OBJECTIVE

• To improve the IV curve characteristic
• To testing the circuit and get the output produce from PV module

METHOD

1. Firstly, test the circuit if it can produce the amount that I want
2. Then, connect the circuit to the LabVIEW and observe the graph

Figure 2: LabVIEW

Figure 3: Graph IV Curve

RESULT

For the manual test, the graph become as exactly but when try it with the LabVIEW, there are some problems when the graph doesn't come out as the actual. The graph become opposite of the actual graph. The input from PV is separate into two that is current and voltage but the graph of both is combine (IV curve) to see the performance. But the LabVIEW only can accept 10v for voltage and 58mA for current. Since the output from PV is 21v for voltage and 0.4mA for current, it is a little high for LabVIEW to accept. So, the voltage divider and current divider being use to control the output from PV to become small enough for LabVIEW to accept. The voltage divider will divide the output from PV into 2, so the input into LabVIEW will become 10v and it exactly the amount that LabVIEW can accept. For that, 1kΩ is used. The  current is used 6 resistor of 82Ω that connected in parallel to make sure the input is 50mA since the maximum current is 58mA. When test the circuit with LabVIEW, it worked but the graph is still not the actual graph.
