Optimal Power Analysis for the Installation of On-Grid Rooftop Photovoltaic Solar Systems (RPVSS) in the Industrial Engineering Laboraturiom Building, Bukit Indah Universitas Malikussaleh Lhokseumawe Aceh

Nationally, Indonesia has targeted renewing up to 23% of its mix of renewable energy sources by 2025. To support the program, the government has also planned the construction of Rooftop Photovoltaic Solar Systems (RPVSS), in this case, a roof-top plant. Industrial Engineering Laboratory Building, Universitas Malikussaleh. Potential energy calculation to be generated from the installation of on-grid roof-top solar power plants using the Global Solar Atlas application based upon the area of the roof and also the optimization of energy absorption based on data on electricity usage from the laboratory building for the last three months using the data usage of energy transaction measurement tools, namely kWh meter. The analysis results disclosed that 115 solar panels (300 WP Shinyoku Polycrystalline) need to install to obtain the maximum RPVSS power. The 34,429 Wp power has produced 21% of the building roof area to supply maximum load at noon at 17,559 Wh.
