The parapet
We trace the actual wall, not a rectangle imagined from the street. Steps and cut corners come off the drawing.
Keelkattalai houses beside the eri
Solar panels for your home in Keelkattalai.
Plots beside the lake are often not a clean rectangle, and the parapet follows that shape. Modules go in the clear rectangle inside it. The odd corners stay for the tank and a walkway. If the lane holds water when the eri rises, the install day waits. The visit from Madipakkam is free.
Shape before wattage
Fit the rectangle. Leave the corners.
Older houses around Keelkattalai eri, and some of the newer ones on the same irregular plots, do not give a brochure roof. One side steps in for a neighbour's wall. Another corner is cut by the stair room. Chasing that crooked edge with extra modules wastes glass and blocks the tank. We measure the largest clear rectangle, put the row there, and stop.
The lake changes the calendar more than the drawing. Some lanes hold water after a heavy rain. A design can be finished then. A lorry cannot. We book delivery for a day the street is passable. City-wide module choice is on panels for a Chennai home. Whether the slab is the last floor is the Medavakkam question. Wind off open wetland is the Pallikaranai case. Here the limits are the shape of the plot and the day a vehicle can arrive.

The clear block
Modules sit in the largest straight block that remains. We do not trim glass to follow a crooked edge.
03
The lane
If the street beside the eri floods, that fact goes on the schedule. The install waits for a passable day.

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 roof you can draw as a rectangle.
Independent houses around the eri are the usual fit, including those whose plot is not square. A flat proceeds only after the association has allowed that household to use the terrace, in writing. A balcony toward the water is not a mounting place.
How the row is fixed inside that rectangle is on solar panel installation. Modules you already hold are labour, quoted on installation services. The Keelkattalai figure is on solar panels and prices in Keelkattalai. How the crew sets the row is on solar panels and installation in Keelkattalai. The subsidy gap is on panel and price. NDCR against DCR is in that guide before an import is confirmed.
Before the lorry is booked
Shape, the lane, then the subsidy.
Do you visit Keelkattalai from Madipakkam?
Yes. The roof visit is free. A recent bill and a terrace photo are enough to start. No modules are ordered that day.
The parapet is not a rectangle. Can modules still fit?
Yes, inside the largest clear rectangle. The odd corners stay open for the tank and a walkway. We do not cut modules to follow the crooked edge.
Our lane floods when the eri rises. Does that stop the plant?
It stops the delivery day, not the design. We book the install when a vehicle can reach the house.
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 Keelkattalai parapet.
And say if the lane floods. A free visit from Madipakkam. We mark the clear rectangle and whether the plant should be DCR.
