Performance
Compare field conditions and system behaviour using the measurements appropriate to the question.
Focused field testing
Clear evidence for better maintenance decisions
Select the test that matches the condition you need to investigate. We document observations and measurements, then explain the practical next steps.
Why inspection matters
Different measurements answer different questions.
A useful inspection begins with the system, operating condition and concern. The scope should follow that question—not a fixed checklist.
Possible outputs include recorded measurements, visual observations, identified follow-up items and practical maintenance priorities. Testing does not create unsupported certification claims.
Electrical
Review accessible connections, insulation and grounding conditions within an agreed test scope.
Safety
Identify observations that warrant maintenance, isolation or further specialist investigation.
Environmental
Record irradiance, temperature and site conditions that influence how results are interpreted.
Commissioning
Document selected checks and measurements to support an organised system handover.

Choose the evidence your decision needs.
Each test page explains what is measured, how the field work is approached and how results should be interpreted.
01
Thermography
Infrared thermography helps identify unusual temperature patterns across solar modules, terminations and accessible electrical equipment while the system is operating under suitable conditions.

02
Irradiance Test
On-site irradiance measurement records the solar energy reaching the array during the test period and helps place other observations in the right environmental context.

03
Grounding/Earthing Test
Grounding and earthing tests help assess whether accessible parts of the system have the intended connection to earth and whether measured resistance warrants further attention.

04
Insulation Test
Insulation resistance testing checks suitable de-energised circuits or components for leakage paths that may indicate damaged, contaminated or deteriorated insulation.
