住宅建筑光伏设计实践

Practice of Photovoltaic Electrical in Residential Buildings

可再生能源利用是国家双碳战略中重要的一环,太阳能光伏发电在其中作用不可或缺。光伏系统设计计算对气象、产品参数依赖度较大,设计人员需要通过查找、比较、计算确定参数。本文通过对光伏系统前期中所涉及的主要产品选型、设计参数的选择及计算,提供一个对规范及公示的理解型式。设计方案最终的确定是多种因素平衡的结果,在方案推敲过程中选用的一些做法,会对光伏系统在住宅建筑中的有效利用造成影响,文中提出一些观点供参考。

The utilization of renewable energy is an important part of the national dual carbon strategy,and solar photovoltaic power generation plays an indispensable role in it.The design and calculation of photovoltaic systems rely heavily on meteorological and product parameters,and designers need to determine parameters through search,comparison,and calculation.The article provides an understanding of standards and public disclosure by selecting and calculating the main products,design parameters involved in the early stage of photovoltaic systems.The final determination of the design scheme is the result of balancing multiple factors.Some practices selected during the scheme deliberation have had an impact on the effective utilization of photovoltaic systems in residential buildings.Some viewpoints are proposed in the article for reference.
