和文要約和文要約等以下本編抜粋:1.共同研究の内容及び成果等 (1)共同研究の内容及び目標値 NEDOが掲げる2020年の発電コストおよび製造コストの目標を実現させるためには、太陽光発電システム全体のデザインを総合的に見直し、太陽電池セル・モジュールに留まらず、据付に関わる部材および工事費用を大幅に低減することが必要である。そこで、本研究では以下を最終目標としている。 (最終目標値~平成26年度) ・機能複合化による部品点数の削減率(50%以上)の達成 ・据付作業人員/時間の低減率(20%以上)の達成 ※但、削減率/低減率については、平成24年度までに妥当性を検証し、目標値を設定する。 ・新規開発した機能複合化部品および軽量モジュール構成を組み合わせた太陽光発電システムの耐久性実証(IEC61215準拠耐荷重試験、降雹試験)
英文要約Title: New Technology Development for Reducing Photovoltaic Module Installation Cost (FY2010-FY2012) FY2010 Annual Report
In order to achieve grid parity, it is necessary to work on reducing total photovoltaic system cost/Wh. The total photovoltaic system cost consists of module, BOS, and installation. To achieve significant cost reduction of total photovoltaic system, it is required to redesign total photovoltaic system from module to installation. General module with aluminum frame is installed by using metal fixation to fix the module on mounting rack or roof. Aluminum frame contributes to protect from water penetration into inside of module and also mechanically strengthen the module. On the other hand, installation method is limited to require a lot of bolts and nuts to fix module on mounting rack. Furthermore, the bolting work occupies much time in the entire installation time. As one of the way to reduce total photovoltaic system cost, we develop the lightweight thin glass module without aluminum frame so that flexibility is given to the installation method and also develop new installation parts and methods for the module. In 2010, we started developing the technology to reduce module weight and evaluating load property of the module. To evaluate load property of lightweight module, we established a simplified method on a small scale sample with a universal testing machine. By the evaluation method, we selected a reliable encapsulant candidate for thin glass lightweight module. We made 4x7 cell size prototype lightweight module using the selected encapsulant candidate and it passed damp heat test (output loss is less than 5% after exposure of 85C x 85%RH x1000hr). The module weight is less than 50% compared with the conventional glass/glass structure module. Based on the frameless module, we created a prototype of multi-functional composite parts for easier installation. We estimated that the new installation method using the parts has the possibility of reducing the number of parts by 50% from conventional installation method. The material of the multi-functional composite parts will be selected by evaluating material durability such as UV resistance and hydrolysis resistance. Furthermore, we will analyze the material degradation mechanism after exposure of UV and damp heat conditions.
