c. Mechanical

1 bubble level

Pliers

Screwdrivers

Cutters

III. Results and Discussions

Figure 1 Solar Isolation on the Horizontal Surface

During the progress of the experiment, sky remain covered with thick clouds that produce rain

making the sun’s isolation to become less as measured by the pyranometer. But because the

experiment begun 10:40am, the sun is still rising that the recorded solar irradiation is increasing. Thick

clouds moving in the sky makes most of the fluctuations of the measured solar irradiation.

Pyranometer output is in millivolts, to make its units for solar irradiation, a conversion constant

of the pyranometer is used which is 14.29 μV/ (W/m2).

Figure 3 I-V Curves of Different Sunlight Intensities

The first I-V graph (figure 2) shows all the curves generated from plotting the data obtain from

experiment runs A to F. But because some of the curve exhibits great fluctuations due to fluctuations of

solar irradiation only curve B, E and F are taken into the analysis as shown in figure 3. As observe, as the

irradiation increases, so also the current produce in the solar panel. I-V curve B is less compared to the

other two curves because the solar irradiation is only 160.48 W/m2 compared to curve E and F which is

284.60 and 270.16 W/m2 respectively (Table 3.a).

Also, for a certain irradiation, as the voltage increases, the current remains almost unaffected,

but as it approach the open circuit voltage (18 volts), it suddenly drop to zero, that means it already

passed its maximum power point where nominal current and voltage is attained, and there is no current

flowing at all at open circuit voltage. Therefore it can be concluded that the current produce is directly

proportional to the irradiation. From the correlation below, it is computed that the short circuit current,

ISC = 0.0036 G
