Eternal Sun???s product portfolio is centered on a range of precision instruments designed for both continuous-light research applications and high-throughput manufacturing quality assurance.
LED Solar Simulators (Light Soakers and Flashers): The flagship offerings include the LED Light Soaker, LED Mini Light Soaker, and LED Flasher systems. These instruments are vital for conducting light-induced degradation (LID) and light-and-elevated-temperature-induced degradation (LETID) testing, which are crucial for assessing the long-term stability of solar cells and modules. The instruments are often certified as A+A+A+, adhering to stringent international standards like the IEC 60904-9 Ed. 3. They offer a wide spectral range, typically between 300-1200 nm, and enable functionalities like spectral tuning, IV measurement, and recipe creation in a temperature-controlled environment.
Continuous Light Technology (Solid State): Eternal Sun holds patented solid-state (continuous light) technology. This is primarily utilized by R&D institutions to emulate sunlight with high accuracy, up to 98%. Continuous light simulation is necessary for specific material science research and advanced degradation studies on PV materials.
Flash Technology: Through strategic acquisitions, the company has integrated flash technology into its offerings. Flashers are critical for manufacturers, providing rapid quality assurance during the solar panel production process. This allows for efficient inline testing and quality control in high-volume manufacturing environments.
Specialized Boards for Space PV Testing: A recent innovation includes the provision of new Light Emitting Diode (LED) boards, which can be pre-calibrated for Air Mass Zero (AM0) testing. This option enables the company's existing and new flagship simulators to perform tests on space solar PV, including next-generation technologies like perovskites and tandem cells. These boards can be used for testing cells, mini-PV modules, and full-scale space modules.
Services: PV Testing and Quality Assurance
Beyond the sale of equipment, Eternal Sun provides extensive services to ensure the quality and bankability of solar assets across the entire value chain.
PV Module Testing Services: The company operates its own PV testing services in strategic locations, such as the harbors of Rotterdam and Valencia. These services provide independent, third-party validation and certification of PV modules.
Inline Testing and Quality Control: Eternal Sun offers inline testing services within major PV manufacturing countries, including China, India, and Vietnam, assisting producers with setting up and maintaining quality control within their production lines.
Calibration and Performance Validation: The technology incorporates a calibration module to ensure that the measurements taken by clients are accurate and regularly confirmed. This is a fundamental service to guarantee the reliability of the solar testing data.
Solar Inspection Services: The company also performs solar inspection services for clients, including solar farm owners, providing a comprehensive assessment of solar assets in the field.
In essence, Eternal Sun provides the tools and expertise to turn "the new into the known," transforming research and theoretical possibilities into trusted, bankable industry standards, thereby supporting the solar sector's drive towards becoming the world's leading energy source.
