Your photovoltaic installation can work more efficiently than ever – under one condition: it must be cleaned regularly. At Helios Energy, we specialize in professional cleaning of large PV systems, servicing solar farms and industrial rooftops throughout Luxembourg.
We work quickly, effectively, and sustainably, using only demineralized water and advanced cleaning equipment. We ensure our clients achieve maximum energy production with minimal effort on their part.

Organic residues, dust, soot, bird droppings – these are invisible enemies of your solar system. In practice, they can reduce performance by up to 30%, cause uneven module heating (hotspots), and shorten the system’s lifespan over time.
Panel cleaning is not an expense – it's a smart investment. Regular maintenance not only restores output but also prevents costly breakdowns and energy loss. Helios Energy treats your panels like our own. We follow top O&M (Operations & Maintenance) standards, using only demineralized water without chemicals. As a result, you get spotless panels, free of damage or cleaning traces.
Choose efficiency and cleanliness. It simply pays off.
Helios Energy is a trusted partner for industrial and institutional clients managing PV systems ranging from hundreds of kilowatts to several megawatts. We service large solar farms, production halls, warehouses, and logistics centers. With experience and cutting-edge equipment, we are ready to work on any surface type.
No location is too difficult – we use lifts, rope access techniques, and mobile cleaning machines. Our services are fully tailored to your needs, from one-time cleanings to ongoing service agreements.
If you're responsible for PV systems in a company, municipality, or institution – trust the specialists. Choose quality that translates into results.

At Helios Energy, we value your time, which is why we simplified our process into three easy steps:

Contact & Analysis
Get in touch and send us basic information about your installation: location, type of facility, approximate capacity and surface area. Then we’ll schedule an on-site inspection at your convenience.

Inspection & Quote
During the visit, we assess the level of dirt, technical conditions, and choose the most effective cleaning method. Based on this, we prepare a personalized offer.

Execution & Report
We carry out the cleaning and, if needed, provide a detailed report.
Cleaning PV modules requires more than just goodwill – it demands the right tools. At Helios Energy, we use advanced equipment specifically designed for solar panel cleaning. This ensures not only effective dirt removal but also safety and damage prevention.
For solar farms, we use SunBrush systems and mobile vehicle-mounted machines. For rooftop systems, we use telescopic brushes with demineralizers and rope access techniques where needed.
All our staff are trained in occupational health and safety, working at heights, and electrical system procedures.
Your investment’s safety is our priority.

Clean panels aren’t just about aesthetics. They deliver measurable results – increased energy yield, better efficiency, and lower losses during peak sunlight. Our clients see production gains of 10% to even 30% after professional cleaning. Regular maintenance also reduces the risk of hotspots, voltage drops, and other issues caused by uneven contamination.
See the results for yourself – we provide photo documentation (before and after), reports, and performance comparisons (if client data is available). Example?
