Apartment buildings in Kollam can install solar for common areas (lifts, pumps, lights) and claim ₹18,000 per kW under PM Surya Ghar through the RWA or Group Housing Society, up to 500 kW. Individual flats generally need the association's permission to use the terrace.
Option 1: Common-area solar (best fit)
Lifts, water pumps, corridor lights and parking lighting run all day, so a 5–20 kW system offsets the association's electricity bill. Savings fund maintenance and reduce service charges for every flat.
Option 2: Individual terrace slots
With the association's written consent, owners may be allotted terrace space for individual systems connected to their own meters. Needs clear terrace allocation, structural safety and agreements — complexity is higher.
Option 3: Group / virtual net metering
Rules allow shared generation to be credited across multiple meters in some regimes. Availability depends on KSEB / KSERC implementation — confirm before planning.
Approval checklist
- General body resolution approving solar
- Structural certificate for the terrace
- Single-line diagram and shadow analysis
- KSEB feasibility for the common-area connection
- Registered vendor and written AMC
