Gurugram receives approximately 5.5 kWh of solar radiation per square metre per day — one of the highest in India. With electricity costs consistently rising and solar panel prices falling by over 80% in the past decade, the economics of rooftop solar have never been more compelling.
A typical 3-bedroom apartment in Gurugram consumes around 400 units of electricity monthly. A 3 kW rooftop solar system, costing approximately ₹1.5–2 lakh after subsidy, can generate 350–400 units monthly — effectively eliminating the electricity bill. Payback period: 3–4 years. System life: 25+ years. HAREDA offers a 30% subsidy on residential solar installations. The question is no longer whether solar makes financial sense — it clearly does.
