Question 1

How is solar EMI calculated in India?

Accepted Answer

Solar EMI uses the standard formula EMI = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the tenure in months. D'Clair Energy's calculator applies 8% p.a. on loans up to ₹40,00,000 and 8.5% p.a. above that, over 5, 6 or 7 year tenures.

Question 2

What is the PM Surya Ghar subsidy amount?

Accepted Answer

Under PM Surya Ghar, residential rooftop solar using DCR (ALMM-listed) panels receives ₹30,000 for systems up to 1 kW, ₹60,000 up to 2 kW, and ₹78,000 for 3–10 kW. Systems above 10 kW, commercial and industrial projects, and non-DCR panels are not eligible.

Question 3

What is the difference between DCR and Non-DCR solar panels?

Accepted Answer

DCR (Domestic Content Requirement) panels are ALMM-listed and manufactured in India, which makes them eligible for the PM Surya Ghar subsidy. Non-DCR panels are not ALMM-listed and do not qualify for the subsidy, though they may carry a lower upfront cost. Both use identical EMI terms.

Question 4

How much does solar cost per kW in Gujarat?

Accepted Answer

D'Clair Energy prices solar on a tiered per-kW basis: approximately ₹55,000/kW for 1–10 kW, ₹49,000/kW for 11–30 kW, ₹48,000/kW for 31–100 kW, and ₹47,000/kW above 100 kW, before subsidy. Final pricing depends on brand, quantity and market rates.

Question 5

What is the payback period for rooftop solar in India?

Accepted Answer

Rooftop solar in India typically pays back in 3–5 years. The calculator assumes 4 kWh per kW per day (the India average) and factors in your electricity tariff plus annual tariff escalation to estimate payback and total 25-year savings.
