Get a load analysis for your roof done by a Civil Engineer, to ensure that your roof will withstand the additional ballast load (P V module mounting structure load) and the weight of the P V panels. Take 80% of available roof area when sizing your P V system. Ensure that no shadow falls on your roof between 9AM and 3 PM. Then just go ahead!

The 80% rule maybe a good heuristic but realistically, latitude (across India) would define the panel inclination & hence the PV system array. The EnerMark estimator carefully takes these into account. I would suggest to try the estimator by clicking enermark.com/businesscase for various locations.

A solar power system can be installed on virtually any roof surface; the most limiting factor is shade. Solar panels are usually installed parallel to the roof surface and require approximately 100 sq. ft. for every 1000 watts of DC array. South facing roofs offer the most annual production, while east and north will produce much less energy. However, west-facing roofs produce more power during "peak" times when power can be more expensive.

EnerMark suggests that customers with older roofs consider replacement prior to installing solar panels.
