San Diego, CA
Marten Transport is a premier asset-based temperature-sensitive truckload carrier, providing world-class logistics and transportation solutions across North America. Operating a high-capacity terminal in Otay Mesa, San Diego—a critical hub for international trade—requires a massive, 24/7 infrastructure, including expansive cold-storage facilities, sophisticated fleet maintenance bays, and comprehensive administrative suites. In January 2024, Marten Transport partnered with Stellar Solar Commercial to implement a high-performance 42.24kW (DC) solar strategy, transforming its industrial rooftop into a sustainable energy hub that supports its mission of logistical excellence.
Designing a solar solution for a high-volume transportation terminal requires a sophisticated understanding of heavy-industrial electrical loads and long-term hardware durability. Stellar Solar Commercial engineered a robust rooftop system designed to maximize energy production within the terminal’s footprint, utilizing advanced bifacial technology to harvest more energy per square foot.
The technical architecture of the Otay Mesa Marten Transport installation features:
-88 Hanwha Q.Cells Q.PEAK DUO XL-G10.3/BFG 480W Modules: These high-density, 480W bifacial modules represent the cutting edge of monocrystalline solar technology. By capturing sunlight from both the front and the back of the panel, these 88 modules “boost” total energy yield, providing a consistent and powerful stream of clean electricity.
-Optimized SolarEdge Inverter Configuration: To manage the industrial power conversion with maximum efficiency, we utilized two SE17.3KUS SolarEdge inverters. This system, paired with panel-level power optimizers, ensures that every single module performs at its individual peak, eliminating losses from shade and providing granular, module-level monitoring.
-Strategic Industrial Offset: Placed into service on January 10, 2024, this massive 42.24kW array was precisely engineered to neutralize a significant portion of the terminal’s daily electrical load, shielding the company from the volatility of the commercial energy market.
For a global transportation leader in the 2026 energy landscape, where Southern California utility rates for industrial and cold-storage facilities have reached historic highs, the transition to solar is a mission-critical double victory. By generating its own power on-site, Marten Transport has effectively locked in its energy costs for the next two decades.
Every kilowatt-hour produced by the bifacial Hanwha array is a kilowatt-hour the company does not have to purchase from the utility at premium peak rates. This creates a permanent stream of capital savings that can be redirected toward:
-Fleet Modernization: Funding the transition to the next generation of temperature-controlled trailers and fuel-efficient tractors.
-Terminal Enhancements: Investing in advanced automated systems for logistics and cold-chain management.
-Global Competitiveness: Protecting the company’s bottom line against future utility inflation for the next twenty years.
Since 1998, Stellar Solar Commercial has been the preferred partner for California’s most technically demanding manufacturing and logistics hubs. We bring over 28 years of technical expertise to these high-stakes projects, navigating the unique structural and electrical requirements of industrial buildings while ensuring that 24/7 logistics operations remain undisturbed during the construction phase.
Our in-house team handles the entire lifecycle of the project—from initial structural analysis and electrical load profiling to navigating complex utility interconnection and state-specific incentive programs for large-scale commercial entities. We specialize in “quiet-professional” construction, ensuring that the facility’s schedule and safety remain the top priority throughout the project.
As we move through 2026, the strategy for premier logistics centers has evolved to include Solar + Battery Storage. For organizations like Marten Transport, adding a utility-scale battery system provides an essential layer of resilience, ensuring that critical data centers, security systems, and high-precision cold-storage controls remain fully operational even during regional power outages or grid instability.
Stellar Solar Commercial continues to lead this energy revolution, helping California’s business leaders build a resilient, low-cost energy future. We turn logistics rooftops into powerful tools for sustainability and financial success.
