This study aims to analyze many efficiency-enhancing and improvement activities such as manual and natural cleaning, a PV power plant type rainwater harvesting system, thermal monitoring, and snow load removal in a 600 kW grid-connected photovoltaic (PV) power plant. The study shows that up to 5.66% power reduction can occur for PV modules that have been dirty for close to one year. It was determined that the dust removal effect of the rain was up to 0.94%. This study showed that the potential for collecting rainwater from a small part of the PV plant is approximately 118 m³/year and that the harvesting system will reach 1646 m³/year when applied to the whole plant. A snow load of 0.117 kN per m² was removed. On the basis of three days, 50–75% higher energy production was achieved compared to the other power plant with snow load. Snow removal on PV arrays both prevented PV degradation and resulted in increased power generation, while panel cleaning improved energy efficiency. This study an innovative approach with rainwater harvesting from solar power plants with large surface area for the use in panel cleaning and agriculture of the obtained water, which is a novel idea in increasing the efficiency of the power plants, combating climate change and drought.

本研究旨在分析 600 kW 并网光伏 (PV) 电站中的许多提高效率和改进活动，例如手动和自然清洁、光伏电站式雨水收集系统、热监测和雪负荷去除。研究表明，对于已脏污近一年的光伏组件，最多可降低 5.66% 的功率。经测定，雨水除尘效果高达0.94%。该研究表明，从光伏电站的一小部分收集雨水的潜力约为118 m ³ /年，当应用于整个电站时，收集系统将达到1646 m ³ /年。0.117 kN/m ^{2 的}雪荷载去掉了。在三天的基础上，与其他有雪荷载的发电厂相比，实现了 50-75% 的高发电量。光伏阵列上的除雪既防止了光伏退化，又增加了发电量，而面板清洁则提高了能源效率。本研究采用从大表面积太阳能发电厂收集雨水的创新方法，用于面板清洁和获得的水的农业，这是提高发电厂效率、应对气候变化和干旱的新想法。
