An important feature that distinguishes our panel frames and manifolds from those of some of our competitors is the quality of the materials and the finish. 

In this picture you can see a comparison of a member from our panels and from a competitor.
The competitor's frame (on the left) is made of folded steel sheet metal and is not particularly sturdy. Our frame (on the right) is made of much thicker extruded aluminium which is powder coated (anodised).  This makes our panels stronger and with excellent corrosion resistance.  This ensures that the panel on your roof will remain looking good for the whole of its working life.
