dc.description.abstract | In order to achieve a transition towards a more sustainable society,
renewable energy plays a pivotal role in creating a clean energy system, reducing
greenhouse gas emissions, and improving the quality of life for the present and
future generations. The research is located on Jalan Dusun Sedar, Galang District,
Deli Serdang Regency, North Sumatra. Field observation and data analysis
methods will be employed in the study. The objective of this research is to obtain
values for power, electrical energy, and efficiency from photovoltaics used in an
IoT-based automatic fish feeder device. The electrical power requirement to
operate the IoT-based automatic fish feeder device is 48.75 watts. Sunlight intensity
begins to rise from 10:00 am to 1:00 pm with an average of 787.75 - 913.44 W/m2
at an average temperature of 33.8 – 36.9 ˚C. Photovoltaics can generate electrical
power of 22.75 watts per hour, resulting in a daily electrical energy output of
159.25 Wh and a daily average efficiency of 6.91%. The research findings indicate
that temperature and wind speed do not directly influence the absorption of sunlight
by photovoltaics. | en_US |
