Standalone hybrid generation system for the remote area of Thar, Pakistan
4.2. PV Array Technical Specification
The 100-kW PV array of the detailed model uses 330 SunPower modules (SPR-305).
The array
consists of 66 strings of 5 series-connected modules connected in parallel (66*5*305.2 W= 100.7
kW).
Manufacturer specifications for one module are:
•
Number of series-connected cells: 96.
•
Open-circuit voltage: Voc= 64.2 V.
•
Short-circuit current: Isc = 5.96 A.
•
Voltage and current at maximum power: Vmp =54.7 V, Imp= 5.58 A.
As the 100 KW PV Array consist of 66 strings of 5 series-connected modules connected in parallel,
hence I have to design the single PV panel first by using solar cell then I can add them in series to get
the required output voltage.
4.2.1. PV Panel Model
Fig.-4.2 PV panel Model
Each PV panel consists of 96 solar cells with 16 sub-systems with 6 solar cells. Below is the snap of
the single sub-system showing how they are connected in series.

From the above graphs we can see that from each panel we are getting3 00
watt while in the data
sheet the graph shows maximum power of 305 W but due to losses in the system 300
watt is
acceptable. In the thesis as it has been already been explain in the chapter-2 that the maximum power
output from PV array system is 100KW hence we need to add 5 panel in
series to get the desired
output voltage.
