6 FAQs about [Construction steps of photovoltaic panels on flat roofs of buildings]

Can a flat roof solar system be installed on a domestic property?

Whilst flat roof solar systems are more commonly used on commercial buildings, they can certainly be fitted onto domestic properties too. Read on to find out more about flat roof solar, and how in many cases it is actually better than normal on-roof solar! How do Solar Panel Systems on a Flat Roof Work?

Can solar panels be mounted on a flat roof?

This means there are a two different mounting systems to help ensure you get the best out of your solar panels on a flat roof. A mounting system is critical for solar panels on a flat roof, as by using a framing system, the panels can be tilted toward the sun, enhancing their efficiency.

How do I install solar panels on a flat roof?

There are a few crucial steps to follow when installing solar panels on a flat roof: To start the process, an engineer will carry out a structural survey to check if your roof is suitable for handling the solar panels' weight and the ballast used to secure them.

How do you fix a PV system to a flat roof?

There are two fundamental options for fixing a PV system to a flat roof, ballasted or mechanical. A ballasted system adds additional weight to anchor the array to the roof whereas mechanical installations cover two key methods, either they are fixed to the deck penetrating the roof covering or they do not and leave the waterproofing system intact.

How much does a solar panel weigh on a flat roof?

As mentioned earlier, solar panels on a flat roof need a heavy ballasted mounting system to stay secure in high winds. And that ballast can make a solar panel up to five times heavier than a typical non-ballasted panel. A ballasted solar panel can weigh around 100kg, whereas a non-ballasted solar panel is only about 20kg.

Can a PV system be integrated into a flat roof?

In some cases, PV systems can be integrated directly into flat roofs (Figure 25), although this is not common because the efficiency of PV modules is reduced because the optimum angle relative to the sun is not achieved.
