A. Production Analysis

The performance of the realized installation is carefully evaluated according to its specifications and climatic conditions. The performance of the plant is examined with the help of different indicators; performance ratio (PR), specific yield (kWh/kWp), variance based on the weather, individual inverter’s performance, energy performance index (EPI), and plant availability (%). Results are documented with the help of

  • Reports on energy yield.
  • Solar measurements (weather parameters)
  • Operational performance review based on SCADA data (for sites in operations)
  • Provisional acceptance (PAC) and Final acceptance testing (FAC)
  1. Documentation
  • As-built documentation with all the drawings, components, plans, datasheets, declarations and warranties, and final delivery documents for record-keeping and future purposes.
  • Access to the monitoring portal for monthly, semi-annual, and annual assessments.
  • Documentation of all contractual agreements including damages, compensation, response time, preventive and corrective maintenance schedules.
  • Product and performance warranty by the EPC company.
  • Confirmation of the resolved items from the intermediate and final site inspections.
  • Supervision of the commissioning process.

 

Value is added by a detailed solar technical due diligence (TDD) process to mitigate project risks.
