DoubleSun® Performance Across Mainland Portugal

Photovoltaic (PV) technology has been gaining a significant share in Portugal's renewable energy mix. In this paper we focus on the analysis of 29 PV systems (mounted and connected to the grid under the micro‐generation incentive scheme in Portugal), from which 59% are DoubleSun® technology, the remaining being flat‐plate systems. The period in analysis is July 2009–June 2010. A preliminary analysis of the PV systems has confirmed their high potential in Portugal and highlighted the relevance of such analysis to identify: (1) the geographical characterization of PV performance across mainland Portugal; (2) improvement of a tool [1] that predicts the potential of different PV technologies; and (3) the challenges of PV systems when installed on‐field and connected to the grid.
