光伏 组件 的 思考 The Thoughts on PV Modules 2019 | 06 施正荣 博士 Dr. Zhengrong Shi 光伏产品历史价格 Historical price of solar product 如何降低光伏组件成本? How to cut the cost of PV Modules? ⚫ 减少投资,提高生产效率 —— 已实现国产设 备代替进口设备,自动化产线代替手工操作 ⚫ Reduced investment, improved production efficiency—— locally made equipment & automated production lines ⚫ 扩大产量,利用规模效应 —— 产量需有数量 级增长,且成本下降有限 ⚫ Enlarged production to massive scale— limited cost down resulted from scale of economy ⚫ 提高光电转换效率 —— 晶体硅电池和组件转换效率已接近理论上限 ⚫ Improved the photovoltaic efficiency— the photovoltaic efficiency of module is approaching to the ceiling 如何降低光伏组件成本? How to cut the cost of PV Modules? 几十年前的光伏组件,电池价格远高于封装材料 Cell cost was much higher than lamination materials in PV module several decades ago ➢ 玻璃前板 ➢ Glass top ➢ 塑料背板 ➢ Plastic Back sheet ➢ 铝边框 ➢ Aluminium frames • 组件的重量 =20 kg • Weight of solar panel = 20 kg • 电池的重量 =720 g • Weight of solar cells = 720 g • 仅仅 3.6% • Only 3.6% • 组件的厚度 =40 mm • Thickness of panel = 40 mm • 电池的厚度 =0.5 mm • Thickness of cell = 0.5 mm • 仅仅 0.0125% • Only 0.0125% 现在封装材料价格超过电池 The price of lamination materials overtaking that of cell right now 组件结构如何变化? How will the module structure continue to change? ⚫ 叠瓦组件(图自 1966年专利) ⚫ Shingled module (pic from patent 1966) ⚫ 双玻(双面)组件 ⚫ Double glass(bifacial )module ⚫ 半片组件 ⚫ Half-cell module 封装材料还可以再降价吗? Will the price of lamination materials be reduced further? ⚫ 沪铝 价格( 2012.9-2019.4) ⚫ Al in SHFE ( 2012.9-2019.4) ⚫ 玻璃( 2012.12-2019.4) ⚫ Glass in ZCE ( 2012.12-2019.4) ⚫ 沪铜( 2012.9-2019.4) ⚫ Cu in SHFE ( 2012.9-2019.4) ⚫ 沪锡( 2015.3-2019.4) ⚫ Sn in SHFE ( 2015.3-2019.4) 不能降价的材料,可以替换吗? Can we replace the lamination materials? ⚫ 树脂背板 ⚫ Resin backsheet ⚫ 铝背板 ⚫ Al backsheet ⚫ 塑料背板 ⚫ Plastic backsheet ⚫ 玻璃背板 ⚫ Glass backsheet eArche采用自主知识产权材料,代替玻璃和背板,省去铝边框 eArche adopts patented material to replace glass and backsheet and to save frame 光学性能 Optics 发电性能 Performance 安装便捷 Easy installation 绝缘性能 Insulation 机械性能 Mechanical 耐久性能 Durability 安全性能 Safety 可信任 Accreditation 外形美观 Aesthetics 回收性能 Recycle 专利工艺 proprietary process 专利材料 proprietary material 晶体硅薄柔组件 ultra thin and flexible c- Si module 绝缘性能 I s lation 机械性能 c ic l 保证组件低价的同时,追求综合性价比 Ensure the module cost as well as the system cost ⚫ 易于搬运,减少包装、运输和人工成本 ⚫ Easy to handle, reduced packing, transport and labor cost ⚫ 工程产品化,定制生产,减少现场施工 ⚫ From engineering to product, tailor made and reduced on site installation cost 国际认证和获奖 International certifications and award
