Pemanfaatan Pembangkit Listrik Tenaga Surya (PLTS) di Indonesia dipengaruhi oleh faktor-faktor seperti kondisi geografis, kebijakan pemerintah, dan kondisi ekonomi masyarakat. Meskipun Indonesia memiliki potensi sinar matahari yang besar sepanjang tahun, penggunaan energi surya masih belum optimal. Pemerintah telah menerapkan kebijakan dan program-program seperti program 10.000 MW. Perencanaan PLTS on grid di Café menghasilkan 1856 kWh/tahun.Pada pensimulasian PLTS yang terpasang menggunankan PVSyst menghasilkan energi listrik 1.6 kWp.Nilai COE yang di dapat sebesar Rp. 620,00 / kWh. Biaya tagihan listrik setelah pemasangan PLTS sebesar Rp. 191.784 ,00 biaya investasi awal PLTS Rp. 26.800.000,00Performance ratio sebesar 82% apabila performace ratio lebih dari 60 % dan kuran dari 90%maka perencanaan pemsanagan PLTS dikatakan layak. Penelitian ini bertujuan untuk mengevaluasi efektivitas dan keuntungan ekonomis dari implementasi PLTS dalam konteks spesifik kafe tersebut.

The use of Solar Power Plants (PLTS) in Indonesia is influenced by factors such as geographical conditions, government policies, and people's economic conditions. Although Indonesia has great potential for sunlight throughout the year, the use of solar energy is still not optimal. The government has implemented policies and programs such as the 10,000 MW program. Planning for on-grid solar power plants in Café produces 1856 kWh/year. In the simulation of the installed solar PV, PVSyst produces 1.6 kWp of electrical energy. The cost of electricity bills after the installation of solar power plants is Rp. 191,784.00 initial investment cost of solar power plants Rp. 26,800,000.00Performance ratio of 82% If the performance ratio is more than 60% and the ratio is less than 90%, then the planning for the installation of solar power plants is said to be feasible. This study aims to evaluate the effectiveness and economic benefits of the implementation of solar power plants in the specific context of the café.
