5.62 MW DC | 8,640 Panels | Tracker (SFR) | EPC | D2C
Following the successful completion of Phase 1, Double J Dairy returned to RSI to expand its on-site solar capacity with a second, larger system. Phase 2 brought the total installation to over 10 MW across the facility. As with Phase 1, RSI self-performed all civil, electrical, and construction work under a single EPC contract.
Scope of Work
- Full EPC delivery: engineering, procurement, and self-performed construction
- Single-axis tracker (SFR) system installation across a 5.62 MW site
- Medium voltage electrical work
In-house permitting, utility interconnection, and zoning management
- Civil site work and electrical pad construction
- QA/QC, OSHA compliance, and project management throughout
Approach
Expanding an existing solar facility introduces coordination challenges that greenfield installations don’t. Phase 2 required careful integration with the operational infrastructure already in place from Phase 1, while keeping the dairy’s active operations running without disruption. RSI’s in-house team managed all sequencing and utility coordination, ensuring a clean handoff between phases and a system that performs as a unified whole.
8,640 panels across over five and a half megawatts demanded the kind of disciplined project management and safety oversight that RSI built its reputation on across large agricultural sites throughout California.
Results
Phase 2 delivered an estimated $1.21M in annual energy savings with a projected payback period of 3.2 years and a 31.3% ROI, expanding one of RSI’s flagship agricultural installations into a 10+ MW facility that stands as a long-term model for large-scale dairy solar in California.
