Tech Startup Edisun Claims World’s Largest Rooftop Solar Tracker Installation

Edisun Microgrids Inc., a solar technology company created at technology incubator Idealab, is determined to prove that trackers aren’t just for ground-mount projects anymore and has claimed “the world’s largest rooftop tracker installation.”

The California-based startup first introduced its PV Booster dual-axis rooftop solar tracker last September, and now Edisun has announced a strategic partnership with West Hills Construction Inc., a California-based design/build general construction firm, to develop up to 20 MW of commercial and industrial (C&I) rooftop solar projects utilizing the PV Booster product.

The first project developed under this partnership is a 1 MW solar array installed on 368,000 square feet of a 528,000 square-foot cold storage industrial building in Oxnard, Calif. Edisun says the project utilizes more than 2,900 PV Booster trackers, making it the world’s largest rooftop tracker installation.

This installation is financed and owned by Harry Ross Industries (HRI), the owner of the building. The solar power generated by the PV Booster installation will benefit HRI’s tenant, Chiquita Brands International.

Edisun says its PV Booster is a dual-axis rooftop solar tracker specifically designed to meet the needs of C&I building owners and solar developers. By tracking the sun throughout the day, PV Booster increases energy production by 30% and enhances project economics by 20% when compared to conventional fixed-tilt installations, according to the company.

Edisun further claims that with a low-profile, high-strength design, PV Booster renders the wind a non-issue. The product features flexible layout design options, minimal weight per square foot, and fast and easy installation and operations and maintenance, while also meeting strict safety standards, the company adds.

“The West Hills team is dedicated to finding and implementing technologies that meet our impeccable standards for craftsmanship while improving our customers’ bottom lines,” says Rusty Wood, vice president of West Hills Construction Inc. “Over the last decade, we have explored numerous solutions that promise to optimize rooftop solar at the commercial and industrial scale.”

“We are longtime supporters of solar energy, both for its environmental and economic benefits,” says Robert Ross, managing partner of HRI. “The addition of PV Booster technology to our Oxnard facility made sense for a number of reasons, in particular because it required less investment to get the same output as a stationary system. It’s also vitally important to HRI that we provide the most environmentally friendly facilities to our tenants. We are confident that we’ve accomplished this mission by deploying Edisun’s cutting-edge technology.”

“From responsible water management to the adoption of renewable energy, environmental stewardship has been a key pillar of the Chiquita business for decades,” says Andrew Biles, president and CEO of Chiquita Brands International. “Going solar at our Oxnard facility helps us directly achieve our corporate sustainability goals and meaningfully strengthens our leadership position among environmentally conscious global organizations.”

“Partnering with a visionary company such as West Hills, which has built more than 10 million square feet of real estate and is an expert in construction and solar installation, is the first of many exciting growth milestones for Edisun,” says Bill Gross, CEO of Edisun Microgrids and founder of Idealab. “PV Booster’s technology fundamentally improves the economics of rooftop solar for developers, installers, building owners, and tenants, which aligns with our core mission to revolutionize the economics of solar. We believe this increase in the value of solar projects, such as Chiquita’s Oxnard installation, will be the catalyst for the widespread adoption of solar in the C&I sector.”
