Where the service drop lands on the stair-head wall in the middle, the air path to that wall stays clear. Modules are not laid under it. The hook is not moved. The visit from Madipakkam is free.
The service drop lands on the stair-head wall. The air path to that wall stays clear. Modules are not laid under it. The hook is not moved. A house where the drop stays off that wall is an ordinary survey.
A cable that only crosses above the slab is the Kottivakkam case. A cable along the front parapet is the Gopalapuram case. The street line along the whole front parapet is the Tondiarpet case. A flyover deck already above the parapet is the Porur case. A narrow plot that takes one row is the Adambakkam case. A flat that cannot take a common roof is the Sholinganallur case. City-wide module choice is on panels for a Chennai home.
We mark the stair-head wall before any row is drawn.
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.
