Active solar technologies

Abstract

This chapter presents a summary of active solar technologies employed to convert solar radiation into thermal and electrical energy, to be utilized in various building applications including space heating, domestic hot water, and to meet various electrical requirements. Active solar technologies include various types of photovoltaic (PV) technologies (such as different PV cells, semi-transparent PV, transparent PV, and others), hybrid PV/thermal collectors, and solar thermal collectors. Current advancements in these technologies are summarized. In addition, the methods of integration of these technologies into buildings and especially the building envelope are discussed. The main criteria for successful integration and performance of these technologies are highlighted.
