The finished slab
The concrete between the columns is the only place we draw a row.
Columns already on the terrace
Solar panels for your home in Kolathur.
On many of these houses the next floor is started and not cast. The columns already stand on the terrace. They stay. Rails are not fixed to them, and they are not used as the frame. The visit from Madipakkam is free.
A floor that is not cast yet
Between the columns, not on them.
We draw the row only on the finished slab between those columns. If the owner says the next slab is still coming, we do not start, because this is not the final roof. If there are no columns, and the only question is whether another floor might come later, that is a different survey. Columns on the next plot, still rising, are a different survey too. A terrace with no columns, and a roof the owner calls final, is an ordinary survey. The tank stays. A walkway stays.
A house built in stages, where the terrace only looks finished, is the Medavakkam case. Columns still going up on the next plot are the OMR case. A parapet that is still a low course of brick is the Perungalathur case. Two concrete slabs at two heights are the Chromepet case. A later room that leaves only an L is the West Mambalam case. A flat cannot take a common roof. That is the Sholinganallur case. City-wide module choice is on panels for a Chennai home.

Four checks around the columns.

The columns
They stay. Rails are not fixed to them, and they are not the frame.
03
The next floor
If that slab is still coming, we do not start. This roof is not final.

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 are the usual fit, including a house whose next floor is only columns so far. A flat cannot claim the building's roof. If there are no columns and the owner calls the roof final, the survey is ordinary unless another limit on these pages applies.
How the row is fixed once the columns are left clear is on solar panel installation. Modules you already hold are labour from ₹3,000 per kW, materials excluded, on installation services. The Kolathur figure is on solar panels and prices in Kolathur. How the crew sets the row is on solar panels and installation in Kolathur. The subsidy gap is on panel and price. NDCR against DCR is in that guide before an import is confirmed.
Show the columns, if they already stand
The columns, then the slab.
Do you visit Kolathur from Madipakkam?
Yes. The roof visit is free. A recent bill and a photo that shows the columns, if they already stand on the terrace, are enough to start. No modules are ordered that day.
Can the rails be fixed to those columns?
No. The columns stay as they are. The row sits on the finished slab between them.
There are no columns. Does the same limit apply?
No. A terrace with no columns, which the owner calls final, 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 columns, if they already stand.
A free visit from Madipakkam. We leave those columns unused, and note whether the plant should be DCR.
