Our partner GLASKLAR.solar
Professional PV cleaning – for clean solar modules, increased performance and sustainable value retention.
More yield for your photovoltaic system – exclusive benefit for members of EEG WIEN
The EEG VIENNA expands its partner network and is pleased to be partnering with Crystal clear. Solar We are pleased to announce that we have gained an experienced specialist for the professional cleaning of photovoltaic systems as a new cooperation partner. Behind this brand is the well-known Lower Austrian company Mag. Hinteregger GmbH. The aim of this collaboration is to offer EEG WIEN members added value regarding the efficient and sustainable operation of their PV systems.
Photovoltaic systems are an important investment in the energy transition and make a significant contribution to regional, renewable energy supply. For a system to achieve its maximum yield over many years, regular maintenance of the modules is just as important as high-quality technical equipment. This is precisely where our expertise comes in. Crystal clear. Solar to: With state-of-the-art cleaning technology, trained specialists and a sustainable cleaning concept, the company ensures that photovoltaic systems can develop their full potential.

Why is cleaning photovoltaic systems important?
Over time, dust, pollen, soot, bird droppings, moss, and other environmental contaminants accumulate on photovoltaic modules. These contaminants can impair the sunlight reaching the modules, thereby reducing electricity production. Depending on the location, tilt angle, and degree of soiling, noticeable yield losses can occur. Furthermore, soiled modules can develop so-called hotspots, which can negatively impact the system's long-term lifespan.
Regular professional cleaning therefore helps to:
- to optimize electricity yields,
- To reduce performance losses,
- to protect the modules from damage,
- to extend the lifespan of the system and
- to secure the value of the investment in the long term.
Gentle cleaning with osmosis water and special technology
Crystal clear. Solar We rely on modern, professional cleaning technology and use demineralized reverse osmosis water. This highly purified water enables particularly gentle and thorough cleaning without limescale residue. At the same time, chemical cleaning agents are largely avoided, making the cleaning process environmentally friendly and gentle on materials.
Specially developed cleaning equipment with soft, rotating brushes is used to effectively remove dirt without damaging the sensitive module surfaces. The fine water mist made from reverse osmosis water ensures gentle treatment of the modules.
TÜV Rheinland certified quality
Of particular note is the professional and TÜV Rheinland-certified work method of Crystal clear. Solar. The cleaning is carried out according to professional standards by trained specialists and offers plant operators the highest level of safety and quality.
Exclusive benefit for members of EEG Vienna
