Abstract The energy benefits of integrating PV panels with dynamic overhangs are evaluated for US residential buildings. Various control strategies are investigated to operate the dynamic overhangs to minimize annual net energy demands to account for both building energy needs and PV electricity generation yields. The analysis results indicate that dynamic overhangs can reduce significantly the annual energy demand for US residences compared to no-overhang and static overhang options even when controlled on a monthly basis and without any PV panels. Specifically, it is found that dynamic overhangs applied to southern facing windows for houses located in Golden, CO, can save up to 6% when no-PV array is installed and more than 35% when integrated with PV panels using monthly adjustments. Even higher savings up to 90% can be achieved for houses located in warm climates and those with larger windows. Moreover, PV-integrated dynamic overhangs can provide energy savings for windows oriented in any direction especially when adjusted on daily basis.
