The govt pays you to go solar.
Under PM Surya Ghar, the centre sends up to ₹78,000 to your bank once your net meter is live — and net metering can pull the bill close to zero.

We install
A clean, certified install by our team. KSEB inspects and fits your net meter.
You get paid
Savings start from day one and the subsidy reaches your bank within 30–60 days.
From your bill to a live meter.
Going solar in Kerala means satisfying two separate authorities: KSEB, who must approve the connection and fit the meter, and the central PM Surya Ghar scheme, which pays the subsidy. They run on different portals and different paperwork. This is the whole sequence, and who does what at each stage.
Your bill, and a look at the roof
DeltaIt starts with a recent KSEB bill. It carries your consumer number, your connection type and your consumption history, which between them determine what size system makes sense and whether you are eligible for the residential subsidy at all. A site visit then settles what the bill cannot: usable area, shading through the day, roof condition and where the inverter and cabling will run.
A written quote, before anything is ordered
DeltaYou get the system size, the specific panels and inverter, the expected annual generation, the price, the subsidy you should receive and the warranty terms — in writing. Nothing is ordered and nothing is charged until you have that and have agreed to it.
Registration on the national portal
You, with usThe PM Surya Ghar application is made against your consumer number and your bank account, so this is the step that has to be yours. We sit with you through it. The bank account you register is where the subsidy will land, so it needs to be right and it needs to match the connection holder.
The KSEB application
DeltaAll grid-interactive rooftop applications go through the Solar Rooftop Portal – Kerala. We prepare and file the connectivity application and the technical documentation for the proposed system, and handle the correspondence from there.
Approval, then installation
DeltaInstallation follows approval, not the other way round — a system commissioned early is a problem to unwind rather than a head start. The rooftop work itself is typically a few days for a domestic system: mounting structure, panels, inverter, earthing and protection, then the connection into your board.
Inspection and the net meter
KSEBKSEB inspects the installation against the safety and technical requirements, and on clearing it replaces your meter with a bidirectional net meter and fits the renewable energy meter. Both are installed and sealed by KSEB. From the moment they are live, your generation starts counting against your bill.
The subsidy reaches your account
Central governmentWith commissioning confirmed, the central financial assistance is credited directly to the bank account on your PM Surya Ghar application — to you, not to us. Delta never receives it on your behalf, which is why the quote you signed is the amount you pay.
End to end, consultation to a live net meter typically runs 4–8 weeks. Most of that is not construction — the rooftop work is a matter of days — but approval and inspection, which run to the utility's schedule rather than ours.

PM Surya Ghar questions.
What people ask once they realise the subsidy is not a flat percentage.
It is not a flat percentage. PM Surya Ghar pays ₹30,000 for each of the first two kilowatts and ₹18,000 for the third — so 1 kW draws ₹30,000, 2 kW draws ₹60,000, and 3 kW draws ₹78,000. Capacity beyond 3 kW earns no additional central subsidy, which is why 3 kW is the size most Kerala homes settle on.
