A properly sized system can offset 80–100% of electricity usage. Savings = production (kWh) × your rate, minus any remaining connection fees.

Monthly savings math

Example: 6 kW system producing 8,000 kWh/year at 15¢/kWh saves ~$1,200/year ($100/month).

  • Rates rising 2–4%/year increase savings over time
  • Compare payback period after ITC
  • Check state page for local rate: Arizona
