“…The electrical and thermal performance of the two types of PV/T collectors was tested in the tropical climatic conditions of Singapore, and a higher performance for the sheet and tube type thermal collector was found, compared to the parallel-plate type thermal collector [139]. The serpentine type PV/T produced 4% higher thermal efficiency, than the header and riser arrangement with uniform fluid flow in the tubes [140]. A 2D steady state energy balance method for a bi-fluid PV/T solar collector, using a serpentine tube configuration was developed and validated, for a range of mass flow rates of water and air [141].…”

“…The air cooling of a commercial PV module configured as a PV/T air solar collector by natural flow, having two low cost modification techniques to enhance the heat transfer to air stream in the air channel, was studied [197]. A novel mathematical model was developed using the "low flow" concept, to determine the optimum thermal absorber plate configuration, with the least material and improved collector efficiency [198]. The optimum water inlet temperature for maximum exergy generation in a PV/T water system was presented based on second law analysis [199].…”

“…Several simulation environments exist to facilitate these modelling efforts, namely TRNSYS (Kalogirou, 2001;Kalogirou and Tripanagnostopoulos, 2006;Zondag et al, 2003), MATLAB/SIMULINK (Silva and Fernandes, 2010), EES (Charalambous et al, 2011) and ESP-r (Cartmell et al, 2004). Among these, we have identified MATLAB/SIMULINK as incorporating the necessary features for the implementation of the proposed trigeneration system model.…”

A solar trigeneration system, based on photovoltaic-thermal (PV/T) collectors, photovoltaic (PV) modules and a heat pump unit for heating and cooling, is modelled to forecast the thermal and electric yields of the system. The aim of the trigeneration system is to provide enough electricity, domestic hot water (DHW), heating and cooling power to meet the typical demand of an urban single family dwelling with limited roof area and allow the household to achieve a positive net energy status. The PV/T collectors and PV modules provide the electricity while the former also powers the DHW component of the trigeneration system. The heating and cooling components rely on a vapour compression cycle heat pump unit powered by electricity. In Fong et al. (2010), solar-powered electric compression refrigeration was found to have the most energy saving potential in subtropical climates. Thus, a heat pump based cooling system is a cost effective solution for residential applications in Lisbon, Portugal. Thus, according to the dwelling's location, construction details and energy demand patterns, the model computes the system's net results by comparing the dwelling demand with the trigeneration system supply. The paper presents a breakdown of the proposed trigeneration system model and describes each component briefly. Preliminary results produced by the model are presented and analysed in order to identify possible ways of improving the overall system performance. IntroductionA trigeneration system is capable of simultaneously generating electricity, heat and cooling power from a single power source. Such a system uses complementary processes to convert the by-products of the main energy conversion and obtain forms of energy which are in line with demand. For instance, a gas-powered turbine driving an electrical generator produces electrical energy and waste heat. The waste heat can be used to produce hot water and power an absorption chiller. The same concept can be applied in solar power plants. Solar radiation is harnessed and converted to heat used to power a turbine which then drives an electrical generator, producing electricity. Heat is an evident by-product of this conversion and can be used for the aforementioned trigeneration system. Also, solar collectors and photovoltaic modules can be used to harness solar energy and convert it to heat and electricity, respectively, which may be used to power several cooling technologies (Fong et al., 2010, Immovilli et al., 2008. The aim of this article is to demonstrate the potential of a solar trigeneration system for the residential sector by describing a model, the methodology that led to that model and analysing a set of preliminary results. Solar Trigeneration System for the residential sectorA turbine-based solar trigeneration system is not suitable for the residential sector due to, among other concerns, scale, size, power rating, initial cost and maintenance. Instead, a solar trigeneration system developed specifically for the residential sector can be envisaged b...

Results of Rahman and Khan (2010) showed that an average increase of 25% in the short-circuit current can be achieved by using mirrors, which is as high as by using sun tracking.…”
