After years of low pricing that left many companies struggling, the photovoltaic industry has witnessed a dramatic reversal since February. Leading firms have raised prices, pushing PV component costs beyond 0.7 CNY/W—with distributed modules even reaching 0.8 CNY/W. At the same time, upstream raw materials such as silicon wafers, solar cells, and EVA have risen in price, triggering a rush for supplies and order backlogs into the second quarter. Amid this market turnaround, Yoha Solar remains committed to its strategy by providing high-quality, cost-effective PV production equipment. Recently, the highly praised IV Tester—designed for precise current-voltage measurements of solar modules—was successfully packaged and shipped, reaffirming its role in quality assurance and market stability.

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. |
