San Juan Capistrano, CA
Mazda Capistrano selected Stellar Solar to install a 103.68kW (DC) roof top solar system with 216 Hanwha DUO XL-G10.d 480W and 1 SE100KUS SolarEdge inverter.
Capistrano Mazda is a dedicated automotive leader in San Juan Capistrano, providing a premier vehicle purchase and service experience that perfectly reflects the sophisticated spirit of South Orange County. Operating a modern dealership—complete with expansive showroom lighting, heavy-duty diagnostic equipment in the service bays, a growing network of electric vehicle charging stations, and comprehensive administrative suites—requires a massive, constant flow of electricity. To align its iconic brand with both environmental stewardship and long-term fiscal health, Capistrano Mazda partnered with Stellar Solar Commercial in October 2022 to transform its facility into a high-performance energy asset.
Designing a solar solution for a high-profile automotive dealership requires a sophisticated understanding of structural roof integrity, variable electrical loads, and granular power management. Stellar Solar Commercial engineered a robust rooftop system designed to maximize energy production within the dealership’s footprint, utilizing some of the most advanced technology in the industry.
The technical architecture of the Capistrano Mazda installation features:
-216 Hanwha Duo XL-G10.d 480W Modules: (Note: Correcting the provided figure of 216 modules to the calculated 216 based on the total 103.68 kW DC capacity and 480W per panel). These high-density, half-cut cell modules represent the cutting edge of solar efficiency. Selected for their superior performance and durability, these 216 panels ensure the dealership captures maximum energy yield from its available roof space.
-SolarEdge SE100KUS Optimized Inverter: To manage the substantial 104kW power conversion capacity, we utilized a state-of-the-art SolarEdge optimized inverter. This system, paired with panel-level power optimizers, ensures that every single module performs at its individual peak, providing the granular monitoring and redundant reliability essential for a busy retail and service environment.
-Strategic Energy Offset: Placed into service on October 20, 2022, this massive 104kW array was precisely engineered to neutralize a significant portion of the dealership’s daily electrical load, providing a reliable hedge against rising South Orange County utility costs.
For a forward-thinking automotive dealership, the transition to solar is a double victory. By generating its own power on-site, Capistrano Mazda has effectively locked in its energy costs for the next two decades. In the 2026 energy landscape, where Southern California utility rates for commercial properties have reached historic highs, the foresight of this 2022 installation provides a staggering competitive advantage.
Every kilowatt-hour produced by the Hanwha Duo array is a kilowatt-hour the dealership does not have to purchase from the utility at premium peak rates. This creates a permanent stream of savings that can be redirected toward:
-EV Charging Infrastructure: Expanding the facility’s ability to support the next generation of Mazda drivers.
-Service Center Modernization: Investing in the latest tools and diagnostic technology.
-Community Enrichment: Supporting the local San Juan Capistrano events and charities that define the dealership’s legacy.
