When considering solar panel installations, one of the decisions you may face is choosing between rail-mounted solar panels and an in-roof solar installation.
Let’s explore the differences between these two popular installation methods, along with their advantages and potential costs.
Rail-Mounted Solar Panels
Rail-mounted solar panels are the most commonly used system for most buildings. This method involves mounting the panels on a rail system that sits on top of your existing roof. The installation process is fairly straightforward, with the rails being secured to your roof trusses, allowing the panels to be attached and aligned for optimal sun exposure.
Key Benefits:
Versatile: Rail-mounted systems can be installed on almost any roof type, whether it’s a flat roof or pitched, and they work well with most roofing materials.
Easier Maintenance: Since the panels are raised slightly above the roof, there’s easy access to the system for cleaning and any future repairs.
Cost-Effective for Retrofits: For homes or buildings with existing roofs, this is often the most economical solution, avoiding the need for any significant roof modifications.
In-Roof Solar Installations
In-roof solar installations (also called integrated solar) involve embedding the panels directly into the roof structure itself. Instead of being mounted on top of the roofing material, the panels replace part of the roof, functioning as both the roof covering and the energy generator. This installation is most commonly seen in new builds or when a roof is being fully replaced.
Key Benefits:
Sleek Aesthetic: In-roof solar installations offer a more streamlined and modern look, as the panels sit flush with the roof, blending seamlessly into the design.
Reduced Wind Load: Since the panels are integrated into the roof, they are less exposed to wind uplift compared to rail-mounted systems, making them a robust option in areas prone to high winds.
Ideal for New Builds or Re-Roofs: If you're building a new home or replacing your roof, an in-roof system can be cost-effective because the panels eliminate the need for traditional roof tiles or slates in the installation area.
Comparing Costs
When it comes to cost, in-roof systems generally come at a premium compared to rail-mounted panels. On average, the price difference is about 10% more than the price of a rail-mounted system. For example, a rail mounted system costing £8,000 would be roughly £8,800 for an in-roof system. However, this cost can often be offset in new builds or when replacing an entire roof, as the panels serve a dual purpose: both roof covering and energy generation.
For new builds and re-roofing projects, the price gap between rail-mounted and in-roof installations tends to narrow or even disappear, making it a viable and attractive option for homeowners seeking both functionality and design.
Which System is Right for You?
The choice between rail-mounted and in-roof solar installations depends on your individual circumstances:
For existing roofs, rail-mounted systems are likely the most cost-effective option. They offer flexibility in design and are easier to install without disrupting your existing roof structure.
For new builds or re-roofing, in-roof systems may be the better choice, especially if you prioritise aesthetics and want to incorporate the solar system into the overall design of your home.
Both rail-mounted and in-roof solar installations have their distinct advantages, and the decision ultimately comes down to your specific project and preferences. While in-roof systems tend to be around 10% more expensive for retrofits, they offer long-term value, especially for new builds and major roof renovations. Whatever your choice, investing in solar energy is a smart step toward sustainability and energy independence.
