Solar Battery Storage ROI Calculator
Implementation Specifications
This calculator is planned and documented. The formulas and guidance below are ready for implementation.
Required Inputs
- Battery cost
- Installation cost
- Battery capacity (kWh)
- Daily kWh stored/used
- Peak electricity rate
- Off-peak rate
- Days per month used
- Battery lifespan (years)
- Cycles
Formulas & Calculations
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
Status: Specification complete, implementation pending
To implement: Create app/components/calculators/solar-battery-storage-roi-calculator.tsx and register in app/lib/calculator-registry.ts
