Class AAA Steady state sun simulator ( included the IV curve tester) / test chamber / Solar panel testing machine 

Purpose

This machine will offer a near natural light source under the certain area, the light source class is BBA, It’s mainly used for large area of pv module aging testing.

Testing standard 

According to IEC 61215-2016,IEC 61730-2016

Testing machine structure

1 The chamber of testing machine

2 The chamber of testing machine:foam board, It's made of completely cut off sunlight and keep 

   warm foam board materials assembly together

3.Testing sample placed frame:40mm×40mm aluminum profile,Open structure is conducive to cold

  air circulation, rapid and constant temperature on the back of pv module

4.The inner chamber structure: two layer, light source layer and testing layer, the height of testing

  layer approx 1900mm

5. Testing layer temperature control: fan cooling system, automatic constant temperature system

The Light Source specifications 

single group light source size

Power

1.Power type: EPS power

2. Power feature:Electronic Square Wave Current Power Supply,No stroboscopic

3.Software control:Independent industrial touch screen control electric cabinet and micro-computer touch control interface control

4.Adjustable function: Radiation intensity regulation, parameter display, lamp state, temperature over display

5. Adjustable range: the power within 60-100% , for the lamp group and single lamp can automatic adjustable via software

Light source hang system

1 .Light source hang system:upper hang ways: the main frame use high strength , and easy to move’s aluminum profile structure, between every lamp’s space can adjustable, debugging finished after, light source distance pv module’s distance approx 1.5m

2. Light ways: upper light, It’s easy placed pv module

Irradiation Sensor

The sensor use thermoelectric effect principle, sense components adopts winding plated multi-contact thermopile, Its surface is coated with a black coating with high absorptivity.hot junction on the sensing surface ,The cold nodes are located in the inner chamber, cold and hot junction produce the temperature difference potential, within linear range, The output signal is proportional to the solar irradiance. In order to reduce temperature’s effect , will matched the temperature compensation circuit, In order to prevent the influence of environment on its performance, will use 2 layer quartz glass cover, the quartz glass cover is via precision optical cold process grinding produce

Temperature control system

1. Fan cooling system,Temperature control 50±10℃

2. PID automatic temperature compensation control

3. Controller: Mitsubishi

Electricity requirements

1.Running environment: standard lab environment, temperature 25±2℃, humidity:60%

 2.Electricity:380V 50Hz   

 3. Power: 90KW , current:100A
