Stable connection, premium quality

As solar becomes increasingly common on new homes across Ireland, many homeowners and developers are looking for cleaner, more integrated solar solutions rather than the traditional “panels mounted above the roof” look.

One system that often comes up in discussions is the GSE in-roof mounting system. It’s frequently recommended for new builds because it allows solar panels to be integrated directly into the roof structure rather than mounted on rails above roof tiles.

But is it actually a good option for Irish homes? Let’s look at how the system works and whether it’s worth considering.

What Is the GSE Integrated Mounting System?

The GSE Integration system is a roof-integrated solar mounting solution designed to replace a section of roof tiles or slates.

Instead of mounting solar panels on rails above the roof surface, the panels sit inside specially designed trays that form part of the roof covering itself. Once installed, the solar array sits flush with the roof, creating a much sleeker and more architectural appearance.

The trays include integrated:

- Waterproof flashing - Drainage channels - Mounting points for standard framed solar panels

This allows the system to work with many popular residential solar panels rather than requiring proprietary modules.

Why It’s Popular for New Builds

For new construction projects, systems like GSE can make a lot of sense because they integrate directly into the roofing stage of the build.

Cleaner Aesthetics

Traditional solar systems sit on top of the roof on metal rails, which can be visually noticeable.

In-roof systems sit flush with the tiles, creating a much more streamlined look that many homeowners prefer.

For modern homes and new developments, this can make a big difference to the overall architectural finish.

Ideal When the Roof Is Being Installed Anyway

If you’re installing solar on an existing house, removing tiles and installing integrated trays adds labour.

But for new builds or full roof replacements, the roofing work is happening anyway. This means an integrated system can be installed during the normal roofing process, making it more efficient.

Solar Panels That Work Well With Integrated Systems

One of the advantages of the GSE system is that it works with standard framed solar panels, giving homeowners flexibility when choosing modules.

If you’re researching solar panels commonly used in Irish residential installations, we’ve reviewed several high-efficiency options:

All of these are popular panels used in residential solar installations and are compatible with most modern mounting systems, including integrated roof solutions.

For in-roof systems, installers often recommend all-black solar panels, as they blend more naturally with the roof and create a cleaner finish.

Choosing the Right Inverter

Along with the mounting system and panels, the inverter is one of the most important components of a solar installation.

Are There Any Downsides?

Like any solar mounting solution, integrated systems have a few trade-offs.

Slightly Higher Installation Cost

Integrated systems can be a little more expensive than traditional rail-mounted solar because of the additional mounting trays and roofing work.

However, when installed during construction, the cost difference can sometimes be smaller.

Installation Quality Is Critical

Because the mounting trays replace part of the roof covering, roofing details and flashing installation are extremely important.

Choosing an installer with experience installing in-roof solar systems is essential to ensure the roof remains fully weatherproof.

Slightly Less Ventilation

Traditional solar panels sit above the roof with airflow underneath them.

Integrated panels sit closer to the roof surface, which can slightly reduce cooling airflow. In practice this usually results in only a small difference in performance, but it’s something installers consider when designing systems.

Is the GSE System a Good Option for Irish Homes?

For many projects, especially new builds, the answer is yes.

Integrated solar mounting systems offer:

- cleaner roof aesthetics - good weather protection - compatibility with standard solar panels - easier integration during construction

As solar becomes standard on new homes across Ireland, systems like GSE are becoming increasingly popular with developers and homeowners looking for a more architectural solar solution.

Final Thoughts

The GSE integrated mounting system is a neat and practical option for homeowners planning solar during the construction stage.

While traditional rail-mounted systems remain the most common solution for retrofits, integrated systems offer a cleaner appearance and seamless roof integration that many homeowners prefer.

As with any roofing component, the key factor is installation quality and working with experienced solar installers.
