This is one of the most searched solar questions in Kerala — and one of the most underserved by existing content. If you live in an apartment or are part of a residents association, here is the honest picture.
Can an Individual Flat Owner Go Solar?
Yes — if you have exclusive access to a portion of the rooftop, you can install a rooftop solar system under your own KSEB consumer number and claim the full PM Surya Ghar subsidy. The key requirements are that the installation is registered under your electricity connection and the roof space is clearly attributed to your unit. In practice, this works best in low-rise apartment buildings where individual flats have dedicated terraces or roof sections.
What About Common Area Solar for a Housing Society?
A registered housing society or apartment association can install a solar system on the common roof and use the generated power to offset electricity consumed in common areas — lobby lights, lifts, water pumps, security systems, and exterior lighting. This is one of the fastest-growing applications of solar in urban Kerala.
A 20-flat apartment complex in Kochi spending ₹8,000/month on common area electricity installed a 5 kW system on the shared rooftop. Their common electricity bill dropped to under ₹1,200/month — a saving of over ₹80,000 annually.
Key Challenges for Apartment Solar
- Collective decision-making: All residents or the managing committee must agree to the installation. A general body resolution is typically required.
- Shared roof rights: The roof must be clearly owned or managed by the association, not disputed between flat owners.
- Structural assessment: High-rise buildings require a structural engineer's certification that the roof can bear the panel load.
- Individual subsidy: The PM Surya Ghar subsidy is available only to individual residential consumers, not to housing associations.
What Is the Best Approach?
For individual flat owners in low-rise buildings — apply independently through the PM Surya Ghar portal with an empanelled vendor. For housing societies — engage Rayenna for a site assessment. We will evaluate roof suitability, generate a savings projection, and support the committee with all documentation and approvals.
Apartment solar is absolutely viable in Kerala. The regulations support it. What it needs is the right guidance from the start.
