The procurement was part of the company's effort to build up in-house quality control and reliability testing for its solar module production. ### 3A Grade IV Tester The 3A grade [solar simulator](https://www.ooitech.com/solar-panel-tester-sun-simulator-otmt-a-aaa-class-solar-module-iv-tester-ooitech.html) and IV tester is designed to measure the electrical performance of solar panels under standard test conditions (STC). The "3A" classification means the equipment meets the highest standards in spectral match, spatial uniformity, and temporal stability according to IEC 60904-9. This allows the Algerian manufacturer to accurately characterize power output, current-voltage curves, and efficiency of each module before shipment. ### Environmental Test Chamber The environmental test chamber supports temperature cycling, humidity exposure, and freeze testing in accordance with IEC 61215 standards. These tests simulate years of real-world weathering in a compressed timeframe, helping identify potential defects such as delamination, cell cracking, or [junction box](https://www.ooitech.com/junction-box-welding-machine-ks-01c-automatic-solar-panel-junction-box-soldering-equipment-ooitech.html) failures before products reach the field. This equipment delivery reflects the growing demand for solar panel testing infrastructure across North Africa as the region continues to expand its renewable energy capacity. --- ##### Tags : ![](/template/ooitech/assets/img/shape/06.png) ![](https://cdn.ooitech.com/runtime/image/w800_h700_fitblur_v2_w800_h700_fitblur_v2_1757399770541443.webp) ### Request A Quote All uploads are secure and confidential. ## We deliver expertise you can trust our service Direct-from-Factory Equipment. ![](/template/ooitech/assets/img/icon/money-2.svg) ### Cost-Effective Advantages We deliver exceptional value, maximizing results while optimizing budgets for clients. ![](/template/ooitech/assets/img/icon/staff.svg) ### Our Experience Team Our skilled professionals specialize in innovative solutions and tailored strategies. ![](/template/ooitech/assets/img/icon/certified.svg) ### 15+ Years Industry Experience Deep expertise ensures reliable, trend-aware, and proven outcomes for success. ![](https://cdn.ooitech.com/static/upload/image/20250910/1757477357667605.webp ) ![](https://cdn.ooitech.com/static/upload/image/20250910/1757477724911512.webp) ![](/template/ooitech/assets/img/shape/06.png) ## What Our Client Say's about us Client testimonials praise our deep understanding of their challenges, which leads to innovative solutions and strong ROI.
