Monitoring of Photovoltaic Performance as an Alternative Energy Source in Campus Buildings

Abstract

Universitas Bangka Belitung is currently supplied by electricity from the State Electric Company in 690 kVA. Concerning utilizing renewable energy at Universitas Bangka Belitung, the solar power plant is an alternative energy source that will implement. Therefore it is necessary to design a solar power plant with a monitoring system to be known at any time the performance of the solar power plant. Monitoring is conducted in real-time via a website displaying several photovoltaic parameters, including voltage, current, humidity, temperature, and solar irradiation. From the measurement results obtained environmental parameters for temperature between 26°- 56.4°C, humidity 23.6% RH - 85.6% RH and solar irradiation 4.4 W/m2 - 1281.4 W/m2. The measured voltage of 11.41 - 18.95 volts with the rated current from the load used is 0.05 - 1.5 amperes.
