For businesses and homeowners alike, investing in these technologies ensures cleaner energy, lower costs, and a greener future.
Environmental factors vary significantly across different regions and directly impact how often solar panels need to be cleaned.
In dry and dusty areas, solar panels tend to accumulate dust quickly. It is generally recommended to clean the panels at least once a week to ensure that energy production is not significantly affected.
In more humid areas, dust and pollutants accumulate less, allowing for a reduced cleaning frequency. Cleaning once a month may be sufficient in these conditions.
After rain or snow, dust and debris on solar panels may mix with water, leading to dirt that can severely impact energy efficiency. Therefore, cleaning should be performed immediately following rainfall or snowmelt.
The cleaning frequency also depends on the installation location of the solar panels.
Rooftop solar panels, which are exposed to various environmental factors, should ideally be cleaned at least once a month to maintain optimal conditions.
In ground-mounted solar parks, the panels usually cover larger areas. If cleaning is done manually, it can be cost-prohibitive and inefficient. Therefore, using cleaning robots can facilitate more frequent cleaning. A frequency of at least once a week is recommended for ground-mounted solar installations to ensure maximum efficiency.

Best Time: Early morning or late night on clear days to maximize benefits of cool temperatures and visibility.
Best Time: Any time during the day, but early morning or late night remains preferable for consistency and comfort during cleaning.
Best Time: Avoid cleaning unless panels are severely contaminated and rain is insufficient for proper cleaning, as the surface can be slippery.
Best Time: Clean as soon as possible after a dust or sand event, ideally during the cooler hours of early morning or late night to mitigate efficiency loss.

The first inspection of the rail-type photovoltaic robot should be carried out immediately after installation to ensure all systems are operating normally. Subsequent routine inspection cycles can be adjusted according to specific situations and needs; however, the following is generally recommended:
