The sheet
Rails are not screwed through the old sheet. That slope is not spare area.

The crew sets the rails on the concrete and leaves the sheet roof. If you already own the panels and inverter, fitting starts at ₹3,000 per kW. A complete plant is drawn after a free visit from Madipakkam.

What the old rooms are under
The old rooms keep their sheet. Rails are not screwed through it, and that slope is not spare area. Where a later concrete terrace sits beside or above that roof, we mark only the slab, leave the tank and a walkway, and see whether the open area matches the daytime bill. A house that is already all concrete is an ordinary survey. An office block inside the park is a different project. The roof itself is on panels for a Siruseri home. Where a panel is fixed is on solar panel installation in Siruseri.
Labour from ₹3,000 per kW covers civil work, mounting, wiring, testing, and commissioning when the modules and inverter are already yours. Cables and structure steel stay outside that rate. The scope is on installation services.

Rails are not screwed through the old sheet. That slope is not spare area.
Only the concrete beside or above the sheet is counted. The tank and a walkway stay.
An office block inside the park is a different project. This survey is a house terrace.
Eligible homeowners can receive up to ₹78,000 with DCR modules and an approved file. Amount and approval follow current scheme rules. The row is still drawn only where the roof stays clear.
How to read the job
Ask whether the rails stayed on the concrete and the sheet was left alone. Labour from ₹3,000 per kW is fitting only, when the modules and inverter are already yours. A complete plant is drawn after the visit. Independent houses in the old lanes, and villas with a terrace in the household name, are the usual fit. A flat cannot claim the common roof of a large community. A plant on a SIPCOT office block is not this survey.
The figure is on solar panels and prices in Siruseri. How any Chennai quote should be lined up is on panel and price. A car porch under the upper slab is the Kelambakkam installation.
