Abstract: Solar- LED outdoor lighting system allows governments to illuminate remote areas without electric network. For these systems a battery is required to store energy from PV panel during the sunshine and supply the LED light during the night. This paper presents simple analytic procedure for optimal sizing of PV panel- LED light and battery combination considering radiation data. Real meteorological data are used in MATLAB to calculate system components capacity. After that, stand-alone and grid connected solar- LED system is presented in terms of optimum tilt angle and amount of surplus energy. Finally, the PV panel is oriented at optimum tilt angles for seasons and compared with energy which is obtained at annual optimum tilt angle

Abstract: In the present work, experimental investigation of the performance of double bed desiccant dehumidification system has been carried out. The two desiccant beds operate simultaneously. When one of the two beds functions as an adsorber, the second operates as a regenerator. In this investigation, silica gel is applied as the desiccant material. Hot air from an air heater is blown through the regenerated bed using an air blower. System performance at different conditions of flowing air is demonstrated. The experimental tests were carried out at different conditions of inlet air and initial bed parameters. Temperature and humidity of air at the inlet and exit of the bed were measured. The effect of adsorption to desorption air mass ratio is examined. In the present study, it is found that 63% regeneration to total air mass ratio is the optimum value.
