Should I Use Micro Rails to Install Solar on Exposed-Fasten Metal Roofs?

Posted by Jesse Winternitz on Mar 9, 2020 2:15:51 PM

Micro rails are a relatively common way of attaching a solar array to exposed-fastened metal roofs. This method uses small rail sections in specific areas as needed along the roof – reducing the total length of rails. They have benefits which make them desirable to contractors and installers alike. They provide material and shipping cost savings to the customer when compared to rail systems. In addition, they are small, which allows them to be handled easily onto roofs. They are forgiving with spacing allowing for minimal or customizable walk spaces. Additionally, micro rails can be installed with just a couple of fasteners - potentially cutting installation times compared to rails.

Cost-Effective and Best Solar Panel Installation on Metal Roofs

Posted by Mark Gies on Nov 21, 2019 12:02:09 PM

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.

What is UL Listed?

Posted by Kimberly Reichert on Feb 21, 2019 8:33:31 AM

UL, an abbreviation for Underwriters Laboratories, is a testing and approving organization. Founded in 1894, UL performs safety testing on numerous electrical, mechanical, and chemical consumer and commercial products. Its roots began in electrical and fire safety, but UL now serves other industries and tests hazardous substances, water quality, food safety, and more.

How Do Solar Photovoltaic (PV) Panels Work?

Posted by Kimberly Reichert on Jan 23, 2019 10:22:15 AM

Photovoltaics (PV) is the process of converting light into electricity. PV technology converts sunlight (otherwise known as solar radiation) into direct current electricity. This process uses semiconductors, (the most common semiconductor material being crystalline silicon), so when the sun hits the PV, the electrons are released and form an electric current.

What is the Best Way to Mount Solar on Exposed-Fastener Metal Roofs?

Posted by Rob Haddock on Mar 8, 2018 1:48:02 PM


Upon reading the Solar Power World article Metal Roofs are No Problem for Solar Installations, my reaction was, "Well, I suppose that is true—if (and only if) it is done 'the right way.'" There are so many materials, profiles, gauges, metallurgies and corrosion behaviors to consider; not to mention effective waterproofing methods, sealant chemistries, thermal cycling characteristics, weathering behaviors, strength of materials, structural engineering principals and relevant test methods. It is anything but a simple science!

Cost Savings Best Practices for Solar Mounting on Standing Seam Metal Roofs

Posted by Dustin Haddock on Aug 24, 2017 1:24:58 PM

Standing seam metal roofing (SSMR) is the most convenient of any roof type for mounting PV modules, either crystalline or thin-film. The seams of SSMR are beam-like elements that not only add stiffness and flexural strength to the roof panels, but also provide expedient attachment points for a PV system. Joining PV modules to this roof type can be done with or without continuous mounting rails using aluminum seam clamps.
