How Do I Know If My Roof is Suitable for a Solar Rooftop System?
Do you know the most important factors to analyze before you choose to install a solar rooftop system? Did you ever think about going solar and don’t know if it is possible?
Every solar system needs unobstructed access to sunlight. Therefore, one of the most important criteria for your roof is that it should be free from any shading. Shading could be caused by adjacent buildings, trees, lighting and electricity poles, or structures such as ledges or chimneys built on the roof itself.
Another important factor is the orientation of the solar modules, which refers to their positioning with respect to the sun’s path across the sky. On a flat roof, you have the flexibility of orienting modules any which way you want (in India, they are best oriented towards the South).
If your roof is not flat, the inclination of it matters. You may only be able to use sections of the roof that are angled in the right direction (ideally South).
A third important aspect to consider is the structural condition of your roof. Is it solidly built? Can it take the load of a PV system? Will the rooftop (or the building, for that matter) last long enough for your solar system to pay off (say 5 years)?
Figure these basic parameters out and then, if it works, don’t hesitate to go solar!
