Rooftop PV systems provide a clean and increasingly affordable option for building owners and occupants to produce their electricity. For this reason, the Rooftop Solar installation market is growing exponentially on a global scale. This trend is expected to continue going forward in the coming years, as building designers and engineers are considering solar rooftop installations more frequently on new buildings.

With several incidents encountered by solar installers globally, we felt putting something out there, brief, and concise; hoping this knowledge transfer will improve the solar space.

Roofs are the resting place of most residential solar systems. Most roofs were not planned to have these multiple big solar panels mounted on them. For example, a typical 400watts panel would have a dead weight of 20kg, not taking into consideration potential live weights. So what happens when you have 20 pieces of these guys sitting on your roof? Well, it depends.
