Why should PV thermography be done?

  • Only less than 20% of all PV systems are performing optimally and without errors – the rest have defects that cause power and, therefore, income losses!
  • Just one defected diode of a 30 kWp PV-system does not only lead to a more than 100€ loss of earnings annually, but may also cause damage to the nearby lying panels
  • You’ve noticed that the PV system does not perform as efficient as before but you can neither identify the reason or localize the problem
  • Following a cleaning or maintenance session, you want to see a "Before & After" state of your PV system to know how to optimise the system further

What are the advantages of PV thermography?

  • Thermography is a perfect means to identify damages that stay invisible to the naked eye
  • Get a good return on your investment by getting the whole picture of the potential repairs: Prevention is better than cure!
  • Make your PV system understandable for the cleaners and technicians who work with it
  • A quick, cheap and thorough alternative to the on-site technical inspection

What clients say about us

Kunde 1
I couldn’t believe how many defects were spotted on my PV system. And this just after one year in operation!
Ines Hahn from Klotingen
Kunde 2
It has been such a great tool to boost my earnings! After the themographic check I knew exactly what I had to do. It brought us 8% increase in profits!
Maximilian Vogler from Piccione

FAQ

Over time many PV systems are losing a great part of their initial efficiency: single cells break down, important components such as inverters do not operate properly and so on. Besides reducing the yield of the system, such faults can also cause further damages to the PV system and even lead to a fire. Thermographic check allows you to define and locate these problems due to their thermal signature.
The thermal camera converts heat (infrared radiation), emitted by the PV panels, into colour images. These colour images allow us to see even the minor differences in temperature. This allows to carry out a quick diagnosis of the PV system. Defective diodes, assembly faults, inactive cells and moistures are then analyzed and defined on a thermal image.
It depends on such factors as accessibility, size and type of the PV system.
As a rule of thumb you can use:

• Immediately after the installation: to ensure its efficiency right from the start
• Every two years: to ensure its optimal performance over time
• At the end of the warranty period: to save money in case any repairs are needed
At least the following defects are detected:

a. Defective modules
b. Defective substrings
c. Defective cells
d. Defective inverters
e. Potential Induced Degradation (PID)
f. Hotspots
No, cameras used for the thermographic analysis do not eradiate. Basically, this is just a normal camera with a different type of sensor.
The cost of a thermographic check depends on several attributes. Factors such as size, type of the system, degree of slope and accessibility determine the price here.
