“…The PVT systems consist of two parts: a solar cell which converts the sunlight into electricity and a solar thermal collector, mounted at the back of the PV panel, for collecting the thermal energy. Water or air are usually applied as the cooling fluids for the solar panels [1,30,31]. Therefore, this configuration enhances the operation of the panels, and improves the efficiency.…”

A main method to increase the solar energy utilization efficiency is to combine heat and power generation together. In this paper, a critical review of the literature on solar combined heat and power systems (CHP) is conducted, which includes solar photovoltaic/thermal systems, concentrated photovoltaic/thermal systems, and various combination with different solar collectors and applications. It shows that there are serious gaps in this field, which calls for more research. The modeling and analysis of the electrical parts of the CHP systems are not adequate, and there are limited studies on the economic and exergy assessments of the solar concentrating CHP systems. The solar collectors for combined CHP were focused on optimizing the performance of the maximum average useful power generation and minimum total heat transfer area, little environment impact analysis was conducted. Careful exergy, economic and environmental analysis on both electronic and thermal performance is suggested, especially for large CHP system.

“…Since the efficiency of a PV panel decreases when the temperature of the cell increases, removing heat from the photovoltaic module by having a fluid flowing through the collector avoids the loss of efficiency. Combining these technologies also alleviates building roof space issues that can occur with separate PV and thermal solar (Dean et al 2015).…”

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.

“…The PV technology converts solar energy into direct-current electricity, which can be later converted into alternate current by using an inverter; this process does not generate any pollution in the usage phase of its life cycle, and the conversion process does not involve any moving parts. The solar modules or panels are usually flat-plate type, and the solar cells constituting these modules can be divided into three main categories: monocrystalline silicon (mono-Si), the less efficient multicrystalline silicon (multi-Si) and thin films, which may employ materials (having various efficiencies) other than silicon [8]. The operating temperature of a solar cell plays a vital role in the conversion process as the efficiency (and power output) of the solar cell decreases linearly with increase in the temperature.…”

This paper reports on a comparative study of the thermodynamic performance of the organic Rankine cycle (ORC) and Kalina cycle 11 (KCS11) using solar energy for application in residential or commercial sectors. The objective was to determine the amount of power that can be produced by solar energy systems using low-quality energy sources (hot water at temperatures above 60 o C), from the viewpoints of the first and second laws of thermodynamics. Moreover, the performance impact of coupling these cycles to hybrid solar photovoltaic-thermal collector systems (PV/T) to increase the total power generation for the same surface area was analyzed. In particular, the PV/T systems were employed to increase the production of solar energy systems, as the efficiency of photovoltaic cells reduces under hot climates, such as the climate in Brazil. The results indicated that the exergy efficiency of the KCS11 is higher than that for the ORC. Nevertheless, both cycles as the bottoming cycles to PV/T collector configurations increased the total theoretical electric power generation, for the design study, in approximately 0.4 kW per unit of area.
