Solar panels on corrugated iron roof

Project featuring the ValkPitched solar panel mounting system on a corrugated roof
Ask a question about this product

Corrugated iron roofs are often seen on industrial halls, barns and agricultural buildings. Installing solar panels on this type of roof is quite possible, but only with the right system. 

Incorrect fastening can cause damage, leakage or excessive load on the plate. With a suitable mounting system, the roof remains watertight and the installation safe. 

There are two common types: 

  • Fiberglass corrugated sheets  
  • Corrugated steel sheets 

What installers should pay attention to

When mounting on corrugated sheets, you should pay attention to: 

  • Fixing: Mount on the purlin, not just the corrugated sheet. 
  • Waterproofing: Use EPDM sealing for screws and profiles. 
  • Type of corrugated sheet: Check material (fiberglass or steel) and profile height. 
  • Mounting position: Attach to the top of the wave for sturdiness. 
  • Load capacity: Check that the structure can handle the extra weight. 
  • Cable pass-through: Hide cables neatly and waterproof. 

 

System for fiberglass corrugated sheets

With fiberglass corrugated sheets, you usually work with hanger screws. These are fixed in the substructure and ensure a secure installation without damaging the corrugated sheet. In combination with corrugated iron brackets , you bring the profiles to the right height. 

Suitable systems:

  • ValkPitched – Clamp: with hanger screws and clamp connection
  • ValkPitched – Insert: with hanger screws and insert profiles

Corrugated steel sheets

With corrugated steel sheets, you often use a corrugated sheet adapter (trapezoidal profile). This is attached directly to the roof plate and is suitable for landscape setups. 

Suitable systems:

  • ValkPitched – Clamp: with corrugated iron adapter or minirail solution 
  • ValkPitched – Insert: with insert profiles for tension-free mounting

The choice depends on the profile of the roof sheet and the desired arrangement. 

Both systems are available in blank, semi-black and fully black.

Customer talking

'The roof hooks for the ValkPitched - Smartline are attached to the wood with a screw system, which means they’re more securely fastened. Especially in areas with higher winds and in coastal regions, that’s the ideal solution, but for severe storms in general this system can withstand more than a system in which the roof hooks are hooked around the wood.'
