The Calculation Engine
No averages. No hidden math. Just transparency.
1. Hyper-Local Accuracy
We don't use a flat rate. We detect your state (e.g., "Maharashtra") and apply the exact 2025 tariff Slab for that region.
Source: State Electricity Regulatory Commissions (SERC) Tariff Orders 2024-25
2. Government Subsidy
We automatically apply the Central Government's PM Surya Ghar: Muft Bijli Yojana subsidy to your estimate.
Available for residential homeowners with a valid electricity connection. Source: MNRE 2024-25.
3. 25-Year Simulation
Real savings aren't flat. We simulate the next 25 years considering rising electricity costs and panel aging.
Based on historical WPI (Fuel & Power) and Tier-1 Solar Panel warranties.
4. Why Not "Zero Bill"?
Even with 100% solar generation, most utility bills include fixed demand charges and meter rent that cannot be offset by solar export credits.
We cap savings at 90% of your bill to account for unavoidable fixed costs. Practicality > Hype.
5. The "Urgency" Metrics
Avg thermal power plant coal consumption (CEA/PowerLine)
Consumptive water use in thermal cooling towers (MOEFCC/CSE)
6. Real World Impact
Cars Off Road
Based on avg Indian car emission of 1.21 tonnes CO₂/year (ICCT India).
Homes Powered
Based on avg Indian urban household consumption of 90 kWh/month (Prayas Energy Group).
