Servicing and cleaning
guide price from€139
Clean panels and a yearly check of the whole chain.
Bird droppings, moss and fine dust cost yield, especially on panels with a shallow pitch. We clean with osmosis water and a soft brush, without soap or high pressure. During a service we also check the hooks, cables, connectors and the inverter. A short report with photos follows by email.

What dirt costs you
The flatter your panels and the more trees, birds or dust nearby, the more yield you lose. On a steep tiled roof it's usually not too bad.

Two questions almost everyone asks
Why no soap or pressure washer?
Soap leaves a film that dirt sticks to again, and high pressure can damage a panel's seal. Osmosis water dries without limescale marks.
How much yield does dirt cost?
With panels on a shallow pitch or under trees, easily five to ten per cent. On a steep tiled roof usually less.
What can your roof do?
A roof scan costs nothing. Five working days later we email a layout and an honest calculation, even if the answer is that it doesn't pay off for you.
