Maintenance and Refinement of Solar Signposts on a School Campus

Abstract

Following global warming and the recent energy crisis, schools at all levels have built several types of green energy facility to achieve educational and promotional goals. It was observed that electronic signs powered by solar energy (solar signposts) and lighting systems on campus could no longer function normally after an average of 2–3 years, resulting in waste. To alleviate this situation, the solar signpost system of this school was tested and repaired, and maintenance was completed to ensure that functions were normal. To refine the system, after data collection and analysis as well as considering human factors engineering, a battery and controller were installed in a location where they could be easily tested and repaired. In an overall review, green energy systems must undergo regular maintenance and testing for systems to function normally; they also enable students to obtain relevant knowledge and capabilities.
