Full Tilt by BCI

Number of pieces: 6

Certifications: UL 2703

Installation: The pre-galvanized roll formed sections are lightweight and can be handled by two installers. The rafter features a pivot point near the center of gravity, allowing the structure and loading of the modules in the flat position. Piles are driven with a pile driver, preferably a vibratory type. The balance of the system can be installed by hand with a 2-to-4-person crew using simple hand tools, battery powered tools speed up the assembly. Once the piles are driven and the components are properly staged, a 20-module table can be fully assembled in less-than one man-hour.

Advantages: The Full Tilt system has many cost and labor saving features and one the installers gravitate towards is the “Longhorn” panel rails that keep the modules perfectly aligned for quick fastening. The assemblers need not waste time adjusting the modules, alignment is automatically perfect. Another big advantage of the Full Tilt system is that it is designed to be built in the flat position. This means that all components can be assembled at a safe working height without need for ladders or workers climbing the structure. After the structure is assembled and panels fastened, the complete structure is easily and safely rotated to final position.

All components are made specifically for outdoor use with a life expectancy of 30+ years in the harshest conditions. Gripple’s Solar Bracing Solutions can be easily retrofitted to any existing system for any remedial work caused by external forces, such as realigning misshapen posts or to stop tables tilting and structures leaning.

What’s new in 2022?

Gripple debuted The CR-System range that includes lightweight above ground cable routing devices that are able to hold 1170 6mm2 of cables and have the potential to be stacked to increase capacity. Manufactured from polycarbonate UV Stabilized corrosion-resistant material, their free-air position can assist at design stage to de-rate and reduce the CSA on cabling used, providing further savings on project costs opposed to traditional trenching.



Material: All components are made specifically for outdoor use with a life expectancy of 30+ years in the harshest conditions. Gripple’s wire rope is coated with corrosion-resistant Zinc Aluminum and can be integrated as part of the frame with custom hot dipped brackets or looped around existing fixing points. The internal gripping mechanism is made up from a sintered ceramic roller offering a superior strength to alternative tension-only bracing systems with a load rating of up to 3,860 lbs.

The two-way locking device known as a PV Dynamic Tensioner allows you to install a brace quickly and easily between two piles. Applying pre-tension using a fast and unique tensioning tool the PV Bracing Kit will ensure the frame stays rigid, eliminating misalignment that might occur as the frame is installed. By bracing the first bay of an array, the setting out of the proceeding bays will be simpler, ensuring efficient use of materials. The kits are fast, lightweight and are delivered in ready-to-use kits drastically improving health and safety on-site.

Key feature: Kits come in requested ‘oversized’ lengths to allow for greater flexibility in the tolerance of frame installation and support a greater variety of mounting systems. To aid the installer, the Dynamic Tensioner component is releasable allowing the product to be adjusted prior to tensioning.

Stockton, Calif.-based Mechatron Solar is an international commercial and industrial solar project developer that manufactures unique, patented dual-axis photovoltaic trackers, each supporting 90 solar panels. The company’s unusually high-yield trackers have the highest energy density and the lowest ground footprint in the industry. Mechatron solar trackers include gearless azimuth trackers and gearless dual-axis trackers, which are designed to maximize performance with a lower operations and maintenance cost than other commercially available tracking systems. They have been successfully tested under different climate conditions rate structures constitute the best available solution for photovoltaic plant installation.

What’s new in 2022?

Mechatron was certified under UL 3703 this year and has a top-tier bankability analysis nearly complete. The flagship tracker also features a new digital guidance system, along with a new optional design with eight columns to accommodate large format modules. The new M16KD agriculture model features extra spacing between vertical panel stacks to permit more light to reach crops beneath the tracker, along with a new table-supported reflector option to enhance bifacial performance. The new M10KD residential model features a reduced table size to support 49 panels, to accommodate limited space requirements.



Posts per row: One reinforced concrete post or driven steel pile
Row length: Nine rows of 10 modules in landscape orientation; platform height 15 feet
Slope tolerances: Mounts in any terrain condition with virtually no slope limitations.
Certifications: UL 3703

Design: How is it constructed and how is it driven: The unique, patented MK18D features a gearless mechanism that eliminates the shear wear common with industry standard gear-driven trackers. The ball-bearing ring mechanism rotates the massive 90-panel platform around the azimuth axis with very high accuracy, zero-backlash and a hydraulic double-brake design. There are three hydraulic drives for azimuth motion and one hydraulic drive for elevation; these use standard single 3-phase 277/480V 1.5A Wye or 1-phase 120/240V 3A motors. These drive mechanisms permit a motion range of 360 degrees across the azimuth axis with 1 degree accuracy, and 0-60 degrees along the zenith axis with 1 degree accuracy. The tracker is designed to self-stow.

Advantages: As described above, the MK18D features a gearless azimuth drive ring, a hydraulic double brake mechanism, zero backlash and a self-stow feature. As a result of the superior solar tracking, the energy yield is 50% higher than a fixed-tilt ground mount and 20% higher than a single-axis tracker, where all three designs use the same number and type of modules. Bifacial panels add a 13% energy boost, several percentage points higher than single-axis and much higher than fixed-tilt designs, thanks to the 15-foot high panel table that captures more diffuse and direct reflection light than does the competition.
