Condensation problem on the back of photovoltaic panels
Effect of condensation on PV panel performance. Another major setback under desert environment is the high possibility of moisture condensation on the surfaces of the PV modules. Due to radiation heat exchange between the PV surface and the cold nocturnal sky, the PV surface temperature drops to lower than the ambient dew point temperature.

However, dust agglomeration on the surface of photovoltaic panels causes damage and impedes their ability to efficiently turn sunlight into electricity. Because condensation is a driving force in dust aggregation, Hu et al. investigated the dust agglomeration process during condensation.
We try to identify the reasons for the difference of chemical components in different dusts, analyse the effect of organics on the adhesion of dust to the surface of PV panels under the condensation phenomenon, and investigate the adhesion mechanism of organics between dusts and the surface of PV panels.
This device uses the power from the solar panel and cleans the panel and night. This robot can clean the dust and bird droppings effectively. It can also withstand extreme heat, humidity and coldness. To reduce the impact of dust on solar panel surface, a robotic arm-based self-automated dust removal system was designed and developed using IR .
Soiling and condensation affect the performance of PV systems and greatly degrades their power output. Covering the PV panels during non-operation will greatly improve the overall efficiency and reduce the PV soiling. In the present study, a motorized curtain is developed to cover the PV module surface during nights and dust storms.
