Abstract:
To improve the energy efficiency of dwellings, rooftop photovoltaic (PV) technology is proposed in contemporary designs; however, adopting this technology will add a new component to the roof that may affect its thermal balance. This paper studies the effect of roof shading developed by solar PV panels on dwellings’ thermal performance. The analysis in this work is performed by using two types of software packages: “AccuRate Sustainability” for rating the energy efficiency of a residential building design, and “PVSYST” for the solar PV power system design. AccuRate Sustainability is used to calculate the annual heating and cooling load, and PVSYST is used to evaluate the power production from the rooftop PV system. The analysis correlates the electrical energy generated from the PV panels to the change in the heating and cooling load due to roof shading. Different roof orientations, roof inclinations, and roof insulation, as well as PV dwelling floor areas, are considered in this study. The analysis shows that the drop in energy efficiency due to the shaded area of the roof by PV panels is very small compared to the energy generated by these panels. The analysis also shows that, with an increasing number of floors in the dwelling, the effect of shading by PV panels on thermal performance becomes negligible. The results show that insensitivity of the annual heating and cooling load to the thermal resistance of rooftop solar systems is only because the total thermal resistance is dominated by roof insulation.

Abstract:
Photovoltaic (PV) modules suffer from a reduction of electric conversion due to the high operating temperatures of the PV cells. Hybrid photovoltaic/thermal (PV/T) technology represents an effective solution for cooling the PV cells. This paper discusses a theoretical study on a novel bi-fluid PV/T collector. One dimensional steady-state numerical model is developed, and computer simulations are performed using MATLAB. This numerical model is based on a pilot PV/T plant, installed in the Campus of the University of Catania, and was experimentally validated. The design of the proposed bi-fluid PV/T is based on a commercial WISC PV/T collector, to which are added an air channel, an aluminum absorber with fins, and a layer of thermal insulation. The analysis of the thermal behavior of the proposed collector is carried out as a function of the flow rate of the two heat transfer fluids (air and water). Finally, the comparative analysis between the conventional water-based PV/T collector, namely PV/T, and the bi-fluid (water/air-based) WISC PVT, namely PV/Tb, is presented for both winter and summer days. For the investigated winter day, the numerical results show an overall improvement of the performance of the bi-fluid PV/T module, with an increase of thermal energy transferred to the liquid side of 20%, and of 15.3% for the overall energy yield in comparison to the conventional PV/T collector. Instead, a loss of 0.2% of electricity is observed. No performance improvements were observed during the summer day.

Abstract:
The PV/T collectors realize the simultaneous output of electricity and thermal energy, which are more efficient than the separated photovoltaic (PV) or solar thermal collectors. In this paper, the electricity generation and thermal collection performances of tube-sheet PV/T collector are studied. The main research contents are as follows: an experimental test system of PV/T collector was built to test the electricity generation and thermal collection performances of tube-sheet PV/T at an inlet water temperature of 30°C. Moreover, the flow resistance test was carried out. In addition, the theoretical heat transfer model was established, and the thermal performance was calculated by theoretical analysis. The experimental data showed that the daily average temperature difference between the PV panel and the inlet water temperature was about 22.5°C. The daily average electrical efficiency was about 9.25%, and the daily average thermal efficiency was about 28.67%. The theoretical analysis of the tube-sheet PV/T model was carried out, and the calculated results were close to the experimental results. The main reason for the large temperature difference between the PV panel and water temperature was that the combined thermal resistance between the PV panel and the absorber plate was large, and reducing the combined thermal resistance could reduce the temperature of the PV panel. The effects of solar irradiance, ambient temperature and spacing of row tubes on the performance of thermal collection were analyzed to optimize the PV/T performance.

Abstract:
The PV/T hybrid system is a combined system consisting of PV panel behind which heat exchanger with fins are embedded. The PV/T system consists of PV panels with a battery bank, inverter etc., and the thermal system consists of a hot water storage tank, pump and differential thermostats. In the present work, the modeling and simulation of a Solar Photovoltaic/Thermal (PV/T) hybrid system is carried out for 5 kWp using TRNSYS for electrical energy and thermal energy for domestic hot water applications. The prominent parameters used for determining the electrical efficiency, thermal efficiency, overall thermal efficiency, electrical thermal efficiency and exergy efficiency are the solar radiation, voltage, current, ambient temperature, mass flow rate of water, area of the PV module etc. The simulated results of the Solar PV/T hybrid system are analyzed for the optimum water flow rate of 25 kg/hr. The electrical efficiency, thermal efficiency, overall thermal efficiency, equivalent thermal efficiency, exergy efficiency are found to be 10%, 34%, 60%, 35% and 13% respectively. The average tank temperature is found to be 50°C.

Abstract:
Several strategies have been developed to enhance the performance of a solar photovoltaicthermal (PV/T) system in buildings. However, these systems are limited by the cost, complex structure and power consumed by the pump. This paper proposes an optimisation method conversion strategy that modulates the ratio of thermal to electrical energy from the photovoltaic (PV) cell, to increase the PV/T system’s performance. The design and modelling of a PV cell was developed in MATLAB/Simulink to validate the heat transfer occurring in the PV cell model, which converts the radiation (solar) into heat and electricity. A linear regression equation curve was used to define the ratio of thermal to electrical energy technique, and the behavioural patterns of various types of power (thermal and electrical) as a function of extrinsic cell resistance (Rse). The simulation results show an effective balance of the thermal and electrical power when adjusting the Rse. The strategy to modulate the ratio of thermal to electrical energy from the PV cell may optimise the PV/T system’s performance. A change of Rse might be an effective method of controlling the amount of thermal and electrical energy from the PV cell to support the PV/T system temporally, based on the energy need. The optimisation technique of the PV/T system using the PV cell is particularly useful for households since they require electricity, heating, and cooling. Applying this technique demonstrates the ability of the PV/T system to balance the energy ( thermal and electrical) produced based on the weather conditions and the user’s energy demands.

Abstract:
The application of double glazed facades, especially in administration buildings is becoming more and more popular. Aside from the architectural aspects, the energetic consequences with respect to the building into which it is integrated have been discussed much over the past few years. In order to quantify the energy balance of such facades, the heat transfer rate between the inner facade layers and the gap temperature are important factors and constitute the core of this thesis. In contrast to experimental estimations of heat transfer rates, which are measured using heat flux sensors, in this study the energy balance within the facade was determined primarily by means of computational fluid dynamics (CFD). For the purpose of verifying the CFD results, simulation results were assessed through comparison with experimental flow data obtained using particle image velocimetry (PIV). Comparison of CFD simulations and PIV measurements showed good agreement for different symmetric and asymmetric plate temperatures as well as for different forced flow rates. A new Nusselt correlation was developed, which was derived from a CFD parameter study. The suggested correlation includes plate distances which vary from 0.05 to 0.5m, surface temperatures from -10 to 60 degrees C, inlet temperatures from -10 to 30 degrees C and Reynolds numbers (Red) between 500 and 6500. In order to estimate the thermal behaviour of a ventilated facade at an early stage of building planning, a transient simulation program was developed which is able to calculate the dynamic energy balance that occurs in a double facade. To facilitate integration of the calculation method into the commercial building simulation program TRNSYS 15, a new Type (Type 111) was written. This Type 111 can be used to connect an arbitrary facade construction to the existed building model Type56. Comparisons between calculated results from the developed model and measurements on real facades(a hybrid, mechanically-ventilated PV fagade and a naturally-ventilated, double glazed facade) provided sufficiently good agreement. The total energy rate through a window (g-value), estimated by the special g-value test rig at the Stuttgart University of Applied Sciences could also be reproduced accurately using the developed program.

Abstract:
This thesis discusses aspects of a novel solar concentrating photovoltaic / thermal (PV/T) collector that has been designed to produce both electricity and hot water. The motivation for the development of the Combined Heat and Power Solar (CHAPS) collector is twofold: in the short term, to produce photovoltaic power and solar hot water at a cost which is competitive with other renewable energy technologies, and in the longer term, at a cost which is lower than possible with current technologies. To the author’s knowledge, the CHAPS collector is the first PV/T system using a reflective linear concentrator with a concentration ratio in the range 20-40x. The work contained in this thesis is a thorough study of all facets of the CHAPS collector, through a combination of theoretical and experimental investigation. A theoretical discussion of the concept of ‘energy value’ is presented, with the aim of developing methodologies that could be used in optimisation studies to compare the value of electrical and thermal energy. Three approaches are discussed; thermodynamic methods, using second law concepts of energy usefulness; economic valuation of the hot water and electricity through levelised energy costs; and environmental valuation, based on the greenhouse gas emissions associated with the generation of hot water and electricity. It is proposed that the value of electrical energy and thermal energy is best compared using a simple ratio. Experimental measurement of the thermal and electrical efficiency of a CHAPS receiver was carried out for a range of operating temperatures and fluid flow rates. The effectiveness of internal fins incorporated to augment heat transfer was examined. The glass surface temperature was measured using an infrared camera, to assist in the calculation of thermal losses, and to help determine the extent of radiation absorbed in the cover materials. FEA analysis, using the software package Strand7, examines the conductive heat transfer within the receiver body to obtain a temperature profile under operating conditions. Electrical efficiency is not only affected by temperature, but by non-uniformities in the radiation flux profile. Highly non-uniform illumination across the cells was found to reduce the efficiency by about 10% relative. The radiation flux profile longitudinal to the receivers was measured by a custom-built flux scanning device. The results show significant fluctuations in the flux profile and, at worst, the minimum flux intensity is as much as 27% lower than the median. A single cell with low flux intensity limits the current and performance of all cells in series, causing a significant drop in overall output. Therefore, a detailed understanding of the causes of flux non-uniformities is essential for the design of a single-axis tracking PV trough concentrator. Simulation of the flux profile was carried out using the ray tracing software Opticad, and good agreement was achieved between the simulated and measured results. The ray tracing allows the effect of the receiver supports, the gap between mirrors and the mirror shape imperfections to be examined individually. A detailed analytical model simulating the CHAPS collector was developed in the TRNSYS simulation environment. The accuracy of the new component was tested against measured data, with acceptable results. A system model was created to demonstrate how sub components of the collector, such as the insulation thickness and the conductivity of the tape bonding the cells to the receiver, can be examined as part of a long term simulation.

Abstract:
Low concentrator PV-T hybrid systems produce both electricity and thermal energy; this fact increases the overall efficiency of the system and reduces the cost of solar electricity. These systems use concentrators which are optical devices that concentrate sunlight on to solar cells and reduce expensive solar cell area. This thesis work deals with the thermal evaluation of a PV-T collector from Solarus.Firstly the thermal efficiency of the low concentrator collector was characterized for the thermal-collector without PV cells on the absorber. Only two types of paint were on the absorber, one for each trough of the collector. Both paints are black one is glossy and the other is dull,. The thermal efficiency at no temperature difference between collector and ambient for these two types of paint was 0.65 and 0.64 respectively; the U-value was 8.4 W/m2°C for the trough with the glossy type of paint and 8.6 W/m2°C for the trough with dull type of paint. The annual thermal output of these two paints was calculated for two different geographic locations, Casablanca, Morocco and Älvkarleby, Sweden.Secondly the thermal efficiency was defined for the PV-T collector with PV cells on the absorber. The PV cells cover 85% of the absorber, without any paint on the rest of the absorber area. We also tested how the electrical power output influences the thermal power output of the PV-T collector. The thermal and total performances for the PV-T collector were only characterized with reflector sides, because of the lack of time we could not characterize them with transparent sides also.

Abstract:
Today the majority of UK's energy needs are met by fossil fuels. An energy sector that uses 30% of this energy and generates 28% of the total emissions is domestic sector. To reduce the emissions generated by fossil fuels UK government decided to increase the energy coming from renewable sources by 2020. A renewable energy that can contribute is solar energy. Solar thermal collectors and photovoltaics are two means of transforming solar energy to thermal and electrical energy. The limited space in the roofs and the cost of the technologies will prevent families to use both systems together in their roof A hybrid energy system combine the use of two or more alternative power sources will help to increase the system's total efficiency. The photovoltaic/thermal (PV/T) system is a hybrid structure that converts part of the sun's radiation to electricity and part to thermal energy. This research work focuses on the production of new approaches on hybrid PV/T systems. PV/T systems using water and air have been introduced and a literature review conducted in order to identify positives and negatives of these systems. Experiments also conducted by using water and air as heat transfer medium, and the results helped to work as a benchmark performance to the new approaches. These technologies were heat pipes, phase change materials and micro encapsulated phase change materials. The technologies exist for years but their use in the specific application is new. A literature review was undertaken to provide an understanding of these technologies and identified findings that have contributed to the design of the systems. Experimental work was carried out incorporating these technologies in the rear of a PV and the results indicated comparable performance with PV/T-water and PV/Tair. Five performance indicators were employed to help with the comparison of the systems. These were electrical and thermal efficiency, the total energy efficiency, the primary energy saving efficiency and the exergy efficiency. From these five indicators the primary energy saving efficiency that shows how much fossil fuel is saved and the exergy efficiency that could give the optimum working conditions of each system was the most valuable ratings. For the PV/PCM model a new simulation program was developed to help validate the experimental work. Also an environmental and economic study was undertaken to compare if the new systems could help reduce the C02 emissions and if they were feasible to become commercial products. Finally the conclusions gained have been presented and recommendations fo r future work have been made.

Abstract:

Due to the increasing energy costs and concern on carbon footprint, renewable energy technologies have become more important. Especially after the COP21 Paris meeting, increase in implementation of renewable energy systems has been an important agenda item of countries globally. Among these renewable technologies, solar energy is one of the key players. Hence research on photovoltaic (PV) panels has become more important.

This study investigates the heat transfer effect of water droplets on the panel surface. As surface temperature variation plays a significant role in the efficiency of the solar panel, understanding the heat transfer phenomena between the droplet and the panel is crucial. Temperature variation around the droplet-panel interface was studied both theoretically and numerically. Different cases were studied considering droplet volume, number of droplets, and the distance between the droplets. This research concludes that droplet retention on PV panel surface after a rain, condensation or irrigation event is observed when the drag force dominates the body forces. Amount of heat transfer increases with increasing droplet volume and contact area. Hence more heat transfer is observed over hydrophilic surfaces then hydrophobic surfaces. As the number of droplets over the PV panel surface increase, cell temperature decreases which would yield panel efficiency. It was observed that as the distance between the droplets increases, cooling effect lessens. This decrease in the cooling effect would get higher as the droplets get further away from each other.

Abstract:
Issues from global warming with increased CO2 emissions have been to a main concern over world. As an example in the UK, the energy demand in the domestic sector has risen by 17% in 2010 compared with that of 1970. Applying renewable energy is widely agreed to be the most effective and promising way to solve the problem where solar energy and photovoltaic technology have been greatly developing from the last century. Photovoltaic combines with Phase Change Material (PV/PCM) system is a hybrid solar system which uses phase change material to reduce the PV temperature and to store energy for other applications. This thesis aims to investigate the performance of a designed building integrated photovoltaic thermal system (BIPVT) with PCM as thermal storage for building applications. The research objectives are to increase the building integrated photovoltaic (BIPV) efficiency by incorporating PCM while utilising the stored heat in PCM for controlling indoor conditions and reduce the total building energy consumption. The research starts with solar energy convection technologies including solar thermal and solar photovoltaic. Then a combined technology named photovoltaic thermal system (PVT) was introduced and discussed. Research work on a different type of PVT using water and air as thermal energy medium was further reviewed and discussed. An analytical approach investigation was presented on a PVT system and the results were used to design the experiment work on PV/PCM configuration. Experiments have been carried out on a prototype PV/PCM air system using monocrystalline photovoltaic modules. Transient simulations of the system performance have also been performed using a commercial computational fluid dynamics (CFD) package based on the finite volume method. The results from simulation were validated by comparing with experimental results. The results indicated that PCM is effective in limiting temperature rise in PV device and the heat from PCM can enhance night ventilation and decrease the building energy consumption to achieve indoor thermal comfort for certain periods of time. An entire building energy simulation with designed PV/PCM air system was also carried out under real weather condition of Nottingham, UK and Shanghai, China. The result also shows a market potential of PV/PCM system and a payback time of 11 years in the UK condition if using electrical heater.

Abstract:
In an effort to reduce the cost of conventional fin and tube photovoltaic thermal (PV/T) collectors a novel mathematical analysis was developed which determines the optimum absorber plate configuration having the least material content and thus cost, whilst maintaining high collection efficiency. The analysis was based on the "low-flow" concept whose advantages include: improved system performance, smaller pump (less expensive with lower power consumption), smaller diameter tubes requiring lower thickness and thus cost of insulation, less construction power and time for the optimum absorber configuration. In this novel thermoeconomic optimization, the mechanisms of heat transfer from the fin to the tubes of the absorber plate and expressions of absorber plate material content and thus cost were identified and developed to allow for the absorber plate parameters (tube spacing, tube diameter and fin thickness) of the fin and tube PV IT collector to be optimized. In order for the useful collected heat (or thermal efficiency) of the PV/T collector to be held constant, the optimization procedure was based on holding constant the value of the PV IT collector efficiency factor.

Abstract:
Solar and wind power have low power densities. Large areas will be required to generate the electrical energy that we are using right now. These energy sources are intermittent, although sunshine is reasonably predictable in desert climates. Even in these ideal locations, fixed rooftop PV can only be used to meet a relatively small proportion of total electrical demand. Solar thermal with molten salt storage has a higher efficiency, and can better match electrical demands in these places. For wind turbines to generate their advertised or rated power, winds have to be blowing at about 12 m/sec (20 kt or 24 mph). In the United States, except in mountain passes and the Texas panhandle, this does not appear to happen very often. A simple test of whether a given renewable energy source is practical is to check whether it can meet the electrical demands of a single house.

Abstract:
A computational model of a PV module was implemented to describe its thermal behaviour considering the geographical conditions of the Yucatan Peninsula, Mexico. In order to analyze the effects of non uniform illumination on the thermal profiles of a PV module, a reflecting surface was added adjacent to a PV module edge. A finite difference formulation was used to represents the thermal patterns of each PV describing the thermal conditions of each particular solar cell within the PV module. The mathematical model and the preliminary results obtained for two time instants are presented using real meteorological data to reflect the effect of the wind patterns.

Abstract:
With recently increasing focus on solar energy, there has been increased interest in hybrid PV/thermal (PV/T) solar energy systems. In the PV/T system, a thermal energy recovery system is implemented to remove waste heat from the PV cells, thereby decreasing their operating temperature, leading to enhanced overall energy performance of the PV cells. The possibility of the utilization of waste heat recovered for hot water or space heating makes the PV/T system highly attractive for building integration. The main objective of this study is to conduct a state-of-the-art review and compare existing PV/T systems in terms of the factors limiting their electrical and thermal performance. Critical design parameters for maximum efficiency of PVT systems are identified and practical recommendations for improved design of PVT systems are provided.
