Job description

We are currently looking for an experienced, motivated, detail-oriented, and tech-savvy Solar Service Technician who can hit the ground running with little additional training needed and become an immediate asset to our team. This position pays 10% commission on all sales, plus hourly.

If you do not have extensive experience in diagnosing and troubleshooting solar systems, please do not apply.

If your background is primarily in installation or roofing (e.g., as an installer or roof lead), this position is not a match. We're looking for someone who can independently manage advanced service calls, warranty repairs, and complex system diagnostics from day one. This is a specialized service role, not an installation position.

Summary/Objective

The Solar Service Technician is responsible for servicing existing residential PV systems. This includes diagnosing inverter and battery faults, processing RMAs, performing component replacements and system expansions, and working with equipment from a variety of manufacturers. The technician will perform testing, commissioning, and routine string testing, as well as complete wiring and torquing of terminations.

While many tasks follow defined procedures, this role frequently requires troubleshooting unfamiliar or complex issues. Service Technicians travel daily to field sites and must be comfortable working independently while interfacing directly with clients.

• Interface with customers to explain findings, options, and next steps
• Complete timely and accurate field reports and documentation
• Follow OSHA safety standards and company-specific PPE requirements
• Maintain company tools, vehicles, and inventory
• Collaborate with team members and support company goals
• Perform additional tasks as directed by leadership

Competencies

• High-level diagnostic and troubleshooting skills
• Ability to communicate technical findings clearly, including over the phone with engineers
• Strong customer service presence and communication
• Self-motivated, organized, and capable of working independently
• Mechanical and electrical aptitude
• Proficient in solar technology, safety requirements, and wiring fundamentals
• Able to follow specific instructions and write clear, detailed field reports
• Comfortable working at heights and on rooftops
• Strong time management and prioritization in a fast-paced service environment
