Abstrak
Muna has extensive agricultural and plantation land potential. However, most of these areas still lack adequate access to electricity because they are located in remote regions. An off-grid photovoltaic system provides an effective solution for independent electricity generation and offers several advantages, including environmental sustainability, cost-effectiveness, and long-term operation. This study developed a rooftop off-grid Photovoltaic system for application in corn plantations in Muna. The proposed system is capable of supplying an electrical energy demand of 120 Wh/day to power two 5W LED lamps for plantation lighting. Under clear weather conditions, the solar panel generates approximately 128Wh/day with an average system efficiency of 80–85%. A 12V, 32Ah lead-acid battery provides sufficient storage capacity, with a daily energy requirement of only 12.9Ah. Experimental results indicate that the battery voltage remains stable within the range of 12.2–14.1V during both charging and discharging processes. The 220W inverter also operates stably under a total load of 10W without experiencing voltage drops or excessive heating. Daytime performance testing showed that the maximum solar panel voltage and current occurred between 12:00 and 13:00, producing an output power of 32.4W, which is close to the panel's rated capacity of 32 Wp. Overall, the proposed off-grid PV system demonstrated reliable and efficient performance, making it suitable for providing lighting in small-scale corn plantations in Muna.
