This chapter presents the proposed model of combination between Photovoltaic solar system resources and sound biometric techniques, to generate power energy from the sunlight using the PVS controlled by a sound biometric technique. This work contributes to research knowledge by proposing and validating a sound biometric technique for allowing to reduce the consumption of the generated power ene...

abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

in recent decades, due to increasing prices of fossil fuels and environmental pollution resulting from the increased energy demand, researches on renewable energy sources have attracted lots of researcher’s attention. limited investing sources and environmental issues are important factors effecting electricity generation sector. minimizing costs and environmental damages are issues being consi...

Solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23. A statistical analysis was performed to obtain their relationship with sudden storm commencement (SSCs) and Forbush decrease events (Fd) of cosmic ray intensity. An 11-year cyclic variation ...

Solar energy is the most abundant and clean on earth, developing equipment or devices with high-efficiency solar conversion an effective way to alleviate crisis. The majority of redox enzymes require a coenzyme provide hydrogen source needed for reaction process, commonly used nicotinamide adenine dinucleotide (NADH). However, NADH expensive easily decomposed, which greatly limits its applicati...

Advantages of wind-solar complementary power generation system to utilize solar and wind energy in the aspect resource technical economy have been reviewed tersely. Convenience entering exiting generating equipment load from DC as well AC bus are interpreted briefly. The factors that affect electrical output were analyzed studied. Based on law conservation, energetic matching algorithm was prop...

pastures play an important role in protecting environment and ecosystems. unfortunately more than 40 percent of pasturess in the world have been destroyed and 20 percent of destroyed pastures are located in developing countries. application of solar energy could significantly contribute to preserving the pastures. the main purpose of this study was to examine the role of solar energy in protect...

Various antireflection thin films are often used to cover glass to increase solar cell electrical parameters. In the recent years many efforts have been done to develop and improve of solar cell films with high electrical output. One of the most important challenges of obtaining of high-efficiency thin films of solar cells is creation an effective light trapping system. The new polymeric protec...
