Products

• LED Light Soaker: A Class A+A+A+ steady state LED solar simulator for testing full size and mini PV modules of any technology, including perovskite and tandem. It offers a wide and tunable spectrum, adjustable irradiance and temperature control, so laboratories can measure power, stability and long term degradation.
• SPIRE XENON Manufacturing and Laboratory solar Flasher: A large area xenon flash solar simulator used in PV module production lines and in test laboratories for power determination. It fires a single long pulse of simulated sunlight and records current voltage characteristics with high repeatability for all module types and sizes.
• SPIRE Temperature Controlled PV Laboratory solar Flasher: A xenon flash laboratory solar simulator combined with a temperature controlled chamber. It is used to determine module power, temperature coefficients to IEC 61215 and energy rating to IEC 61853, including bifacial and high efficiency module types.
• Mini LED Light Soaker: A small steady state LED solar simulator for solar cells and PV mini modules, aimed at perovskite, tandem and thin film research. Modular LED panels set the test area, and a built in IV measurement system records power, degradation and stability during scale up.
• Mini IV measurement system for testing PV mini-modules: An IV measurement and maximum power point tracking system for PV mini modules. It records current voltage curves and tracks the maximum power point by the perturb and observe method, with adjustable step size, delay time and power and noise thresholds for perovskite work.
• Micro uniformity Measurement tool: A calibration tool that measures the micro uniformity of pulsed solar simulators as recommended by IEC 60904-9 edition 3. An array of small cells maps the light field across the full test area, which matters when testing half cut cell and shingled modules.
• Uniformity Calibration Robot: A measuring robot for the non uniformity of steady state solar simulators. A long measurement module spanning the width of a PV module travels across the test plane on one axis, replacing the manual scanning of a single reference cell over two axes.
• PV module testing in the port of Rotterdam: An independent PV module testing service run with Odin Warehousing at the Maasvlakte in the port of Rotterdam. Purchased modules can be checked before they clear Dutch customs, using visual inspection, electroluminescence imaging and IV testing on an Eternal Sun solar simulator.
• PV module testing in the port of Valencia: An independent PV module testing service provided by Spire Solar Iberia, a subsidiary of Eternal Sun, inside the Amara logistics hub at the port of Valencia. Buyers can assess module quality before ownership transfer using visual, electroluminescence and IV testing.
• PV Factory inspections China, India and South-East Asia: An inspection service for PV plant owners, project owners, EPCs, installers and wholesalers buying modules in Asia. A local team can audit the factory, supervise production, arrange third party laboratory testing and run pre shipment checks for microcracks and soldering faults.
• On site service and simulator calibration: Field service, maintenance and calibration for installed Eternal Sun and Spire solar simulators. Trained engineers give on site support, calibration and troubleshooting, and new and repaired parts ship from several locations to limit equipment downtime.
