双玻光伏组件和常见的玻璃太阳能板有什么区别?

幻启太阳能科技 11/21/2022

太阳能电池组件结构中的第一层材料,钢化玻璃可以有效地保护电池板和太阳能电池免受物理应力、雪、风、灰尘和水分等的影响,同时保证阳光可以照射进来。双玻光伏组件指由两片玻璃和太阳能电池片组成复合层,电池片之间由导线串、并联汇集到引线端所形成的光伏电池组件。而现有的玻璃太阳能板背面一般有一块不透明的板材保护,称为背板。整个结构由铝制框架结构固定,在安装过程中提供强度,防止意外和误操作。换句话说,从外观上看双玻光伏组件将现有的太阳能板背面材质改为了玻璃。

双玻光伏组件和现有的玻璃太阳能板优缺点:

对于传统的太阳能电池板,当雪变厚或人们踩在上面时(在安装过程中),太阳能电池会明显弯曲,从而导致电池上出现微裂缝。由于两层玻璃带来的强度增加,太阳能电池的变形将大大减少,在太阳能电池上形成微裂缝的可能性将大大降低。塑料背板(单层玻璃太阳能组件的背板材料)相比,玻璃是无反应的。这意味着,双玻太阳能电池组件的整体结构(两层玻璃,中间一层太阳能电池)具有很强的抗化学反应能力,如整体腐蚀。

但是相对于传统的太阳能板,双玻光伏组件的造价是更高的,不单单是价格,还有不良率的成本。双玻光伏组件特别容易在层压时出现气泡。因为双面都是玻璃,固定比较困难,里面固体胶在经过层压机的高温,变成液态时,容易发生滑动,发生位移现象。其次双玻光伏组件重量是高于单面玻璃组件的,对于重量有要求的,那么这个也是致命伤害。
