This paper presents the life cycle cost analysis of the single slope passive and hybrid photovoltaic (PV/T) active solar stills, based on the annual performance at 0.05 m water depth. Effects of various parameters, namely interest rate, life of the system and the maintenance cost have been taken into account. The comparative cost of distilled water produced from passive solar still (Rs. 0.70/kg...

A passive solar tracker and concentrator device must be able to effectively concentrate solar radiation into a constant area throughout the day, without any mobile mechanism. The objective is to achieve 1000 °C on the receptor area with concentrated solar energy, and to accomplish this target a compound Fresnel lens has been designed. Utilizing multidisciplinary CAE software, an integrated mult...

This study presents a new and innovative suggestion to design solar water desalination system by the direct passive method, with aim of raising productivity recycling energy lost during process efficiency condensation. In this study, was evaluated demonstrate its ability increase while maintaining simplicity installation ease operation. A prototype built make detailed on raise under several dif...

in this paper, optimal design of hybrid solar-wind- diesel energy system with battery storage for reliable load in arsoon village in ardabil is presented. the village has 35 households that mean daily energy consumption is estimated 63.4 kwh. in this design optimization is implemented, considering loss of power supply probability (lpsp) index for reliable load providing, with minimum total cons...

The presented paper is a techno-economic feasibility study to use solar energy as a renewable energy to power the Passive Optical Network (PON). This discussion focuses on the requirements and sources of power for the active components of optical access networks. To ensure continuous reduction of the carbon footprint while advancing towards purely passive optical networks, we have emphasized th...

since the energy consumption has become one of the crisis of modern buildings, modeling the iranian past architecture patterns could be helpful. the shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. however, using passive techniques, the iranian traditional bazaars architecture solved the problems regard...
