One of the greatest challenges of renewable resources is unpredictable nature of these resources. Nevertheless use of fossil-renewable integrated hybrid system, which uses some renewable resources rather than a single source, for the supply of power, is the most affordable and the most reliable method. In this study by use of analytical programming approach and 2012 base year statistics, produc...
One of the methods for increasing the gain in the photovoltaic systems is using the solar tracker system which during the whole of day, align the solar panels in the proper position with respect to the sun position. In this study, a solar tracker in the form of smart light curtain was designed and prepared. This simple and smart tracker detects the direction of the sun radiation by using three ...
-This paper describes a novel data acquisition system designed and implemented with facilities for measuring and monitoring the characteristics of a PV solar cell , module and/or system. The functioning of the equipment is based on the so-called virtual instrumentation. This is a non-conventional concept, however it does not have the many limitations in other systems. Additionally, the whole eq...

Measured monthly atmospheric depositional fluxes of cosmogenically produced (7)Be ranged from 1 to 67 mBq/cm(2) in Boston, Massachusetts between September 2000 and August 2007. These fluxes exhibited seasonality and supported a decay-corrected (7)Be atmospheric depositional running inventory that ranged from 36 to 144 mBq/cm(2). Annual (7)Be deposition exhibited an increasing trend that may ref...
many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
As solar heating systems become a commercial reality, greater efforts are now being employed to incorporate solar cooling components in order to obtain a complete solar heating and cooling system, and thus take advantage of the cost-effectiveness of year-round use of the solar equipment. The solar heating and cooling system design presented in this paper incorporates design considerations which...
در این پژوهش به منظور برآورد تابش خالص برای مکان یابی نیروگاه های خورشیدی با پردازش تصاویر ماهواره ای در استان کردستان از دو روش sebal و روش solar analysis استفاده شده است در روش sebal از داده های تصاویر ماهواره ای مودیس 2000، 2003، 2006، 2009، 2012 داده های ساعات آفتابی در7 ایستگاه سینوپتیک در سطح استان کردستان ( داده های روزانه) و برای روش solar analysis از تصاویر دم منطقه با قدرت 30 و 90 متر...
