Solar cells and solar panels testing program of research and design – battery, battery plate – screen printing industry, especially
HC screen Special Indian network How to test solar cells and panels evaluate each session Electric Performance, when adopted Power supply Or Electronic Load inspire solar cells and panels of various electrical properties, when required to display the electrical parameters and electrical characteristics can be recorded trends related test equipment. As the solar cell and battery plate is widely used, in addition to the relevant tests in the laboratory, but also need easy to carry, easy to operate various types of test equipment.
1, solar cells and solar panels measuring resistance and voltage test
By the battery internal resistance tester (AC micro-ohmmeter 3560,3561) high-speed, high precision and stable measurement, to meet the aging test battery measuring small voltage changes
2, the battery contacts of the test board
Panels connected by the composition of small solar panels, batteries and battery time will be needed to connect nodes resistance testing, we can provide 3541 DC micro-ohmmeter for testing.
3, solar cells of large current discharge capacity and power
By setting the total time, the power meter is set to DC rectifier means to aggregate, to get the solar cells charge-discharge capacity and power of the situation. Our AC / DC single-phase power meter 3334,3334-01 can make this measurement
Such as, car solar power car, the car’s solar cells can be converted into how much power, they affect how long a car can drive, so test charge and discharge capacity, and power is crucial.
4, assessment of solar power conditioner energy efficiency
Power conditioner converts the DC AC devices *
* PV systems? Power conditioner? Measuring energy efficiency steps
Optical system measures the energy efficiency of the power regulator
Energy efficiency = output / input Based on the chart shows, by the power analyzer 3390 (4 channels) can directly view the following electrical parameters:
Primary (DC) voltage, current, power, pulse rate (only JIS)
Secondary = Output (50/60Hz or DC)
voltage, current, power, power factor, distortion rate, pulse rate (for DC output, only JIS)
overall assessment of the primary and secondary
efficiency, loss Addition to view the electrical parameters, but also need to check the regulator output transient waveform changes of the properties to be judge. The key is to check whether there are anomalies occur instantaneously, according to view high-speed waveform sampling more intuitive record reflect the market situation, so they need faster than average 10ms sampling sampling, so needed at this time a multi-channel and high-speed sampling rate of the storage recorder records voltage, current, temperature changes in the instant situation. 8870-21 to better reflect the portability, because of the battery to provide more suitable for on-site troubleshooting ,8860-51 Summary Comparison of suitable laboratory site.
8870-21 portable storage Recorder Hand-held, easy to operate At the same time direct measurement of two analog signals (such as voltage or current)
High-speed sampling 8860-51 storage Recorder High-speed sampling Multi-channel simultaneous recording, feature-rich module
