There is a solar structure and electrical system for every space you encounter. From Midwestern mall parking lots to Northeastern landfills to vast rocky desert landscapes — and all of those solutions are listed in this 2023 Ground-Mount Solar BOS Buyer’s Guide.
For this year’s Ground-Mount BOS Buyer’s Guide, we reached out to suppliers of both structural balance of systems (sBOS) and electrical balance of systems (eBOS) for this all-in-one product showcase. Some trends to note:
Terrain following trackers. This is not a new phenomenon, but it is one to pay more attention to. This year we asked each racking and tracking company to provide slope tolerances and posts per row. Some systems have made incremental improvements, while one or two others have debuted a totally new design to handle seemingly any undulations.
Elevation. Pole mounted / elevated dual-axis trackers fell out of favor at one time, but 1) system reliability has improved and 2) various site constraints make their value proposition compelling. Why construct a carport when a few sun-following trackers might be a better fit? Agrivoltaic applications are also intriguing here.
Above ground cable management. There are more options available in this category than ever before as more and more EPCs and IPPs realize the benefits of this design strategy.
More utility-scale players. Array Technologies and Nextracker are by far the top two brands in terms of tracker market share*, but many mounting manufacturers have developed and proven their system reliability in C&I and community-scale projects and are now serving utility-scale size projects — and can often do so with shorter lead times.
NOTE: Click on on any product listed under each manufacturer in order to expand the section and see what it looks like, check out the specs, understand how to install it and learn a few other key features of the design.

Specialty: Headquartered in Ashland, Oregon, Stracker Solar has been manufacturing, selling and installing its state-of-the-art elevated dual-axis solar trackers since 2017. The pole-mounted Strackers are robust and elegant solar power systems specifically designed for maximizing distributed generation in urban environments. These giant mechanical sunflowers offer compatibility with a broad range of project sites by allowing full use of the ground below and generate up to 70% more solar energy than conventional fixed PV systems of the same size. They are patent-pending and UL 3703 listed.
What’s new in 2023? Based on the success and the outstanding performance of Stracker installations across a variety of climates and terrains in northern California and southern Oregon, Stracker Solar has embarked on a national expansion initiative. The company has been contracting Regional Fabrication Facilities and EPC Distributor Partners across the country for the national roll-out of its elevated dual-axis solar trackers.
Row length range: Single pole-mounted design with 4 panels in a row in landscape orientation, 7 rows, (28 total)
Slope tolerances: Mounts in any terrain condition. However, for allowing full tracking range, 45 degrees is the maximum recommended slope. Above that, tracking range needs to be customized to avoid array hitting the slope.
Certifications: UL 3703, Load-tested wind rating of 120 mph
Installation: The small 24-in. footprint of Strackers with a single pole enables easy installation across a wide variety of urban and rural environments, including hilly and difficult terrain. Foundation typically consists of 30-in. diameter reinforced piers. The 20-ft tall pole of the structure is tied to the foundation with four anchor bolts, making for easy relocation if ever needed.
The heart of the Stracker tracking system is a proprietary Drive-core (consisting of slew-drive actuators, electric motors, and control electronics), which is mounted at the top of the pole using a steel assembly and a structural bolting system. Then the array with the panels is lifted and secured atop the Drive-core.
Unique software capabilities: The control system incorporates a sophisticated, proprietary, GPS-based algorithm to track the precise location of the sun in the sky and adjusts the solar panel direction utilizing the Drive-core’s dual-axis movement capability. The enterprise-quality control system utilizes internal proximity sensors to assure the highest-quality algorithm solar tracking commercially available. It provides monitoring and automated procedures to protect against extreme weather events including high wind loads of up to 120 mph.
- Strackers provide maximum solar energy production with the smallest mounting footprint.
- They allow full use of the ground below with a 14-ft minimum clearance that easily accommodates semi-trailers, fire engines, buses and large farm equipment.
- Designed specifically for dual-use solar sites: parking lots, agricultural and industrial operations, campuses, other open spaces.
- Solar panels, electrical and mechanical equipment are lifted 14 to 35 ft above the ground, so there’s no need for fencing.
- Generates 50-70% more solar power than conventional fixed PV systems of the same size.
- Built in the U.S. of American-made steel.
