[0002] With the popularization and use of renewable energy, the construction demand for distributed photovoltaic power stations is increasing day by day. When building a photovoltaic power station, a reasonable photovoltaic panel laying scheme is of great significance for improving the power generation efficiency of the power station. Traditional photovoltaic power station equipment planning usually relies on experience or simple models for design, lacking comprehensive consideration of specific geographical and environmental factors, thus highlighting the importance of the photovoltaic panel laying planning for distributed photovoltaic power stations.
