Post-Installation Audit & Optimization Consultancy

Photon Energy Solutions — Independent Audit & Quality Services for Solar PV Systems
(Established 2013)

Why Post-Installation Audit?

  • In Pakistan’s rapidly growing solar market, many PV systems — even expensive ones — suffer from:
  • Design or installation mistakes
  • Poor performance vs. expected output
  • Early degradation & faults
  • Unidentified system losses
  • Safety hazards & non-compliance
  • Warranty claims denied due to poor documentation or hidden defects

Many clients only discover these problems after 1–2 years, when performance starts dropping or ROI fails expectations.

This is why an independent Post-Installation Audit & Optimization by experienced engineers is now critical — especially for:

  • Large industrial / commercial plants
  • Utility-scale solar farms (MW scale)
  • EPCs seeking third-party validation
  • International investors & banks acquiring PV plants
  • Corporate clients preparing for ESG reporting
  • Owners preparing warranty claims or legal action

Objectives of the Audit

  • Verify actual system performance vs. design & contracts
  • Identify hidden faults & quality issues
  • Assess safety, compliance & risk
  • Recommend corrective actions & optimizations
  • Help recover lost generation & ROI
  • Support warranty claims & insurance
  • Build confidence for future investors or asset sales
