At Quality Flex, we clean your solar panels with demineralized water – for crystal-clear results. But what exactly is demineralized water, how is it produced, and why is it so effective? And most importantly: what can our demineralized water do for your solar park? Contact us today to learn more.
WHAT IS DEMINERALIZED WATER?
Demineralized water is fully purified water – free from minerals, salts, metals, and other impurities. Unlike tap water, it contains no lime, chlorine, iron, or other residues that can leave stains or streaks.
he name comes from the process of reverse osmosis: water is filtered so thoroughly that almost only H₂O remains – pure water in its cleanest form. This exceptional purity is what ensures perfect cleaning for your solar panels.
THE ADVANTAGES OF DEMINERALIZED WATER
- Streak-free cleaning – no minerals, lime, or residues
- Maximum light transmission – more sunlight, higher energy yield
- Environmentally friendly – no chemicals, just pure water
- Longer-lasting cleanliness – attracts new dirt less quickly
- Protects your investment – gentle cleaning extends the lifespan of your panels
With our robot-assisted cleaning and in-house demineralized water production, Quality Flex guarantees top performance for your system.
HOW WE PRODUCE OUR DEMINERALIZED WATER?
We use a mobile system that allows us to produce demineralized water directly on-site. This makes us independent of external suppliers and enables us to work flexibly anywhere.
Water source
Ground-mounted parks: We drill 10–20 meters deep, extract groundwater, and purify it immediately. The water returns to the ground without chemicals – eco-friendly and sustainable.
Rooftop installations: We use the existing tap water and purify it through our reverse osmosis process
Osmosis process
Our osmosis water production process consists of several steps:
- Pre-filtration – removal of sand, rust, chlorine, and coarse particles
- Reverse osmosis – under high pressure, water is pushed through special membranes that allow only water molecules to pass through. Several filtration stages ensure over 99% purity.
Which substances are removed?
The osmosis process is effective in removing virtually all contaminants:
- Minerals & salts: e.g. calcium, phosphorus, heavy metals
- Chemical residues: pesticides, medication traces, chlorine
- Biological contaminants: bacteria, viruses, algae, parasites
WHY WE PRODUCE OUR OWN DEMINERALIZED WATER
