Optimizing the Design of the Solar Cell Roof at Universitas Sumatra Utara by PVsyst

The use of solar cells continues to increase in the community because the source of this power plant is solar energy, which is not only environmentally friendly, it is also easy to install and has low maintenance costs with abundant and unlimited energy sources. Meanwhile, limited land for solar cell installation is a problem in big cities, including at the Universitas Sumatra Utara (USU). So this study optimizes the solar cell design on the Universitas Sumatra Utara roof using PVsyst software. Furthermore, this study estimates the amount of energy that will be generated by utilizing the roof of the USU building (22 Buildings). The results obtained are the optimal design using the Si-Mono 335 Wp PV module, 30 Volt with an orientation of 5°, and the energy generated from the entire building is S,270.5 MWh/year.
