A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity -generating solar panels mounted on the rooftop of a residential or commercial building or.
How do solar PV systems work on a flat roof?
Solar PV systems for flat roofs can be divided into two types: Flat roof mounted solar PV systems can be mounted on the roof structure via fixings which penetrate the waterproofing. The PV array is installed onto a rail system with hard point fixings into the structure, through the waterproofing layer.
What is a solar roof system?
The system is made up of individual panels mounted onto the roof which sit on top of your existing tiles or other roof finish. This solar roofing system is proven and widely available, but the main downside is the aesthetics. With an on-roof system, the panels are clearly added on as an afterthought and are not integrated into your home.

Can a solar PV system be placed on a roof?
Depending on your energy requirements, sustainability objectives, and budget, a solar PV system can be placed anywhere, including on the ground or even on pitched walls. However, if the circumstances are correct, a roof is a good choice for siting solar PV as it can make use of an otherwise underutilized space.
Flat roofs are a particularly useful site for solar PV. However, it is important to be aware that even ballasted systems involve some penetrations and therefore it is wise to ensure the system is designed, installed and maintained correctly to avoid invalidating your roofing warranty.
However, generally assessing your existing roof system and making necessary modifications, tends to be an effective way of strengthening a roof structure to accommodate a PV system if done properly. By reinforcing the current structural elements, you can significantly increase the capacity of your roof for solar installations.
