Soft Washing Vs. Pressure Washing: What's Best for Solar Panels?
May 20, 2025
Solar Panels are a significant invest, providing clean energy and reducing electricity bills. However, to maintain their efficiency and longevity, regular cleaning essential. A common question arises: Should you opt for soft washing or pressure washing? Choosing the wrong method can lead to irreversible damage, reduced efficiency, and voided warranties.
The Risks of Pressure Washing Solar Panels
Pressure washing involves using high-pressure water jets to remove and dirt and grime. While effective for hard surfaces like driveways, it's unsuitable for delicate solar panels due to several reasons
- Physical Damage:
The intense pressure can crack or shatter the glass surface of solar panels.
- Seal Compromise:
High-pressure water can breach the seals around panels, leading to moisture ingress and potential electrical failures.
- Warranty Voidance:
Many manufacturers specify that using pressure washers voids warranty
Why Soft Washing is the Best Choice
Soft Washing is a gentle cleaning method that uses low-pressure water combines with specialized, eco-friendly cleaning solutions. Here why it's the preferred choice for solar panels:
- Safe Cleaning: The low-pressure approach prevents damage to the panel's surface and underlying components.
- Effective Dirt Removal: The cleaning solutions break down and remove organic matter like bird droppings, pollen, and algae, which can accumulate and reduce efficiency.
- Maintains Efficiency: Regular soft washing helps maintain optimal sunlight absorption, ensuring maximum energy production.
