The recast slab
Concrete that replaced the old roof is the only place we draw a row.
Older bungalows off the High Road
Solar panels for your home in Nungambakkam.
On these houses the roof can look flat and still not be concrete. The old part is a Madras terrace: brick on joists. Modules go only where that roof was later recast as a slab. The brick roof is not drilled. The visit from Madipakkam is free.
Flat is not the same as concrete
The recast slab, not the brick roof.
We do not anchor rails into the Madras terrace. Where a later concrete slab sits beside it, we mark only that slab, leave the tank and a walkway, and see whether that area matches the daytime bill. A house that is already all concrete is an ordinary survey. Pointing at the old brick roof from the street does not put it into the count.
Mangalore tiles over the rear rooms are the Selaiyur case. An old sheet over the rooms is the Siruseri case. An open courtyard in the middle is the Mylapore case. A tree in the same compound is the R.A. Puram case. Avenue shade that moves through the day is the Besant Nagar case. A lane side shaded by a taller block across the street is the T. Nagar case. A flat cannot take the common roof of a large block. That is the Sholinganallur case. City-wide module choice is on panels for a Chennai home.

The brick roof
The Madras terrace stays undrilled. A flat look from the street is not a slab.
03
Tank and walkway
On the concrete, the tank stays and a path stays. The row uses what remains.
04
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 bungalows off the High Road are the usual fit. A flat cannot claim the common roof of a large block. If the rear rooms are still under tiles, that roof is left alone the way the Selaiyur page describes, before the brick terrace is marked.
How the row is fixed once the recast slab is clear is on solar panel installation. Modules you already hold are labour from ₹3,000 per kW, materials excluded, on installation services. The Nungambakkam figure is on solar panels and prices in Nungambakkam. How the crew sets the row is on solar panels and installation in Nungambakkam. The subsidy gap is on panel and price. NDCR against DCR is in that guide before an import is confirmed.
Show the brick roof and the concrete
The old roof, then the row.
Do you visit Nungambakkam from Madipakkam?
Yes. The roof visit is free. A recent bill and a photo of the old brick roof and any recast concrete, if both exist, are enough to start. No modules are ordered that day.
Can modules go on the old Madras terrace?
No. That roof is brick on joists. Rails go only on concrete that was recast later.
The roof is already all concrete. Does the same limit apply?
No. A wholly concrete terrace 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 of the brick roof and the concrete.
A free visit from Madipakkam. We mark the recast slab, leave the old terrace undrilled, and note whether the plant should be DCR.
