Development of a low power robot prototype for cleaning of Linear Fresnel concentrator mirrors

Middle East and North Africa (MENA) region experiences very harsh weather condition mainly as it comes to dust and humidity. Structural errors, dust deposition, tracking errors are some of the parameters that needs to be analyzed to evaluate the sensitivity of the energy yield [1]. Dust and humidity are one of the environmental factors. The effect of these conditions can adversely affect the efficiency of the solar based system, most importantly the concentrated solar power system which relies on the reflection of the light on the line or point focal point. Hence soiling for the reflectors can hugely effect the overall viability of the technology in this region. This study aims to achieve it by carrying out a detailed study of effect of dust and its composition. Further the use of combination of methods available in the market to mitigate them. Finally conceive the design based on the initial tests and approaches to make the cleaning robot for the Linear Fresnel concentrated Mirror.
