Welcome to this installment of SPW Classroom on Roof-Mount Systems.
Solar panels can't do their jobs of making energy if they aren't successfully secured to a roof, whether it is sloped or flat. Roof-mounts can use rails, be rail-less and even depend on ballast, but they all must clamp to solar panels in some way.
Here you will find resources describing the various types of racking and mounting systems used on rooftops. These tutorials are all designed to give you a better understanding of this important mechanical component of solar arrays.
Railed vs. rail-less mounting for rooftop solar projects
What are the different types of solar flashing?
What are the different types of solar mounting systems for roofs?
Metal roofs are no problem for solar installations
Without flashing, a residential roof with solar might become a leaky mess. When holes are made in a roof—for vent pipes or solar mounts—flashing is the material used to stop water from leaking into the roof.
Probably the most competitive solar product market, mounting systems are an important element of solar arrays—they secure solar panels to the roof or the ground.
The standard rail-based mount is popular with sloped rooftop installers, but rail-less systems have their advantages in the right scenario.
For solar installers most familiar with comp shingle or tile roofs, encountering a metal roof can be challenging.
QB2 only has 3 components and can be installed in less than 30 seconds. QuickBOLT is the only Top Mount in the industry that uses BoltSeal™ technology, which allows QB2 to be mounted on a variety of asphalt shingle, EPDM, and TPO roofs that other flashing cannot.
Explore new lines of income for your solar installation business with QuickBOLT’s Stone Coated Steel roof mounts designed in partnership with metal roof manufacturers themselves. These SCS roof mounts work on all metal tile profiles and will help you bring in money you’re missing out on.
QuickBOLT’s new Conduit Mount for Asphalt Shingle, TPO and EPDM roofs features a 7/8” high EPDM Cylinder that lifts the conduit off the roof to meet NFPA Code. Installers can use this in combination with their conduit shoulder clips for supporting conduit on the rooftop.
Save time with the Deck Mount by skipping the step for finding rafters. The base of the mount has Silicon embedded into it and is secured to the roof with Stainless Steel Screws assembled with Umbrella Washers for superior holding and water protection.
Flexible Flashing Wins the Day for Michigan’s Strawberry Solar
With most of its land bordered by the Great Lakes, Michigan can pose numerous challenges for solar installers. In Detroit, the home of Strawberry Solar, the average overnight temperatures in January linger just under a frigid 18°F. Joe Nagle, founder of Strawberry Solar, added that Michigan’s utilities have eliminated net metering which increases the cost of solar for consumers, but solar is slowly gaining acceptance in the state.
Since the dawn of the solar industry, PV installers have struggled with mounting systems that put the roof at risk by drilling holes into rafters that can damage shingles and cause leaks. In 2013, Roof Tech introduced its innovative flexible flashing technology with RT-Butyl, and those risks quickly faded into the past. Now, Roof Tech brings you AlphaSeal™ Technology, the impenetrable sealant that eliminates the need for caulking once and for all.
Freezing Winter Weather is No Match for Roof Tech AlphaSeal™ Technology
For Peak Performance in Extreme Weather, Roof Tech’s AlphaSeal™ Technology Delivers
Most manufacturers of asphalt shingles recommend a minimum ambient temperature of 40°F before doing any work on asphalt roofing because of the danger of shingles cracking,” explained Mike Dunlap, Roof Tech Sales Director. “But Roof Tech’s flashing with AlphaSeal™ Technology eliminates the need to lift shingles and delivers an impermeable seal in temperatures as low as 22°F. Installation crews working in temperatures below 22°F also know to use heat guns to warm the AlphaSeal™, so it softens just enough to form an impermeable seal.
Annual temperatures in Edmonton, Alberta, Canada, range from a high of 90°F in summer to a low of -40°F in mid-winter. With such extreme fluctuations in weather, solar installers in that region require mounting solutions that are impervious to these changes.
