Solar for apartments and housing associations in Kochi & Ernakulam

On an apartment block the roof is common property, so the first question is not technical. It is who decides.

Not as an individual flat, in almost all cases, because the roof is common property. A rooftop system in an apartment block is an owners association project: the association allocates the roof space, holds the arrangement, and decides how the output…

01

The roof is common property

So the decision sits with the association, not a single owner.

02

Common-area load is the usual target

Lifts, water pumps and lighting run during the day, which matches generation well.

03

Connection type matters

Whether the system offsets the association’s common-area connection or individual flat connections changes the design and the net-metering arrangement.

04

Roof clutter needs measuring

Apartment roofs carry tanks, lift machine rooms and antennae. Usable area is usually well below the building footprint.

The usual target

Common-area load, not individual flats

This is the single most frequent reason an apartment enquiry stalls, and it is better understood at the start than after a survey has been booked.

Questions a committee asks

Apartments, answered

Who has to approve it?

The association or the owners’ body, because the roof is common property. We are happy to present to a committee before anyone commits to anything.

Does the PM Surya Ghar subsidy apply?

It depends on the connection type the system is tied to. A residential connection can qualify; a commercial one does not. The survey establishes which you have.

Whose bill does it reduce?

Usually the common-area connection – lifts, pumps, corridor lighting – because that is a single connection the association already pays for.

What about roof clutter?

Tanks, lift machine rooms, dish antennas and vents all reduce usable area. On an apartment roof this is almost always the binding constraint.

Questions

Associations, answered

Generally no, because the roof belongs to all owners. The route is through the owners association allocating roof space.

Most commonly the common-area load - lifts, pumps and lighting - which runs during generating hours. Whether individual flats can be offset depends on how the connections are arranged.

The scheme is for residential rooftop consumers, and there are provisions relating to group housing common facilities. Eligibility depends on how the connection and the application are structured, so it should be checked for your specific block rather than assumed.

Talk to us before the association meeting. We can explain what the roof can carry and what the options are, so the meeting has real information in front of it.

Next step

We will present to your committee.

A free roof survey and a written proposal the association can circulate before deciding.
