One of the most common questions we receive at Ultimate Solar Care is: Hose Water vs Deionised Water for solar panel cleaning, what’s the difference and which is better?
In simple terms, Deionised (DI) water is water that’s been filtered to remove all ions and minerals, making it ultra-pure.
Let’s learn the difference and how DI water makes solar panel cleaning for a better outcome.
Hose Water – Can Reduce Efficiency & Damage the Panels
Using tap water or hose water might seem like a convenient option for cleaning your panels, especially for DIY jobs. However, regular water is full of minerals like calcium, magnesium, and other impurities.
Downsides of Using Hose Water:
- Leaves Spots & Streaks: As the water dries, it leaves behind mineral deposits that create white spots or film on your panels.
- Can Reduce Efficiency: These mineral spots can block sunlight from reaching the cells, reducing your system’s energy production.
- Potential for Damage: Over time, repeated use of hard water can lead to a build-up of residue that is harder to remove and could potentially damage panel coatings.
Deionised Water – The Gold Standard in Solar Panel Cleaning
Deionised (DI) water is water that’s been filtered to remove all ions and minerals, making it ultra-pure.
At Ultimate Solar Care, we use deionised water with specialised cleaning equipment to ensure a spotless, safe clean every time.
Benefits of Deionised Water:
Streak-Free Finish: Leaves no residue, marks, or film, just clean, high-performing panels.
- Improved Efficiency: Clean panels allow maximum sunlight absorption, which means more power and better return on your solar investment.
- Eco-Friendly: No chemicals or detergents are needed, just pure water and professional equipment.
- Safe for Your Panels: Gentle on panel glass and coatings, preserving the lifespan of your system.
Which One Should You Use?
If you’re doing a light rinse yourself and don’t mind a few spots, hose water might be okay occasionally. But if you’re looking to protect your system and maximise its output, professional cleaning with deionised water is the best choice.
