36th European Photovoltaic Solar Energy Conference and Exhibition; 1746-1748, PVSITES project has developed an ambitious set of BIPV solutions specially tailored to provide a comprehensive and robust answer to market demands. One of these solutions is a low concentration PV solution with associated passive climate control properties for building integration in façades and skylights. Glass-glass semitransparent PV modules in conjunction with integrated optical elements are proposed to concentrate solar radiation onto the cells during the central part of the year and allow light passing towards the interior of the building during the winter. At the central part of the year, the lenses deviate solar radiation onto the cells with a double effect: (1) an increase in PV production in comparison with a traditional PV system of same installed power and (2) a reduction in cooling demands due to an enhanced solar control, with less radiation entering the building during the summer. The savings provided by the system are obviously greatly enhanced in locations with high direct irradiation conditions. The system is being demonstrated in three experimental outdoor set-ups with different climates: two experimental test benches in ACCIONA facilities (Seville, Spain), Field Lab Testing facility at Tecnalia site (Derio, Spain) and FACT building at CEA-INES (Chambéry, France).

In the framework of increasingly demanding legislation related to energy performance in buildings, the integration of photovoltaic systems in the building skin offers many possibilities. However, a continuous development of the building-integrated photovoltaics (BIPV) market in the next years necessarily demands the compliance with strict requirements in terms of design flexibility, aesthetics, durability, cost reduction, grid integration, testing standards and operation & maintenance. Within this context, a European consortium of 15 partners is developing the H2020 PVSITES project, “BIPV technologies and systems for large-scale market deployment”. The project will demonstrate an ambitious set of BIPV solutions, specially tailored to provide a comprehensive and robust answer to market demands. This paper focuses on some of the major results achieved at the time of writing. These include a detailed BIPV market and regulatory framework analysis and recommendations for the standardization of BIPV products. Novel developments of glazed crystalline silicon modules for BIPV integration are presented, with both opaque and see-thru variations. Also included are the selection of a battery technology best suited for inclusion in a custom-made building energy management system (BEMS), as well as a BIM-compatible software tool to assist the design of BIPV projects.
