Avoiding Damage Over Time: Cleaning your panels helps to stop damage to their surface from scratchy bits or stuff that can eat away at them. This simple upkeep can make your panels last longer, cutting down the chances of cracks or other wear that might cost a lot to fix.

Geographic Location: The region where one lives can also determine how frequently solar panel cleaning should be done. If, for instance, one lives in a dry and dusty area, the solar panels will tend to get dirty more frequently, and thus regular cleaning would be needed. On the other hand, regions that have regular rains may do away with dust and dirt, and it may not be necessary to do cleaning often.

Environmental Factors: Properties located too close to highways, construction, and uptown or seaside will tend to have more pollution. Due to this hazards such as construction dust or salt water will also collect on the surfaces of the solar panels, leading to more clingy dirt on them.

Tree Cover: The positioning of the solar panels affects their cleaning and maintenance. If solar panels are installed close to trees, particularly those that shed leaves in autumn, cleaning is likely to be needed more often. Sun’s rays can be affected by dust, leaves, pollen, and bird droppings.

Seasonal Changes: In cold climates where humidity is high, such as rainstorms or where heavy pollen exists during the prolonged dry seasons as well as after extreme climatic conditions, cleaning and checking the condition of your panels would help preserve their effectiveness.
