  • Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions

    Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...

  • Studies on performance characteristics of a solar parabolic trough concentrator with a variable area absorber

    The design of a suitable absorber that incorporates an efficient heat transfer augmentation technique is one of the vital parameters that affect the performance of a solar parabolic trough concentrator (PTC). The variable area absorber discussed in this paper provides appreciable augmentation in heat transfer without increasing the pressure drop materially and thus helps in enhancing the ...

  • Removal of humic substances using solar irradiation followed by granular activated carbon adsorption

    This study proposed a new method using freely available sunlight and granular activated carbon (GAC) adsorption for enhanced removal of humic substances (HS). Experiments were carried out under natural sunlight conditions in winter and summer. A parabolic solar collector (PC) was applied to concentrate solar energy. HS were characterized by UV254 absorbance, dissolved organic carbon (DOC) ...

  • Kuwait: A CSP market worth entering?

    Kuwait's renewable energy plans show that CSP has a paramount role to play in the country's future energy mix, but when will developments pick up pace? Progress in Kuwait's CSP projects has been slower than anticipated. While the net gas importer signed multi-year supply deals for liquefied natural gas with Qatargas and Shell, and is considering similar agreements with Iran and the United ...

  • Italy: the next CSP hotspot?

    Italy could potentially have a booming CSP market, thanks to high DNI levels in the southern parts of the country and in the main islands of Sardinia and Sicily – where one of the newest CSP plants, the 50 MW Mazara, is being built. Feed-in-tariffs (FiTs) for CSP generation and industrial needs for process heat should make the market even more attractive. So why aren't developers flocking ...
