Performance improvement of PVT module with applications of nano-fluids and phase change materials: A review

01 Feb 2020-
Abstract: Performance improvement of the PVT module is a very important topic in recent decades. Solar energy is a vital resource for mankind. Continuous elevation of the cell temperature of the PVT module results in a decrease in PV electrical efficiency. This review paper discusses the different techniques to cool the solar cell in order to reduce its cell temperature increasing its electrical efficiency and, also use the collected vital thermal energy to heat water (increase thermal efficiency) in a heat exchanger. A brief study on PVT/PCM and PVT/Nano-fluid system is done in this review paper. Furthermore, the PVT system is observed to be a very effective way to extract most of the available solar energy. Therefore, work must be carried out to increase their efficiency with the application of nano-fluids and phase change materials along with fins, or the use of binary nano-fluids/ nano- PCM to reduce the cost. This review paper highlights the application of PCM and nano-fluids for the effective cooling of the PV panel. more

Abstract: This chapter includes environment feasibility of solar hybrid systems. In this regard, drying system with PVT air collector has been studied in details. It is seen that the market has different types of PV modules (a-Si, CdTe p-Si, c-Si, and CIGS) are available in the market. Further, thermal modeling has been explored to calculate the thermal energy (TE). Weather-related data has been taken from IMD, Pune, for yearly analysis. Various temperatures, namely outlet air from collector, cell, drying chamber, and crop surface have been calculated through thermal modeling developed for the system. Further, energy payback time (EPBT) for 100% PV area with different PV technologies used on flat plate air collector-integrated drying system found between 3.2 and 1.59 years. Environmental feasibility has also been evaluated for various solar PV cell technologies integrated with the system. more

Abstract: The photovoltaic thermal solar collector, sometimes known as the hybrid solar collector generates both thermal and electrical energies simultaneously. A double pass photovoltaic thermal solar collector suitable for solar drying applications has been developed and tested. A steady state closed form solution to determine the outlet and mean photovoltaic panel temperature has been obtained for the differential equations of the upper and lower channels of the collector. Hence, the photovoltaic, thermal and combined photovoltaic thermal efficiencies can be obtained. An experimental setup has been developed. For given sets of operating and design conditions the theoretical and experimental outlet and mean photovoltaic panel temperatures can be obtained. Comparisons are made between the experimental and theoretical results and close agreement between these two values are obtained. more

Abstract: Nanofluids are embryonic fluids that exhibit thermal properties superior than that of the conventional fluid. The application of nanofluids is to achieve the highest possible thermal properties at the smallest possible concentrations, by homogeneous dispersion and stable suspension of nanoparticles in the host fluids. Nanofluids plays vital role in various thermal applications such as automotive industries, heat exchangers, solar power generation etc. Mostly heat transfer augmentation in solar collectors is one of the key issues in energy saving, compact designs and different operational temperatures. In this paper, a comprehensive literature on thermophysical properties of nanofluids and the application of solar collector with nanofluids have been compiled and reviewed. Recent literatures indicate the conventional heat transfer using nanofluids and their specific applications in the solar collector. more

Abstract: A robust maximum power point tracker (MPPT) using sliding mode controller for the three-phase grid-connected photovoltaic system has been proposed in this paper. Contrary to the previous controller, the proposed system consists of MPPT controller and current controller for tight regulation of the current. The proposed MPPT controller generates current reference directly from the solar array power information and the current controller uses the integral sliding mode for the tight control of current. The proposed system can prevent the current overshoot and provide optimal design for the system components. The structure of the proposed system is simple, and it shows robust tracking property against modeling uncertainties and parameter variations. Mathematical modeling is developed and the experimental results verify the validity of the proposed controller. more
