技术领域technical field

背景技术Background technique

太阳能作为一种可再生能源,拥有清洁、环保等优势,被人们广泛应用。太阳能光伏发电系统多位于太阳能资源丰富、土地利用率低、无遮挡物的位置,通常情况下伴随沙尘富集、多风的特点,随着时间的推移风中夹带的沙、尘会在光伏组件表面沉积,这将会影响光伏组件上玻璃盖板的反射率和透过率,从而降低太阳能光伏组件的光学转换效率。长年累月下来会对光伏组件表面产生磨损,从而对光伏组件光学性能及寿命产生不利的影响。在长期使用中难免落上飞鸟、尘土、落叶等遮挡物,被遮蔽的太阳电池组件此时会发热,产生热斑效应。这种效应能严重的破坏太阳电池,降低其光电转换率、减少太阳能电池板的使用寿命。As a renewable energy source, solar energy has the advantages of cleanliness and environmental protection, and is widely used by people. Solar photovoltaic power generation systems are mostly located in locations with abundant solar energy resources, low land utilization rate, and no shelter. Usually, with the characteristics of sand and dust enrichment and windy conditions, the sand and dust entrained in the wind will accumulate in the photovoltaic Deposition on the surface of the module will affect the reflectivity and transmittance of the glass cover on the photovoltaic module, thereby reducing the optical conversion efficiency of the solar photovoltaic module. Over the years, the surface of the photovoltaic module will be worn, which will have a negative impact on the optical performance and life of the photovoltaic module. During long-term use, it is inevitable that flying birds, dust, fallen leaves and other shelters will fall on them. At this time, the shaded solar cell modules will heat up, resulting in hot spot effect. This effect can seriously damage the solar cell, reduce its photoelectric conversion rate, and reduce the service life of the solar cell panel.

针对前面的情况,目前解决的方法有:1、采用人工洒水清洗,缺点是浪费水资源、浪费人力且速度慢;2、智能机器人清洗太阳能电池板,缺点是成本高、效率低,可靠性低;3、目前的太阳能清洗系统清洁力度低、利用度不高。本发明针对现有技术的不足,提出了一种太阳能电池板灰尘检测及清洁系统。In view of the previous situation, the current solutions are: 1. Using artificial watering to clean, the disadvantages are waste of water resources, waste of manpower and slow speed; 2. Intelligent robot cleaning solar panels, the disadvantages are high cost, low efficiency and low reliability ; 3. The current solar cleaning system has low cleaning power and low utilization. Aiming at the deficiencies of the prior art, the invention proposes a solar cell panel dust detection and cleaning system.
