The potential absorption of solar energy in photovoltaic thermal (PVT) hybrid solar collectors at different tilt angles was compared in the present study. The optimal tilt angles were tested in three variants: during 1 day, 1 year and a period of 30 years. Simulations were performed based on actual weather data for 30 years, including average hourly total radiation, insolation and air temperature. The apparent movement of the Sun across the sky, solar radiation properties, and the electrical and thermal efficiency of a PVT collector were also taken into account in the simulation model. The optimal orientation of the absorber surface was determined by solving an optimization task. The results of the study indicate that in the long-term perspective, the collector’s performance is maximized when the absorber is positioned toward the south at an elevation angle of 34.1°.

“…In a typical aerothermal configuration, the air flow behind PV modules is created using air channels, and the heated air is ducted to the point of usage. The use of air as working media is technically simplistic with a potential for lower cost of overall system in comparison to waterbased systems [4]. One interesting aspect of aerothermal is the possibility of converting existing PV installations into PVT collectors, by recovering the heat behind PV modules.…”

Photovoltaic thermal collectors (PVT) can generate electricity and heat from one module. In a typical aerothermal PVT system, the air flow behind the PV modules is created using air channels, and the heated air is ducted to the point of usage. The central aim of this paper is to simulate a system where the recovered heat from a PV installation is utilized in the energy system of a multifamily building cluster in Sweden. The paper tends to establish if the additional cost of "heat recovery system" components justify the savings obtained due to recovered heat from PV. To achieve this, a simulation model is built in TRNSYS for a multi-family building cluster in Sweden. Specifically, two energy system configurations are simulated.1) Recovered heat from PV collectors is used for pre-heating of domestic hot water.2) Heat from PV collectors is used at the evaporator of an air source heat pump to increase its performance. The heat pump is further used to generate domestic hot water.Results show that the advantage of PVT integration is more pronounced when recovered heat is used directly for pre-heating of DHW. The savings are lower when PVT is coupled with heat pump.

“…Several market analyses performed over the last years have shown the market shares of all different PVT collector designs and in different application fields ([D. Zenhäusern et al 2017], [C. de Keizer et al 2017], [M. Adam et al 2015]). Within Subtask A of the IEA SHC Task 60, the statistical data of installed square meters of different PVT collector designs have been gathered and published in Solar Heat Worldwide for the very first time in 2019 [W.

Report B1: This report therefore aims at displaying the Status Quo of PVT Characterization in order to support PVT technology in its further development and applications. The report is hence of interest for researchers as well as public and private sector stakeholders. A key finding is that the reliability and durability of PVT modules are especially challenged at elevated temperatures and higher humidity loads. The test methods available from the IEC and ISO standards are covering the specifics of PV and ST module’s, most of which are similar for PVT modules, too.
