Solar panels for your home in Taramani.

A wide office block can cover the same half of a terrace every afternoon. The other half may still be worth using. If you rent, the electricity bill is not permission. The owner, or the association when the roof is shared, has to allow it in writing. The visit is from Madipakkam and is free.

Beside the IT parks, including the TIDEL Park side, the neighbour is often a broad office building rather than a house. Its shadow arrives at nearly the same time each afternoon and leaves one side clear. Modules go only on that side. Covering the shaded half does not add useful output. It only adds glass that sits dark.

Many of these flats are rented to people who work nearby. The name on the bill is often not the name that can allow the roof. We wait for the owner. If the terrace is common, we wait for the association. On the older house streets away from the parks, the owner usually decides alone. City-wide module choice is on panels for a Chennai home. A telecom mast on the terrace is the Perungudi case. Here the limit is an office block, and who is allowed to say yes.

We mark the side the office block covers, and the hours it stays covered. A noon photo is not that record.

A full plant for a Chennai home is described on the solar installation page. The visit is free, and nothing is ordered until you ask. The desk is open monday to saturday, 9:00 am – 7:00 pm.
