The technical assurance of a solar power plant rests on it being independently inspected from construction through to operation. This page sets out how the inspection and verification activities within our accreditation scope proceed on site.

When this process is completed, all the details of the project, return, costs, expected productions related to the ges project are determined.

1 – Construction Phase

This stage covers the inspection activities carried out during the construction period.

The projects and products submitted at this stage are verified against both the specifications and the relevant IEC standards, and the findings are reported.

With the start of the field processes, the part we call employer engineering in solar power plants in the field begins. The personnel in the field regularly inspect the productions. All activities are reported daily and weekly. Regular meetings are held with the contractor to reduce the occurrence of problems.

At this stage, our biggest goal is to prevent irreversible problems with our experience and knowledge.

Accredited IEC62446 acceptance tests begin when the plant is completed.

At this stage, the performance of the solar panels is inspected and examined for thermal faults. The site is reviewed in general and any improvements that can be made are realized. When the tests are completed, an accredited report is submitted by the accredited ges audit company within the scope of IEC62446. These reports can be considered as the acceptance criteria of photovoltaic modules and the system. With this report, the construction phase is completed and the operation phase begins.

2 – Operation Period / PR Verification / Periodic Tests

In this section, the performance of the products and system after the construction period is regularly inspected according to IEC61724 standard.

At this stage, we work together with the remote monitoring system and the radiation/production/temperature data from the system is uploaded to the verification software. This software compares the actual and simulated values for the relevant time zone and tells us whether the system is operating at optimum performance or not. Thus, we have information about whether the system is working efficiently or not and detailed analyzes are carried out in the system within this information. The performance of solar energy systems is calculated with IEC61724.

PR verification is repeated periodically and the results are reported.

This way, the performance of the system can continue to be checked on a regular basis. If you would like to learn more about precision PR calculation, please click here.
