Natural resources may generate pollution, therefore the use of clean renewable energy<br />

resources such as solar power become major player in solution for energy crisis. This<br />

research presents the development of voltage and current logger for solar PV<br />

monitoring with designing the circuit and integrating current and voltage sensor with<br />

Raspberry Pi. The sensors are programmed in Raspberry Pi for logging the voltage<br />

and current data and the data are saved in csv file. A graph of power versus time<br />

plotted using Excel in order to analyze the data and characteristics of power versus<br />

time data for a day. As a conclusion, solar panel starts generating power just after<br />

sunrise and hitting a peak at around midday and then reducing at 6 pm.<br />
