Maximize Solar Panel Efficiency!

The use of solar panels is rapidly gaining popularity as a sustainable energy source. As they absorb sunlight, they create a current that’s converted into a renewable energy: solar power. The benefits of solar energy are numerous, including decreased energy costs, reduced carbon footprint, and enhanced aesthetic and curb appeal for your home. However, all of these positive, productive attributes are redundant if solar panels on your home or business property are filthy. Rain is not effective in cleaning extremely dirty panels, unlike mud stains. Although rain can effectively wash away dirt and debris, it may require additional effort to tackle stubborn grime. Solar panel owners in Portland can benefit from regular cleanings offered by Total Window Cleaning Inc.

Stay with us as we take a deeper look at what our company does for solar panel maintenance.

Maximize Solar Panel Efficiency

Solar power systems are incredibly low-maintenance compared to other forms of power generation because they generate electricity without any moving components. Although preventative maintenance is key, and the solution? A cleaning process offered by our professional cleaners here in Portland. Our team of highly skilled professionals provides an effective cleaning solution tailored for your solar panels, ensuring that they continue generating green energy at optimal efficiency.

Brush Away Dried-Up Dirt and Residue

Cleaning solar panels is fast and efficient when they are not very soiled. However, using water to wash them is ineffective when there is a significant amount of dust and grime. The combination of water and dirt forms mud, which can dry on the panels. We’ll use solar panel cleaning equipment such as soft brush (soft-bristled brush is best) to remove dried-up dirt, bird droppings, and various debris when the panels have dried. 

Washing Panels With Clean Water

After clearing away the buildup of dirt, you can give your panels a thorough wash to eliminate any lingering dust and particles. It’s important to use clean water, and we recommend using soft washing services instead of high-pressure nozzles on the panel surface. The best part is, you won’t even need to wipe down your panels as the water will naturally evaporate on its own.

Remove the Remaining Loose Dirt

When your solar panels are excessively dirty, a simple brushing and washing may not suffice to ensure a thorough clean. We will diligently target problem areas with water and mild soap, avoiding the use of harsh detergents and strong cleaning agents. Here in Portland, it’s important to use a spot-free system due to the minerals in our water. 

Maintaining Your Solar Panels Between Cleaning Appointments

Maintaining solar panels goes beyond mere cleaning. It is important to regularly monitor energy production to detect any electrical issues. Thankfully, many solar inverters come with a monitoring app designed for homeowners. By using this app on your smartphone, you can keep track of daily power generation. It is important to note that low productivity is to be expected in certain weather conditions, as solar panels are exposed to limited sunshine. Nevertheless, if the monitoring app indicates lower-than-average electricity output on a sunny day, it is advisable to contact your solar provider. Keeping your solar panels clean on a regular basis is crucial for maintaining optimal performance and ensuring that your system generates the expected amount of electricity. When your solar energy system is dirty, it operates less efficiently, leading to higher energy bills. Professional solar panel cleaners refer to this efficiency loss as “soiling losses,” which is caused by the accumulation of dust and dirt on your PV system.

Total window cleaning quoted me $410 price to clean my windows at a property I am selling. After they said they were done, I was billed $675. Some of the exterior windows were not clean. The owner was rude and aggressive and clearly not interested in honoring the agreement. Terrible experience!

FAQs Regarding Solar Panel Cleaning in Portland, OR

Why should my solar panels be cleaned?

As time goes by, various substances can gradually accumulate on solar panels, reducing the amount of sunlight they receive and ultimately leading to a considerable decrease in efficiency. This issue is even more pronounced for horizontal panels, as they lack the natural cleaning effect of rain. Regularly cleaning solar panels not only helps them maintain their maximum efficiency but also extends their overall lifespan. Neglecting to clean the panels on a regular basis may even result in homeowners voiding their solar panel warranty.

How frequent should solar panels be cleaned?

Homeowners often wonder how often they should clean their solar panels. Typically, once or twice a year is sufficient, but the frequency can depend on several factors. For instance, regions with low rainfall may require more frequent cleaning, as well as homes with low-slope roofs. In Portland, due to our frequent rainfalls, cleaning about once a year should be sufficient. However, if there is nearby construction in your neighborhood, it may be necessary to remove settled dust. It’s crucial to consider the timing of the cleaning, as panels should be relatively cool to avoid issues such as water evaporation or panel cracking. Optimal times for cleaning are in the morning or evening, on cloudy days, or during mild spring and fall weather.
