  • Thermal performance of V-trough solar air heater with the thermal storage
           for drying applications
    • Authors: M. Eswaramoorthy
      Pages: 245 - 250
      Abstract: It was analysed the thermal performance of V-trough solar air heater with the thermal storage for drying applications. An active V trough solar air heater having concentration ratio of 1.5 with the thermal energy storage is designed and fabricated by using the flat plate non-selective surface embedded by paraffin wax based thermal energy storage. The developed system is tested by thermal performance test at site having the latitude of 12.97° N and longitude of 77.57° E over the period of time with and without the thermal storage. It was found that the incorporation of thermal storage is gives 10% higher thermal performance than without the thermal storage and other existing flat plate air heater. The total cost of the system is INR.30834/- and it saves conventional fuels and saves environment. It was concluded that the proposed system will be more economical if it was hybridized with utilization of the renewable energy sources of heat or waste heat.

      Pages: 256 - 258
      Abstract: This paper presents the results of studies on the development of the technology for powdering agricultural products using solar energy. It is found that the evaporation of moisture from crushed products (pasty mass) is similar to the evaporation from the free water surface. It is much more intensive than the evaporation from noncrushed products and usually consists of one stage.

      Abstract: In the current paper presented short review of the state of the art of solar powered reverse osmosis (RO) desalination systems, basic parameters, energy demand of RO process and also exergy analysis. In order to identify the main energy losses in desalination processes, to improve their performances from a thermodynamic point of view, there is a need for exergy analysis. The exergy analysis or second law analysis involves a comparison of exergy input and exergy destruction along various desalination processes. Using the exergy analysis methodology, presented in the current paper, the specific exergy and exergy flow rates at various points of a RO system can be evaluated. Once exergy flow rates are available, exergy destroyed within any component can be determined from exergy balance.

  • Estimation of bright roof areas for large scale solar PV applications to
           meet the power demand of megacity Hyderabad
    • Authors: Sainu Franco; Venkata Ravibabu Mandla; K. Ram Mohan Rao
      Pages: 284 - 289
      Abstract: Hyderabad is reeling under a severe power crisis aggravated due to the recent bifurcation of the state of Andhra Pradesh. Telangana state needs more power than residual Andhra Pradesh due to greater demand from its Industrial and Agricultural consumers. The installed capacity (established as well as under construction) of power plants under Telangana Power Generation Corporation (TSGENCO) includes 2282.5 MW of thermal coal based power, 2081.76 MW of hydro power and 1 MW solar power. As more than 50% of the power source is coal based, there exists a threat of fossil fuel depletion and enhanced Green House Gas (GHG) emissions. Solar electricity has the potential to offset these negative impacts. This paper concentrates on evaluating the roof top area required for solar power generation using Remote Sensing and GIS apart from developing an algorithm using analytical methods, to estimate the photo-voltaic system components required, for the total power requirement of Hyderabad city.

  • Study of thermal characteristics of a heating module with parabolic trough
           concentrator and linear wedge-like photoelectric receiver
    • Authors: V. A. Maiorov; S. N. Trushevskii
      Pages: 290 - 294
      Abstract: New solar modules intended for typical solar collectors containing semiparabolic trough concentrators and receivers that convert solar energy into thermal energy are considered. Mathematical modeling is carried out to develop an algorithm for estimating the structure of a heating module with the assigned energy parameters according to the laws of geometrical optics, as well as heat and mass transfer. When using such modules, which are based on a parabolic concentrator and a receiver with a system of coolant flow, cogeneration plants can be designed to produce electricity and heat. The mockups developed using this procedure are studied on the corresponding facilities and are tested under in-situ conditions. A solar module with an asymmetric parabolic trough concentrator and a linear wedge-like photoelectric receiver of concentrated radiation with a system of coolant flow provides the maximum power of 386 W at a temperature of 40°C and an efficiency of 60%, and 319 W at 60°C and 49%, respectively. Such modules are proposed for use to design solar collectors with the required performance.

    • Authors: Rajesh Arora; S. C. Kaushik; Raj Kumar
      Pages: 295 - 304
      Abstract: The proposed work investigates optimal values of various decision variables that simultaneously optimize power output, net-work output and second law efficiency of solar driven Stirling heat engine with regenerative heat losses, conducting thermal bridging losses using evolutionary algorithm based on NSGA-II in Matlab simulink environment. Effects of design parameters as absorber temperature, concentrating ratio, radiative and convective heat transfers are included in the analysis. Pareto frontier is obtained for triple and dual objectives and the best optimal value is selected through four different decision making techniques viz. Fuzzy, Shannon entropy, LINMAP and TOPSIS. Triple objective evolutionary approach applied to the proposed model gives power output, net-work output and second law efficiency as (38.87 kW, 1.24 kJ, 0.3156) which are 18.19, 16.78 and 31.51% lower in comparison with reversible system. With the objective of error investigation, the average and maximum error of the obtained results are figured at last.

  • Synthesis of TiO 2 nanoparticle using sol–gel route and testing its
           photovoltaic performance in dye-sensitized solar cell
    • Authors: Shalin; Shailendra Kumar Shukla
      Pages: 309 - 314
      Abstract: In the present work, sol–gel method is used to synthesize TiO2 nanoparticle. The characterization of the prepared TiO2 powder is done using Powder X-ray diffraction (powder XRD), Scanning Electron Microscope (SEM), Energy-Dispersive X-Ray Spectroscopy (EDS) and Ultraviolet-Visible Spectrophotometry (UV-Vis). The XRD pattern reveals formation of anatase phase TiO2. The SEM images reveal agglomeration of nanoparticles. The absorbance spectrum of TiO2 nanoparticles was observed with excitonic peaks at 327 nm and the band gap came out to be ~3.2 eV. This prepared TiO2 was tested for photovoltaic performance by using it in the Dye sensitized solar cell (FTO/TiO2/N719/KI-I2/Pt). Conversion of solar light energy to electricity was successfully done using this TiO2. The fabricated cell showed an open-circuit voltage (V OC) of 587 mV and short-circuit current density (J SC) of 5.06 mA/cm2. Maximum power (P max) generated was 1.912 mW/cm2 with a fill factor (FF) of 0.644 and a conversion efficiency of 1.91%.

      Pages: 315 - 320
      Abstract: The effect of blade number on performance of drag type vertical axis wind turbine (VAWT) is studied by Ansys numerical simulation, it involves 3-blade, 5-blade and 6-blade VAWTs. The optimized width of blade for each VAWT at maximum power efficiency is obtained, and simulation for the wind turbine with different number of blade is conducted for the VAWTs with turbine radius of 2 m at the inlet wind speed 8 m/s. By simulations, it gets the evolution curve of torque with respect to time, and the cyclical characteristics for these wind turbines. The results show that the maximum power efficiency and the stability of the wind turbine increase with the number of blade of the wind turbine, however the optimal d/D decreases with the number of blade of the wind turbine. The maximum power efficiencies are 20.44, 24.30 and 26.82% for 3-blade, 5-blade and 6-blade wind turbines, and the correspondingly optimal d/D are 0.66, 0.40 and 0.35, respectively. While the optimal rotational rate of turbine decreases with blade number.

    • Authors: Emad Maher Natsheh
      Pages: 193 - 196
      Abstract: In Palestine, the electric power generated is not enough to meet the power demand of domestic and industrial sectors. In this article, a PV system of 220 kW peak was proposed as a renewable resource of power generation for grid connected applications in residential quarter in north Palestine. The proposed system was simulated using MATLAB solver, in which the input parameters for the solver were the meteorological data for the selected location and the size of PV panels. Results showed that it is possible for Palestine to use the solar energy to generate enough power for some villages or rural area. It is also possible to use such a system as a black start source of power during total shutdown time. Results also indicated that solar PV systems can be more economical than grid electricity.

  • Defects localization research in photovoltaic cells: Methods and devices
    • Authors: L. D. Saginov
      Pages: 201 - 204
      Abstract: The article presents a method to determine local defects in solar photovoltaic cells (PVC). It is based on the non-contact measurement of PVC area temperature distribution by a special thermovision system when applying forward and reverse voltage to the cell. Distribution of PVC surface temperature is determined by nonuniformity of current density (because of local defects) and reveals itself in the intensity of thermal radiation in the infrared spectrum (IR). The difference between the light detector signals when applying a forward or reverse voltage to PV cells and in the absence of applied voltage to the PVC is used to eliminate the effect of IR light patch, surface irregularities emissivity of solar cells, heterogeneity sensitivity light detector array. The hardware and software implementation techniques using the focal plane array of infrared 3–5 micron spectral range and 320 × 256 elements size are presented.

  • Experimental study and analysis on novel thermo-electric cooler driven by
           solar photovoltaic system
    • Authors: Ranjana Hans; S. C. Kaushik; S. Manikandan
      Pages: 205 - 210
      Abstract: Experimental study and analysis on thermoelectric cooler driven by solar photovoltaic system has been carried out. Here the research attention is on testing of system performance under solar insolation. Experimental results revealed that unit could maintain the temperature in the cooler at 10–15°C and have a coefficient of performance (COP) of about 0.34. Analysis of thermoelectric cooling system has been conducted on the basis of COP, cooling capacity and environmental issues. Further investigations verified that the performance of the system is a function of solar insolation rate and temperature difference of hot and cold sides of thermoelectric module etc. There subsist most favorable solar insolation rate which allows COP and cooling production to be maximum value respectively. It is anticipated that the cooler would have prospective for cold storage of vaccine, food and drink in remote and rural areas or outdoor conditions where electricity is not available.

      Pages: 220 - 225
      Abstract: This article presents the results of scientific–technical and engineering works on modernizing a big solar furnace (BSF) developed by the Institute of Materials Science, Academy of Sciences of the Republic of Uzbekistan, including works concerning the development of an automated control system for heliostats and the development of microprocessor local control systems for each individual heliostat that are managed by a mainframe computer with the relevant software, highly-precise sensors of the rotation angles of heliostat axes, and digital sun-tracking sensors. The system under consideration provides for a two-way command and data exchange between all local systems and the mainframe computer. This exchange will make it possible to perform the software control of the operation of each individual heliostat, including sun tracking based on a solar sensor, tracking based on mirror turning, and direct positioning, as well as to continuously monitor the heliostat field state, perform self-diagnostics, and maintain an automated heliostat field operation log. This article also describes works on modernizing mechanisms for heliostat rotation and motion control: the replacement of brush-type dc motors by more reliable asynchronous motors with inverters, installation of angular sensors, and reconstruction of rotation mechanisms.
