<br/><br/> The new cleaning mechanism using dew was tested indoor with different types of wipers, different cleaning angles and with different surface wetting time. The cleaning efficiency with this mechanism was very high, it reached 99.3% for normal single wiper, 98.9% for industrial wiper and 98.3% for normal car wiper. This mechanism can save big quantities of water consequently lead to reduction in operation and maintenance cost. But it must be considered that the system depends on dew potential of the CSP plant area which is exemplarily investigated for one solar site
