Why Do Solar Panels Need Cleaning?

To maintain their performance and reliability, solar panels require regular cleaning. While they are typically installed with a tilt to self-clean via rainwater, periods of drought in some places can lead to the accumulation of dust, bird droppings, and other pollutants. Nearby deciduous trees not only shed leaves but also attract birds, further contributing to the build-up of debris that can obstruct sunlight and significantly reduce the efficiency of your solar panels. It's essential to regularly clean solar panels to ensure they generate power at their maximum potential, as any obstruction can significantly impact their electricity production capabilities.

When Should Solar Panels Be Cleaned?

Take the harsh climate of Africa as an example. It is recommended to clean the solar panels at least once every six months. However, this can vary based on several environmental factors. If you're experiencing extreme conditions such as fires, dust storms, or excessive rainstorms for prolonged periods, more frequent cleaning may be necessary. Homes near highways, construction sites, or coastal areas that are prone to marine layer residue also require more thorough solar panel maintenance due to the higher likelihood of debris accumulation.

Best Cleaning Solution for Solar Panels

Maintaining the efficiency of your solar panels entails proper cleaning. Here are four of the best cleaning solutions for solar panels:

1. Rinse with a Low-Pressure Washer: The first stop on the best solar panel cleaning solution is a quick rinse with a low-pressure washer. It can effectively take care of the layer of dust and dirt on your PV solar panels. It's important to retain low pressure so that the panels are not scratched or damaged.

2. Wash with Soapy Water: For a more thorough wash, a combination of water and mild soap does the trick. This not only cleanses your panels but also avoids potential chemical damage. Remember to use a gentle scrubber, rinse off gently, then remove excess water with a squeegee.

3. Professional Service: Another best solution for cleaning solar panels is seeking professional help. If you're unsure of how to clean your solar panels or intimidated by the process, engaging a reputable company that provides professional cleaning services can save you from potentially damaging the system.

4. Consider Hydrophobic Coating: Regular solar panel maintenance can be daunting. A hydrophobic coating can be the best solution to clean solar panels as it offers the convenience of staying cleaner for a longer period of time. This ultra-thin, invisible barrier not only enhances the appearance of your solar panels but also increases their energy output and overall performance by preventing sunlight obstruction caused by debris.

How to Clean Solar Panels Yourself

Here is a step-by-step guide on how to clean solar panels:

Step 1: Prioritize Safety

Before anything else, consider safety first. Ensure you're equipped with a safety harness and/or a hard hat if you must get on the roof. Always remember to work within your limits and only proceed if it's safe.

Step 2: Choose the Right Time

Aim for a cool day for cleaning, as solar panels and roofs can get extremely hot, making the task more challenging and potentially dangerous.

Step 3: Gather Materials

You'll need water, a soft, non-abrasive sponge or cloth, and possibly a mild, environmentally friendly soap similar to what you'd use for dishes. Avoid strong chemicals or corrosive detergents.

Step 4: Cleaning Process

• Wet the solar panels with water to loosen the dirt and debris.
• Gently scrub the panels with a sponge or cloth to remove the debris. If necessary, apply a small amount of soap to aid the cleaning process.
• Rinse the panels thoroughly with tap water to remove any soap residue.
• Dry the panels using a squeegee or chamois to prevent residue streaks.

Step 5: Inspection

The last step in how to clean solar panels is inspection. After cleaning, inspect your panels for any damage, cracks, or nests from birds and rodents. Regular inspections help ensure your panels remain in optimal condition for sunlight absorption, which is essential for maintaining energy efficiency and keeping electricity bills low.

Additional Tips:

Avoid Harsh Cleaning Agents and Tools: Steer clear from strong detergents and abrasive cloths or sponges that can scratch the panel's surface.
Never Stand on Panels: This can cause cracking and is a safety hazard.
Consider CCTV for Easy Monitoring: Installing a CCTV camera to monitor the condition of your solar panels can save you from frequent roof trips and help you decide when cleaning might be needed.

When Should You Call in a Professional?

While regular dust can be washed away by rain, making professional cleaning unnecessary for minor buildups, there are circumstances where hiring professionals is advisable:

Living in heavily polluted or coastal areas: The accumulation of pollutants or marine layer residue might require specialized cleaning equipment or techniques.
Deciduous trees near your panels: If foliage and bird dropping accumulation is significant, professional services can ensure thorough cleaning without damage to your panels.
Tough build-ups: Situations like hardened bird droppings or severe grime may require professional attention to avoid damaging the panels.
Safety concerns: For individuals who are elderly or not confident in safely accessing their roof, professional cleaners can ensure the job is done safely and effectively.

How Much Does It Cost to Hire a Professional for Cleaning?

The cost of hiring a professional cleaner, particularly for cleaning solar panels, largely depends on a few factors such as the size of the solar PV system, the location of the panels, and whether your roof has any unique features that could complicate the job. In general, you can expect professional solar panel cleaning services to charge between R2,000 and R4,000 each time. Hiring a specialist for this task is a worthwhile investment to ensure your panels maintain peak performance and longevity, ultimately saving you large sums of money in the long run by optimizing efficiency.

FAQ

Here are some frequently asked questions about a solar panel cleaning solution.

Does Rain Clean Solar Panels?

Yes, rain can definitely help to clean solar panels by washing away dust, bird droppings, and other types of dirt. However, rainwater may not effectively remove all the debris, particularly sticky substances or residues that may require a more thorough cleaning process.

Can You Walk on Solar Panels to Clean Them?

No, it is highly discouraged to walk on solar panels to clean them. Solar panels are fragile and the weight of a person walking on them could cause significant damage. It is best to clean them from the ground using extendable tools or hire professional cleaners.

What Liquid Is Used to Clean Solar Panels?

The most common and safe cleaning liquid for solar panels is a mixture of warm water and mild soap. This mild detergent solution effectively removes dirt without risking any damage to the solar panel's surface. Always avoid any harsh chemicals or abrasive materials as they could potentially scratch or cause other damage to the panels.
