Abstract

Taking a villa of 480 m² heating area in Qingdao as the study object, a solar energy and off-peak power hybrid heating system is proposed. In order to operate economically, five operating mode are designed considering the curve of time-sharing price and solar energy. The initial investment, running costs and comprehensive energy price are calculated using the full life-cycle cost theory as a guide. The consumption of off-peak electricity is also analyzed, which modify the peak load shifting contradiction of Qingdao power grid. Comparing with the central heating system, solar energy and off-peak power hybrid heating system has significant economic benefits.
