Title of Activity:

Project Progress.

ü  Testing the Solar Panel

Objective:

For make sure this Solar Panel are functioned.

Measure the output value from the Solar Panel (directly without any circuit).

Determine the maximum performance using this Solar Panel.

Content/Procedure:

For make sure this Solar Panel are functioned, using the sun light (radiation of the sun) to testing this Solar Panel.

Measure the voltage and current output produced from the Solar Panel using Multimeter.

To produce the max output, try to test with the different time on this Solar Panel.

Result and Analysis:

As a result, for make sure the Solar Panel is functioned;

ü  The Solar Panel exposed to the sun light and it produced the power.

ü  And the Solar Panel will produce the different output power depending on the brightness of the sunlight.

ü  To reach the high value of the output power, it should expose to the blazing sun brightness.

And for measuring the output value produced from the Solar Panel, the Solar Panel should measure directly using the Multimeter. As a result, the output value reading that produced from that Solar Panel has gained some output value. So, the multimeter have been set to 20V to measure the voltage gained from the Solar Panel. And the voltage that produced are around 15.09V~19V (depending on the brightness of the sunlight). And the multimeter have been set to 200mA to measure the current gained from the Solar Panel. And the current that produced are around 0.01mA~0.1mA.

Picture of Measured Output Voltage Value 15.09V (Cloudy)

Picture of Measured Output Current Value 10.12mA (Cloudy)

Picture of Measured Output Voltage Value 20.5V (Sunny) 

Picture of Measured Output Current Value 440mA (Sunny)  

Conclusions:

            As a conclusion, the Solar Panel can be operating when we expose to the blazing sun brightness and there will give the electricity output. And this Solar Panel can produce a output value,  and as an improvement to gain more output value, this part will combine with the other part for make sure all combined parts will give a high output value.

Lastly, based on the experiments the output value can be produce more, depending on different brightness of the sunlight. The brightness of the sunlight are effected the output result.
