Solar pump system

[Eng_Ragy]

hey guys;

I would ask for this solar pump system

W12192203ED94354E.jpg

In chart 5 KWh/m2/day
header 12 m flow rate 500 m3/day

and my location isolation is:

kWh/m²/day 2.76 3.68 5.04 6.43 7.40 8.04 7.89 7.15 6.01 4.57 3.28 2.64

For months less than 5KWh/m2/day the pumps stop or the flow rate will just decrease and the months more than 5 KWh/m3/day that mean the pump will

produce for me 500 m3/ day in 5 hours ??

Thanks;

sounds about right.
You could also double your array size for the low insolation months.

Thanks naptown as always you help me .. so increase my array for low insolation months give me 500 m3 / day with header 12m during the year

the day here mean 5 hours daylight peak ( on grid system ) right ?

another think form march till September the pump will work only 5 hours in daylight and give me the 500 m3

I would ask if i am right or wrong in this :

Pumps specification:

Header: 12 m
Flow rate : 132 m3/h
Power: 7.5 KW

I select:

Module specification:
Renesola poly-crystalline 250W

At NOCT :

Pm= 185 W
Vm= 28.2 V
Im= 6.57 Amp

Inverter specification:

SMA Sunny Tripower 8000TL
Max voltage input = 1000V
Max input current input A = 15 A
Output power = 8000 W


42 panels (14 *3)
42 *185 = 7770 W
14 in series
3 in Parallel

According to my location:
Latitude: +31.22 (31°13'12"N)
Longitude: +29.95 (29°57'00"E)

will I set my modules 31 degree N ?

Insolation, kWh/m²/day 2.76 3.68 5.04 6.43 7.40 8.04 7.89 7.15 6.01 4.57 3.28 2.64


The flow rate of pump will be
like this during the year
364 486 665 849 977 1061 1041 944 793 603 433 348 m3/h
