The photovoltaic industry, long marked by a period of low prices, is now experiencing an unprecedented surge. Since February, industry leaders have raised prices beyond 0.7 CNY/W, with distributed module prices reaching 0.8 CNY/W, driven by increasing costs of upstream raw materials such as silicon wafers, solar cells, and EVA. This dramatic price increase has led to supply shortages, order backlogs, and market disputes. Policy-driven incentives and a revival in overseas markets have further fueled this trend. In this challenging yet dynamic environment, Yoha Solar continues to support the industry by offering high-quality, cost-efficient production equipment. Notably, the company’s IV Tester—which ensures precise measurement of solar module current-voltage performance—has just been packaged and shipped, reinforcing its commitment to quality and reliable service. | Model | YHPT-AAA | Feature | | Lamp Spectrum | In line with IEC60904-9:2007(A Grade) | 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. | | Light Intensity | 1000W/m²(700W/m²-1200W/m²) | | Light intensity non-uniformity | ≤±2%[AAA] | | Instability degree of irradiation | ≤±1%[AAA] | | Test results consistency | ≤±0.05%[AAA] | | Test error of electrical properties | ≤1% AAA | | Single flash time | 60ms 100ms 150ms(Optional) | | Effective Test Range | 2500mm×1400mm 2600*1500mm(Optional) | | Measuring Voltage | 0-200V(Resolution 1mV) | | Measuring current | 200mA-20A(Resolution 1mA) | | Environmental temperature | 15℃~30℃ | | Test Parameters | Isc, Voc,Pmax, Vm,Im,FF,EFF,Temp,Rs,Rsh | | power | 220V/50Hz(60Hz) |
