“…The heat pump nominal heating capacity and COP are equal to 8.52 kW and 3.19 respectively, whereas PV/T module performance feature commercially available ones (SoLink, 2017). The HP is modelled in MATLAB ® considering the governing equations of each component as detailed in the next section, whereas the PV/T are modelled combining datasheet information and experimental measurements carried out at SolarTech Lab of Politecnico di Milano (Bombarda, et al, 2016).…”

This work summarizes the performance of a Solar Assisted Heat Pump integrating Photovoltaic thermal (PV/T) modules. This configuration reduces the disadvantage of low temperature heat recovery typical of PV/T modules as the fluid temperature is used to drive the heat pump evaporator instead of an end-user and, consequently, can be close to the ambient one. A detailed model featuring real components is developed in MATLAB ® to correctly predict the SAHP performance as function of the design parameters (number of PV/T modules) and ambient conditions (solar irradiance and ambient temperature). In addition, an optimization tool was combined with the model to maximize the COP (Coefficient of Performance) by varying the water flow rate circulating in the PV/T panels. Results outline the benefits of this concept with respect to conventional air/water heat pumps in particular when the ambient temperature is below zero as the frost formation issue is not present. COP reaches high values, between 2.5 and 4.9 in the case with 12 PV/T panels and between 2.2 and 6.2 with 24. Advantages in terms of electricity production are outlined as well, with an increasing of 8-9% of the power produced.

“…The ambient temperature also has an effect on the power output: As the operating temperature increases, the efficiency of the PV cells drops. Another definition for the thermal efficiency was proposed by Bombarda et al [28]. Here, a distinction is made between the electrical and thermal power of the system, and thus the electrical power production is subtracted from the total incident irradiation.…”

Photovoltaic-thermal (PVT) panels combine solar thermal and photovoltaic technologies and generate simultaneously both heat and electricity. This paper looks at the potential of integrating these systems into small domestic prosumer households for the climates of Bucharest, Romania, and Strasbourg, France. First, some brief background information on PVT systems and the concept of prosumers is introduced, highlighting their features as well as the solar energy market setting in Romania and France. Next, a PVT system is proposed for a given household consumer in Strasbourg and Bucharest with the variable weather conditions corresponding to the two locations. The PVT system and the coupled consumer are modelled in TRNSYS (v17, Thermal Energy System Specialists, Madison, USA). A performance analysis is carried out in order to establish the daily instantaneous energy output and the annual energy production. The results indicate a 10–12% better performance in Bucharest compared to Strasbourg due to slightly better weather conditions. The system efficiency was assessed through various methods (first law efficiency and primary energy saving). Depending on the method used, the location and time of year, the results vary from 15% for the first law efficiency to 90% for the primary energy saving efficiency. The most suitable efficiency assessment method for this study was found to be the primary energy saving method, as it takes into account the regional differences in energy production. This study concludes that the Romanian PVT market has a good potential for adopting the technology, especially since it is currently less mature than in France.

“…The SAHP concept consists of solar collectors which can either solar thermal collectors or hybrid Photovoltaic/Thermal (PV/T) providing the heat to the evaporator. Between solar thermal modules and PV/T, the former guarantees higher thermal collection while the latter combines electricity and heat production, with benefits for the solar cells efficiency (Bombarda et al, 2016).…”
