UV light lamps are indispensable in photovoltaic technology because solar modules must withstand intense stresses daily. Particularly the UV radiation from the sun poses a real challenge for materials and components. This is where a UV light lamp comes into play: with its help, the aggressive UV exposure can be specifically and efficiently simulated. These simulations ensure long-lasting and high-performance solar systems.
Why is UV radiation critical for solar modules?
The sun emits UV-A and UV-B rays in addition to visible light. This UV radiation affects components like films, seals, and coatings over the long term and causes:
- Yellowish discolorations that reduce light transmittance
- Brittleness that leads to breakages
- Detachment of material layers (delamination)
- Reduced performance of the solar module
With the help of a special UV light lamp, these effects can be replicated faster and reliably in the laboratory.
Where is a UV light lamp used in the photovoltaic industry?
1. Material testing and aging tests Manufacturers use UV light lamps to test materials like EVA films or back sheets for their UV resistance. Within a few weeks, you obtain results for which several years would be required in the field. Such tests are conducted according to the strict standards IEC 61215 and ISO 4892-3.
2. Type testing and quality assurance Before the market introduction of new solar modules, they undergo a variety of tests. UV exposure tests are mandatory to ensure that the module operates reliably even after decades. These tests are an essential part of certification according to IEC 61215.
3. Research & Innovation Innovative solar cells, especially those based on perovskite, are often sensitive to UV radiation. Through targeted tests with a UV light lamp, developers can test special protective mechanisms and coatings to make the cells market-ready.
UV LED Lamps: The Modern Choice for UV Testing
UV LED lamps are especially suitable for demanding tests and detailed research projects. They are characterized by:
- High energy efficiency: Significantly lower energy consumption compared to traditional lamp types.
- Long lifespan: Minimal maintenance and thus lower operating costs.
- Precise controllability: Exact setting of UV wavelength, intensity, and duration of irradiation for precise and reproducible results.
- Environmental friendliness: UV LEDs contain no mercury and are therefore considered particularly environmentally friendly.
Thanks to these advantages, UV LED lamps are increasingly preferred in laboratories and research facilities.

Safety in the use of UV light lamps
UV radiation can be harmful to health. Therefore, strict safety standards are observed when using UV light lamps:
- Use of closed and shielded test systems
- Permanent monitoring by optical sensors
- Mandatory protective equipment for operating personnel
- Compliance with the IEC 62471 standard for photobiological safety
UV light lamps for a safe future in the photovoltaic industry
The targeted simulation of UV stresses using UV light lamps ensures that solar modules withstand even the harshest conditions. With their help, manufacturers and developers achieve maximum quality and a long lifespan for their products. In short: The UV light lamp is indispensable for reliable and efficient solar systems.
