Energi listrik sangat penting untuk kebutuhan sehari-hari. Pemakaian peralatan elektronik pada saat ini terus meningkat, maka sangat berpengaruh terhadap konsumsi daya listrik yang besar. Dibutuhkan energi alternatif yang lebih ramah lingkungan, bersih, dan tidak terbatas, salah satunya yaitu energi surya. Pada penelitian ini akan menerapkan pembangkit listrik tenaga surya sebagai atap langsung pada warung UMKM, kemudian dilakukan tahapan perhitungan komponen PLTS, terlebih dahulu
mengetahui beban yang digunakan pada warung UMKM. Selanjutnya melakukan analisis efisiensi dari masing-masing komponen PLTS termasuk efisiensi beban, dan analisis ekonominya. Parameter yang digunakan dalam pengambilan data yaitu input dan output tegangan, arus dari produksi PLTS, konsumsi beban, kemudian menghitung biaya Life Cycle Cost (LCC), biaya tarif listrik sistem Levelized Cost of Energy (LCOE), Pay Back Period (PBP), dan kriteria kelayakan investasi Net Present Value (NPV). Hasil
dari perhitungan didapatkan total beban pada warung UMKM sebesar 1710 Wh, maka dibutuhkan panel surya sebanyak 6 buah dengan kapasitas 100 Wp jenis Polycrystalline, SCC tipe PWM dengan kapasitas 60 A, baterai dengan jenis VLRA 12V 200 Ah, dan Inverter jenis pure sine wave 1000 W. Pengujian selama 7 hari didaptakan efisiensi dari panel surya sebesar 7,92 %, SCC sebesar 69,99 %, baterai 72,35 %, inverter 95,92 %, dan produksi total energi listrik yang dihasilkan PLTS selama 7 hari didapatkan rata-rata
sebesar 1,362 kWh dengan konsumsi beban harian rata-rata sebesar 1,392 kWh. Analisis ekonomi didapatkan biaya investasi (LCC) untuk lifetime sistem selama 20 tahun sebesar Rp.27.645.000, tarif
LCOE harga listrik sebesar Rp. 2.781,14/kWh, dengan (PBP) selama 20 tahun, dan nilai dari NPV positif maka investasi yang dilakukan dapat dikatakan layak.
