San Diego, CA
IHA Partners, a key player in San Diego’s healthcare and professional services landscape, operates in an environment where precision, reliability, and cost-efficiency are paramount. Managing a high-capacity professional facility requires a massive, constant flow of electricity to power sophisticated IT infrastructure, climate control for sensitive environments, and comprehensive administrative suites. To align their operational strategy with long-term fiscal health, IHA Partners collaborated with Stellar Solar Commercial to transform their facility into a high-performance energy asset.
Designing a solar solution for a premier professional partner requires a sophisticated understanding of commercial electrical loads and structural integrity. Stellar Solar Commercial engineered a robust 202.96 kW (DC) rooftop system tailored to the specific energy profile of the IHA Partners facility.
The technical architecture of this installation features:
-472 Hanwha Q-cells Duo L-G8.2 430W Modules: These high-performance modules represent some of the most reliable technology in the industry. Selected for their superior efficiency and durability, these 472 panels ensure the facility captures maximum energy yield from its available roof space.
-4 SolarEdge 43.2 kW Inverters with Optimized Power: To manage the substantial power conversion, we utilized a distributed configuration of four high-capacity SolarEdge inverters. By pairing these with panel-level power optimizers, the system ensures that every module performs at its peak, providing the granular monitoring and redundant reliability essential for a mission-critical professional environment.
-Substantial Energy Offset: Placed into service on April 2, 2019, this 202kW system was engineered to neutralize a massive portion of the facility’s daily electrical load, shielding the organization from the volatility of the commercial energy market.
For a professional partnership, electricity is a significant and traditionally volatile overhead expense. By generating over 200kW of its own power on-site, IHA Partners has effectively “locked in” its energy costs for decades. In the 2026 energy landscape, where utility rates for San Diego commercial properties have reached historic highs, the foresight of this 2019 installation provides a massive competitive advantage.
Every kilowatt-hour produced by the Hanwha Q-cells is a kilowatt-hour the partners do not have to purchase from the utility at premium “On-Peak” rates. This creates a permanent stream of capital savings that can be redirected toward:
-Technology and Infrastructure: Investing in the latest digital tools and facility enhancements.
-Talent Acquisition and Retention: Redirecting utility savings into the firm’s most valuable asset—its people.
-Operational Resilience: Protecting the partnership against future utility inflation for the next twenty years.
Since 1998, Stellar Solar Commercial has been the preferred partner for San Diego’s leading commercial and industrial clients. Our 28-year history is built on a foundation of technical expertise and a “quiet-professional” approach to construction that minimizes disruption to daily business operations.
Our in-house team handles the entire lifecycle of these 100kW+ projects—from initial structural roof analysis and electrical engineering to navigating complex utility interconnection and state-specific incentive programs. We specialize in working within “live” professional environments, ensuring that business continuity remains the top priority throughout the installation process.
As we move through 2026, the strategy for large-scale professional facilities has evolved to include Solar + Battery Storage. For organizations like IHA Partners, adding a utility-scale battery system provides an essential layer of resilience, ensuring that critical data centers, communication hubs, and security systems remain fully operational even during regional power outages.
Stellar Solar Commercial continues to lead this energy revolution, helping California’s business leaders build a resilient, low-cost energy future. We turn commercial rooftops into powerful tools for sustainability and financial success.
