In recent months, the photovoltaic market has undergone a significant transformation. Once burdened by low prices below cost, industry giants have now increased their prices to over 0.7 CNY/W, with distributed module prices even hitting 0.8 CNY/W. This surge is accompanied by simultaneous rises in the costs of essential raw materials, leading to frantic ordering, order cancellations, and even product disputes. Policy incentives and a recovering international market have further driven this price rally. In response to these changes, Yoha Solar has continued its long-standing strategy of delivering high-quality, cost-effective PV production lines. The company’s IV Tester—engineered for precise I-V curve measurement—has recently completed packaging and shipment, reinforcing quality assurance in solar module production.
| Model | YHPT-AAA | Feature |

1. Measurable parameters: I-V curve, short circuit current, open circuit voltage, peak power, peak power point voltage, current, fixed voltage current, filling factor, conversion efficiency, light intensity and environmental temperature. 2. Automatic classification and display function. It can be automatically classified according to the fixed voltage and current, and the results of the classification can be displayed directly on the test cabinet by digital display. Easy to use in production line. 3. Solar cells are connected by four wires to ensure the current accuracy. 4. Measuring temperature and light intensity at the same time to ensure the accuracy of automatic correction of solar cell temperature and light intensity. 5. Self-tuning system with manual input compensation parameters, automatic/manual temperature compensation, automatic light intensity compensation, etc. |
