Flat reinforced concrete roofs dominate Raipur, and they are the easiest surface for solar on flat roof in Raipur: they allow ideal tilt, spacing and access. The details of frames, drainage and waterproofing decide whether the plant is trouble-free.
Quick answer: use galvanised frames at 15 to 20 degrees, space rows against winter shade, seal every foundation and keep drains clear.
| Choice | Effect |
|---|---|
| Tilt 10 degrees | Closer rows, slightly lower yearly output |
| Tilt 20 degrees | Better output, more row spacing |
| East-west layout | More panels per roof, flatter daily curve |
| Raised frames | Usable roof space below |

When panels tilt, the back of one row can shade the front of the next in low winter sun. Installers calculate spacing from tilt and latitude. A lower tilt means closer rows but slightly lower yearly output, and a higher tilt means more output but wider spacing. For most Raipur terraces, 15 to 20 degrees is a good compromise.
| Tilt | Row spacing | Comment |
|---|---|---|
| 10 degrees | Close | More panels per roof |
| 15 degrees | Moderate | Common choice |
| 20 degrees | Wider | Slightly better yearly output |
| Flush on roof | None | Not recommended on flat roofs |
Roof repairs, extra rooms and new water tanks will come. A good layout leaves room for them. Ask the installer how the array can be dismantled for roof repairs and what it costs. Read roof waterproofing before solar to avoid trouble.
