Estimated ROI & Value Proposition
(Illustrative calculation based on US industrial/utility rates)
📊 Sample Scenario (Avg. Rate: $0.32/kWh + Demand Charges):
- Daily Solar Self-Consumption: ~6,000 kWh × $0.32 = $1,920/day
- Annual Energy Savings: ≈ $700,800
- Demand Charge Reduction (Peak Shaving): ~$80,000–$200,000/year
- Backup Power Value: Avoided downtime costs (e.g., data center: $100k+/hour; manufacturing: $10k+/hour)
- Estimated Payback Period: 3–5 years (with applicable federal/state incentives, e.g., ITC, SGIP)
