Unjuk Kerja Pembangkit Listrik Tenaga Surya (Plts) 26,4 KWP Pada Sistem Smart Microgrid Unud

Development to new renewable energy still lower than Indonesia's target of 23% in 2025. For this reason, alternative solutions are needed, namely the use of renewable energy, one of which is from the solar energy sector, namely solar PV. Solar energy has the highest potential compared to other renewable energy sectors of 207.9 GW. Based on that, in 2020 the Province of Bali received a Rooftop Solar PV grant through the Ministry of Energy and Mineral Resources, one of which is located at the Bali Provincial DPRD Government Office with an installed power of 25 kWp using the On Grid system. Based on this, it is necessary to conduct a detailed study of the potential, operational systems, savings and the proper management model of Rooftop Solar PV at the Bali Provincial DPRD Office. The potential of Solar PV electricity production on the roof of the Bali Provincial DPRD Office was analyzed by simulating the orientation and tilt angle of the Solar PV to get the optimum Solar PV electrical energy production results using HelioScope software. The results showed that the results of electrical energy production in the simulations of the two scenarios tended to be higher with the total difference in scenario 1 and scenario 2 being 21.75% and 19.66%, respectively. For savings that can be obtained for 6 months of Rp. 36,055,301 with a percentage of 22.60%. The PLTS management model in the future is located in the general section, precisely in the Sub Coordinator of the Equipment, Assets and Household Substance Unit.

Rooftop solar power plant is energy that utilizes solar energy as anenergy source which is then converted into electrical energy as well as analternative to environmentally friendly electricity generation. Rooftop solar power plants can beinstalled on the roofs of large buildings,the roof of the STIE Widya Gama campus with an areaof 2698.4 m2. Rooftop solar power plant aims as an additional power supply to supply electricalpower to the Sekolah Tinggi Ilmu Ekonomi Widya Gama Lumajang campus of 53 kVA installedpower on transformer 1. The design of a rooftop solar power plant at the STIE Widya GamaLumajang Campus uses 100 solar modules of type Vertex TSM-DE18M(II) 500 Wp. Inverterwith a capacity of 53 kVA as much as 1 unit type SUNNY TRIPOWER CORE1.solar power plants produce electrical energy of 82322,2 kWh/year to supply theload on STIE Widya Gama Lumajang. Initial investment capital of Rp. 567.005.500maintenance and operation costs of 1% of the investment capital cost of Rp.5.670.055 and payback periode for 14 years 6 months if inflation in Indonesia is4.25%.

“…Menurut Badan Pusat Statistik Badung, kabupaten Badung memiliki luas wilayah yang cukup luas yakni 418,50 km 2 atau sekitar 7,43 % dari total keseluruhan wilayah Bali [7]. Melihat potensi tersebut, pembangunan PLTS yang dapat dilakukan pada daerah tersebut ialah PLTS atap pada gedung Hotel, mal, gedung pemerintahan, gedung akademik seperti PLTS Smart Microgrid Unud [8], PLTS Kantor Gubernur Bali [9] dan PLTS Pusat Pemerintahan Badung [10].…”

Solar Rooftop PV is one solution in reducing CO2 emissions and the increasing consumption of electrical energy. Based on PP No.79 of 2014, Indonesia is committed to utilizing 23% of the total renewable energy of the total by 2025. In the General National Energy Plan (RUEN), in 2025 Indonesia targets the capacity of electrical energy from new and renewable energy of 45 GW of which solar power of 6.5 GW (14%). In this research, we will discuss the design of Solar Rooftop PV in the Udayana University Library building. Based on the helioscope simulation results, at a real angle of 20.6o and 20.3o solar modules that can be installed as many as 84 units with a power capacity of 28.1 kWp while at an optimum angle of 14.66o, as many as 66 solar modules can be installed with power capacity of 22.1 kWp. Based on the results of the HOMER simulation, the configuration between the real angle PV mini-grid and the grid is able to produce energy of 83,253 kWh/year with an emission reduction of 41.764%, while the configuration of the Solar Rooftop PV with the optimum installation angle with the grid is able to produce energy of 79.775 kWh/year with a reduction in emissions of 34.527%. From the results of the HOMER simulation, an economic analysis was carried out with an energy selling price of Rp. 900/kWh. The two Solar Rooftop PV designs are worth investing in where the Solar Rooftop PV design with a real installation angle of 20.6o and 20.3o is able to return the initial investment costs in the 17th year while the Solar Rooftop PV design with an optimum installation angle of 14.66o able to return the investment cost in the 20th year.
