1 PID-Resistance Introduction The first company with all products meet PID-resistance Dec. 2013

2 What Is PID? Voltage(V) the cells voltage (which module closest to the negative pole is several hundreds of volts. 1

3 PID-Resistant Module vs. Normal Module Higher Power degradation Serious EL defects Lower Power degradation Little EL defects Defects area 2 2

4 Key Influencing Factors & Solutions-Cell Level AR Coating -proposed by JA Solar Thickness Modification of refractive index Equipment -proposed by JA Solar Homogeneity Test Condition: Temperature: 85 Humidity: 85% Voltage: -1000V Hours: 96h REFERENCE: S. Pingel, O. Frank, POTENTIAL INDUCED DEGRADATION OF SOLAR CELLS AND PANELS, 2010 Pease be noticed that we don t do pre-degradation before testing PID, so this result probably be influenced by LID, and the real PID values should be less than those values. 3

5 Influencing Factors & Solutions-Module Level Alternative cover glass Alternative encapsulation material featuring high volume resistivity Test Condition: Temperature: 85 Humidity: 85% Voltage: -1000V Hours: 96h BOMBill of Materiel Test by JA lab 4

6 Influencing Factors & Solutions-System Level (Recommended) Grounding of the negative pole of the PV system System Level-1(-)Grounding Applying a positive potential to the negative pole of the system at night for regeneration. Applying micro-inverter : cost may be increased + - 0% System Level-2: Degradation and recovery (applied potential) -15% -30% Panel A Panel B Panel C -45% -60% -75% PID in % Negative potential -1000V Positive potential +1000V Hours 5

7 About JA Solar PID-Resistant Product Certification and Monitor result JA PID resistant product have been certified by TUV SUD & PI Berlin JA changed all cell product to PID-resistant process from Oct.2012 and monitor at regular intervals. The following is our monitor result : 87# 96h 89# 96h 91# 96h 92# 96h

8 About JA PID-Resistant Product Mass production progress-cell All meet 60,85%RH,-1000V negative voltage, All meet 25,85%RH,-1000V negative voltage, 168 hours PID resistant 96 hours PID resistant Majority meet 85,85%RH,-1000V negative voltage, 96 hours PID resistant 2012 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec JA PID-resistant cell has no effect on JAC M5SF JAC M6SF JAC P6RF module s encapsulation power-loss electrical performance reliability and color

9 JA Solar New Product With Better PID Resistance -Will Be Lunched The latest high efficiency multi-crystalline cells technology (Black Silicon), Better PID resistance performance compared to conventional modules >18.3% average efficiency of Multi-Si cells 265 W/270W rated power is expected for 6x10 modules 8
