英文要約High performance PV generation system for the future
Development of Reflection Concentrated Photovoltaic Generation System
We studied concentration performance of Trans Axial Reflector (TAR) and Beam Down Trans Axial Reflector (BDTAR) as concentrated photovoltaic generation system. The targets of concentration performance on this study are as follows;
-Geometric concentration ratio: x500 for TAR, x1000 for BDTAR
-Concentration efficiency: 70% for TAR, 50% for BDTAR
-Concentration ratio: 300suns for TAR, 430suns for BDTAR
1) Design and Manufacturing of Test machines for Laboratory and Field test
Laboratory and Field test machines were designed and manufactured. Laboratory test machine was installed at Nagaoka University of Technology, and Field test machine was installed at MES Tamano Works.
2) Experimental test and Numerical simulation of TAR Concentration
We studied TAR Concentration performance by both Experimental tests and Numerical simulations. The test results were obtained about the concentration efficiency and the profile of concentration area as a parameter of sun altitude 30, 45, 60, 75 and 90 degree. The numerical simulation results of both the concentration efficiency and the profile of concentration area were similar to the experimental at all of the sun altitude conditions. Therefore, the validity of the numerical simulation was verified by the experimental data.
3) Experimental test and Numerical simulation of BDTAR Concentration
We studied BDTAR Concentration performance in the same method as TAR tests. The numerical simulation results of both the concentration efficiency and the profile of concentration area were similar to the experimental at all of the sun altitude conditions. Therefore, the validity of the numerical simulation was verified by the experimental data.
4) Full-Scale module performance estimated by TAR/BDTAR Numerical Simulation Results
The full-scale module concentration performance was estimated by the numerical simulation results based on the conditions of real-sunlight irradiated, x510 (for TAR)/x1041 (for BDTAR) of geometric concentration ratio and the mirror data of commercial products. The concentration efficiency of TAR was 73% at 60 degree of sun altitude and BDTAR was 43% at 60 degree.
5) Development of New TAR
A new TAR type concentration method was developed to achieve x1500 geometric concentration ratio. Numerical simulation confirmed the achievement of more than 1000sun for this device. The additional CPC (Compound Parabolic Concentrator) installation enables the following results.
-Uniformity of concentration state on a panel
-Ease of reduced concentration efficiency due to sun altitude
-Ease of allowable sun-tracking tolerance
6) Solar cell radiation test
An air-cooled fin type heat sink was studied to keep the temperature of solar cell back panel under 100 degrees Celsius. Verification at TAR was done by applying the following methods and confirmed the validity of CFD method.
-Heat transfer calculation
-CFD calculation
-Experimental data obtained using simulated heat source
