Abstract

The Community Service (CS) project was implemented in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, East Java. The target beneficiary was UD. Arta Lumintu, a local SME engaged in beef cattle farming. The farm, established in 2017, was temporarily closed due to the Covid pandemic and resumed operation after a year. Key challenges included high temperatures (24-31°C) and humidity (74-77%), which negatively impacted cattle productivity and excessive electricity consumption for cattle shed operations. The project aimed to address these issues by installing a water spray system with a high-pressure pump and an off-grid solar power system. The system effectively reduces temperature and humidity in the sheds while minimizing electricity costs. The installation consists of a 540 Wp solar panel, a 1500 VA Smart inverter, a 100 Ah VRLA battery, and six pressurized water sprinkler points positioned in various areas of the cattle sheds, powered by a 350 W booster pump. This initiative improves farm efficiency, supports energy independence, and introduces smart farming technology to benefit local farmers.

Abstract

This study investigated the implementation of a Battery Management System (BMS) as a protective and performance-enhancing component in a small-scale hybrid solar power plant storage system rated at 10 × 100 Wp. Battery degradation, voltage imbalance, and excessive discharge currents are persistent challenges in off-grid and hybrid photovoltaic systems, particularly in rural electrification applications. The purpose of this research was to evaluate the effectiveness of an active cell balancing–based BMS in improving battery voltage stability, regulating discharge current, and extending battery life cycles.The research employed an experimental method by comparing system performance before and after BMS installation under identical charging and discharging conditions. Experimental results showed that prior to BMS installation, charging voltages among four VRLA batteries were unbalanced, ranging from 13.70 V to 13.80 V, and discharge currents reached up to 50.3 A. After BMS implementation, charging voltages became uniform at approximately 13.44 V, while discharge currents were limited to a maximum of 29.9 A. Furthermore, the SOC threshold was regulated from 100% to 90%, and discharge duration increased from 1.5 hours to 2 hours. Based on battery datasheet analysis, the estimated battery life cycle increased from a maximum of 372 cycles to 572 cycles. These findings indicate that the integration of a BMS with active cell balancing significantly enhances operational stability, thermal safety, and battery longevity. The results imply that BMS adoption is essential for improving reliability and sustainability of small-scale hybrid solar energy systems.

Abstract

Peningkatan kebutuhan energi listrik di salah satu lembaga sosial pendidikan di Singosari mendorong pengembangan pembangkit listrik tenaga surya (PLTS) sebagai sumber energi alternatif. Penelitian ini mengevaluasi kinerja PLTS hibrida skala kecil berkapasitas 1 kWp pada kondisi berbeban aktual. Sistem terdiri dari 10 modul monocrystalline 100 Wp dengan konfigurasi 2S5P. Evaluasi difokuskan pada sisi array PV sampai titik input inverter melalui pengukuran iradiasi, suhu modul, tegangan operasi, dan arus operasi selama pukul 10.00–16.00. Parameter yang dianalisis meliputi daya keluaran, efisiensi array, energi, specific yield, performance ratio, dan estimasi rugi performa. Hasil pengujian menunjukkan iradiasi rata-rata 796,02 W/m², suhu modul 39,51 °C, tegangan operasi 31,62 V, arus operasi 20,03 A, dan daya keluaran 651,18 W. Efisiensi rata-rata titik pengukuran sebesar 15,47%, sedangkan efisiensi berdasarkan parameter rata-rata sebesar 15,67%. Energi selama enam jam pengujian sebesar 3,91 kWh, dengan specific yield 3,91 kWh/kWp, performance ratio 81,8%, dan estimasi rugi performa 18,2%. Hasil ini menunjukkan bahwa PLTS hibrida 1 kWp dapat berkontribusi sebagai pengembangan kapasitas energi, tetapi belum dapat diklaim memenuhi seluruh kebutuhan energi harian. ABSTRACT The increasing electrical energy demand at a social-educational institution in Singosari encourages the development of a solar photovoltaic system as an alternative energy source. This study evaluates the performance of a small-scale 1 kWp hybrid photovoltaic system under actual loaded conditions. The system consists of ten 100 Wp monocrystalline modules arranged in a 2S5P configuration. The evaluation was limited to the PV array side up to the inverter input by measuring irradiance, module temperature, operating voltage, and operating current from 10:00 to 16:00. The analyzed parameters include output power, array efficiency, energy, specific yield, performance ratio, and estimated performance loss. The results show average irradiance of 796.02 W/m², module temperature of 39.51 °C, operating voltage of 31.62 V, operating current of 20.03 A, and output power of 651.18 W. The average measurement-point efficiency was 15.47%, while the efficiency calculated from average parameters was 15.67%. The estimated energy during six hours was 3.91 kWh, with a specific yield of 3.91 kWh/kWp, performance ratio of 81.8%, and estimated performance loss of 18.2%. These results indicate that the system can contribute as energy capacity expansion, but cannot yet be claimed to meet the entire daily energy demand.
