Estimated ROI & Value Proposition
(Illustrative calculation based on US commercial rates)
📊 Sample Scenario (Avg. Rate: $0.28/kWh + Demand Charges):
- Daily Solar Self-Consumption: ~1,300 kWh × $0.28 = $364/day
- Annual Energy Savings: ≈ $132,860
- Demand Charge Reduction (Peak Shaving): ~$15,000–$40,000/year
- Backup Power Value: Avoided downtime costs (industry-dependent)
- Estimated Payback Period: 4–6 years (with applicable incentives)
