Your Panels May Have Stopped Producing Even If You Don't See It

Your Panels Might Have Stopped Producing Even If You Don’t See It

Using thermography, it is possible to check whether the module cells meet the quality requirements. In places where high-performance modules are blocked by “poor quality” modules, the correct combination of individual modules prevents incompatibilities. With a check to be made before the end of the warranty period, any problems can be met within the warranty period. Thermography is a non-contact and visual measurement method. Large-surface solar modules can be scanned in a very short time. Thermal irregularities or modules affected by temperature differences are immediately noticed, which are the first indicators of possible failures.

As a result of thermal measurement, you can learn about the following issues;

1. Are there any damaged cells in my solar panels?
2. Is there an unexpected heating in panel materials such as bypass diodes and junction-boxes?
3. Did environmental factors that cause shadowing damage the panels?
4. Are there any strings that have never been activated?

A thermal camera will take photos of your panels. Care should be taken to ensure that the entire panel is within the frame.

Electroluminescence Test of Panels
Electroluminescence (E.L.) test; allows the detection of damages that occur during the manufacturing or assembly of solar panels on a cell basis. This test, which is like an X-ray of the panels, ensures early detection of the parts that show current resistance effect and future problems.

We can obtain information on the following subjects with the electroluminescence test;

• Cell structure.
• Whether there is a fracture etc. in the cells.
• The effects of overhead transportation during EPC installation or whether the panels are stressed.

This test does not give you information about the power of your panel. It can only give information about the source if a problem is currently encountered in the IV curve measurement.

Are Your Solar Panels Really Efficient?

Accurate Results with Thermography and Electroluminescence Tests
You may not always be able to monitor the performance of your solar energy systems. However, your panels may have stopped producing or lost efficiency without you noticing. Therefore, it is of great importance to protect the health and efficiency of your panels with professional testing and analysis methods.

Thermography: Reveal the Hidden Problems of Your Panels
Thermography is an effective analysis method used to check whether the module cells meet the quality standards.

Data to be obtained with thermography:

• Detects whether there are damaged cells in your solar panels.
• Makes it visible whether there is unexpected heating in critical components such as bypass diodes and junction boxes.
• Determines the shading effects that damage your panels.
• Detects unactivated strings.

Since thermography is a non-contact and visual measurement method, it can scan panels located in large areas quickly and efficiently. In this way, possible faults can be detected earlier and necessary solutions can be produced before the warranty period ends.

Electroluminescence (E.L.) Test: X-Ray of Your Panels

Electroluminescence testing is a method used to determine microscopic damage that occurs during the manufacturing or assembly of solar panels. This test, also called the "x-ray" of the panels, provides important information that will extend the life of the panel.

Information obtained with the electroluminescence test:

• Cell structure and health of the panels.
• Whether there are any fractures or microcracks in the cells.
• Damages caused by physical pressure or strain during EPC installation.

This test does not provide information about the instantaneous power of the panels, but it plays a critical role in determining the source of a problem in the IV curve measurement. With the electroluminescence test kit, photos of your panels can be taken and submitted to expert analysis. As a result of these analyses, microcracks and structural defects in the internal structure of the panel are easily detected.

Protect the Performance of Your Solar Panels

You can monitor the performance of your panels with professional thermography and electroluminescence tests, detect potential problems early and take precautions. With these methods, you can minimize energy loss and maintain the efficiency of your system for many years.

Which Solar Energy Systems Projects Provide Better Results?

1. Large-Scale Solar Power Plants (SPP) – Thermography is very useful for quickly and effectively scanning panels spread over large areas. Electroluminescence testing provides detailed analysis on a cell-by-cell basis.
2. Industrial and Commercial WorkSolar Power Plant Projects – Regular inspections of panels installed on the roofs of factories, logistics centers and large facilities are critical for long-term energy efficiency.
3. Individual Solar Power Plant Installations in Residential Areas – Homeowners can benefit from these tests to determine if there is a loss of efficiency in their systems and to resolve issues under warranty.
4. Solar Energy Use for Agriculture and Irrigation Systems – Thermography is an ideal solution to see how panels used in agricultural lands are affected by shading and environmental factors.
5. Solar Panel Manufacturers and EPC Companies – Electroluminescence testing is a critical tool in quality control processes to verify that panels coming out of production and systems made after assembly are working flawlessly.
