Using PV to help meet common property energy demand in residential apartment buildings

摘要: 14% of Australians live in apartments, predominantly urban centres, yet few these have PV systems,despite high levels deployment on separate and semi-detached residential buildings. Increased PVdeployment apartment buildings represents a valuable market opportunity for the industry, which wouldallow dwellers to obtain financial benefits using offset electricity bills. apartmentbuildings could also help relieve network congestion, as it is good fit with commercial loads commonly foundin areas, might therefore benefit operators well households. Some recent high-density developments incorporate system each unit, or anembedded serving all units.
