Acceptance inspection and testing

For solar commissioning we carry out the inspections, electrical measurements and tests the project's scope calls for, and give acceptance a basis.

Get in touch

At commissioning we carry out the tests within IEC 62446 on site: I-V measurements, thermal inspections and visual inspections.

How we work

Our solar inspection services are delivered as an accredited Type A inspection body, independent of the plant's designer, suppliers and contractor. We report each test with its standard and the accreditation scope of the activity it belongs to.

Get in touch

Visual inspection
We inspect the plant visually within IEC 62446-1.
I-V measurements
Through IV curve testing we measure and assess the current-voltage (I-V) curves of the strings.
Thermal inspection
We carry out the plant's thermographic inspection within IEC TS 62446-3. Thermal imaging of the solar panels, often as a drone solar inspection, covers the whole plant.
Battery integration checks
In BESS commissioning on storage and hybrid projects we check the integration with the battery system, the connections and the energy flow.

What we deliver

Our deliverables are set by the scope of each job; we do not hand over the same report package on every project.

The scope of the tests
We state which inspections and tests were carried out on which parts of the plant.
The methods used
We give each test's method, its standard and its place in our accreditation scope.
The measurement results
We present the measured values with the measurement conditions and the instruments used.
A technical assessment
We explain what the results show for acceptance, and the non-conformities we found.
