Thermography for photovoltaic installations

Even small errors can have a major negative impact on efficiency.

The best method for checking photovoltaic installations is thermography, which uses a thermal camera to record the temperature distribution across the solar cells. This allows faults and defects to be detected in good time, maximizing the profitability of the plant. In the guide and checklist below, you will find valuable information on thermography for PV installations and practical tips for carrying out inspections with a thermal imaging camera.

Checklist for inspections

Photovoltaic installations should be checked after commissioning and regularly throughout their lifetime.

Practical guide to solar thermal imaging

Practical guide

To make it easier for our customers, we have developed a practical guide for thermography of photovoltaic installations.

Developed for your measurement tasks. And to save valuable time and money.

Preventing costly malfunctions and deficiencies is essential in energy production and especially when it comes to energy distribution. With the help of a thermal camera from Testo, you can quickly and easily detect and analyze thermal irregularities. It ensures efficient production and good delivery security.

For photovoltaic installers

  • Carrying out thorough inspections of large photovoltaic installations
  • Quickly detecting thermal anomalies
  • Ensure optimal, efficient operation
  • Ensuring permanent energy distribution

Heating systems and leaks

Heating, ventilation and air conditioning systems can be effectively inspected using a thermal imaging camera. A quick look with the Testo camera is enough to easily detect anomalies:

  • Heat pipes can be located in a non-contact way
  • Installations can be quickly checked
  • Heating systems can be monitored in a safe way

The thermal imaging camera helps you quickly trace heating pipes and find water leaks without having to break up large sections of floor or wall. This saves time and costs. It also avoids making homes and workplaces inaccessible for long periods of time. Read our practical guide!

Inspection in electrical installations

Incorrect electrical connections or overloads in switching systems, power distribution units and electric motors can lead to costly downtime or even fire damage. About 35% of all fires in industrial companies can be attributed to severely overheated electrical components. If a conductor, a cable or a fuse is defective or if individual components malfunction, this leads to increased transmission resistance and thus unusual heat generation.

Regular inspection of all electrical installations using a Testo thermal imaging camera helps to minimize the risk of breakdowns. This enables immediate detection of both existing faults and potential sources of faults and hazards. An additional advantage of thermography is that in many cases it can be carried out during operation.

Energy efficiency in buildings

Energy efficiency in buildings is becoming increasingly important with ever-rising energy costs. IR measurement with a Testo thermal imaging camera is excellent for quick and efficient detection of energy losses. Possible causes could be, for example:

  • Cold bridges in ceilings, walls and balconies
  • Defective or missing insulation
  • Leaking windows or doors

All problem areas on an exterior wall are visualized in detail in the thermal image. This means you can quickly find errors, easily assess any energy losses and present the measurement results to decision-makers in an understandable way.

Energy efficiency of technical systems

In technical installations, energy efficiency is also becoming increasingly important. Typically, energy consumption for machinery and piping in manufacturing companies is actually significantly higher than for ventilation systems in buildings. Experience shows that there is great potential for energy savings.

  • In steam and hot water pipes
  • In cold rooms and ceilings
  • When using process heat

With a Testo thermal imaging camera, you can quickly and easily detect problems, as poorly (or not at all) insulated places are immediately visible in a thermal image. Bottlenecks in clogged heating systems also become clearly visible and can be addressed in a targeted way.
