Install: 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 due to external forces and environmental loads. The ready-to-use kits are fast and lightweight, drastically improving health and safety on-site.

Key feature: Kits come in oversized lengths to allow for greater flexibility in the tolerance of frame installation and to 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.

Gripple offers a range of lightweight Solar Anchoring Kits which attach to solar frames to increase resistance to external loads. These are ideal for use supporting existing piles where ground conditions require additional anchoring, as well as for realignment and repair where ground mount frames may become misaligned.

Installation: The Gripple Anchors can be quickly and easily driven into the ground using just hand tools. The innovative install and ‘flip’ of the PV Anchor accesses the soil’s engineering properties with minimal disturbance. The PV Anchor is then activated by tensioning the wire around the PV racking using a Gripple Dynamic tensioner – allowing the system to offer increased protection against uplift despite requiring considerably less materials.

Sunfolding maximizes profitability with innovative solar tracking technology. Powered by air, the Sunfolding T29 Single-Axis Tracker deploys on land previously off limits to utility-scale solar. The Sunfolding T29 also makes solar plants faster to install and easier to operate. Sunfolding has won recognition as a 2020 Global Cleantech 100 Company and a 2019 Bloomberg New Energy Pioneer. Headquartered in Alameda, CA, Sunfolding ships US-manufactured trackers throughout North America.


Projects above 5 MW, especially those that can benefit from earthwork savings.

What’s new in 2022?

Working closely with our customers, Sunfolding has scaled down the T29 Single-Axis Tracker to two posts so we can navigate terrain and topographic features with even more flexibility and at no added cost. To begin with, actuation on every post brings unparalleled flexibility. The ability to reset tracker tables every 25 to 30 feet vastly improves tolerances on the east-west axis and in terms of tracker height. Dips and swells at ground level no longer have any impact on system design. A tracker can go from a steep rising slope to a steep falling slope or anything in between. Instead of designing one 300-foot span at a time, take advantage of the granular ability to follow terrain undulations from one plane to another and another and reduce earthwork by more than 90%.

Number of pieces: 3 structural components

Row lengths: 1 to 2 strings in length

Slope tolerances: Up to 12.3% grade slopes with no change to standard product

Design: With just three unique structural components, Sunfolding makes construction easier. From the post all the way to the modules, we streamline and expedite the installation process. By reducing the number of post sizes that you’re dealing with, we have reduced the possibilities of misplacing a post or misdriving a post. With a shorter post embedment depth, Sunfolding minimizes interaction and contact with subgrade rock.

Advantages: The Sunfolding T29 optimizes solar tracking and maximizes energy output. Unlike motor-driven trackers, the Sunfolding T29 makes solar infrastructure simple again. Sunfolding projects neutralize costs with flexible layouts that fit the trackers to the land. Small tracker tables enable denser DC per acre without driving up costs and reduce earthwork by more than 70%. Fewer components makes every project simpler and allows for a reduction in construction costs by more than 15%.
