Abstract Parabolic trough solar collector systems are the most advanced concentrating power technology for large-scale generation purposes. The current work reviews various selective coating materials and their characteristics different designs in power. Solar absorbing coatings collect radiation convert it to heat. To promote higher efficiency lower energy costs at temperatures requires, this ...

in this research a flat plate solar air collector was investigated under direct solar radiation consisted of a slatted glass cover, perforated absorber aluminum sheets (porosity 0.0177, 0.0314 and absorber thickness of 2.5 mm). the effect of porosity on absorber efficiency of collector was evaluated. six levels of air mass flow rates (0.0056 to 0.0385 kg m-2 s-1) were adopted.average solar ener...

The overall thermal performance of a Parabolic Trough Collector (PTC) depends on its optical performance, particularly the uniformity of the irradiance distribution and the resultant optical efficiency of the collector. Local Concentration Ratio (LCR), optical efficiency and average light concentration are three fundamental parameters of the optical performance of a PTC. These parameters are af...

Renewable energy is one of the cleaner generation strategies practiced all over world to reduce environmental impacts and waste based on current sustainability in economic practices. Solar kind renewable sources for different application. The thermal storage system solar least methods research, utilization application attaining higher responses quite possible. In this paper, heat attained by pa...

Parabolic-trough solar collector fields are large-scale systems, so the application of centralized optimization-based control methods to these systems is often not suitable for real-time control. As such, this paper formulates a novel coalitional approach as an appropriate alternative scheme. The key idea split overall field into smaller subsystems, each them governed by local controller. Then,...
