On-grid solar system in Kerala — the lowest-cost, fastest-payback choice
On-grid rooftop solar exports surplus power to KSEB during the day, draws from the grid at night, and zeroes out your bill via net metering. No batteries means lower upfront cost, longer hardware life, and the fastest payback of any solar configuration.

How on-grid solar works
Panels generate DC → string inverter converts to AC → power runs your loads first → surplus flows through the bi-directional KSEB meter to the grid. At night the meter spins forward again. KSEB nets your import and export monthly and settles surplus annually at the APPC rate.
Best fit for…
Homes and businesses with stable KSEB supply, daytime load (fridge, fans, ACs, pumps, office equipment), no critical need for power-cut backup. If outage backup matters, see hybrid solar.
What we install
Tier-1 panels (Waaree, Vikram, Adani, Premier), branded string inverters (Growatt, Solis, Sungrow, Deye), galvanised mounting structure, full DC/AC protection, KSEB net-meter commissioning, PM Surya Ghar subsidy filing.
Frequently asked questions
+What is an on-grid solar system?
An on-grid (grid-tied) solar system is connected to the KSEB electricity grid via a bi-directional net meter. It generates power during the day, runs your loads in real-time, and exports the surplus to KSEB for credit. There is no battery — at night you draw from the grid as usual.
+Why is on-grid the most popular choice in Kerala?
Lowest cost per kW, fastest payback (3–5 years), highest efficiency (no battery losses), eligible for the full PM Surya Ghar subsidy and KSEB net metering. 95% of Kerala residential solar is on-grid.
+Does on-grid work during power cuts?
No — on-grid inverters automatically shut down during grid outages for safety (anti-islanding). If outage backup is critical, choose a hybrid system with battery.
+Subsidy on on-grid systems?
Yes — full PM Surya Ghar subsidy up to ₹78,000 for residential on-grid installations in Kerala.
