Benefits of Cleaning Solar Panels
Can you pressure wash solar panels? Yes, you can. Benefits of cleaning solar panels include –
Improved Efficiency
One of the prime benefits of cleaning solar panels is improved efficiency and performance. Over the years, dirt and dust accumulate on the surface of solar panels, thereby reducing their ability to absorb sunlight. This results in a decrease in energy production, and you have to bear higher energy costs. Thus, clean solar panels remove dirt build-up, absorb sunlight more effectively, and ensure optimal performance of the solar panel system.
Increased Lifespan
Cleaning solar panels through pressure washing increases their lifespan. Damaged solar panels don’t give the needed output, so homeowners need to replace them. Pressure washing solar panels keep them clean, reduce their wear and tear, and extend their lifespan by preventing long-term damage.
Enhanced Aesthetic Appeal
Cleaning solar panels through pressure washing enhances the look of your property. Dirty or damaged solar panels impact the functionality of the home. Keep them clean so that solar panels can go well with your home’s design and produce clean energy for extended years.
Risks and Precautions of Pressure Washing Solar Panels
While pressure washing might seem like a quick and effective cleaning method, it comes with several risks that could damage your solar panels.
Potential Physical Damage
The first risk associated with pressure washing is that it can cause cracks, damage, or scratches on the solar panels. Such imperfections compromise the integrity of the solar panel and reduce its efficiency. The force of the pressure washing can even damage the seals and frames of the panels.
Water Intrusion
The water can go into the internal components of the solar panels, which can result in corrosion or electrical issues like short circuits. It is best to rely on professionals for such scenarios. Expert pressure washing services in San Diego ensure that water is applied at safe pressure to prevent internal damage and avoid costly repairs.
Warranty Concerns
Many solar panel manufacturers’ warranties do not cover damage resulting from improper cleaning methods, including pressure washing. Using a pressure washer may void the warranty, leaving the owner responsible for any repairs or replacements.
Alternative Methods for Cleaning Solar Panels
If pressure washing isn’t the best option, what are the safer alternatives to clean your solar panels without risking damage? Let’s find out –
Soft Cloth and Water
A microfiber cloth with plain water is one of the safest ways to remove dust and light grime.
Garden Hose
A gentle spray from a garden hose can rinse off loose debris without high-pressure risks.
Gentle Detergents
For stubborn stains, a mild soap solution can help, but avoid abrasive cleaners.
Rain
Natural rainfall can wash away light dust, though it may not remove built-up grime.
Robotic Cleaners
Automated cleaning systems are becoming popular for large solar farms, offering a hands-free solution.
Each method has its pros and cons, so choose the one that best suits your panel type and cleaning needs.
Tips for Maintaining Clean Solar Panels
How do you decide whether to power wash solar panels or clean them using any other method? Here are some tips to maintain clean solar panels –
Schedule Regular Inspections and Cleanings
Regular maintenance helps identify and address issues before they affect performance.
Avoid Cleaning During Peak Sunlight Hours
Cleaning during cooler parts of the day prevents thermal shock, which can crack the panels.
Ensure Safety
Use appropriate safety gear and equipment when cleaning panels, especially those installed on rooftops. If unsure, hire professionals to perform the task safely.
