Solar panels are a great way to generate green energy and reduce your carbon footprint. However, the efficiency of your solar panels can decrease if they are dirty and dusty. That is why it is important to clean your solar panels regularly, especially in the summer months.
There are several reasons why solar panels become extra dirty in the summer. First, there is often more dust and pollen in the air, especially during dry periods.
These particles can build up on the surface of the solar panels and reduce the amount of sunlight the panels can receive.
The less sunlight is absorbed by the panels, the less electricity your solar panels can produce. In addition, there will also be more bird droppings in the summer.
Birds find solar panels attractive resting places and use them as lookouts. Unfortunately, their droppings can cover the solar panels and reduce efficiency.
In addition, bird droppings contain acids and other chemicals that can damage the panels and hinder energy production.
10% loss of efficiency
An independent study shows that solar panels lose 10% efficiency if they are (very) dirty. Unfortunately, rain showers are not enough to wash away all the dirt such as bird droppings.
If it does not rain for a long time, dirt can accumulate and form a layer on the surface of the panels. This layer can reduce the amount of sunlight absorbed by the panels.
In addition, the dirt on the panels can increase the temperature and increase the risk of overheating, which can shorten the lifespan of solar panels.
This is how you clean solar panels
To get the most out of solar panels and achieve the highest possible return, it is therefore essential to clean them regularly, especially in summer. Here are a few tips for cleaning your solar panels:
First, check the manufacturer’s safety instructions and, if necessary, call a professional to do the job.
Clean the panels early in the morning or late in the evening when the sun is less intense. This way you minimize the risk of damage due to temperature differences.
Do not use abrasive materials or aggressive cleaning agents as these may damage the surface coating of the panels. A soft brush, a sponge, and some mild detergent mixed with water are usually sufficient.
Rinse the panels thoroughly with osmosis water to free them from soap residue and dirt.
However, you will run an increased risk if you clean the panels yourself and do not have them cleaned by a professional, such as damage due to not using the correct materials and resources, risk of falling and the warranty may be void if you do not adhere to the manufacturer’s instructions.
Professional specialists can be a solution
If solar panels are difficult to reach, if you are unsure of the correct cleaning procedure, or if you prefer not to have to climb onto a ladder or roof, call in a professional cleaning company that has experience in cleaning solar panels.
We recommend concluding a service contract with a professional; this is often also possible with the installer himself.
With a service contract, your panels are cleaned periodically by a specialist. And for a fixed price, this is affordable, and don’t be shocked if the prices are much higher in six months’ time!
Hiring a specialist has the following advantages:
- You can be sure that the cleaning work is carried out correctly
- You do not have to invest in (expensive) cleaning products and equipment
- You run no risk of falling from a ladder or roof
- No risk of damage to the solar panels
→ If you do business with an external party, first read the reviews online such as on Google and Trustpilot. This way you can be sure that you are dealing with a professional and not a cowboy.
By keeping your solar panels clean, you optimize energy yield and extend the lifespan of your system. A little effort and regular maintenance can keep solar panels working efficiently throughout the summer. So, invest in cleaning your solar panels and continue to enjoy the benefits of green energy!
