Concentrated Solar Power (CSP) is a technology that capturesand exploits solar thermal energy by concentration. It uses highly pol-ished mirrors called heliostats to focus the sunlight onto a target. Inside the target, there is a transferring fluid that will be heated and then it transfers heat to heat exchangers to generate power. The possibility of installing a CSP plant at urban, rural or semi-urban locations makes it a desirable choice for electricity generation plants. Also, it has the possibility of installing in industrial areas as long as the array is not in a shaded area.
In the present study, the effect of desertic environmental conditions on CSP plant was evaluated by fabricating two heliostats fields. Some plant variables like target temperature, efficiency, and stored energy were measured and evaluated. The desert dust was the primarilyaffected factorthatits accumulation on heliostats causes high reduction of the studied variables. The average reductions measured were 24, 12, 15 and 4% for spring, sum-mer, autumn and winter seasons respectively. Spring season ranked the highest reduction due to the high dust storm reiteration during it. At winter sea-son, the rainfall limits the dust effect. The high solar intensity in Iraq, Baghdad city taken as case study, manifests the possibility of construct and oper-ates CSP plants with high efficiency in spite of the desertic environmental conditions. The study results clarified the importance of washing and cleaning the heliostats from dust several times per month to reduce dust effects.
