What rooftop solar actually costs in India this year
A transparent breakdown of panel, inverter, structure and labour costs — and why the cheapest quote is rarely the cheapest system.
A quality 3 kW residential system typically lands between ₹1.8 lakh and ₹2.2 lakh before subsidy. Panels account for roughly 45% of that, the inverter 15%, mounting structure 15%, and the rest is cabling, protection devices, labour and liaison work.
The tempting ₹1.4 lakh quote usually cuts corners on the mounting structure and the cabling — the two components that decide whether your roof survives a decade of monsoons and 45°C summers. A failed structure costs far more to fix than it ever saved.
After the ₹78,000 central subsidy, most homeowners recover their net investment in three to four and a half years, then enjoy two decades of near-free daytime power with a linear performance warranty on the modules.
