After the testing of the PV generator, the functionality of the other system components and their joint functionality must be checked and tested. This testing step should follow the same principles as the preceding PVP acceptance test. At least the following should be tested:
Measurements are usually carried out “from head to tail”, starting with the release of the water into the supply line (to storage tank or direct injection) and ending with the flushing outlets of the irrigation pipes. Pressure measurements have to be taken at all system joints / distribution knots to assess the hydraulic distribution in all sections. These measurements have to take into account the pressure variation during the day caused by fluctuating irradiance levels. The results need to be documented as a hydraulic profile of the irrigation system.
Considerable differences between the designed and actual performance can be a sign for a poor design (collected data, poor choice of component, etc.) or poor workmanship. Quality of workmanship has a direct influence on system performance and sustainability, and poor workmanship can compromise even the best system components. The tool SET UP – Workmanship Quality Checklist comprises various workmanship indicators clustered into different categories. The purpose is to assess whether quality of installation adheres to best practices, safety requirements and overall installation sustainability.
