Available in PDF, EPUB and Kindle. Book excerpt: As part of the Jet Propulsion Laboratory's Low-Cost Solar Array Project, test methods have been evaluated and procedures developed for testing photovoltaic flat-plate solar cell modules for resistance to impact by hailstones. Testing has included the use of simulated hailstones (frozen ice spheres projected at terminal velocity), steel balls, and other projectile types applied with three loading methods: pneumatic gun, gravity drop, and static loading. Results are presented that compare the advantages and disadvantages of the three test methods. Dropped-steel-ball tests are shown to exhibit little correlation with high-velocity ice-ball tests, whereas statically-loaded steel balls show a somewhat better correlation with ice-ball tests. Results are also presented on the hail impact strength of 16 flat-plate photovoltaic modules. The module designs tested have been shown to be capable of withstanding as large as 1-1/2-inch diameter and not capable of withstanding as small as 1/2-inch diameter simulated hail. The top surface material of the modules has a dominant influence on the hail impact resistance of the modules. In order of increasing impact strength for a given thickness, the top surface materials encountered in the modules tester were: clear silicone rubber, annealed glass, tempered glass, and acrylic sheet. The critical failure mechanism of each module type is explored and means for improving the hail resistance of future modules are described.

Book Effect of Hail Impact on Thermally Tempered Glass Substrates Used for Processing CdTe PV Modules

Download or read book Effect of Hail Impact on Thermally Tempered Glass Substrates Used for Processing CdTe PV Modules written by Tushar M. Shimpi and published by . This book was released on 2008 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IEEE 1262 standard provides qualification tests and specification to evaluate photovoltaic (PV) modules intended for power generation applications. The hail impact test is one of the tests. It is conducted to verify that the module will withstand a simulated hail impact without damage. The modules are tested with 1-in. diameter ice balls traveling at a velocity of 52 miles/h. Based on the results, the use of 3-mm tempered glass substrate for processing is recommended to withstand the hail impact test. The stresses developed by the samples during the hail impact test have been estimated.

Book Research on Solar Collector

Download or read book Research on Solar Collector written by Loreto Valenzuela and published by MDPI. This book was released on 2020-12-02 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of concentrated solar technologies has grown significantly worldwide in the last decade but the research and development of this renewable energy technology still needs to be advanced to guarantee its competitiveness with other energy sources. Challenges remain with reducing costs, optimizing the systems design, and increasing the performance and durability of the systems.This Special Issue on research on solar collectors presents some recent developments and studies on tracking-solar collectors for medium- to high-temperature applications, both line- and point-focus systems, conceived for the supply of heat in industrial processes, to provide thermal energy to a power block for electricity production, or even to combine heat and electricity generation in a solar collector unit (CPV/T). The articles included in this Special Issue cover theoretical or practical issues on geometrics optics, thermal–hydraulic modelling, and performance analysis, focusing on the following topics:• Solar towers: heliostat fields analysis and optimization• Solar towers: heat transfer media studies• Parabolic troughs: evacuated solar receivers analysis and thermal–hydraulic modelling• Fresnel reflectors: geometrics optics and manufacturing issues• Fresnel lens in CPV• Energy losses in solar collectors systems
