Abstract：
Focused on the influence of heat from photovoltaic modules on building envelope’s heat transfer and energy saving performance, and the power generation of photovoltaic system affected by many factors, the coupling mechanism of power generation and heat transfer of photovoltaic modules on building exterior wall, the influence of solar incident angle and other factors on photovoltaic power generation performance, and the synergy of solar energy generation and building energy consumption are studied in this paper. The installation method of photovoltaic modules on exterior wall with optimal comprehensive energy saving performance is presented. An optimization design software for building solar system is developed and applied to the Zero Emission Building (ZEB) of China Academy of Building Research, which demonstrates the way to realize zero carbon building by integration of photovoltaics. The total installed power of the photovoltaic system in the ZEB is 236.1 kW. Monitoring data shows that the annual power generation of the ZEB could reach 212 382 kWh, and the power generation per building area is 73.79 kWh/m2. It can not only meet the total energy demand of the building, but also supply extra power to surrounding buildings, and achieve net zero carbon emission.
