Abstract：Based on local policies on building photovoltaics in Shanghai,the determination method for installation area of building PV in Shanghai is analyzed;technical measures proposed during the study and preparation of the revised edition of local standard Code for Fire Proofing Design of Electric in Civil Buildings are introduced,including the protection methods for PV DC arc,the design of module‑level rapid cut‑off system for fire rescue,as well as the selection of building PV materials and installation site and the requirements for maximum voltage limit.

Key words：renewable energy;conventional energy;initial generating efficiency;DC arc;series arc;parallel arc;arc to earth;module‑level rapid cut‑off

摘　要：从上海建筑光伏的地方政策入手，分析上海建筑光伏安装面积的确定方法；介绍在上海地方标准《民用建筑电气防火设计规程》修订版的研编过程中，提出的光伏直流电弧的防护方法、消防救援时组件级快速关断系统的设计，以及建筑光伏材质和安装位置的选择、最大电压限值的要求等技术措施。
