Choosing the right solar panels is only part of the journey towards generating your own renewable energy. The way those panels are installed is just as important. The mounting system used affects everything from energy generation and roof protection to the appearance of your home and the lifespan of your solar PV system.
At SolarTherm UK, we’ve spent more than 16 years designing and installing bespoke solar PV systems across Essex, Kent, Suffolk, Hertfordshire and the wider South East and East Anglia. Every property is unique, so we never recommend a one size fits all solution. Instead, we carefully assess your roof, your home’s structure and your energy requirements before designing a system that will deliver reliable performance for decades.
Whether you’re considering flat roof solar panels, integrated solar panels, ground mounted solar or traditional on-roof panels, understanding the different mounting systems will help you make an informed decision.
What Is a Solar Panel Mounting System?
A mounting system is the framework that securely fixes solar panels to your roof or the ground. While it often goes unnoticed once the installation is complete, it plays one of the more important roles in the entire system.
A professionally designed mounting system ensures the panels remain secure during high winds and poor weather, positions them at the correct angle to maximise solar generation and protects the integrity of your roof. It also allows for adequate ventilation beneath the panels, helping maintain efficiency throughout the year.
Choosing quality mounting equipment and ensuring it is installed correctly is essential for the long term performance of your solar PV system.
Why the Mounting Method Matters
Many homeowners naturally focus on the panels themselves, but even the highest performing solar panels can fail to reach their potential if they are installed using an unsuitable mounting system.
The right installation method influences how much electricity your system produces, how well your roof is protected, how straightforward future maintenance will be and even how your finished installation looks from the street. A carefully designed mounting solution also helps ensure your system continues performing efficiently for 30 years or more.
At SolarTherm UK, every installation begins with a comprehensive site survey so we can recommend the mounting system that best suits your property rather than simply installing the same system on every home.
Traditional On-Roof Solar Panels
For most homes throughout the UK, an on-roof installation remains the most practical and cost-effective option.
With this method, aluminium rails are fixed securely to the roof structure beneath your existing roof tiles before the solar panels are attached above them. As the original roof covering remains in place, installation is generally quicker and less expensive than alternative methods.
On-roof systems also benefit from improved airflow behind the panels, helping them operate efficiently throughout the warmer months. They are suitable for most tiled, slate and concrete roofs, making them the most common choice for homeowners across Essex, Kent, Suffolk and Hertfordshire.
In-Roof Solar Panels
For homeowners looking for a more contemporary appearance, in-roof – or integrated – solar panels provide an attractive alternative.
Rather than sitting above the roof covering, these systems replace a section of roof tiles, allowing the panels to become part of the roof itself. The finished result is flush with the surrounding roofline, creating a much cleaner appearance than a traditional on-roof installation.
In-roof systems are particularly popular on new builds or when replacing an ageing roof, as both projects can often be completed together. Although installation costs are usually slightly higher, many homeowners feel the improved aesthetics justify the additional investment.
Flat Roof Solar Panels
A common misconception is that solar panels can only be installed on pitched roofs. In reality, flat roof solar panels are becoming increasingly popular across both residential and commercial properties.
As a flat roof does not naturally position panels towards the sun, specialist mounting frames are used to create the ideal angle for solar generation. These frames can either be secured using ballast weights or mechanically fixed to the roof structure, depending on the building’s design and structural requirements.
Every flat roof installation begins with detailed structural calculations to ensure the roof can safely support the system while complying with current building regulations. When correctly designed, flat roof systems can deliver outstanding performance and often provide greater flexibility when positioning panels for maximum sunlight exposure.
Ground Mounted Solar Panels
Not every property has a suitable roof, but that doesn’t mean solar energy isn’t an option. Ground mounted solar panels are installed on steel support frames anchored directly into the ground, making them ideal for larger gardens, rural homes or properties where roof shading limits generation.
One of the biggest advantages of ground mounted systems is flexibility. As they aren’t restricted by the shape or direction of your roof, they can often be positioned at the ideal angle and orientation to maximise electricity production throughout the year. They’re also easier to access for routine maintenance and cleaning, which can help maintain long term performance.
For homeowners with sufficient outdoor space, ground mounted systems can even accommodate larger solar arrays than would be possible on the roof alone.
Choosing the Right Mounting System
No two homes are identical, which is why selecting the right mounting system requires more than simply choosing between roof or ground installation.
Factors such as age and condition of your roof, the direction it faces, its pitch, available space and your long term plans for the property all influence which installation method is most appropriate. Planning considerations may also affect the final design, particularly for listed buildings or homes located within a conservation area.
This is why SolarTherm UK carries out a detailed property assessment and site survey before every installation. By understanding your home and your energy goals, we can recommend the solution that offers the best combination of performance, aesthetics and long term value.

Frequently Asked Questions
Both options have advantages. Traditional on-roof systems are generally more affordable and easier to install, while in roof solar panels offer a more streamlined appearance and are often preferred during roof replacement projects.
Yes. Modern flat roof solar panels are installed using angled mounting systems that position them for optimum sunlight exposure, allowing them to perform just as efficiently as many pitched roof installations.
If the appearance of your property is a priority, integrated solar panels provide a sleek, modern finish while still delivering excellent energy generation.
Absolutely. Ground mounted solar panels are an excellent alternative for homes with limited roof space, unsuitable roof orientations or large gardens where the panels can be positioned for maximum efficiency.
Quality aluminium and stainless steel mounting systems are designed to last for decades and are built to match the lifespan of modern solar panels, typically providing reliable performance for 25 years or more.
