TECHNICAL AUDITS

OBJECTIVE

Measure and evaluate the performance of a PV installation during any moment of its life time.
We analyse any specific anomalies, propose solutions and update the yield estimations.

Broken photovoltaic module
Hot spot in photovoltaic module
Dirt effect on photovoltaic modules

PROCEDURE

  • Visual inspection and control during the construction phases.
  • Hot-spot impact measurement: early degradation, individual and operating power losses.
  • Diodes and connecting boxes anomalies.
  • Losses due to potential induced degradation.
  • Equipment ageing analysis.
  • Dust impact on individual and operating power and mismatching increase. Cleaning campaigns planning.
  • Revision and recalibration of the meteorological stations and the operating conditions’ sensor.
  • Monitoring system validation.
