Accurate I-V/P-V curves for full module\n\n##### Stock: Available | 30~60 days manufacturing time\n\n##### Category: Product\n\n##### Tags:\n\n---\n\n---\n\n**Quick answer:** The ST-TLD3A+ is a down-beam IV tester, and the SMTL-V21.3A+ is its up-beam low-light counterpart, together covering solar panel flash and performance testing. Both work to IEC 60904 conditions, handle modules up to about 2,600 mm by 1,600 mm with a 1,200 W class envelope, and serve lines from 5 MW to 1 GW. Down-beam testing illuminates from above the module, which suits a standard horizontal production flow; up-beam testing illuminates from below and is used to measure low-light and rear-side performance, which matters for bifacial modules. If your product line includes bifacial modules, the second configuration is not optional: a single down-beam tester cannot measure the rear contribution, and the nameplate figure will be short.\n\nPV Module Manufacturing · by Jerry, Ooitech\n\n## Product Introduction\n\nOoitech presents two professional solar panel IV testing solutions: the **ST-TLD3A+ Down-beam Tester** and the **SMTL-V21.3A+ Up-beam Long Pulse Width Component Tester**.
