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
