Abstract

The need for large amounts of electrical energy and the negative impact of carbon emissions have encouraged all countries to develop renewable energy sources and reduce fossil energy sources which produce a lot of carbon emissions. One promising source of renewable energy is solar energy, which can be converted into electricity through Solar Power Plants. The Indonesian government has committed to increasing the renewable energy mix by 57% by 2035 and reducing carbon emissions by 29 % by 2030. To support the Indonesian government's commitment, the Widya Mandala Foundation has built Solar Power Plants on all campuses of Widya Mandala Surabaya Catholic University. This article intends to communicate the design and implementation of a 232.2 KWp rooftop and on grid Solar Power Plant located on one of these campuses. The Solar Power Plant has been designed and implemented using 430 units of 540 Wp solar panels, 2 units of 110 KWac inverters. It would produce 363.5 MWh of electricity per year. Based on the implementation results, the following output was obtained: from May to December 2022, was generated 221.788 MWh of electricity and 88.7 ton of CO2 avoided. Then from January 2023 to May 2023, was produced 145,400 MWh of electricity and 58.2 ton of CO2 was avoided. The implementation of 232,2 KWp Solar Power Plant is a significant step toward environmentally friendly energy. It also contributes to carbon footprint reduction and support sustainable development goal.
