PV Solar System Auditing

Technical Solutions provides audit and assessment services for existing solar PV installations — evaluating system health, quantifying performance losses, identifying root causes, and recommending corrective actions to restore or improve energy production.

Service Overview

Solar PV systems can underperform for many reasons — module degradation, inverter faults, shading changes, wiring defects, soiling, or design shortcomings. Without a structured audit, these losses remain hidden and reduce the return on investment throughout the system's life. Technical Solutions conducts thorough field audits using professional diagnostic tools, providing clients with clear, evidence-based findings and actionable recommendations.

Scope of Work

• Visual inspection of modules, mounting structures, cables, connectors, and junction boxes
• Thermal imaging (IR thermography) to identify hot spots, defective cells, and connection faults
• I-V curve tracing for string and module-level performance measurement and comparison
• Inverter performance review — efficiency, fault logs, operating parameters, and communication status
• Electrical system review — protection settings, earthing system integrity, and cable condition
• Comparison of actual energy yield against original design predictions and weather-normalised expectations
• Identification and quantification of performance losses by category (soiling, shading, degradation, faults)
• Prioritised recommendations for corrective action with estimated performance improvement

Deliverables

• System audit report with findings, photographs, and thermal images
• Performance analysis with loss breakdown and quantification
• Prioritised recommendations for corrective action
• Estimated performance improvement and payback for each recommendation
• Executive summary for non-technical stakeholders
