• Mechanical QA/QC inspection

• Full system startup & performance validation

• Monitoring & communications setup

• Utility witness testing & AHJ coordination

• Detailed commissioning reports & documentation packages

We don’t just energize systems — we validate performance and protect long-term asset value.

REPOWERING & SITE REMEDIATION

For aging or underperforming systems, we provide turnkey repowering and modernization solutions.  We assess existing infrastructure, identify performance gaps, and implement strategic upgrades to restore reliability, improve production, and ensure current code compliance.

Services include:

• Inverter and module replacement

• Array reconfiguration & structural remediation

• Conductor and combiner upgrades

• Interconnection & protection updates

• Code compliance corrections

• Full recommissioning after upgrades

We help asset owners extend system life and maximize return on investment.

PREVENTATIVE MAITENANCE

Proactive maintenance protects performance and reduces risk. Our preventative maintenance programs are designed to identify issues early, maintain warranty compliance, and provide clear performance documentation.

Services include:

• Electrical & mechanical inspections

• Thermal imaging & insulation resistance testing

• IV-curve performance validation

• String-level diagnostics

• Grounding & bonding verification

• Monitoring performance audits
