Block diagram overview of the Solar Panel I-V Measurement System System Description: The three major portions of the system are the operator interface consisting of a LabVIEW vi running on a laptop PC; a small data acquisition system (DAS); and an electronic circuit which programs current delivered from the solar panel under test.
The feedback is the voltage produced as the solar panel current flows through the current-sense resistor R4. The more current the panel produces the greater is the feedback voltage produced at the current sense resistor (V = I*R).
A4: The sense resistor gives us a way to measure the current produced by the solar panel. Note that the DAS can measure only voltage, not current. The current produced by the panel flows through R4. As it does so a voltage drop V occurs across R4. We measure the V directly and we know the R. Therefore the panel current can be calculated from Ohm’s
Control Circuit: The control circuit (Figure 3) is used to control the current drawn from the solar panel, and to condition the current and voltage signals produced during the measurements. The circuit draws about 8 milliamps and can be powered by a 9-volt battery or by any DC voltage typically in the 9 to 12 volt range.
Panel V-divider ratio: Normally not changed from default. The actual panel voltage is divided down by two resistors (R5, R6) in a voltage divider configuration. The ratio in this option is the ratio between the actual panel voltage and the voltage presented to the DAS. The ratio does not change unless you change the resistors.
