Your slab
The concrete on your side of the shared wall is the only place we draw a row.
Old lanes with a low shared wall
Solar panels for your home in Triplicane.
In these lanes the next house often shares the wall, and the wall on the terrace is only a low course of brick. The two slabs look like one roof. The row stays on your side. Rails do not cross that wall. The visit from Madipakkam is free.
Where your slab ends
Your side of the wall, only.
The frame stops at that wall. We do not step it onto the next terrace to catch more sun, and we do not ask the neighbour to sign a roof that is not theirs. The tank stays. A walkway stays. What remains is matched to the daytime bill. A terrace with its own full-height parapet, and no low shared wall, is an ordinary survey.
A party wall between row villas, where each slab is already a separate roof, is the Padur case. An open courtyard in the middle of the house is the Mylapore case. A neighbour's rain pipe on the slab is the Royapettah case. An old brick roof that only looks flat is the Nungambakkam case. A room already standing on the terrace is the Injambakkam case. A rented room cannot take the building's roof. That is the Sholinganallur case. City-wide module choice is on panels for a Chennai home.

The low wall
Rails stop there. The next terrace is not spare area, even when the wall is only a few courses high.
03
Tank and walkway
Both stay on your slab. The row uses what remains after they are marked.

DCR
Central assistance needs cells and modules made in India. Eligible homes can receive up to ₹78,000. The amount follows the scheme on the day you apply.
Who it suits
A house with its own terrace.
Independent houses in the old lanes are the usual fit. A rented room and a flat cannot claim the building's roof. If the parapet is already full height and the next roof is clearly separate, the survey is ordinary unless another limit on these pages applies.
How the row is fixed once your side is clear is on solar panel installation. Modules you already hold are labour from ₹3,000 per kW, materials excluded, on installation services. The Triplicane figure is on solar panels and prices in Triplicane. How the crew sets the row is on solar panels and installation in Triplicane. The subsidy gap is on panel and price. NDCR against DCR is in that guide before an import is confirmed.
Show the shared wall, if there is one
Your slab, then the row.
Do you visit Triplicane from Madipakkam?
Yes. The roof visit is free. A recent bill and a photo that shows the shared wall, if there is one, are enough to start. No modules are ordered that day.
Can the row cross a low wall onto the next terrace?
No. Rails stop on your side of that wall. The neighbour is not asked to sign a roof that is not theirs.
The parapet is already full height. Does the same limit apply?
No. A terrace with its own full-height parapet, and no low shared wall, is a normal survey. The tank stays, and a walkway stays.
Do subsidy plants need DCR modules?
Yes. Cells and modules must be made in India. Eligible homes can receive up to ₹78,000, subject to the scheme on the day you apply. NDCR is only if that assistance has already been given up.
Send a photo that shows the shared wall, if there is one.
A free visit from Madipakkam. We keep the row on your side of that wall, and note whether the plant should be DCR.
