Traditional solar photovoltaic (PV) panels exhibit relatively low conversion efficiency—typically between 5 % and 16 %—mainly due to intrinsic material and optical limitations. To enhance output without using expensive high-efficiency modules, this work investigates a hybrid optical-electronic method that combines Fresnel lens light concentration and an Arduino-based dual-axis tracking mechanism. A compact 50 Wp semi-transparent PV module was integrated with a 9 cm PVC Fresnel lens of 15 cm focal length. The Arduino unit automatically oriented the lens–panel system according to real-time light intensity using dual-sensor feedback. Voltage and current were sampled every 10 s to compute instantaneous power, and experimental trials were carried out for various tilt angles and lens-to-panel spacings. The optimal configuration (20° altitude, 260° azimuth) yielded approximataly119 % increase in instantaneous power (29.7 W vs 13.6 W baseline). Short-term voltage gains of 3.8–6.1 % across multiple days confirmed the repeatability of the result, whereas extended exposure highlighted thermal saturation effects that reduce efficiency, underscoring the need for integrated cooling. Power consumption of the electronics was minimized by a timer-controlled circuit, increasing autonomous operation from 2.5 to 11 days on a 3000 mAh battery. The findings demonstrate that a low-cost Fresnel-lens concentrator combined with autonomous tracking can significantly improve PV performance in small-scale renewable systems, offering a practical approach for decentralized clean-energy generation.
