Analysis of Battery Charging Using 100 Wp Solar Cells as Power Supply for Water Desalination Equipment

Technology

Abstract

This study analyzed battery charging using a 100 Wp solar cell as a
power source in a water desalination device. The main goal is to find out the
amount of energy produced by the 100 W solar cell and the optimal battery
charging time. The research method involves the use of various components such
as solar charge controllers, 12-volt batteries, and inverters. The results showed
that the energy capacity stored in the battery reached 768 Wh, with the highest
charging efficiency on the fourth day of 137 Wh. Battery charging is affected by the
intensity of sunlight, weather conditions, and the working position of the solar cell.
Tests also show that the electrical energy generated can support the desalination
device for 10 hours with varying filling efficiency due to environmental factors. This
research provides insight into the efficiency of solar power systems in varying
weather conditions and their practical applications in water desalination.
