The analysis of collected wind data at two sites in Gaza Strip namely, Gaza city and Gaza International Air Port in Rafah city is presented. The two sites are candidates for remote area wind energy applications The purpose of this paper is to present the results of the assessment of wind energy potential in Gaza Strip in order to evaluate the wind regimes for installing wind energy conversion systems for power generation. The data on wind speed, direction and frequency distribution are used to analyze wind energy characteristics and availability at some stations in Gaza Strip. The vertical extrapolation was based on the power-law expression, and the wind energy and potential have been estimated at the wind generator hub height of approximately 50 m. Also, values of Weibull parameters c and k are determined from wind summary statistics. Consequently, the wind power is estimated adopting the Weibull distribution expression. From the results of this paper, sites are recommended for the wind energy exploitation in Gaza Strip.

Furthermore, the values of the Weibull parameters c and k are determined from summary statistics of wind resource. Consequently, the wind power is estimated by adoption of the Weibull distribution expression. Based on the results of this paper, sites are recommended for wind energy exploitation in the Gaza Strip.

A B S T R A C TThis paper presents the design of a parabolic-trough solar collector system for seawater desalination in Gaza, collector-aperture and rim-angle optimization together with the receiver-diameter selection are presented. A comparison of concentrating collectors against conventional flat-plate collectors is presented. It is shown that for large-scale water production the parabolic-trough collectors are more efficient than the flat plate ones. The analysis considers visible radiation transfer, IR radiation exchange, conductive and convective losses, and energy transfer to a fluid flowing through the collector tube. The collector may have a tilted north-south axis, an east-west axis or it may fully track the sun and geometric parameters associated with tracking the sun are considered.
