Electrical and Solar Power System Integration

The contract entails the installation and integration of fully self-sustaining solar-powered electrical systems for each stream gage located across California, requiring the procurement and deployment of solar panels, deep-cycle batteries, charge controllers, and weatherproof wiring, all housed within durable, sealed enclosures designed to withstand extreme environmental conditions. The work must ensure continuous, reliable power delivery to remote monitoring equipment without grid dependency, adhering to strict durability and performance standards suitable for outdoor, unattended operation in varied geographies and climates. The subcontract falls under NAICS code 238210 for electrical contractors and is issued by the California Department of Water Resources with a posting date of June 16, 2026. Though specific locations are not detailed, performance is expected across the state’s network of stream gage sites. The project emphasizes complete system integration with no external power sources, necessitating precise engineering for energy efficiency, battery longevity, and surge protection. All components must be selected for minimal maintenance and maximum resilience, ensuring uninterrupted data collection for hydrologic monitoring in California’s diverse and often remote watersheds.
