ENERGY INCREASING COATING
Durable repellent nanocoatings for PV modules which improve electrical productivity and protect surface from contamination
Dirt, dust, oil and water reduce solar power output by up to 40-50%
The productivity can be raised by applying self-cleaning long-lasting nanocoating. It's easy to apply and improve efficiency of solar panels by increasing energy output and saving costs for cleaning.
Our advantages
Improving the efficiency
Improves the sunligh transparency and raises the electrical productivity up to 5%

Selfcleaning effect
Protects from dirt, dust, oil and water
