Analysis Of Solar Power Plants With A Capacity Of 100 Wp With Automatic Transfer Switch In The Energy Conversion Laboratory Of Semarang State Polytechnic

Abstract

Solar energy is one of the renewable energy sources
by utilizing the sun as its energy source. The planning of the
PLTS uses an on-grid system, the system is still connected to
the PLN network. The system is used as a backup for
electricity flow. The system will work automatically when the
PLN electricity flow is cut off by utilizing the Automatic
Transfer Switch (ATS) control system. The PLTS was tested by
measuring the voltage, current, and input and output power
for 5 days from 09.00-15.00 WIB with data collection every 60
minutes. Then calculations were made to determine the
efficiency of the PLTS. Calculations were also made of the
energy produced by the panels needed and produced by the
lights ideally and actually. The results of the DC voltage and
DC current tests on average at a load of 70 Watts produced by
the solar panel were 12.7 V and 2.41 A with a data collection
period of 7 hours, producing energy of 214.3 Wh and
producing the highest efficiency of 7.9% and the lowest 4.84%.
