Solar PV Hail Tester Instrument

Instrument basic structure:
1.Pneumatic transmit system
2.Machine shift device

3.Sample holder:

4.Optical fiber Superhigh speed measure system

  

1 Pneumatic transmit system :  adjust the transmit speed of ice ball which in 
    thetransmit tube

2.Machine shift device: manual move the place of barrel ,Microcomputer change the place of the barrel through control Gearing. tracing point with   infrared ray
3.Sample holder: Design the machine shift device and sample holder conform to sample size,standard

size :2000*1350(L*H)
4.Speed test system: include detection sensor ,High-speed response module,Software modules,

 

 Principle

Make a ball mould which inner diameter in 25mm,put the ice ball in the in the barrel,then open the solenoid valve,pushing the ice ball impact the PV module with speed in 23m/s.detection the impact range,Determine  whether the PV mould qualified or not ,after appearance inspection,measurement to insulation resistance and maximum power
