Services
Field Execution. Every Phase.
From first steel in the ground to final commissioning sign-off — Cor Solutions deploys specialized crews for every critical phase of solar PV, BESS, renewable energy, and infrastructure project delivery.
End-to-End Field Coverage
We don't hand off. We stay on-site from mobilization through COD, embedding with your EPC team to close gaps, hit milestones, and protect your schedule. Our crews are OEM-trained, safety-certified, and built for the pace of utility-scale energy and infrastructure work.
Construction Execution
Boots on the ground from day one.
We provide skilled field crews for the full construction phase of utility-scale solar and BESS projects. From civil prep and racking installation to module mounting and wire management — our teams integrate directly with your EPC to keep the schedule moving.
100+ utility-scale projects executed across 20+ US states.
Capabilities
- Racking and tracker system installation
- Module mounting and torque verification
- DC wiring, home runs, and combiner box terminations
- Civil support: trenching, conduit, grounding
- Daily progress reporting and milestone tracking
- Safety compliance and OSHA-aligned site protocols
Commissioning & COD Support
Energize on schedule. Every time.
Commissioning is where projects succeed or stall. Our commissioning crews are OEM-trained on leading inverter and BESS platforms, executing systematic pre-energization checks, string testing, inverter startup, and utility interconnection coordination to get you to COD on time.
9 active sites currently in commissioning or COD phase.
Capabilities
- Pre-energization inspections and punch list resolution
- String-level IV curve tracing and performance validation
- Inverter startup and parameter configuration (SMA, ABB, SolarEdge, Sungrow, Huawei)
- BESS rack commissioning and BMS validation
- Utility witness testing coordination
- COD documentation and as-built support
Troubleshooting & Retrofit
Find it. Fix it. Fast.
Underperforming assets cost money every day. Our troubleshooting teams use advanced diagnostic tools to identify root causes — from module-level faults to inverter failures and communication errors — and execute targeted repairs or retrofits to restore full production.
Rapid deployment — field team on-site within 72 hours of engagement.
Capabilities
- Thermal imaging and EL testing for module defects
- IV curve tracing and shade/soiling analysis
- Inverter fault diagnosis and component replacement
- Tracker malfunction diagnosis and mechanical repair
- SCADA and communication network troubleshooting
- Retrofit execution: inverter swaps, tracker upgrades, restringing
Punch List Closure
Close it out. Clean.
Punch lists that drag past COD erode margins and strain client relationships. We deploy dedicated punch list crews to systematically work through open items — mechanical, electrical, and documentation — so your project closes clean and on time.
Average punch list closure time: under 2 weeks from mobilization.
Capabilities
- Systematic punch list triage and prioritization
- Mechanical corrections: torque, alignment, hardware
- Electrical corrections: terminations, labeling, grounding
- Documentation completion: redlines, as-builts, test records
- Owner walkthrough preparation and deficiency resolution
- Final inspection support and sign-off coordination
O&M Support
Keep it running at peak.
Once your project is live, performance protection becomes the priority. Our O&M support teams provide scheduled preventive maintenance, rapid corrective response, and ongoing monitoring support to maximize energy yield and asset longevity.
Embedded O&M teams available for multi-year site contracts.
Capabilities
- Scheduled preventive maintenance programs
- Corrective maintenance and emergency response
- Module cleaning and vegetation management coordination
- Inverter and tracker preventive maintenance
- Performance monitoring and anomaly investigation
- Long-term O&M staffing and embedded technician programs
