Frequently Asked Questions

light_modeWhat is the cost of a 1 kW solar system in India in 2026?expand_more

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.

light_modeWhich state has the cheapest solar installation cost?expand_more

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.

light_modeIs solar system cost different in Delhi vs Rajasthan?expand_more

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.

light_modeHow much subsidy can I get on solar in 2026?expand_more

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.

light_modeWhat is the payback period for a 3 kW solar system?expand_more

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.

light_modeCan I install an off-grid system in an urban area?expand_more

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.

light_modeWhat qualifications do I need to become a solar engineer in India?expand_more

A degree in Electrical, Civil, or Mechanical engineering is preferred, supplemented by professional certifications in Solar PV Design and software like PVsyst or AutoCAD.

light_modeWhich solar software should I learn for a career in solar energy?expand_more

PVsyst is the industry standard for energy yield estimation. Additionally, learning Helioscope for layout design and AutoCAD for detailed engineering drawings is highly recommended.

light_modeDoes IISE provide placement support after solar courses?expand_more

Yes, IISE provides dedicated placement assistance, resume building workshops, and connects certified professionals with our network of 500+ solar installation partners across India.

light_modeHow do I apply for PM Surya Ghar Yojana subsidy?expand_more

Applications are submitted through the official national portal (pmsuryaghar.gov.in). You will need your electricity consumer number, a photo of your roof, and details of the registered vendor you choose for installation.
