Buying Guide
Choosing the right solar panel cleaning brush depends on several factors. Consider the size of your solar array, the type of dirt and grime you typically deal with, and your budget. Here are some tips to help you make the right choice:
- Bristle Type: Soft bristles are crucial to avoid scratching the surface of your solar panels. Microfiber is an excellent option for gentle cleaning.
