Abstract

The growing demand for sustainable communication infrastructure has increased interest in alternative display technologies capable of operating efficiently under limited grid availability. This study presents the development and performance evaluation of a standalone solar-powered LED display system designed for low-energy, real-time information dissemination in outdoor and semi-outdoor environments. The system integrates a 128 × 48 pixel P10 LED matrix, an Arduino Nano-based control unit, wireless communication capability, and a photovoltaic power subsystem with battery storage to support autonomous operation. System sizing was based on load characterization and renewable energy design considerations to ensure reliable off-grid performance. Experimental evaluation showed that the display operated at an average power consumption of 45.2 W during scrolling text operation, representing approximately 62.3% and 85.3% reductions in energy consumption compared with conventional fluorescent and incandescent display systems, respectively. The photovoltaic subsystem achieved an energy generation-to-consumption ratio of 4.9:1 with a battery backup duration of approximately 14.5 h under normal operating conditions. Wireless communication tests demonstrated a maximum transmission range of 45 m with 100% successful message update transmission and an average latency of 2.3 s. In addition, the display maintained stable 60 Hz refresh operation with satisfactory brightness uniformity and clear text visibility at viewing distances up to 10 m. The results demonstrate that the proposed system provides a reliable, scalable, and energy-efficient solution for sustainable information delivery in regions with unstable electricity supply and high solar energy potential.
