Keep part counts low
The Low Profile QuickBOLT with Microflashing from SolarRoofHook can be installed in less than 60 seconds, and the key is its Microflashing technology, which is installed on top of the shingles and eliminates the need to pry apart shingles and shove oversized aluminum flashing underneath.
“We would like to see installers move away from the old-school aluminum flashing method and replace that with Microflashing technology,” said Samantha Dalton, marketing manager for SolarRoofHook. “Using Microflashing reduces installers risk too. When installers are forced to separate shingles to install aluminum flashing, they often must remove nails from the roof. This leaves open penetrations in the roof, as well as leads them to risk voiding the roofing warranty and breaking code. Microflashing doesn’t pose those same risks and bonds with the roofing material to create a watertight seal.”
Quick Mount debuts new full rooftop rail system
Quick Mount PV is simplifying your supply chain with QRail, its new rooftop racking system featuring patented QClick and QSplice technologies that simplify and speed installation. QRail combines with Quick Mount PV’s waterproof mounts to create a complete, fully-integrated racking and mounting solution for installing solar PV modules on any roof.
The patented QClick technology enables module clamps to easily click into the rail channel and remain in an upright position, ready to accept the module. QRail’s QSplice is the fastest, most efficient splice in the industry — a tool-free, bonded, fully-structural splice that installs in seconds with no extra hardware required.
Electrical bonding is fully integrated into every system component. All electrical bonds are created when the components are installed and tightened down. QRail is fully code compliant, certified to UL 2703, and backed by a 25-year warranty.
As a best practice, Jason Xie, president of Magerack, recommends assembling components on the ground as much as possible and avoiding assembling tiny components such as rubber washers on the roof.
For example, Magerack solar mounting components don’t contain any rubber components and all components are pre-assembled out of box. Magerack roof attachment doesn’t need any rubber washer and has no tiny components except pre-assembled fasteners. The two major components of MageMount MageMount II Rail-less Solar Mounting System, module connector and module brackets, can be assembled to the solar module on the ground before moving them on the roof. Module connectors are used to connect and secure two adjacent solar modules along the same row or between two rows. Those connectors and the roof attachments can be attached anywhere along the module edge where they are needed the most.
Look to kits
Consider systems where only a single tool is required for installation. Take Unirac’s SunFrame Microrail or the new Pro Series SM for example. Parts come pre-assembled out of the box making for a quick and easy install on the roof. There is no need to fumble with loose parts and pieces. Parts can be pulled from the box and can be put straight to use.
“One tool installation saves time on the roof, eliminating the chance of dropping tools while changing sockets,” says Anthony Romero, lead trainer for Unirac.
The SM Pro Series features module agnostic mid and end clamps. The end clamps secure the module while staying beneath the module. Arrays look very clean and appealing without any rail or hardware protruding. The mid clamps come pre-assembled and are self-standing. They also come coated with anti-seize to prevent galling and breaking stainless steel bolts. Unirac’s FlashKit Pro comes in a pack of 10 with flashing, L-Feet, T-bolts and lag bolts in one convenient box. Having everything in one package helps cut down on the amount of packaging needed on the roof. They are the easiest flashing kit to count, kit and carry to the roof.
The SunRunner 4 clip from Heyco was developed to reduce the number of SKUs for an installer. For those using a mix of SolarEdge and Enphase, this clip will handle both types of cable. The SunRunner 4 clips directly onto the PV module frame and holds up to four SolarEdge cables or up to three Enphase Q cables comfortably. The SunRunner 4 takes the guesswork out of ordering the correct clip as it holds both types of cable. Heyco also manufactures top rail clips with the exact same clip design as its SunRunner 4 for top racking manufacturers like Unirac, IronRidge, and Everest. This universal design allows the clips to be used on a wider range of installations and reduce the number of SKUs (and headaches) for installers. Heyco also offers a series of nylon UVX clips which qualify for its 20-year warranty and are generally 20 percent less expensive than their stainless steel equivalents.
Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
