Advances in building-integrated photovoltaic (BIPV) systems for residential and commercial purposes are set to minimize overall energy requirements and associated greenhouse gas emissions. The BIPV design considerations entail energy infrastructure, pertinent renewable energy sources, and energy efficiency provisions. In this work, the performance of roof/façade-based BIPV systems and the affecting parameters on cooling/heating loads of buildings are reviewed. Moreover, this work provides an overview of different categories of BIPV, presenting the recent developments and sufficient references, and supporting more successful implementations of BIPV for various globe zones. A number of available technologies decide the best selections, and make easy configuration of the BIPV, avoiding any difficulties, and allowing flexibility of design in order to adapt to local environmental conditions, and are adequate to important considerations, such as building codes, building structures and loads, architectural components, replacement and maintenance, energy resources, and all associated expenditure. The passive and active effects of both air-based and water-based BIPV systems have great effects on the cooling and heating loads and thermal comfort and, hence, on the electricity consumption.

“…In these systems, the heat produced from the PV/T is fed into the heat pump evaporator. The process is outlined: (1) direct expansion of the refrigerant from liquid to vapour, taking place inside the hydraulic circuit of the PV panels, (2) vapour compression for heating purposes, (3) refrigerant is condensed for heat transfer to water, (4) expansion valve (or capillary tube) used to turn high-pressure refrigerant to low-pressure liquid for reinsertion into PV/T evaporator (Riaz et al, 2020). Although this system is more complex than a conventional liquid cooling system, it provides a greater heat transfer from the PV to the working fluid than the prementioned systems, allowing for greater thermal and electrical efficiencies.…”

Hybrid photovoltaic/thermal systems have become an important energy technology due to their capacity of producing electrical and thermal energy simultaneously, their ease of integration into buildings and good overall performance. Conventional PV systems generate waste energy in the form of heat during the conversion of solar radiation into electricity. It has been shown that the electrical efficiency of PV panels decays with the rise in the PV cell temperature. Therefore, PV performance can be optimised if this heat is removed. Air and water are the most common media used for heat removal and the energy can then be used for heating applications in buildings. In the last five decades, researchers worldwide have carried out experimental studies, simulations and numerical modelling of different types of PV/T systems. In addition to water and air, heat removal methods such as refrigerants, PCM, heat pumps and nanofluids have been analysed. This work presents an overview and discussion of the research of the different PV/T thermal control systems of the last five years. The present study highlights key points of the different techniques that exist, such as overall efficiencies, parameters and configurations, type of system, the nature of work, country of development and applications. Based on this study, it was concluded that the PV/T systems are auspicious technology and that further work should be focused on the aesthetics of the systems to promote acceptance and improvement of the efficiency.

“…Since, the hybrid system utilizes same area for the production of electricity and heat energy, it increases the overall efficiency of the system in terms of energy generation from per unit area [5]. The solar PVT system can be used for crop drying and air heating, and it can also be integrated with building facade, known as the building integrated PVT system (BI/PVT) [6]. The theoretical calculation says that the overall energy conversion efficiency of a hybrid system could be 60-80% [7].…”

Solar photovoltaic (PV) and solar thermal systems are most widely used renewable energy technologies. Theoretical study indicates that the energy conversion efficiency of solar photovoltaic gets reduced about 0.3% when its temperature increases by 1°C. In this regard, solar PV and thermal (PVT) hybrid systems could be a solution to draw extra heat from the solar PV panel to improve its performance by reducing its temperature. Here, we have designed a new type of heat exchanger for solar PV and thermal (PVT) hybrid systems and have studied the performance of the system. The PVT system has been investigated in comparison with an identical solar PV panel at outdoor condition at Dhaka, Bangladesh. The experiments show that the average improvement of open circuit voltage (Voc) is 0.97 V and the highest improvement of Voc is 1.3 V. In addition, the overall improvement of output power of solar PV panel is 2.5 W.
