Solar panels are a popular renewable energy solution that offers sustainable electricity and decreased dependence on more traditional energy sources, but are they suitable for flat roofs? Let’s find out.
Are solar panels suitable for flat roofs?
The simple answer is that you can have solar panels on flat roofs; however, there are some additional requirements and considerations that you need to think about to ensure they last as long as possible and work effectively.
Experts in solar panel installation Bristol and beyond will explain that solar panels used for flat roofs are no different to those for pitched roofs. Specialists such as https://redbridgeandsons.co.uk/solar-pv-panels/solar-panel-installers-bristol know that the panels should not be installed flat, however, as they might not absorb enough sunlight and could even cause water damage.
Instead, solar panels on flat roofs need a framing system that tilts them towards the sun. This maximises sun exposure and allows for self-cleaning when it rains. It also prevents water from pooling.
Framing options
There are generally two choices when it comes to framing systems for flat roofs, the first of which is panels that can be fixed by drilling into your roof and using stabilising brackets for the frame. Experts will take care to ensure the roof remains watertight.
Alternatively, weight can be added to the frame structure. The frame is placed into heavy slabs, concrete ballasts, or special tubs weighed down with slabs.
Pros and cons
There are many benefits to solar panels for flat roofs, ranging from financial savings to environmental impact. You can find out more about these on the Energy.Gov website.
Correct installation is vital to avoid potential disadvantages, such as warranty concerns if water is allowed to cause degradation of the panels.
