Thermography on photovoltaic systems
TESTOsolutions
Quick and efficient. You can now easily monitor photovoltaic systems ofall sizes in a way that is wide-ranging, contactlessand exceptionally efficient. This is because theaccurate thermal imagers from Testo are able todetect malfunctions and ensure that all componentsfunction smoothly, ensuring maximum cost effective -ness. The option of inputting solar radiation intensityoffers you extra reliability and afterwards you willknow exactly, what you have measured.

Thermography on photovoltaic systems We measure it.
Risks in operating photovoltaic systems.
Faults that occur when operating photovoltaic systems can be quicklydiagnosed from a solar radiation of 500 – 600 W/m² via markedchanges to the thermal properties using Testo thermal imagers:
Defective bypass diodesContact faults and short circuits in solar cellsPenetrated humidity, contaminationCracks in cells or in the module's glassNon-functioning or disconnected modulesSo-called mismatches, i.e. loss of performance due to different capacities of individual modules
In thermographic measurement, it is important that you note theintensity of the solar radiation. This is because values that are too lowdistort the results.
The application
The solution
The testo 876, with its flexible camcorder design, enables you to detectpower losses in your photovoltaic system while in operation really easilyand efficiently. You always have the right image section in view thanksto the large rotatable display and optional telephoto lens. Its specialfeature: you can enter the solar irradiation data in W/m2 into the cameravery easily using the solar mode. No need to worry any more about
losing the data, this is stored for each thermal image and is availablefor analysis in the evaluation software. Which means that using onlyyour thermal imager, you can guarantee the operational security of yourphotovoltaic system, demonstrate utmost efficiency and haveeverything completely under control.
