How Do Flat Roof Solar Panels Work on a Flat Roof?

How Do Flat Roof Solar Panels Work on a Flat Roof? 

Solar panels can work very well on a flat roof. Whilst flat roof solar systems are more commonly found on commercial buildings, they can certainly be fitted to domestic properties. 

 The array will use the same type of solar panel as a traditional system but considerations need to be made to ensure it is able to self-clean in the rain and avoid damage from strong winds. 

 The pitch of the system will also be taken into account by the installer to ensure it can capture the optimum amount of energy from the sun.

What are the benefits of having solar panels on a flat roof?

Although there are specific considerations to be made with flat roof installations there are also plenty of benefits:

● Flat roofs provide easy access and plenty of room for installation and maintenance.
● This type of system is rarely visible from the street.
● You can receive the government’s Feed-in Tariff if your system is installed by an MCS certified company.

What considerations need to be made for wind and flat roof solar panels?

High winds are a potential risk to flat roof solar mounting, however there are different options to counter this. There are two common methods used to protect a system; fixing panels to the structure or adding weight to them. Using weight involves fitting ballast frames and heavy slabs to the roof, which solar panels are then attached to. Fixing the panels to the structure involves penetrating the roof itself and securing a support structure and brackets which the solar panels themselves are then attached to.

Can I also have flat roof mounted solar thermal systems?

Yes, solar thermal systems will be attached in the same way as a PV system for a flat roof. They will also work in the same way as any other traditional solar thermal system to generate heated water for your home.

It’s important to hire a qualified and experienced solar installer to ensure your system is fitted correctly and so that you can benefit from the Feed-in Tariff. Solar Guide offers quotes from a range of MCS accredited companies with experience in fitting flat roof solar panel systems.
