High-resolution drone thermography with AI-supported issues analysis<\/strong>
With our photovoltaic thermography, you secure the performance, safety, and long-term value of your PV system.<\/p>\n

Through high-resolution drone imaging and AI-supported thermal analysis, we make issues visible that remain hidden during normal operation and can lead to significant yield losses or safety risks. Our interdisciplinary team of experts evaluates all anomalies according to standards, assigns them to specific modules, and provides concrete recommendations for action along with economic impacts.<\/p>\n

This provides you with a reliable basis for repairs, warranty processes, investment decisions, or the sale of your system.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n

\n
\n

Photovoltaic thermography during commissioning<\/h3><\/div><\/div><\/div>\n\n

For new ground-mounted PV systems, we use drone thermography to verify that all modules and strings are functioning properly. Hotspots, cell cracks, or faulty connections are detected before the system is commissioned. This ensures full system performance from the outset and establishes a reliable basis for warranty and guarantee processes. <\/p>\n<\/div><\/div>\n<\/div>\n\n

\n

Photovoltaic thermography for existing systems<\/h3><\/div><\/div><\/div>\n\n

For existing systems - for example, before purchase or sale, after repowering measures, or as part of operations management - drone thermography serves to establish an objective status quo. It reveals technical weaknesses, performance losses, and potential optimization opportunities. For you, this means: well-founded decision-making bases, investment security, and the ability to initiate targeted measures for yield enhancement or repair.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

When<\/span> is photovoltaic thermography generally advisable?<\/h2>\n<\/div><\/div>\n<\/div>\n\n
\n

To verify module performance<\/h3>

With drone thermography, you can identify early whether individual modules or strings exhibit hotspots, cell damage, or defects, even before they lead to yield losses.<\/p>\n<\/div><\/div>\n\n

To secure service life and preserve value<\/h3>

You identify technical weaknesses in time and can initiate measures to maintain the long-term performance of your system.<\/p>\n<\/div><\/div>\n\n

For well-founded decisions during purchase or sale<\/h3>

Through drone thermography, you obtain reliable information about the condition of your PV system, helping you evaluate purchase prices or justify sales prices.<\/p>\n<\/div><\/div>\n\n

To secure warranty claims and maintenance obligations<\/h3>

With precise results from photovoltaic thermography, you can substantiate warranty claims and plan necessary repairs strategically.<\/p>\n<\/div><\/div>\n\n

For targeted implementation of optimization and repowering measures<\/h3>

You receive a basis for efficiently planning technical adjustments or modernizations of your system to increase yields.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

Typical faults we uncover with drone thermography<\/span><\/h2>\n<\/div><\/div>\n\n

Drone thermography opens a new perspective on your PV system: It enables rapid, large-scale, and precise detection even of remote module areas that are difficult to access during conventional inspections.<\/p>\n

This allows trends in module performance to be identified, potential risks to be detected early, and the condition of the system to be continuously monitored.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n

\n
\n
\"defective-cell-strings-in-thermography-pv-before\"<\/span><\/div>

Cell damage and hotspots<\/h3>

Cell cracks and cell fractures can lead to inactive cell areas and thus to reduced module performance. Hotspots cause severe thermal stress on the module, resulting in failures or even fire hazards. Performance losses of up to 10% are typical. <\/p>\n<\/div><\/div><\/div><\/div>\n<\/div>\n\n

\n
\"defective-cell-strings-in-thermography-pv\"<\/span><\/div>

Defective cell strings<\/h3>

This occurs due to individual inactive cells, connection faults, or failure of bypass diodes. Inactive cell strings become visible through temperature differences in the series-connected cells within a module. This leads to performance losses of 30 to 60% per module. <\/p>\n<\/div><\/div><\/div><\/div>\n<\/div>\n\n

\n
\"Damage<\/span><\/div>

Potential-induced degradation<\/h3>

PID is an effect that leads to gradual performance losses, which after several years can amount to 30% or more. In thermographic images, suspicion of PID becomes visible primarily through a checkerboard-like pattern in the edge area of a string. <\/p>\n<\/div><\/div><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n
