Cleaning Solar Panels

Why Do Solar Panels Need Cleaning?

Solar panels transform sunlight into energy we can use. For this to happen, the panels’ photovoltaic cells need to capture the sun’s rays. 

But when dirt, debris, or grime cover these cells, the panels might not work as efficiently. 

In fact, the National Renewable Energy Laboratory found that such obstructions can cut solar panel efficiency by 7%.

The good news? Fixing this is simple. But before we dive into the sparkling part, let’s go through things that could affect your solar panels.

How Your Location Affects Your Solar Panels

Have you ever paused to consider if the place you call home impacts the care your solar panels need? It absolutely does. 

Different places have unique issues, but knowing them helps keep your panels shiny and working well. Let’s delve into some specifics.

Dusty Areas:

Places like deserts or those near construction sites are classic examples. These areas have a whirlwind of fine dust and sand. Over time, this airborne debris can accumulate on your solar panels, sometimes forming a thin veil, and at other times, a more pronounced layer. 

If you happen to reside in such a dusty region, it’s wise to inspect your panels regularly. Depending on the dust levels, you might find yourself cleaning them weekly, especially during windy spells. Just to ensures they remain efficient, soaking in all the sunlight they can.

Birdy Places:

Think about locations close to the coast, lakes, or large trees – places where birds thrive. Birds, while delightful, have a habit of leaving behind droppings on surfaces below, including your solar panels. 

These droppings, aside from being unsightly, can also obstruct sunlight. If you notice any, it’s REALLY IMPORTANT to clean them immediately. Depending on bird activity, you might need to check and clean your panels more often, especially during seasons when birds are most active.

Polluted Cities:

Big cities with lots of traffic and factories can make cleaning solar panels harder.

Smog, exhaust, and general city grime can gradually build up on your solar panel surfaces. It’s a good idea for city dwellers to give those panels a comprehensive clean every month or so to ensure they remain grime-free and efficient.

Snowy Spots:

If you’re nestled in mountain regions or places known for their frosty winters, snow is another factor. A thick blanket of snow can completely obscure your panels. When this happens, clean them immediately.

On a snowy morning, arm yourself with a soft broom and gently brush off the snow, taking care not to scratch the panels. This ensures they can get back to their primary function: harnessing the sun’s energy.

The Best Way to Keep Your Solar Panels Sparkling

Solar panels are a great investment in your home and the environment. Like all things, though, they gather dust and need cleaning. Fear not! Keeping them shiny and efficient is a breeze. Here’s a simple guide to doing it right:

Safety First

When dealing with solar panels, especially if they’re on your roof, always prioritize safety. It might sound obvious, but make sure you’re steady on your feet if you have to climb up. 

Using a secure ladder and wearing slip-resistant shoes can make a big difference. If heights aren’t your thing, or if you’re unsure, it’s completely okay to seek help or hire a professional.

Gentle Cleaning:

Solar panels are durable, but that doesn’t mean they can’t get scratched. When cleaning, the key is to be gentle. 

A soft cloth or sponge usually works wonders for removing the usual grime. If you encounter a stubborn spot, like bird droppings, a soft brush can be used. 

But remember, be gentle so as not to scratch the surface.

Mild Soapy Solution:

You don’t need to resort to strong chemicals to get the panels clean. In fact, a simple mix of dish soap and water is all you need. This mild solution is perfect for removing common dirt and won’t harm the panels.

Rinsing Off:

After the soapy treatment, it’s crucial to rinse off any residue. Using a regular garden hose is a good way to do this. Just ensure the water pressure is gentle to avoid any damage.

Easy Tips to Take Care of Your Solar Panels

Taking proper care of your solar panels will maximize their lifespan and efficiency. Here are ten simple tips for maintaining them:

Keep Them Clean:

Dust and debris can accumulate on the surface. Clean the panels with a soft cloth or a sponge and mild detergent to ensure they work efficiently.

Monitor Shade:

Trees grow and new structures can be built. Periodically ensure that no new shade is falling on your panels.

Regular Inspections:

At least once a year, check for any visible damage or wear and tear.

Use Soft Water:

If you use water to clean the panels, ensure it’s soft water to prevent mineral buildup.

Avoid Abrasive Tools:

Never use harsh brushes or scouring pads, as they can scratch the panels.

Check Inverters:

The light on your inverters should be green. If not, there might be an issue with energy production.

Keep the Area Clear:

Ensure that the area around your ground-mounted solar panels is free of debris, plants, or any other obstructions.

Professional Check-up:

Have an expert check your panels every few years to make sure everything’s working right.

Monitor Output:

Keep a regular eye on the power output. A significant dip can indicate an issue that needs addressing.

Safety First:

If you decide to clean or check the panels yourself, ensure you follow safety guidelines, especially if they are roof-mounted.

When to Think About Hiring Professional Solar Panel Cleaners?

Cleaning solar panels might seem like a simple task, but sometimes it’s worth reaching out to the experts. One of the main reasons homeowners choose professional services is the promise of better efficiency. 

Professionals use the most current cleaning techniques, ensuring that post-cleaning, your panels can capture sunlight to their maximum potential.

Safety is another big concern. The idea of climbing on the roof and working at heights can be daunting for many. Professionals are trained to handle these situations, to clean safely and efficiently.

The risk of unintentional damage shouldn’t be underestimated either. Imagine accidentally causing a scratch or damaging a part while trying to clean. 

Now, let’s talk about warranties. Some manufacturers have specific conditions related to maintenance, and in certain cases, they might require regular professional cleaning to ensure the warranty remains valid. 

There’s undeniable peace of mind that comes with hiring professionals. Knowing that your solar investment is being cared for by experts gives homeowners a sense of relief. 

For longevity, efficiency, and peace of mind, professional solar panel cleaning is a worthy consideration.

Maximizing the Return on Your Investment

Maintaining the cleanliness of your solar panels is essential. Just as a car performs better with regular maintenance, solar panels need cleaning for optimum performance. 

Dust, debris, and bird droppings can reduce their efficiency. It’s not all about appearance; it directly impacts your energy output. 

Regular cleaning ensures your panels deliver the best results, maximizing the return on your investment. Stay ahead of the game; regularly clean your panels to guarantee consistent and efficient energy output for the long haul.
