Photovoltaic systems cleaning: How to hire the right company

 

Photovoltaics (also PV systems or solar systems) offer an environmentally friendly alternative to energy generation via natural solar radiation. However, solar systems are subject to various environmental influences pollute the weather. This can significantly reduce their performance. For this reason, regular cleaning of photovoltaic systems is recommended.

However, this project is associated with several questions: should photovoltaic systems be cleaned? How can I clean a photovoltaic system? Which methods and cleaning agents are useful for solar systems? How many does it cost to clean a photovoltaic system?

Today we bring light into the darkness and have answered the most important questions about cleaning photovoltaic systems briefly and precisely in a blog post. Find out more about the efficient operation and ‌maintenance of your solar modules.

What pollutes solar panels?

The type and ‌pollution can vary ‌depending on the location and current environmental influences.

Rain, snow, dust, dirt, pollen, leaves, moss, netting, small branches and many other indicators eventually lead to deposits on the surface of the solar modules.

In years with a high pollen count or larger agricultural activities in the vicinity, contamination can lead to faster and more severe impairment of the photovoltaic systems.

Should you clean photovoltaic systems?

Definitely, because dirt can partially cover the solar cells. Sunlight is then no longer converted into electricity in ‌​​the soiled areas.

The solar module becomes useless in parts or does not achieve the desired efficiency. The system’s yield is significantly reduced‌.

In addition, dirt such as moss or leaves on the edges of the photovoltaic system significantly shortens the service life and can lead to high investment requirements.

Photovoltaic systems should be cleaned of dirt regularly in order to achieve the desired energy yield under optimal conditions.

Even a medium ‌soiling can lead to a reduction in yield of up to 20%. With a photovoltaic system cleaning, you ensure that the yield is maintained and automatically increases the profitability of the photovoltaic elements.

In this context, the question of how the special cleaning can be implemented and what special features have to be considered is interesting.

How can I clean a photovoltaic system?

PV systems can also be cleaned by yourself, especially if they are slightly soiled. However, in most cases the support of an experienced service provider makes sense.

Because it is not uncommon for the danger, for example, when cleaning photovoltaic systems on roofs (including injuries, falling) to be underestimated and owners resort to the wrong cleaning methods and agents, which damage the solar modules or render them permanently unusable.

In addition, stubborn dirt can also be a real problem. If these are not removed completely or incorrectly because of a lack of experience, the yield will be restricted.

We should use which methods and cleaning agents for solar systems?

We should clean as gently photovoltaic systems as possible. A professional in this field takes over the job with the right equipment and the associated cleaning agents or relies on modern processes.

No harsh cleaning agents are used, but environmentally friendly cleaners and cleaning tools, including special glass brushes. When cleaning with a high-pressure cleaner, however, extreme caution is required. Depending on the high-pressure cleaner, cracks and fissures can quickly appear in the glass surfaces, leading to permanently irreparable damage.

In addition, in many regions, it is not advisable to use hard water from the tap, because ‌the hardness of the tap water determines how strong ‌lime deposits can be on the solar modules. Here, too, there is a risk of damage in the event of improper implementation in practice.

In this context, the use of osmosis devices has proven itself, which do not require classic cleaning agents and become active using reverse osmosis with demineralized water.

How often should the photovoltaic systems cleaning be carried out?

How regularly a professional cleaning of a photovoltaic system should be carried out depends‌ on the location and the pollution caused by dirt on site.

In most cases, cleaning once a year is sufficient to reliably remove all residues and dirt. The situation can be different near farms, where heavy pollution can occur in the immediate vicinity.

How much does it cost to clean a photovoltaic system?

The costs for cleaning solar systems depend on the regularity, the size of the area to be cleaned, but also on factors such as accessibility or ‌soiling.

In order to ‌estimate the costs correctly in advance, a cost estimate makes sense. You can request this directly from the provider of your choice free ‌and without obligation.

Simply describe the conditions on site and the special features of the solar system, ‌contamination or the time the photovoltaic system was last cleaned.

How do I commission the right company to clean photovoltaic

Set featured image systems?

The best way to find experienced service providers in your region is via the Internet. There you can not only get a first impression of the range of services and references of the company but also directly request a suitable offer via the online contact form.

It can often be useful to inspect the PV systems in advance in order to give the client the opportunity to get a concrete picture of the solar modules and the contamination associated with them.

You can discuss all the important points together and the professional cleaning service provider will make you a suitable offer and suggest dates.

This way you are on the safe side and avoid unplanned costs. However, they can also define the time frame for implementing the photovoltaic system cleaning.

Conclusion: This is how you can have the photovoltaic systems cleaned professionally!

After reading our article, you will know why it is important to care for the solar elements and what is important with cleaning photovoltaic systems.

In addition, you know the advantages of hiring a professional cleaning service provider and have learned how the costs for cleaning solar systems are made up.

In addition to the ‌frequency and gentle cleaning process, special equipment is used that gently but also reliably removes contamination and thus enables efficient operation of the solar system.

The aim is to ensure the full performance of your PV systems in order to generate environmentally friendly electricity. An adapted cleaning enables the service life to be extended and thus the avoidance of unplanned maintenance costs.
