Lab Equipment Tester Machine Pv / Solar Cell Module Test IV Curve Measurement

                Keyland Solar Module Test Apparatus Serie,Solar Module IV Tester Machine

IV curve measurement Introduction:

Photovoltaic solar module take the sunlight power and convert it toelectrical power. The output power from a solar module gets higher as the intensity of sunlight gets brighter, but there are other factors that influence the output power. Power is the product of current and voltage, so measuring the current (I) and voltage (V) will characterize the pv module behavior.The IV curve of an solar module represent its entire electrical characteristic. 

From this IV curve is it possible to know a lot of parameter such as:Maximum power, Maximum current and voltage, FF. There are the key parameters that is important to know for design new installation and for check the quality of the modules. 

In-line Solar simulator is the most productive in-line Sun simulator ,Xenon Lamp Solar Simulator in the industry.Also Solar Panel Tester is used in Lab. of university.

Main Features

1) Flash pulse adjustable range 10-100ms continuously

2) 4-line measurement,14-bit 4-channel high speed synchronous acquisition card

3) 10 parameters display,Measurement Parameter displays in Tabulation and Graphic way

4) Temperature automatically compensating

5) Voice counts off and prompts, Counting prompt of flash times

6) 24 Hours continuous work

7) 8000 data collecting points

8) long service life,working life is about 300,000 times of flash Import Xenon lamp to ensure that the correct test light spectrum,

9) HMI and PLC integration touch screen control,operating more humane

10) Each test interval is less than 5 seconds, quick measurement

11) Professional developed linear scanning electron load. while ensuring accurate measurement results, but also to ensure that the measurement linearity error is less than ± 2% in the entire measurement range

12) Panel measuring device adopts synchronous motor drive, can reduce operating noise, reduce the impact from panel measuring device to solar panels, thereby reducing breakage rate.

13) Software design is simple and practical , only the correlation coefficient should be corrected when compared with the standard.

14) Crystalline silicon cells measured using a four-wire connections to ensure accurate measurements.

Measurable (display) parameters:

IV curve, PV curve, short-circuit current Isc, open circuit voltage Voc, the peak power Pm, the maximum power point voltage Vm, the maximum power point current Im, the fill factor FF, the cell efficiency η, the test temperature T. Can also be displayed by the mouse at any point on the curve corresponding to the current, voltage and power parameters.
