Kerala homeowners in 2026 can claim up to ₹78,000 under the PM Surya Ghar: Muft Bijli Yojana — India's only active central subsidy for residential rooftop solar. A 3 kW on-grid solar system costs ₹1,07,000–₹1,37,000 after this subsidy, with a payback period of 3–5 years. Solar panels in Kerala generate 12–15 units per day for a 3 kW system, even during the monsoon season (generation drops 20–30% but panels continue producing from ambient light). KSEB net metering allows homeowners to bank surplus units and settle them annually at year-end. Systems up to 10 kW do not require battery backup. Installation through an MNRE-empanelled company like Flarize takes 2–3 days. The full process from KSEB feasibility approval to subsidy disbursement takes approximately 3–5 months.

Solar panel prices in India typically range from Rs.20 to Rs.45 per watt, depending on the type (monocrystalline vs. polycrystalline), brand, and wattage. A standard 1kW system costs roughly Rs.30,000-Rs.50,000 before subsidies. Prices have been falling year-on-year due to increased domestic manufacturing. Tip: Always get at least 3 quotes from certified installers and compare price per watt, not total cost.
For a typical Kerala home, a 1kW to 10kW rooftop system is suitable. Estimated costs before subsidy: • 1 kW - Rs.70,000-Rs.90,000 • 3 kW - Rs.1.85-Rs.2.15 lakh (net ~Rs.1.07-1.37 lakh after Rs.78,000 subsidy) • 5 kW - Rs.2.8-Rs.3.2 lakh (net ~Rs.2.02-2.42 lakh after subsidy) • 10 kW - Rs.5.6-Rs.6.4 lakh Tip: Under PM Surya Ghar Muft Bijli Yojana, subsidies of up to Rs.78,000 are available for systems of 3kW and above.
A 5kW solar system in India typically costs between Rs.1.8 lakh and Rs.2.5 lakh for supply and installation. This includes panels, inverter, mounting structure, wiring, and net-metering charges. A 5kW system can generate 18-25 units per day, enough for a 3-4 BHK home. Tip: Payback period for a 5kW system is typically 4-6 years, depending on electricity tariff and sunlight hours in your city.
A 500-watt solar panel (usually a single large bifacial or monocrystalline PERC panel) costs approximately Rs.12,000-Rs.22,000 per panel in India. Prices vary by brand (Adani, Waaree, Luminous etc.) and efficiency rating. Higher-efficiency panels cost more upfront but generate more per square foot.
Prices are broadly similar across India but vary slightly based on local DISCOM rules and labour costs: • Delhi NCR - Rs.38-Rs.46/W (BSES/TPDDL net-metering is straightforward) • Mumbai - Rs.40-Rs.48/W • Bengaluru - Rs.36-Rs.44/W • Chennai / Hyderabad - Rs.34-Rs.42/W • Rajasthan / Gujarat - often 5-8% cheaper due to high solar irradiance and strong state policies
Under net metering, surplus electricity exported to the grid is credited at Feed-in Tariff (FiT) rates, which vary by DISCOM but are typically Rs.2-Rs.4 per unit. Since most DISCOMs are moving to gross metering for larger systems, the effective savings come from offsetting your own consumption, which is worth your full retail tariff (Rs.5-Rs.10/unit depending on your slab).
A 3kW rooftop solar system in Kerala typically costs Rs.1.85 lakh-Rs.2.15 lakh before subsidy. After the central government subsidy of Rs.78,000 (for systems of 3kW and above), your net cost comes down to approximately Rs.1,07,000-Rs.1,37,000. It generates around 12-15 units/day and is ideal for a 2-3 BHK home with moderate appliance usage.
Total cost of ownership for a 5kW system over 25 years: • Upfront cost: Rs.2-Rs.2.5 lakh (installed) • Annual maintenance: Rs.3,000-Rs.8,000 • Inverter replacement (year 10-12): Rs.15,000-Rs.30,000 • Total 25-year savings on electricity: Rs.8-Rs.15 lakh (depending on tariff hikes) Tip: Net ROI over 25 years can exceed 400% for most grid-connected rooftop systems in India.

Myth
Solar doesn't work during the monsoon
Fact
Systems still generate 60-70% during rainy months. Panels work on daylight, not just direct sun.
