Dirt and dust can reduce energy output of solar modules by up to 20%. iSolar is a new pressure washer accessory from Kärcher Professional designed for thorough cleaning of solar panels. It features two rotary brushes and a telescopic lance that can clean up to 16,145 square feet of panel economically, depending on the model, and it can be used with any Kärcher professional pressure washer with a flow rate of at least 4.85 gallons per minute.

iSolar comes in a single – small area coverage – and dual – large area coverage – disk brush configuration. Both brush configurations are made from non-scratch nylon bristles, providing safe and gentle cleaning of panels. Powered by water from the pressure washer, the brushes rotate in opposite directions, allowing iSolar to be guided in straight runs with little effort. When iSolar is connected to its adjustable telescopic lance, the operator can safely clean up to 45 feet. The lances are made of high-quality carbon and carbon composite that make them light and durable, and they have a ball valve control that allows the operator to easily switch on or off the water flow. All of iSolar’s connections are made of brass and stainless steel to prevent corrosion.

When water alone is not enough to clean solar panels, Kärcher’s RM 99, a low-alkali detergent, is perfectly adapted for cleaning their unique surface. It also does not corrode aluminum frames and dries without leaving streaks.

For over 75 years, Kärcher has been a world leader in cleaning technology. With over 2,000 products, Kärcher understands cleaning challenges and provides innovative solutions. Kärcher has more than 1,000 registered inventions and patents, with over 85% of its products developed in the last 5 years. Around the world, Kärcher is known for power, quality and innovation.
