Understanding Your Savings
How we calculate your solar savings and what the numbers mean for your home.
How We Calculate
Daily generation = kW × 5 units/day. Monthly = Daily × 30. Annual = kW × 5 × 365. Based on Satyajan field data across Hyderabad installations.
Payback Period
System Cost ÷ Annual Savings. Flat pricing of ₹50,000/kW. A 3 kW system costs ₹1,50,000 and typically pays back in 4–6 years.
Long-term Benefits
25-year projection with 0.7% annual panel degradation. Solar panels carry a 25-year performance warranty — after payback, electricity is nearly free.
Environmental Impact
India grid emission factor: 0.82 kg CO₂ per unit. A 5 kW system avoids ~9,125 units/year — saving ~7,483 kg CO₂, equal to planting 345 trees annually.
