      "abstract": "Keterbatasan pasokan energi listrik yang stabil menjadi kendala utama dalam penerapan teknologi produksi modern pada agroindustri gula aren cair, khususnya di wilayah pedesaan. Penelitian ini bertujuan untuk menganalisis kinerja dan kelayakan sistem panel surya terintegrasi baterai sebagai sumber energi listrik untuk proses produksi gula aren cair. Sistem yang diuji menggunakan dua modul panel surya monokristalin berkapasitas total 1,13 kWp yang terintegrasi dengan inverter–baterai LiFePO₄ berkapasitas energi nominal 2,56 kWh (25,6 V; 100 Ah). Beban utama sistem terdiri atas pemanas listrik 500 W dan pompa vacuum evaporator 500\r\nW dengan total beban sekitar 1.000 W dan durasi operasi produksi selama 4 jam. Analisis dilakukan berdasarkan data Global Horizontal Irradiance (GHI), daya keluaran panel surya, efisiensi energi, serta perubahan State of Charge (SOC)\r\nbaterai selama pengujian pada tanggal 11, 12, 25 Oktober, dan 1 November 2025. \r\nHasil penelitian menunjukkan bahwa variasi GHI harian berpengaruh signifikan terhadap daya keluaran panel surya, dengan kondisi cuaca cerah menghasilkan performa sistem yang lebih stabil dibandingkan kondisi berawan. Integrasi baterai terbukti mampu menjaga kontinuitas suplai energi selama proses produksi, dengan SOC awal direkomendasikan berada di atas 80% untuk mencegah kondisi deep discharge. Secara keseluruhan, sistem panel surya terintegrasi baterai dinilai layak dan andal sebagai sumber energi alternatif yang berkelanjutan bagi agroindustri gula aren cair skala UMKM.",
