“…While decarbonisation of the electrical system is on track, the decarbonisation of ST systems has not been tackled. ST systems typically make up about 50% of the final energy demand and [1] suggests that a large portion of the demand could potentially (i.e., while requiring significant technology developments) be supplied by renewable photovoltaic thermal (PVT) solutions. PVT solutions address another important and increasingly emerging issue-spatial and network constraints, thus requiring less space than a PV or ST collector would.…”

The increasing global warming awareness related to climate change due to the high emissions of carbon dioxide in recent decades linked all nations into a common cause, which requires ambitious efforts to combat climate change by adapting energy systems to its effects. This book chapter aims at investigating the potential role of Photovoltaic-Thermal (PVT) solar collector technologies for an urban sustainable development based on the current state-of-art, system components and subsidies for PVT technologies. PVT technologies are a practical solution to compete with isolated systems such as photovoltaic (PV) modules and solar thermal collectors if a significant reduction in manufacturing cost is achieved, coupled with an increased energy production performance. Therefore, its success is intensely linked to the capacity of the PVT industry/researchers to scale down its current system cost and complexity in a way that can shorten the cost/performance gap to both PV and Solar Thermal (ST) technologies. The knowledge gained presented in this book chapter has been acquired through an extensive literature review, market surveys and project development made by several PVT experts with extensive expertise in the development of PVT technologies, which establishes the foundations for more efficient and cost-effective PVT solar collectors.

Photovoltaic thermal (PVT) technology is drawing more and more attention in the context of the energy transition. Electrification of the heating sector by means of heat pumps run by carbon free electricity sources like photovoltaics is setting the ground for the interest. But data is scarce, how well compared to the existing heat pump system designs those with PVT perform. This article shows the real performance data of several PVT plus heat pumps systems. The identified seasonal performance factors (SPF) are in a range from 3,4 to 4,2 therefore between air source and ground source heat pumps. This article gives an insight into PVT technologies and collector designs and structures them according to application and operating temperatures. For the most conventional designs examples such as PVT collector prototypes from R&D projects at Fraunhofer ISE are presented and explained in detail. In addition, commercial products and manufacturers are listed along these categories, and the influence on the gross thermal and electrical yield is depicted based on Solar Keymark certified products and related data. The process of certification along thermal and electric normative procedures is presented in a comprehensive way showing current limitations and giving an outlook on most recent approach for enhanced procedures and specifications. Finally different system layouts are presented and examples from installations combined with a heat pump are given with their specific performances derived under continuous monitoring. The continuous monitoring and derived data are the enabler to discover the decisive influence of the system layout and dimensioning on performance indicators like e.g., operating temperatures of the PVT collectors over the year.This article is protected by copyright.
