Description
技术领域 technical field
本发明涉及光伏领域，特别是涉及一种带有最大功率点跟踪技术的超薄高效太阳能组件。 The invention relates to the field of photovoltaics, in particular to an ultra-thin and high-efficiency solar module with maximum power point tracking technology.
背景技术 Background technique
早在1839年，法国科学家贝克雷尔（Becqurel）就发现，光照能使半导体材料的不同部位之间产生电位差。这种现象后来被称为“光生伏特效应”，简称“光伏效应”。 1954年，美国科学家恰宾和皮尔松在美国贝尔实验室首次制成了实用的单晶硅太阳电池，诞生了将太阳光能转换为电能的实用光伏发电技术。 20世纪70年代后，随着现代工业的发展，全球能源危机和大气污染问题日益突出，传统的燃料能源正在一天天减少，对环境造成的危害日益突出，同时全球约有20亿人得不到正常的能源供应。这个时候，全世界都把目光投向了可再生能源，希望可再生能源能够改变人类的能源结构，维持长远的可持续发展，这之中太阳能以其独有的优势而成为人们重视的焦点。丰富的太阳辐射能是重要的能源，是取之不尽、用之不竭的、无污染、廉价、人类能够自由利用的能源。太阳能每秒钟到达地面的能量高达80万千瓦时，假如把地球表面0.1%的太阳能转为电能，转变率5%，每年发电量可达5.6×1012千瓦小时，相当于世界上能耗的40倍。正是由于太阳能的这些独特优势，20世纪80年代后，太阳能电池的种类不断增多、应用范围日益广阔、市场规模也逐步扩大。 20世纪90年代后，光伏发电快速发展，美国、德国、日本、中国、瑞士、法国、意大利、西班牙、芬兰等各个国家纷纷出台各种补贴政策来促进光伏发电行业的发展。 As early as 1839, the French scientist Becqurel discovered that light can generate potential differences between different parts of semiconductor materials. This phenomenon was later called the "photovoltaic effect", or "photovoltaic effect" for short. In 1954, American scientists Chapin and Pearson made a practical monocrystalline silicon solar cell for the first time at Bell Laboratories in the United States, giving birth to a practical photovoltaic power generation technology that converts sunlight energy into electrical energy. After the 1970s, with the development of modern industry, the global energy crisis and air pollution problems have become increasingly prominent. Traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more prominent. At the same time, about 2 billion people in the world do not have access to normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings. The energy of solar energy reaching the ground every second is as high as 800,000 kilowatt-hours. If 0.1% of the solar energy on the earth's surface is converted into electrical energy, the conversion rate is 5%, and the annual power generation can reach 5.6×1012 kilowatt-hours, which is equivalent to 40% of the world's energy consumption. times. It is precisely because of these unique advantages of solar energy that after the 1980s, the types of solar cells have continued to increase, the scope of application has become increasingly broad, and the market scale has gradually expanded. After the 1990s, with the rapid development of photovoltaic power generation, the United States, Germany, Japan, China, Switzerland, France, Italy, Spain, Finland and other countries have introduced various subsidy policies to promote the development of photovoltaic power generation industry.
目前市场上的太阳能电池组件一般设置于住宅或大厦等的建筑物而暴露于风雨中。太阳能电池组件，由于是在这样的严酷的环境下使用的产品，所以相对于风载荷或积雪载荷的强度是表示产品品质的指标之一。近年来，为了降低每单位输出的价格，或者为了缩短施工作业所花费的时间以及接线作业所花费的时间，而推进太阳能电池组件的大型化和轻量化。 Solar cell modules currently on the market are generally installed in buildings such as houses or buildings and are exposed to wind and rain. Since solar cell modules are used in such a severe environment, the strength against wind load or snow load is one of the indicators of product quality. In recent years, solar cell modules have been increased in size and weight in order to reduce the price per unit of output, or to shorten the time required for construction work and wiring work.

请参阅图1-图3，本发明实施例包括： Please refer to Fig. 1-Fig. 3, the embodiment of the present invention comprises:
一种带有最大功率点跟踪技术的超薄高效太阳能组件，包括：玻璃层1、太阳能电池片组件2、太阳能背板3和接线盒4。 An ultra-thin and high-efficiency solar module with maximum power point tracking technology, comprising: a glass layer 1 , a solar cell assembly 2 , a solar backplane 3 and a junction box 4 .
所述玻璃层1、太阳能电池片组件2、太阳能背板3和接线盒4依次设置，所述太阳能电池片2组件通过焊带电性连接所述接线盒4，所述焊带表面设置有反光膜，通过在焊带上增加反光膜，改变焊带表面结构，使得太阳能电池片组件2增加光照吸收，进一步提高太阳能组件转换效率，反光膜的宽度一般略大于焊带的宽度，确保反光膜完全覆盖焊带，加入反光膜技术，CTM有明显增益，增益至少在1.4%，同时保证生产出的组件可以顺利通过可靠性测试项目，如热斑耐久测试、热循环（200）测试+反向电流过载测试、DH1250测试、温度测试以及UV90KWH等，所述玻璃层为厚度小于3.2mm的钢化玻璃，所述接线盒4采用最大功率点跟踪接线盒。通过对阵列中每块电池板分布式安装最大功率跟踪模块，使电站仿真中每块板始终工作在最大功率输出点。当阵列中的组件被建筑、云、树等阴影遮挡、自身出现失配情况时，由于二极管的作用部分电池会被旁路掉，从而减低了整个组件阵列的发电总量。采用最大功率点跟踪技术对太阳能电池组件为单位进行控制，使其在MPP状态下工作，在以上情况发生时与之前比较可提高发电量。 The glass layer 1, the solar cell assembly 2, the solar back panel 3 and the junction box 4 are sequentially arranged, and the solar cell 2 assembly is electrically connected to the junction box 4 through a welding strip, and a reflective film is provided on the surface of the welding strip , by adding a reflective film on the welding strip, changing the surface structure of the welding strip, so that the solar cell module 2 increases the light absorption, and further improves the conversion efficiency of the solar module. The width of the reflective film is generally slightly larger than the width of the welding strip to ensure that the reflective film is completely covered Soldering ribbon, adding reflective film technology, CTM has obvious gain, the gain is at least 1.4%, and at the same time ensure that the produced components can successfully pass the reliability test items, such as hot spot durability test, thermal cycle (200) test + reverse current overload test, DH1250 test, temperature test and UV90KWH, etc., the glass layer is tempered glass with a thickness less than 3.2mm, and the junction box 4 adopts a maximum power point tracking junction box.
