Arizona-based solar innovator Erthos and Texas developer Sky Community Solar have finalized a master agreement to deploy a 180-megawatt community solar portfolio across Texas. The deal, signed in early April 2024, leverages Erthos’s ground-breaking technology to bring clean energy to sites located near the state’s major urban centers.
At the heart of the agreement is Erthos’s Earth Mount Solar system, a design that installs photovoltaic modules directly on the ground. This approach bypasses the need for conventional steel tracking structures and driven piles, drastically simplifying the construction and maintenance of solar farms. For San Antonio-based Sky Community Solar, this inherent standardization was a primary factor in the decision, making a single master agreement for the entire multi-site portfolio feasible.
Dudy Levy, a partner at Sky Community Solar, emphasized the unique advantage of this uniform design. “With tracker systems, site-specific factors like row spacing and subsurface conditions cause each site to be unique, making master agreements impractical,” Levy stated. “With Erthos, every site is the same.” This modularity and repeatability across all projects is expected to streamline development and reduce complexity significantly.
The Earth Mount technology also delivers benefits aimed at easing community integration and improving project economics. Its high energy density maximizes land use, while its low vertical profile reduces visual impact—a critical factor in gaining local support. Charles Pimentel, President of Erthos, noted the importance of this community-first approach. “Solar energy has the capacity to enhance lives globally, but it must be implemented in a manner that respects both the land and the residents,” he said. By eliminating costly steel and complex installation for the PV modules, the system also drives down the levelized cost of energy, helping developers optimize their project returns.
“Erthos is an excellent fit for our community solar endeavors,” Levy added. “Their systems are both cost-efficient and unobtrusive, requiring minimal compromise from communities prioritizing clean energy.” The portfolio will consist of individual projects ranging in size from 9 MW to 18 MW. Construction on the first site is scheduled to commence later this year, with the entire 180 MW portfolio projected to be fully operational by the end of 2026.
