Karcher iSolar 400 & 800

Solar Panel Brush Cleaner

Available for sale are the Karcher iSolar 400 & 800 Solar Panel Brush Cleaners. These brushes make cleaning your solar panels easier than ever!

iSolar 400: Single disc 400mm / 16" cleaning path.
iSolar 800: Dual disc 800mm / 32" cleaning path.

The Karcher iSolar utilizes the power of your pressure washer in order to operate the disc heads. The flexible angle joint allows for comfortable handling while ensuring the bristles always lay flat and pressure is evenly applied to the surface of your panels. The soft nylon brushes operate at low pressure to safely clean the delicate surface of your solar panels and maximize your power generating capabilities.

Cold or hot water pressure washers can be used. Up to 104 degrees F of hot water at brush head is acceptable, and Karcher offers a special solar panel detergent than can be added to your water tank for extra cleaning power (hot water models only).

Various telescopic wands and pressure hose combinations are available, and Caliber can help you determine the combination of which will be appropriate for your application.

A compatible pressure washer is required for operation of the iSolar panel brush cleaner!
