Current Sorting: Suntech sorts modules into 3 amperage categories (I1, I2 ,I3) for

Maximum string output

Product benefits- Performance /current sorting

PModule = UModule x IModule

VString = sum(VModule 1 .. VModule N)

IString = min (IModule 1 .. IModule N)

27

Product Benefits - Performance

SUNTECH´s current sorting

in a serial connection the weakest current determines the total

strength of current in the string

Example of STP250S-20/Wd, taken from a customer flash list:

Calculation without current sorting

String 1 Ø 254,06 Wp x 25

Impp Max. 8,49 A Δ = - 0,27 A = Ø 245,98 Wp x 25

Impp Min. 8,22 A Δ = - 3,2 %

String 2 Ø 253,7 Wp x 25

Impp Max. 8,47 A Δ = - 0,26 A = Ø 245,90 Wp x 25

Impp Min. 8,21 A Δ = - 3,1 %

String 3 Ø 254,18 Wp x 25

Impp Max. 8,53 A Δ = - 0,33 A = Ø 244,34 Wp x 25

Impp Min. 8,20 A Δ = - 3,9 %

String 4 Ø 253,49 Wp x 25

Impp Max. 8,47 A Δ = - 0,32 A = Ø 243,91 Wp x 25

Impp Min. 8,15 A Δ = - 3,8 %

= 24,5 kWp

28

Product Benefits - Performance

SUNTECH´s current sorting

without current sorting the installer gives away power

due to FIT cuts it gets more and more difficult to get a good ROI

29

Calculation with current sorting

String 1 Ø 253,37 Wp x 25

Impp Max. 8,26 A Δ = - 0,11 A = Ø 250,00 Wp x 25

Impp Min. 8,15 A Δ = - 1,3 %

String 2 Ø 253,72 Wp x 25

Impp Max. 8,35 A Δ = - 0,08 A = Ø 251,29 Wp x 25

Impp Min. 8,27 A Δ = - 1,0 %

String 3 Ø 254,08 Wp x 25

Impp Max. 8,41 A Δ = - 0,06 A = Ø 252,26 Wp x 25

Impp Min. 8,35 A Δ = - 0,7 %

String 4 Ø 254,62 Wp x 25

Impp Max. 8,53 A Δ = - 0,12 A = Ø 251,04 Wp x 25

Impp Min. 8,41 A Δ = - 1,4 %

Product Benefits - Performance

SUNTECH’s current sorting:

all SUNTECH standard products are presorted by Power first, then by current

delivery comes in 3 different classes: I1, I2 und I3

a Current sticker can be found in the frame, and out of every pallet

presorting is not charged by Suntech

better system performance guarantees customer satisfaction

2/3 of yearly average irradiation is

as per definition weak light

1. Chemical edge cutting process

2. High fill factor

Excellent weak light

performance

Excellent Weak Light Performance

Explanation Weak Light Conditions:

Measured irradiation is typically between

200 W/m² and 800 W/m²

Irradiation intensity for weak light conditions

is below 400 W/m²

e.g. cloudy, dusty etc. weather conditions

morning and evening hours

SUNTECH‘s edge insulation process

patented process

treatment in an acid bath

removal of unfavorable phosphor

particles along the edges

without process: leak current power

loss

increase of the shunt resistance

1. Chemical edge cutting process

2. High fill factor

Product Benefits - Performance

Excellent Weak Light Performance

Fill Factor:

FF = (Impp x Umpp)/(Isc x Uoc)

ideal FF would be 1 but is technically

not achievable

fill factor shall be between 0 and 1

the higher the fill factor the better
