Paving the way for other affordable and scalable projects across the US

TDP Single-Axis Solar Trackers Installed in Colorado Community Solar Project

The project is sited on a former landfill provided by Larimer County, adjacent to transmission lines, and has two terraced planes, calling for an upper and lower array. Solar FlexRack’s engineering team was on-site during foundation and tracker construction and responded quickly to resolve issues with the site’s rocky substrate and to streamline tracker installation.

Typically, installers would trench for wiring; however, to reduce time and costs, the project transitioned to suspended cabling. Streamlined project management and tight coordination enabled GRID’s team to install over 6,000 modules in just 2.5 weeks.

GRID Alternatives (GRID), working closely with the Colorado Energy Office and Poudre Valley Rural Electric Association (PVREA), developed a 1.95 MWdc community solar project on the southwest side of Fort Collins, Colorado. The project is the eighth community solar project installed as part of a statewide initiative to demonstrate scalable models for electric cooperatives to broaden the reach of solar energy and reduce energy costs for low-income households.

Coyote Ridge will serve a variety of off-takers, with 1.2 MW of the plant’s capacity dedicated to low-income households, affordable housing providers and nonprofit organizations through PVREA’s community solar subscription program. Individual subscribers expect to save 30% or more on their monthly electricity costs.

Under GRID’s community participation and workforce development model, job trainees, volunteers from the community and employees from the utility came together to work alongside GRID staff in the construction of the PVREA project. Even with this diverse crew, the entire installation took just under 60 days.

Volunteers install modules in Colorado community solar trackers project.

PVREA’s Coyote Ridge Community Solar Project had a hard stop for project completion. To take advantage of specific wholesale rates and reap the financial benefits that made the project viable, the team needed to complete the contract by the end of September. Through effective and flexible management, GRID completed the project as agreed.

The Only Solar Tracker Solution with Full Design, Installation, & Commissioning Services to reduce risks and costs. From preliminary layout and design, through geotechnical engineering, construction and commissioning, and for the life of the system, TDP Turnkey Solar Trackers provide a reliable solution that reduces installation time and cuts operations and maintenance costs.

TDP Solar Trackers have no mechanical components between rows, allowing easy access for mowers, cleaning services and other project maintenance.

TDP Solar Trackers can be programmed based on the terrain, to optimize MWh production. A solar tracker on an east-facing slope gets more early-morning sun, and a solar tracker on west-facing slope gets more in the late afternoon, increasing the plant’s overall energy yield.

Solar FlexRack, a division of Northern States Metals, is an integrated solar company that offers custom-designed, fixed tilt ground mount and single-axis solar tracking systems in the commercial and utility scale, solar mounting industry.
