<![CDATA[The use of electric sprayers for pesticide application in Jipang Village, Blora, faces challenges due to battery dependency, often leading to inefficiencies when batteries deplete mid-operation. This study evaluates the performance of a hybrid sprayer integrated with a 10W monocrystalline solar panel and a Pulse Width Modulation (PWM) charge controller to optimize field battery charging. Experimental methods included measuring solar irradiance (using a lux meter), voltage, current, and system efficiency across three days (21 May, 29 May, and 1 June 2025) at hourly intervals (08:00–16:00 WIB). Results indicate peak efficiency (15–18%) during morning hours (08:00–10:00 WIB) under high irradiance (900–1045 W/m²), while afternoon efficiency dropped to 7–13% due to declining sunlight intensity and suboptimal solar angles. The highest power loss (60–71W) occurred at 09:00–10:00 WIB, attributed to energy conversion limitations. The study concludes that solar-hybrid sprayers are viable for agricultural use, provided battery charging is prioritized in the morning. This solution enhances operational efficiency while reducing carbon emissions and fossil fuel reliance.]]>
