Solar Panel Cleaning: Natural, Professional and Increasing Efficiency

Solar Panel Cleaning: Natural, Professional and Increasing Efficiency

Find out how solar panel cleaning naturally and professionally increases your energy yield, extends the lifespan and protects your investment.

Solar panels are a crucial investment for those opting for renewable energy. However, over time, dirt, dust, bird droppings, leaves and other deposits can accumulate on the panels. This not only reduces energy yield, but can also negatively affect the lifespan of the installation. In this article, we elaborate on the importance of cleaning solar panels, we explain how Solarco does this naturally and professionally and discuss the transparent prices we charge. We also provide useful internal and external links so that you are well informed about everything related to solar panel cleaning.

Why Clean Solar Panels?

Maximum efficiency and energy savings

Cleaning solar panels is essential to ensure maximum energy yield. Dirt and deposits cause less sunlight to hit the solar cells, which can result in a loss of efficiency of as much as 5 to 10%, and in extreme cases even more. So regular solar panel cleaning ensures that each solar cell regains its optimal performance. This not only means that you generate more energy, but also that your energy bills can drop significantly. From studies and publications, such as those by HLN and Test-Achats, shows that a clean solar panel system contributes to higher efficiency and a shorter payback period for your investment.

Extended Lifetime

Besides increasing efficiency, regular solar panel cleaning also extends the life of your installation. Dirt, sand and other particles can cause damage over time, such as corrosion or micro-scratches on the panels. By removing these contaminants, you minimise the risk of damage and prevent small problems from growing into expensive repairs or even a complete replacement of the panels. This protects your investment in the long run.

Enhanced aesthetics and value retention

An added benefit of regular solar panel cleaning is that your installation looks neater and more attractive. This can be especially important if you want to sell your home or commercial property. Potential buyers are more likely to trust a well-maintained and clean installation. Moreover, a clean installation exudes professionalism and care, which will enhance your reputation as a sustainable business owner.

Natural Cleaning without Harmful Agents

At Solarco, we value a natural cleaning method. We use osmosis water, a demineralised form of water that is free of lime, salts and other impurities. This ensures that no chemical residue is left on your solar panels, improving both their performance and service life. Using osmosis water means you are investing in maintaining your renewable energy supply in an environmentally friendly way.

Solarco's working method for solar panel cleaning

At Solarco, professionalism and customer satisfaction are key. Our process is designed to clean your solar panels thoroughly and safely, with a focus on natural cleaning and maximum energy yield. Below is a step-by-step overview of our process.

1. Thorough pre-inspection

Before we start cleaning your solar panels, our experts carry out a comprehensive pre-inspection. Here, we look at:

  • The current state of the panels
  • The extent and nature of pollution
  • Any damage or loose parts

This inspection allows us to draw up a tailor-made cleaning plan. If you want to know more about our approach, visit our page have solar panels cleaned.

2. Preparation and safety measures

Solar panels are often located on roofs or other hard-to-reach places. Safety is our top priority. That is why we provide:

  • Proper safety equipment (such as fall protection and sturdy ladders)
  • Clear planning so that our technicians can work efficiently

These preparations ensure that the cleaning process is not only thorough, but also safe.

3. Professional Cleaning with Osmosis Water

Our core method in solar panel cleaning is to use osmosis water. What makes osmosis water so suitable?

  • Purity: Osmosis water is completely demineralised, leaving no lime, salts or other minerals behind. This ensures a streak-free and clear result.
  • Of course: Because we do not use harsh chemicals, the cleaning method is completely environmentally friendly.
  • Effective: The osmosis water completely dissolves dirt and deposits, allowing your solar panels to absorb sunlight optimally again.

During the cleaning process, we use a soft brush attached to a long, extendable handle. This allows us to reach all parts of the solar panels, even on high or hard-to-reach roofs. We start with a pre-treatment for stubborn stains, after which osmosis water is carefully applied and then rinsed off.

4. Aftercare and Advice

After cleaning, our technicians check the panels again to ensure that all dirt and deposits have been completely removed. We will then advise you on:

  • How to tackle light soiling yourself between professional cleanings
  • The ideal frequency of professional cleaning (with us, we recommend at least once or twice a year)
  • Possible concerns for your specific installation
