Karcher iSolar. Making way for the power of the sun.

Photovoltaic and solar thermal energy modules harness solar radiation and convert it to energy. But debris from dust, soot and pollen can reduce their output by up to 20%, negating some of their efficiency. The natural power of rain, condensation and wind are nowhere near strong enough to clean the modules effectively. These systems require regular, thorough cleaning in order to produce a consistently high level of power.

iSolar – wherever the sun is shining.

Because dirt buildup leads to a loss of power that translates to lower electricity production, iSolar pays for itself in no time.

Wherever solar and photovoltaic systems are installed – agriculture, trade, industry or in the home – iSolar will ensure the sun’s energy is properly harnessed. There are practically no limitations on how iSolar can be used. This is particularly helpful in areas exposed to heavy soiling. Karcher iSolar represents an economical choice for both system operators and cleaning service providers.


Gentle but thorough: the iSolar 800/400

The iSolar 400 and iSolar 800 offers superior cleaning, thanks to brushes that are powered by the water jet from the pressure washer. Cleaning is achieved by the mechanical action of the bristles, made of nylon for scratch-free modular surface cleaning. The iSolar 800 is operated at low pressure, eliminating any danger of the modules being damaged. The rotating brushes are fitted with robust ball bearings to guarantee exceptionally long service life.


iSolar 400

The iSolar 400 water-driven disc brush features a working width of 15.75" and is especially suited to cleaning smaller to medium-sized photovoltaic systems. Thanks to the low weight and easy handling, elevated solar systems can be conveniently cleaned.
