A Technical Report Built for the Owner

A PV Condition Assessment (PVCA) is a structured, documentation-based review of a solar system's technical condition. It is not a sales call. It is not a routine PM visit. It is a formal engineering assessment that produces a written deliverable.

The assessment covers every major system component: electrical, mechanical, thermal, monitoring, and production performance. The output is a written report you can use for insurance, financing, management decisions, or vendor negotiations.

NABCEP is the gold standard for solar industry certification. The PVSI credential is specifically for inspection professionals, not installers.

What the Written Report Covers

Delivered within 5 business days of the site visit. All findings documented with photographic evidence.

01: Electrical Integrity

  • DC termination torque and condition
  • MC4 connector condition and weatherproofing
  • Grounding conductor continuity and connections
  • Conduit and wiring management
  • Labeling compliance and circuit identification
  • Combiner box and disconnect condition

02: Thermal Imaging

  • Full array infrared scan during active production
  • Hot cell identification (cracked cells, bypass diode failures)
  • DC combiner and terminal block thermal review
  • Inverter heat management assessment
  • Delta-T classification per IEC 62446-3 reference ranges

03: Structural & Roof Interface

  • Racking hardware and fastener condition
  • Roof penetration and flashing condition
  • Array drainage: standing water risk points
  • Corrosion and weathering assessment
  • Panel condition: visible physical damage, soiling

04: Performance & Monitoring

  • Production vs. modeled output comparison
  • String and optimizer performance analysis
  • Monitoring platform configuration review
  • Alert history and communication gap analysis
  • Inverter event log review

05: Inverter & Component Lifecycle

  • Inverter model and production year
  • Estimated remaining design life
  • Warranty status: original, extended, expired
  • Firmware version and known issue review
  • Capacitor replacement considerations (electrolytic inverters)

06: Recommendations

  • Findings prioritized by severity (immediate / near-term / long-term)
  • Specific repair and maintenance recommendations
  • Array cleaning interval recommendations based on observed soiling
  • Cost-impact analysis for major findings
  • Suggested follow-up actions

When Building Owners Commission an Assessment

Unexplained production decline

Your monitoring shows lower output than expected and your O&M provider's explanation doesn't satisfy. An independent assessment finds the actual cause.

Property acquisition

You're buying a building with an existing solar lease or ownership arrangement. Know what you're inheriting before closing.

Portfolio refinancing

Lender or insurer requires a technical review. We provide written documentation acceptable for commercial financing.

O&M contract renewal

Evaluate your current O&M provider's performance with objective data before renewing or switching.

System age milestone

5 years, 10 years, or approaching inverter warranty expiration. Structured review identifies risks before they become failures.

Insurance claim documentation

Storm damage, rodent damage, or other casualty event. Independent assessment documentation supports the claim.
