Get the right metal roof application with Renusol

Metal is a popular roofing option due to its durability and light weight. The long lifespan of metal roofs makes them a particularly attractive choice for the environmentally conscious, which is where solar comes in.

Many companies choose to install a PV array on metal roofs for a long-lasting and sustainable renewable energy supply. However, because there are so many variations of metal roof types, there are many options for mounting the PV panels.

So, which roof types require which mounting applications, and why does SegenSolar recommend Renusol for the job?

Which mounting system is suitable for your roof type?

Each type of metal roof has a slightly different surface environment. Factors like the amount of flat space available and whether the surface can, or needs to be, penetrated influence how PV panels should be mounted.

Standing-seam metal roofs comprise broad, crimped metal panels with continuous joints and raised seams. Because this roof type cannot be penetrated (to preserve the watertight seal), it is ideal for clamps. This non-penetrative mounting method is also used for metal tile roofs.

Corrugated metal roofs, on the other hand, are slightly more complex. Solar panels can only be installed on these roofs via penetration, which calls for a specialised mounting system. Panels can be mounted with brackets and built-in rubber plugs or sealant. Due to their shape and the subsequent lack of flat areas, trapezoidal metal roofs also require brackets.

It is also worth considering the angle of the panels to ensure optimum sun exposure. In this case, rails may be the best option. The number of rails needed will depend on whether the roof will be subject to extreme weather conditions; strong winds necessitate more rails, for example.

The experts at SegenSolar recommend Renusol for all your solar needs. This PV mounting specialist has 20 years of experience delivering reliable mounting solutions that are built to last — just what you need for a sustainable energy supply.

Which Renusol mounting solution should you choose?

There is a Renusol mounting system for every type of metal roof installation. Which products you choose depends on the roof type and the environment it is located in.

For trapezoidal and corrugated sheet metal roofs, Renusol offers the MS+ range. With short, non-continuous rails, these systems conserve space and reduce transport costs, making for a straightforward, cost-effective installation.

Variations of the MS+ range allow you to adapt your mounting solutions to suit your needs and preferences. Whilst the Renusol MS+CORRUGATED is suitable for corrugated sheet metal roofs, the MS+P is designed for portrait installation, and the MS+H can withstand higher temperatures — the perfect solution for hot climates.

The TS+ is a flexible triangular elevated mounting system that is compatible with almost all roof types when installed with hanger bolts, solar fasteners and standing-seam clamps. With the Renusol MS+, this system can be adjusted to suit trapezoidal and corrugated sheet metal roofs with a mounting angle between 10 and 35 degrees.

Renusol’s patented universal fastening application, the VS+, can support medium and high loads with hooks, hanger bolts and standing-seam clamps no matter the installation. Such flexibility opens up a world of installation possibilities.
