Solar Panel Cleaner FAQs
Why do I need a solar panel cleaner?
Solar panels are exposed to various elements like dust, grime, bird droppings, and other debris, which can reduce their efficacy. Solar panel cleaners help clean these panels and maintain their productivity.
How often should I use a solar panel cleaner?
The frequency of cleaning depends on the environment in which your panels are installed. In general, it is recommended to clean them every 6 months. However, if your panels are in a very dusty area or under a lot of tree cover, you might need to clean them more frequently.
Can I use any kind of solar panel cleaner on my panels?
While there are many solar panel cleaners available, it's essential to choose one specifically formulated for solar panels to avoid damage and ensure optimal performance. Using cleaners not designed for solar panels may leave streaks and residues, or even cause damage to the panels.

Are there any safety considerations while cleaning solar panels?
When cleaning solar panels, it's essential to prioritize safety by turning off the system to avoid electrical hazards, especially if the panels are hot or wet.
