【摘要】：太阳能增透型自清洁玻璃可以提高光伏电池的发电效率、减少人工清洗费用、缩短电站并网发电的成本回收时期、提高其市场竞争力。本文分析了玻璃的外表面灰尘和污垢对光伏组件影响,高频率的电站后期维护和清洁工作造成的成本,不但导致光伏发电项目后期的损失变大,而且还会影响到组件的正常使用寿命。本文分析了增透型自清洁膜层具有优良的增加入射光透光率和提升太阳能电池片功率的性能的原因。研究了膜层在正常镀膜完成后的性能,光伏透射比平均可达到93%,对表现出超强的亲水性、超强的抗沙尘黏附能力和超强的分解有机物能力,通过以上三种性能作用的发挥,怎样有效减少各类光伏电站组件玻璃表面的灰尘、有机污染物,继而怎样给光伏电站带来更多收益进行了探讨。通过喷涂法进行SSG玻璃制备并对其进行定型试验,通过GB/T 30984.1-2015、IEC61215、IEC61730、JC/T2423等标准的可靠性试验验证,包括光射比、膜层硬度、光解指数、耐磨性能、耐紫外辐照性能、耐热循环性能、耐湿热性能等全面的检测项目。给出了膜层有优异光学性能和耐候性能的结论。对喷涂、辊涂工艺进行了探讨,对已建成电站进行技术改造一般采用前一种模式。通过合理的配置设备的移动速度,喷枪的数量、间距,以及选择作业环境条件,来保证增透型自清洁纳米膜层的镀膜效果优异;对新建电站,在组件终检下线后,安装辊涂产线从而立即完成增透型自清洁纳米膜层的辊涂工作。直接在光伏玻璃表面辊涂膜层。在现有的标准中无法明确应用新技术后将对发电量的增益,为了解决因发电量增益带来的商务争端等事宜,对于已技改完成的电站,进行数学分析,研究了在合理误差范围内选取最佳电量统计方案,为后续业务开展提供理论依据,特制定对比方阵与参考方阵选取的原则和增益计算方法。
[Abstract]:Solar antireflection type self-cleaning glass can improve the efficiency of solar photovoltaic cells, reduce the manual cleaning cost, shorten the period of cost recovery in power plants and power generation, to improve its market competitiveness. This paper analyzes the influence of the outer surface of the glass dust and dirt on the photovoltaic component, the high frequency power station late maintenance and cleaning work cost, not only cause photovoltaic power generation project late loss becomes large, but also affect the normal life of the components. This paper analyzes the type of antireflection has excellent light transmittance and the increase of incident solar cell can enhance performance of power self-cleaning coatings. The coatings were studied in the normal performance of coating after the completion of the average transmission ratio of PV to reach 93%, showing strong hydrophilicity, anti dust adhesion ability of superacids and the decomposition of organic matter, play through the above three kinds of performance function, How to effectively reduce the dust component, glass surface photovoltaic power plant all kinds of organic pollutants, and then discusses how to bring more benefits to the photovoltaic power plant. By spraying SSG glass preparation and carries on the test by GB/T, 30984.1-2015, IEC61215, IEC61730, JC/T2423 and reliability test verification standards, including light, film the hardness, wear resistance, photolysis index, ultraviolet irradiating resistance, thermal cycling performance, resistance detection project comprehensive damp heat performance. Given the film has excellent optical properties and weatherability. The conclusion of spraying, roller coating technology were discussed, the power plant has been built using a general transformation mode. The moving speed of the rational allocation of equipment, gun number, spacing, and working environment, to guarantee the antireflective coating effect type self-cleaning nano coating of excellent; A new power plant, in the final assembly line, the installation of roller coating production line to complete immediately antireflection film and self-cleaning nano coating type. Directly in the photovoltaic glass roller surface coating layer. In the existing standard is not clear and the application of new technology for power generation will gain, in order to solve the problem brought by power gain business disputes and other matters have been completed for technological transformation of power plant, the mathematical analysis, the study selects the best statistical power in a reasonable range of error, to provide a theoretical basis for the subsequent business development, formulated the principle of comparison and reference matrix and gain matrix selection of calculation method.
