The quality of a rooftop solar PV array depends on the brackets and rails on which it is mounted. Below we present the latest updates from 16 manufacturers of residential, commercial and industrial solar mounting systems, with widely varying approaches. In living quarters, some improve on the proven crawler configuration with metal pads, while others venture the trackless, deck-attached approach. In the commercial and industrial sector, metal roof mounts, the emergence of molded plastic brackets, and even attempts to use roof trackers are popular.
EcoFasten, an Esdec company, provides easy-to-install and cost-effective rooftop solar PV mounts and mounting systems for the US solar industry. In business since 2007, the company’s extensive portfolio of proprietary waterproofing solutions can be configured for every type of roof.

Installation: Installing a RockIt railless system on a composite tile roof is not only one of the most cost effective solutions on the market, it is also one of the quickest and easiest to install thanks to the use of EcoFasten waterproof overlays that use a single bar. clasp. Once the flashing with the RockIt rails was in place and aligned with the edge of the eaves, the installation of the first row of RockIt brackets, array skirts and sleeves began. It remains only to install the photovoltaic modules and proceed to the installation of lifting brackets and couplings. Level the rest of the system at any time or after the solar array is installed.
Benefits: The RockIt system is an industry leading trackless photovoltaic mounting system available in combination tile, tile and metal roof configurations. Designed specifically to meet the needs of installers, RockIt provides quick and easy one-tool installation and uses EcoFasten’s patented waterproof technology. With convenient, easy-to-position leveling rails and a top-down leveling system, RockIt is logistically efficient and eliminates the need to ship or transport long rails. The RockIt system offers simplified installation, fully integrated connection and north-south adjustment. The components are available in black and are suitable for commercial and residential applications. RockIt complies with UL 2703.

How to Install: The SimpleBlock-PV comes with two pre-installed oval set screws for super-fast installation on standing seam metal roofs. To attach the SimpleBlock-PV, place the block (clamp) on the standing seam, then lift the block until the tab engages the underside of the seam metal roof seam, then tighten the set screw to 150 in-lbs.
Install the first row of blocks with end spacers and middle clips. Gap blocks connect adjacent PV modules from north to south, while couplers connect and link adjacent PV modules from east to west. Install the remaining blocks, intermediate clamps, couplings and PV modules on the top layer as needed.
Benefits: SimpleBlock-PV is an innovative railless shelving system for metal seam roofs. The system uses EcoFasten end struts and intermediate clamps with an integrated connection, and the blocks (clamps) feature two pre-installed oval set screws to ensure quick and easy installation without worrying about these tiny components slipping off the roof or falling off. Maintaining the integrity of the roof is a priority for EcoFasten, a three-part system using sandwich technology that eliminates the need to penetrate the roofing material. SimpleBlock-PV is suitable for most metal roofing profiles with a double standing seam lock, has a north-south adjustment and is UL 2703 compliant.
How to install: After the installation site is determined and the roof and insulation are cut to accommodate the base plate, install the flashing on the two threaded studs on the base plate, then install the EPDM gasket on the two threaded studs. Place the F-202 compression cleats on the threaded studs and place an adhesive washer on each stud with the rubber side facing the roof. Thread the hex nut along the stud onto the compression bracket before adding it. Install and tighten a hex nut on each stud. Then attach a mounting bracket or post of your choice to the F-202 using the supplied full thread, and finally make the EFL-BLK-1014 waterproofing by following the special roofing membrane technique.
Benefits: The ECO-65 is a special fixture for installation directly on a low pitched roof. This roof mount is specially designed for use on new or existing (refurbished) low pitch roofs made from bitumen rolls or membranes (TPO, EPDM, PVC). ECO-65 is used by countless manufacturers of ballast solar racking systems to reduce weight and increase the impact resistance of their products. The ECO-65 baseplate is specifically designed to mount to wood blocks or wood floors, the mount itself has two studs for mounting, allowing you to use a larger compression strut if needed. ECO-65 is a waterproof solution compatible with any shelving system.
Number of Pieces: 4 Tools Required: Two tools (¼” hex socket, ½” socket) Certifications: UL 2703 compliant
How to install: Locate the array, mark the center of the corrugation, and draw a line to indicate where to install the mounting loop. Double check the width of the ridge (minimum 3/4 inch) and the thickness of the metal (minimum 26ga). The required number of screws will be determined by the screw number table. Attach mounting profiles with self-tapping screws and a 1/4″ hex cordless drill. Self-tapping screws are installed perpendicular to the roof surface to create a waterproof seal. Next, end clamps are installed on the first two mounting profiles closest to the eaves. Attach the bottom end brackets to the mounting rails and snap the clips onto the side flanges. Place the first module, align and slide the end clips flush with the module frame. Tighten the end clamps and start installing the middle clamp. Repeat for each column of modules, using the latch of the middle clip as a retainer. spacers to ensure a constant EW gap between modules. Benefits: The RibFit system is an easy-to-install 4-piece trackless solar panel racking system designed for use on metal roofs. The RibFit system is UL 2703 compliant and consists of aluminum panels that mount directly to the top of the ribs of the metal panel Slider Composition Few components and integrated key pins reduce installation time compared to track-based systems RibFit fits modules in landscape orientation and is compatible with most metal R-panels and trapezoidal roof panels with a ridge width of 3/4″ or greater and a thickness of 26 or greater. The RibFit system has three levels of waterproof protection for durability and peace of mind.
How to Install: QB-1 on Tiled Roofs: The QB-1′s strong, versatile stand and base make it ideal for installing solar panels on tiled roofs. First locate and mark each row of fasteners. Align the vertical mounting holes of the QB-1 base with the center rafter mark, then align the horizontal mounting holes with the aligned row lines. Remove the QB-1 mount and place it over the pre-drilled and filled pilot holes and secure the mounts. Fix the post on the QB-1 base.
Once the underlay is in place, install the tile level plank, cutting where necessary to allow the posts to pass through. Return the cut tile to its place and apply sealant at the junction of the post and plank. Install the necessary brackets or L-shaped feet to complete the installation.
BENEFITS: Heavy-duty and versatile, the QB-1 Tracked Shelving System includes a base that attaches to a variety of roof types, including composite shingles, shingles, slates, slates, and metal shingles. The QB-1 is ideal for use in new residential projects as it allows roofing or shingles to be laid around installed brackets. Aluminum cone moldings are also available, sized to match the racks. Simply align the base with the rack height of your choice (available in 4.5″ or 6.5″ rack heights), select the flashing (12″ x 12″ or 18″ x 18″) and select the desired bracket.
Mounting: MLPE frame mounts attach, mount, and fully mount module-level power electronics (MLPE) to the module frame with a single-bolt clamp.
Key Features: This accessory can be used with any shelving system by connecting the MLPE to the modular frame.
