Get maximum return from your solar panels!


It's best to have your solar panels cleaned once a year, if you really want to get the maximum return from your installation,

even up to 4 times a year.


Bulens Cleaning always uses osmosis water for cleaning solar panels. This water is free from algae and lime, so there is no chance of limescale or greenery forming afterwards.


We use our telewash as much as possible so that we do not have to enter your roof or gutters.

Softwash is the use of biodegradable chemicals that remove dirt, dust and immediately cleans insect nests and cobwebs.
It also immediately kills all algae, bacteria, fungi, (lichen) moss and mildew.


The result is a disinfected and thoroughly cleaned surface.


Softwash only uses a third of the water compared to high pressure washing.


The result remains visible four to six times longer.


High-pressure cleaning is often the visual removal of the dirt. However, the cause of the dirt often remains deep in the pores.
High-pressure cleaning is also compared to shaving the pollution.

Our chemicals really do more than just clean;

they penetrate deep into the material, disinfect the surface and also remove the roots of the organism.

What is osmosis water?



Osmosis water is created by filtering pure water under high pressure through an ultra-fine membrane.

This removes all impurities such as ammonium, salts, nickel, chlorine, lime, zinc, manganese....
