Being the experts on all things metal roof and metal roof attachments, we are often asked by solar developers and installers what is the most cost-effective way to install solar panels on metal roofs. There are multiple options when putting solar on a metal roof, and each come with pros and cons that can impact installation costs and lifetime performance.
Did you know that your roof already comes with free rails? You can mount PV directly to the roof panels themselves - using the “direct-attach” method. Whether you are dealing with standing seam or ribbed, face-fastened panels, these metal roofs have one thing in common: They all have built-in rails. (See image to the left: Standing seam metal roofs have rails (the seams) built right in ready for direct attachment of solar panels.)
When it comes to sharing solar array costs, companies often shy away and dance around the question. They usually focus on the customization angle – telling you that prices vary, and that this is what makes estimation difficult.
Now, of course costs vary, because no two projects are the same but whether you are an installer, contractor, or a homeowner, you share two common questions:
How much is this going to cost me and how long is it going to take?
