With Stem, SunGreen Delivers Higher Value Solar + Storage Solutions

Southern California-based SunGreen Systems offers commercial solar PV, energy storage, LED lighting, and cool roof systems. With roots in real estate development, the 10-year-old firm has the knowledge and experience to handle large commercial solar plus storage construction projects.

​​Over the last few years, SunGreen has focused on solar super structures on parking garages. The company recently installed a 400kW solar parking garage in Irvine, and it is currently completing a 1MW solar parking garage at Irvine’s Atrium Building. To deliver more value to customers at lower costs, SunGreen continues to seek out new technologies and strategies, partnering with industry-leading firms such as Stem.

Challenge

Changes in the utility industry can mean that expensive, on-peak rates don’t align with the sunniest part of the day, when solar is most effective. ​This means less savings for companies with standalone solar systems that must rely on utility power in the evenings.

Solution

As a turnkey energy storage provider, Stem supports SunGreen throughout all phases of the project lifecycle. A key benefit is Stem’s procurement expertise and buying power: Stem can negotiate a better price on batteries and then warehouse the batteries to ensure on-time delivery to job sites.

Results

SunGreen’s Stem-powered solar + storage strategy has led to accelerated uptake by customers. Project payback for customers has improved by 6-12 months compared to standalone solar projects, while the increased customer savings has resulted in higher SunGreen revenues.

Alex Deeter

Sales & Marketing Engineer​, SunGreen Systems

“Many businesses are worried about how changes in the utility industry will impact their solar investment. Thanks to Stem, we are able to offer our customers a solar + storage strategy that ensures they can easily adapt to these shifts and continue to derive optimal value from their solar projects.”
