For those who wash regularly, concentrate is the only sensible choice. You don't pay for water transportation and you don't take up storage space with bottles that are mostly water.
One liter yields one hundred liters of ready-made solution, which is enough for about 800 to 1,000 square meters of panels. This brings the price per square meter down to a few cents, which is a decisive figure when it comes to larger installations.
The formulation is neutral and mild towards the glass and frame, without strong alkalis and without abrasive particles. It is diluted with demineralized water, which is also the base of the concentrate itself, so after drying nothing remains on the panel.
The concentrate does not contain preservatives, as they are not needed with this concentration of active ingredients. Use the prepared solution on the same day.

Frequently asked questions
Why demineralized water?
Because the result is only visible after it dries. Salts from plain water remain on the glass as white spots, no matter how good the product is.
How long does the prepared solution last?
Use it the same day. Diluted product has no preservatives and will spoil over time.
Can it be used in machines and systems with brushes?
Yes, with the usual precautions. M8 Solar Foam is intended for systems with a foamer.
What is the price difference compared to the ready-made solution?
For regular washing, multiple times. Ready-made solution makes sense for one home installation, concentrate for everything else.
