It handles modules up to about 2,600 mm by 1,600 mm with a 1,200 W class measurement envelope and voltage coverage from roughly 4 V to 70 V, and serves module lines from 5 MW to 1 GW. The A+A+A+ classification is the IEC 60904 requirement set: without it, flash-test results cannot be used for module nameplate rating or for certification testing. Because the simulator's light source is the reference every measurement traces back to, this is the one station where buying a lower class is not a saving, it is a recalibration problem for every module you ship.\n\nPV Module Manufacturing · by Jerry, Ooitech\n\n## Solar Panel Tester Sun Simulator GIV-20A2616 Overview\n\nThe **Gsolar GIV-20A2616 Solar Panel Tester / Sun Simulator** is a professional-grade A+A+A+ class solar module IV testing system designed for accurate electrical performance measurement of a wide range of photovoltaic modules. With a maximum illuminated area of **2600mm x 1600mm** and an adjustable long pulse duration from **10ms to 100ms**, this sun simulator delivers highly precise IV curve testing for crystalline silicon, thin film, PERC, HIT, HJT, N-type, IBC, shingled, half-cell, and LRF/LHS ribbon-based solar modules.\n\nPowered by proprietary **GSN technology**, the GIV-20A2616 achieves single-flash measurement that effectively eliminates the capacitance effect commonly found in high-efficiency and high-capacitance PV modules, ensuring reliable and repeatable test results across all advanced cell technologies. This makes it an ideal testing solution for modern solar panel production lines producing next-generation modules.\n\nOoitech supplies the Gsolar GIV-20A2616 sun simulator as part of comprehensive solar panel production line solutions, ranging from 5MW to 1GW capacity. Whether you are setting up a new production facility or upgrading your existing quality control station, this tester provides the accuracy and throughput needed for professional module manufacturing.\n\n## Technical Specifications\n\n### Core Performance Parameters\n\n| Parameter | Specification |\n| --- | --- |\n| Model | GIV-20A2616 |\n| Classification | A+A+A+ Class |\n| Max.

This ensures that every measurement meets and exceeds the strictest international standards for solar module testing accuracy.\n\n### GSN Technology for High-Capacitance Module Testing\n\nThe proprietary GSN technology enables single-flash measurement with adjustable pulse durations from 10ms to 100ms. This effectively eliminates the capacitance effect that causes inaccurate readings in high-efficiency modules such as PERC, N-type, IBC, and HJT cells. For HJT modules specifically, a 30ms pulse duration delivers highly accurate IV property measurements, solving one of the most challenging testing requirements in modern PV manufacturing.\n\n### Extended Spectrum Coverage\n\nWith a standard spectrum range of 300-1200nm and the option to extend to 1700nm, the GIV-20A2616 accommodates the testing requirements of virtually all photovoltaic technologies, including advanced thin-film and heterojunction modules that require broader spectral coverage.\n\n### Ultra-High Repeatability\n\nRepeatability error is kept below 0.3% over 40 continuous tests and below 0.5% over 100 continuous tests, ensuring consistent and reliable quality control throughout high-volume production runs.\n\n### Comprehensive Software Platform\n\n- **Multi-level access control**: Separate login accounts for QC personnel, operators, technicians, and maintenance staff with customizable permission settings for each role\n- **Advanced module classification**: Automatically sort modules into different grades based on Pmax, efficiency, Imax, I-Id, or any combination of parameters\n- **Flexible data export**: Support for MDB, CSV, and JPG formats with the ability to save both calibrated and original measurement data\n- **Real-time monitoring**: Live light intensity monitoring throughout the testing process ensures consistent test conditions\n\n### Large Testing Area with Fast Throughput\n\nThe 2600mm x 1600mm illuminated area accommodates all standard and large-format solar modules. With cycle times as low as 5 seconds at 10ms pulse duration, the system supports high-throughput production line requirements without compromising measurement quality.\n\n### Universal Module Compatibility\n\nThe GIV-20A2616 is engineered to test the full spectrum of solar module technologies including crystalline silicon, thin film, PERC, HIT, HJT, N-type, IBC, [TOPCon](https://www.ooitech.com/what-is-topcon-solar-cell-a-complete-guide-to-tunnel-oxide-passivated-contact-technology.html), shingled, half-cell, and modules using high-transparency EVA, LRF ribbon, and LHS ribbon configurations.\n\n### Long Xenon Lamp Lifespan\n\nThe xenon lamp delivers up to 100,000 flashes at 10ms pulse duration, significantly reducing consumable costs and maintenance downtime over the lifetime of the equipment.\n\n## Product Applications\n\n### Solar Panel Production Line Quality Control\n\nThe GIV-20A2616 serves as the essential final-stage quality control station in solar panel manufacturing lines ranging from 5MW to 1GW capacity. It provides precise electrical performance verification to ensure every module leaving the production line meets specified power output and efficiency ratings. Production facilities manufacturing M6, M10, M12, and other cell formats rely on this tester for accurate power binning and module classification.\n\n### High-Efficiency Module Manufacturing\n\nWith GSN technology and long pulse capability, this sun simulator is specifically optimized for production lines manufacturing next-generation high-efficiency modules including PERC, TOPCon, HJT, IBC, ABC, and HPBC technologies. The adjustable pulse duration from 10ms to 100ms ensures accurate readings regardless of the cell technology's capacitance characteristics.\n\n### Shingled and Half-Cell Module Production\n\nThe system provides accurate testing for advanced module architectures including shingled modules and half-cell configurations. These module designs present unique testing challenges due to their interconnection methods, and the GIV-20A2616's flexible measurement capabilities ensure precise IV characterization.\n\n### Thin Film and BIPV Module Testing\n\nWith the extendable spectrum range up to 1700nm, the GIV-20A2616 accommodates thin film technologies including CIGS and CdTe modules, as well as building-integrated photovoltaic (BIPV) products that may use non-standard module formats.\n\n### Research and Development Laboratories\n\nR&D facilities developing new cell technologies and module configurations benefit from the high measurement resolution (0.003% for both voltage and current) and comprehensive parameter output, providing detailed electrical characterization data for product development and optimization.\n\n### Third-Party Testing and Certification\n\nIndependent testing laboratories and certification bodies can utilize the A+A+A+ class accuracy and extensive calibration capabilities to perform reliable module performance assessments in compliance with international testing standards.\n\n## Contact Ooitech to Purchase\n\nOoitech is your trusted partner for complete solar panel production line solutions, from individual equipment like the Gsolar GIV-20A2616 Sun Simulator to fully integrated production lines with capacities from 5MW to 1GW.
