SOL-500 Roof Mounting System

The solar PV modules are often referred to as the heart of a solar power installation. But a tested, durable mounting system is equally important for the long-term profitability of a solar array. In other words: installing the best possible modules on the roof are of no use if they are not 100% reliably secured – and secure for 20 years.

This is especially true in Shetland where homes are subjected to gale force winds every winter.  Many residents up here have been stung by installation companies from the UK Mainland who don’t appreciate the difficulties of working in an ‘extreme exposure’ environment.  Panels installed by these companies have been blown off and roofs damaged.  As a local company Nordri are blessed with local knowledge, and are ideally placed to provide solar panel arrays which can withstand the harsh climate.

We have structural engineering experience in-house, and can undertake a detailed wind loading analysis for each house.  We design/specify/install solar panel arrays which are suitable for the Shetland weather.  Having the peace of mind that comes with a reliable mounting system is incredibly important!

Taking all this into consideration Nordri decided to use the SOL-50 mounting system.  These are manufactured by SEN, which is based in Germany.  We were impressed with the robust design of their products, and the simplicity with which they went together.  Check out this video to see what we mean:

The SOL-50 on-roof system is a universal mounting system for the secure and quick installation of framed solar modules up to 50 mm frame height. Stable construction combined with corrosion-resistant materials assures functionality of the solar system – and guarantees long life. The system is cross-connected and consists of vertical base and horizontal holding profiles which serve as insert frames. The SOL- 50 on-roof system is thus a safe solution for almost all types of roof.

Nordri have focused on the installation of ‘on-roof’ systems, dealing with both tiled roofs and those with corrugated sheets.  Information on these can be found in the relevant datasheets below:
