In 2026, a 1 kW solar system typically costs between ₹60,000 and ₹80,000 before subsidies, depending on the module technology (TopCon/Bifacial) and inverter type used.
Rajasthan currently offers some of the most competitive pricing in India, starting at approximately ₹42,000 per kW, due to high solar irradiation and a mature local installer ecosystem.
Yes, Delhi's average cost is slightly higher at ₹49,000 per kW compared to Rajasthan's ₹42,000, primarily due to logistics, labor costs, and differences in state-level incentives.
Under the PM Surya Ghar scheme, you can receive up to 40% Central Financial Assistance (CFA) for systems up to 2 kW, and 20% for the additional capacity between 2 kW and 3 kW.
For a typical 3 kW on-grid system with subsidy, the payback period is approximately 3 to 4 years, after which the electricity generated is essentially free for the remaining 20+ years of the system's life.
While technically possible, off-grid systems are generally not recommended for urban areas with stable grid access due to the high cost of batteries and the inability to export excess power via net metering.
A degree in Electrical, Civil, or Mechanical engineering is preferred, supplemented by professional certifications in Solar PV Design and software like PVsyst or AutoCAD.
PVsyst is the industry standard for energy yield estimation. Additionally, learning Helioscope for layout design and AutoCAD for detailed engineering drawings is highly recommended.
