Solar PV Technician III

Solar PV Technician III

Location: Roseville / Sacramento, CA Employment Type: Full-Time/On-Site Reports to: Site Manager Pay scale: $38.00 - $40.00 per hour

Clean Energy Services (CES) is an independent, execution-first operations and maintenance (O&M) provider purpose-built to support complex, utility-scale solar, battery energy storage and hybrid assets. Our platform combines dedicated field teams, a 24/7 Remote Operations Center (ROC), and deep operating expertise to reduce operational risk, improve availability, and protect long-term asset value.

This is a large utility-scale solar plus battery storage plant north of Sacramento. The solar side is fixed-tilt racking with 1,500 VDC source circuits feeding string inverters and medium-voltage transformer skids, tied together by a direct-buried 34.5 kV collection system, with met stations across the array. CES runs a dedicated on-site team of PV and BESS technicians, supported 24/7 by our Remote Operations Center.

This is the senior technician seat on the solar side of the plant. You will take faults from first alarm through repair on your own, help the Site Manager plan the PM program, and help bring along the Tech I and Tech II technicians. It is one large plant close to home, with no rotation.
