Testo thermography of photovoltaic and solar

  1. 1. TI_Photovoltaic_MASTER_I_2012 30.11.2011 16:58 Seite 1 We measure it. TESTOsolutions Thermography on photovoltaic systems Quick and efficient. You can now easily monitor photovoltaic systems of all sizes in a way that is wide-ranging, contactless and exceptionally efficient. This is because the accurate thermal imagers from Testo are able to detect malfunctions and ensure that all components function smoothly, ensuring maximum cost effective- ness. The option of inputting solar radiation intensity offers you extra reliability and afterwards you will know exactly, what you have measured.
  2. 2. TI_Photovoltaic_MASTER_I_2012 07.12.2011 07:28 Seite 2 Thermography on photovoltaic systems We measure it. The application Risks in operating photovoltaic systems. Faults that occur when operating photovoltaic systems can be quickly diagnosed from a solar radiation of 500 – 600 W/m² via marked changes to the thermal properties using Testo thermal imagers: Defective bypass diodes Contact faults and short circuits in solar cells Penetrated humidity, contamination Cracks in cells or in the modules glass Non-functioning or disconnected modules So-called mismatches, i.e. loss of performance due to different capacities of individual modules In thermographic measurement, it is important that you note the intensity of the solar radiation. This is because values that are too low distort the results. The solution Thermography with Testo: easy, quick and reliable. The testo 876, with its flexible camcorder design, enables you to detect losing the data, this is stored for each thermal image and is available power losses in your photovoltaic system while in operation really easily for analysis in the evaluation software. Which means that using only and efficiently. You always have the right image section in view thanks your thermal imager, you can guarantee the operational security of your to the large rotatable display and optional telephoto lens. Its special photovoltaic system, demonstrate utmost efficiency and have feature: you can enter the solar irradiation data in W/m2 into the camera everything completely under control. very easily using the solar mode. No need to worry any more about More info. Tel: 01420 544433 0981 8484/Q/01.2012 Email: info@testo.co.uk Web: www.testolimited.com
