Every wash costs money — time, water, going out on the roof or in the yard. The cheapest wash is the one you don't have to do.
M8 Solar Protect bonds a silane layer a few molecules thick to clean, dry glass. This layer is invisible and does not change the appearance or permeability of the glass, but it does change the way water behaves. Instead of spreading into a film that dries and leaves dust, the water collects in droplets and runs off, taking some of the deposits with it.
The result is a panel that gets dirty more slowly and is partly washed away by rain. This extends the time between two thorough washings, which is a saving that is reflected in the labor bill every time.
It is applied after washing, on a completely dry panel, and sets for 24 hours. It is not diluted. The effectiveness is easily checked — pour a little water and see if it collects in drops.

Frequently asked questions
Can it be applied to a dirty panel?
No. The coating only bonds to clean and dry glass. First wash with M8 Solar Clean and let dry completely.
How long does the protection last?
It depends on the location, slope and amount of precipitation. We recommend renewing after every thorough washing.
Does it change the appearance of the panel?
No. The layer is invisible and does not affect the appearance of the glass.
How to check if it worked?
After setting, pour some water. On the treated glass, the water collects in drops and runs off.
