What type of solar panel installation is right for you?

So, you're considering going solar? That's fantastic! One of the first things to think about is the type of installation that will work best for your property. There isn't a one-size-fits-all solution, as each installation method comes with its own set of benefits. Your specific circumstances will play a key role in determining the ideal option. Let's take a look at the different types of solar panel installations we specialise in.

In-roof systems

  • Sleek, Integrated Design: In-roof panels replace traditional roofing materials, offering a visually unobtrusive and architecturally appealing solution, especially favoured in conservation areas.
  • Structural and Maintenance Benefits: Their lightweight, flush-fitting design reduces structural load, prevents bird nesting, enhances wind resistance, and lowers long-term maintenance costs.
  • Ideal For New Builds and Renovations: Despite slightly lower airflow efficiency, ongoing technological improvements make in-roof systems a cost-effective and sustainable choice for modern construction projects.

 

We use the Sunfixings in-roof mounting system, which is fully compliant with the latest version of MCS 012, meeting all current standards for weather tightness and fire resistance. Its integrated design ensures a secure, durable, and aesthetically pleasing solar installation that maintains the integrity of the roof while delivering long-term performance and regulatory assurance.

On-roof systems

  • Efficiency and Cost: Elevated on-roof panels improve cooling, boost efficiency and lifespan, and are cheaper and easier to install—great for retrofits.
  • Maintenance and Flexibility: Easier to maintain, expand, and adjust than in-roof systems, with passive cooling that lowers building heat and AC costs.
  • Aesthetics and Upkeep: More visible and require bird proofing and cleaning to prevent performance issues from nesting and debris.

 

The type of roof tile determines the appropriate fixing method for attaching solar panels to the roof structure. Typically, roof hooks are secured to the rafters, with mounting rails attached to the hooks to support the panels.

Some of the mountings systems we’ve used are Clenergy, K2, Renusol and Sunfixings.

Flat roof systems

  • Enhanced Solar Efficiency: Flat roofs provide generous space and flexible panel positioning, allowing for optimal sunlight exposure and increased energy generation.
  • Cost-Efficient and Sleek Design: Their simple design and easy access reduce installation costs, while the low-profile panels help maintain the building’s clean, modern look.
  • Reliable and Resilient Performance: With thoughtful design and regular upkeep, flat roof systems deliver long-term efficiency, added cooling benefits, and strong resistance to environmental factors.

 

For all flat roof solar installations, we ensure your building’s structure is fully assessed to support the additional load of a solar PV system.
This includes engaging a qualified structural engineer to conduct a comprehensive survey, ensuring compliance with safety standards and long-term performance.

We partner with industry-leading mounting system providers such as Van der ValkESDEC, and Sunfixings, offering robust and scalable solutions designed for all suitable rooftops.

Ground Mounted Systems

  • Flexible Installation Location: Ideal for properties with limited roof space or for large-scale solar farms, offering greater placement versatility.
  • Optimised Energy Production: Allows for ideal tilt and orientation to maximise sunlight exposure and improve overall energy output.
  • Ease of Maintenance and Scalability: Easier access for repairs and maintenance, with the ability to expand the system as energy demands grow.

 

Different terrains require specific solar mounting solutions. Flat land suits fixed-tilt systems, while sloped areas benefit from adjustable or terraced mounts. Rocky ground may need special drilling or ballast systems, and soft or flood-prone soil often requires elevated or helical pile foundations.
