Get up to ₹78,000 in solar subsidy
Residential rooftops on the coast qualify for central and state support. Your estimate already factors this in.
- PM Surya Ghar: Muft Bijli Yojana — Central subsidy of ₹30,000/kW for the first 2 kW and ₹18,000 for the third — capped at ₹78,000.
- Net metering with MESCOM — Export surplus units to the grid and get billed only for your net consumption.
- Business depreciation benefit — Commercial & industrial systems can claim accelerated depreciation instead of the subsidy.
- No-cost roadmap — We size the system, estimate cost after subsidy, and point you to certified installers.

It uses coastal-Karnataka generation averages, current MESCOM tariffs, real panel wattage and live PM Surya Ghar subsidy rules. Treat it as a solid starting point — actual installer quotes vary with your roof, brands and dealer.
Residential rooftops get ₹30,000/kW for the first 2 kW and ₹18,000 for the third under PM Surya Ghar — capped at ₹78,000. Your estimate already deducts this from the system cost.
It depends on your monthly consumption. A typical Karavali home with a ₹2,500 bill needs around 3 kW. Enter your bill above and the calculator sizes it for you.
Individual flats usually cannot, but housing societies can install a shared rooftop system on common area supply. Independent homes and rowhouses are ideal.
A meter that records both the units you draw from the grid and the surplus your panels export. You are billed only on the net — so daytime generation offsets night-time usage. Approval comes through your local MESCOM section office.
Quality panels come with 25-year performance warranties and keep generating beyond that, with only gradual efficiency loss. Inverters typically need replacing once in that period.
Rooftop solar in Udupi, Mangaluru & coastal Karnataka
The Karavali coast gets strong, consistent sunshine for most of the year, and even through the monsoon a well-sized rooftop system keeps generating. That makes districts like Udupi and Dakshina Kannada some of the best places in Karnataka for home solar. With MESCOM tariffs climbing, a rooftop system that offsets your daytime consumption pays for itself in just a few years and then generates power almost for free for the next two decades.
How much can you save?
A typical coastal home with a ₹2,500–₹3,000 monthly electricity bill needs roughly a 3 kW system. After the PM Surya Ghar subsidy, the net cost usually lands within a few years of payback, after which the same system keeps trimming your bill for 25 years or more. Businesses and farms can size larger systems and, while they don't get the residential subsidy, they can claim accelerated depreciation and still see strong returns. Use the calculator above to size your own system and see the numbers for your exact bill.
PM Surya Ghar: Muft Bijli Yojana
Under the central PM Surya Ghar scheme, residential rooftop systems qualify for a subsidy of ₹30,000 per kW for the first two kilowatts and ₹18,000 for the third, capped at ₹78,000. Combined with net metering — where surplus units you export are credited against what you draw at night — this dramatically shortens payback. The subsidy is applied after installation and approval through your local MESCOM section office.
Why solar makes sense on the coast
Beyond the savings, rooftop solar shields you from rising grid tariffs, cuts your household's carbon footprint by several tonnes of CO₂ every year, and adds value to your property. For coastal Karnataka — where power reliability and clean energy both matter — it's one of the most practical investments a home or business can make. Karavali.net is a community platform, not a commercial installer: our goal is to give you honest, localised numbers and then connect you with verified installers so you can go solar with confidence.
