RO vs Demi water

Recommended Posts


Hi guys,


New here, so expect some dumb questions ;)


I posted this in here as I am currently looking into the possibility of offering my clients a cleaning service for their PV-systems.


I would be interested in your experiances concerning the cleaning properties between RO and Demi water?

Is there a real difference between them, so does on or the other remove dirt more easily?

I would also like to know if there is a difference between the "recontamination" of the glass surface between the two?


Sorry for my non native tongue, I hope everything is clear,

Hi sander, manufacturers recommend using purified water. Anything else will risk invalidating the warranty.
