Soltec is supplying complete tracker equipment to the 13-MW Eagle Point solar PV plant located in the state of Oregon by leading project developer Cypress Creek Renewables.
“Our trackers require the fewest piles per megawatt and keep earth grading operations to a minimum, preserving the site’s wetlands and fragile ecosystem,” reported José María Lozano, Engineering Global Director at Soltec. “Our independent-row, short tracker site-fill advantages allowed the plant to be designed with the trackers arranged diagonally, rather than in a straight line, to make the most of the available land.”
The 491 complete solar trackers manufactured by Soltec present a market-leading cost advantage. The trackers will be produced and shipped in less than 40 days to the project site on the outskirts of Medford, near the Rogue Valley International Airport.
“We are proud to be chosen once again by Cypress Creek Renewables,” said Raúl Morales, CEO of Soltec. “Customer success comes from combining cost-effective, high-yield equipment offering high-tolerance installation features with Soltec’s proven reliability as a tracking partner.”

At Solar Power International, we chatted with Elie Rothschild, sales manager at Sollega, a leading commercial solar racking manufacture. He mentioned that Sollega’s injection molded FastRack 510 withstood 190 mph sustained (Category 5) winds of Hurricane Irma. Nearly 90 percent of the 900 kW array on the Westin Hotel are still attached to the racking and on the roof. Here is the before and after:
The array was installed using Sollega’s patented FR510 ballasted/hybrid racking system. The fully adhered single ply membrane roof utilized a combination of heat weld mechanical anchors and ballast block.

Reliability and reduced O&M costs are key metrics when choosing among solar tracking systems. At SPI, TÜV Rheinland reveals an in-depth study of Array Technologies’ DuraTrack HZ v3 that indicates the DuraTrack is “300 × less likely to experience catastrophic failure during wind events than single-row competitors that rely on stow.”
Array Technologies is the main supplier of centralized drive trackers in the industry, which the company maintains allows for a robust design and a unique wind mitigation strategy that avoids module stress, fatigue failure and torsional galloping issues during high stress wind events.
TÜV analysts performed an economic and risk analysis of two tracker architectures: one layout driven by a single motor linked by a rotating driveline to multiple tracker rows; and a competing design where tracker rows operate as self-contained units, each with a dedicated photovoltaic (PV) panel, battery, motor and other system components. TÜV’s analysis includes descriptions of the technical characteristics of each system, followed by a failure modes and effects analysis (FMEA) to assess risk associated with component failures, and concluding with a levelized cost of energy (LCOE) / Net Present Value (NPV) analysis to assess the economic impact of the two technologies on developers, owners, financiers, and insurers of utility scale solar power plants.

The TÜV report also highlighted the below benefits of Array’s tracking technology:
• 7% lower LCOE (Levelized Cost Of Energy)
• 4.5% higher NPV (Net Present Value)
• 15% lower scheduled O&M cost
• 130 × lower unscheduled O&M cost
“At TÜV Rheinland, we pride ourselves on unbiased and high-quality research and reporting,” said Mark Skidmore, Regional Field Manager, Solar-North America of TÜV Rheinland. “We routinely put technologies across the solar tracker industry through rigourous testing to challenge the industry’s biggest players to go above and beyond with the reliability of their designs. Together, we can sustainably grow the global solar tracking market.”
