Net Metering Savings Calculator
Implementation Specifications
This calculator is planned and documented. The formulas and guidance below are ready for implementation.
Required Inputs
- System production (kWh/month)
- Home consumption (kWh/month)
- Grid export rate ($/kWh)
- Grid import rate ($/kWh)
- Self-consumption rate (%)
Formulas & Calculations
Self-consumed = Production × Self-consumption %
Exported to grid = Production - Self-consumed
Imported from grid = Consumption - Self-consumed
Export credits = Exported × Export rate
Import costs = Imported × Import rate
Net monthly cost = Import costs - Export credits
Monthly savings = (Consumption × Import rate) - Net monthly cost
Status: Specification complete, implementation pending
To implement: Create app/components/calculators/net-metering-savings-calculator.tsx and register in app/lib/calculator-registry.ts
