Photovoltaics at ANU

Abstract

Concentrator Systems are an attractive means whereby the cost of PV electricity can be reduced. In a PV/Trough concentrator system most of the solar cells are replaced by a mirror, which costs far less. The few remaining solar cells in the system (at the focal line of the trough) are a relatively small part of total system cost. This means that expensive but efficient cells can be used without economic penalty. A linear parabolic PV concentrator has been developed at the Australian National University in conjunction with several companies, notably Solahart Industries. The system incorporates 2 axis tracking and either water or air cooled receivers. High efficiency ANU concentrator cells have been installed and are working satisfactorily. Show more
