Solar Subsidy in Kerala: What Residential Customers Should Know
Subsidy can improve home solar economics, but only when the process, component compliance and expectations are handled correctly.
By Solwiz Energy Team. Reviewed as organizational guidance by Solwiz Energy.
The current amount for individual households
Under current PM Surya Ghar guidance, an eligible residential consumer may receive ₹30,000 per kW for the first 2 kW and ₹18,000 for the next 1 kW. That gives ₹30,000 for 1 kW, ₹60,000 for 2 kW and a maximum of ₹78,000 for an individual-household system of 3 kW or more.
These figures were checked against MNRE material on 21 September 2026. Rules can change, so verify the live PM Surya Ghar portal and MNRE rooftop solar programme page before committing. The shorter solar subsidy Kerala page summarises the service.
Who this assistance is for
The individual-household amount above is for eligible residential consumers following the applicable process. A commercial connection, a battery purchased separately, or an installation completed outside the required route should not be represented as automatically eligible. Group housing and resident welfare association provisions have separate rules and should be checked directly against current guidance.
The application and approval sequence
- Confirm that the KSEB consumer details, mobile number and email are current.
- Register through the applicable national and Kerala solar portal route.
- Submit the required application details and complete technical-feasibility steps.
- Select the applicable registered vendor route and agree a written system scope.
- Install compliant equipment only after the required pre-installation steps are complete.
- Submit project-completion evidence and supporting records.
- Complete KSEB inspection, agreement, metering and commissioning steps.
- Track central-assistance processing through the official portal.
The KSEB Solar Rooftop Portal describes itself as the state's single-window route for grid-connected rooftop applications. Exact screens and document requirements can change, so use the portal's current instructions rather than an old screenshot or checklist.
Documents to prepare
Start with the latest electricity bill and consumer number, registered mobile and email details, required identity and bank information, roof photographs and property/site information. The portal, KSEB or other authority may request additional records for the consumer category and system.
Who is responsible for what
The customer provides accurate personal, bank, property and electricity-account information and completes required declarations. Solwiz can review the bill and roof, explain the agreed scope, support document readiness, install the system and organise handover records. KSEB, MNRE and other authorities control technical feasibility, inspection, commissioning, eligibility and release.
No installer can guarantee approval, the release date or an unchanged scheme amount.
Size the system for the home, not the headline
Do not choose a larger system only because the assistance rises up to 3 kW. Capacity should follow electricity use, sanctioned load or contract limits, usable unshaded roof, export treatment and budget. The system may be larger than 3 kW where justified, but the individual-household central assistance described above is capped at ₹78,000 under current guidance.
Subsidy, finance and battery backup are different
Subsidy is conditional assistance after the applicable process. Finance changes how the customer pays. Battery storage changes equipment cost and outage capability. A subsidised on-grid system can still shut down during a power cut, and battery cost is not automatically covered by the residential assistance amount.
Common reasons to pause and verify
- The consumer name or registered contact details do not match current records.
- Installation is proposed before required feasibility or portal steps.
- The quote does not identify compliant equipment and substitutions.
- Subsidy is shown as guaranteed or already deducted without explaining the payment route.
- Roof shade, structure or sanctioned load has not been checked.
- Handover and completion documents are missing.
Use the official portals for the rule, and the written quotation for the installer's scope. That distinction prevents most subsidy misunderstandings.
FAQs
Is solar subsidy available for commercial customers?
Residential subsidy is not meant for commercial projects. Commercial solar should be evaluated through ROI, finance, depreciation and operating cost reduction.
Can Solwiz guarantee subsidy approval?
No installer should guarantee final subsidy approval. Solwiz can guide the process, but final approval depends on scheme and utility rules.
