifting: Charge during off-peak, discharge during peak hours
Backup Power: Keep essentials running during outages (not included in ROI)
Solar Storage: Store excess solar for evening use
Use this solar battery storage roi calculator to compute solar & energy results from your inputs.
Formula
Daily savings = kWh stored × (Peak rate - Off-peak rate) Monthly savings = Daily savings × Days used Annual savings = Monthly savings × 12 Total investment = Battery cost + Installation Cycle life reached = (365 × Years) / Cycles Payback period = Total investment / Annual savings ROI over lifespan = ((Annual savings × Years) - Investment) / Investment × 100
