Photovoltaic systems and modern solar technology need clean modules for maximum efficiency. However, conventional monitoring and cleaning solutions are often expensive, labor-intensive, and ineffective.
sun-X offers patented, cutting-edge PV technology for this purpose. Over 14 years of solar cleaning experience from founder Pascal Liebold flows into every development – for intelligent, field-tested solar technology from the field, for field deployment.

With the founding of PV-Liebold GmbH, our journey began as a provider of solar cleaning services. Our goal in Germany and neighboring European countries: Maximum performance of photovoltaic systems through efficient cleaning.
Development and market launch of the modular cleaning robot sunbotics. Through its modular system with conversion options from 1.10 meters to 2.50 meters and conversion as a hanging system, up to 4.20 meters, it sets new standards in solar cleaning as a technology leader.
Our technology portfolio became intelligent: sun-X expanded its developments with sensors, data analysis & AI to determine the ideal cleaning time for solar systems and minimize maintenance costs.
In 2025, sun-X is developing fully autonomous cleaning and maintenance systems for photovoltaic installations.
The focus is on advancing intelligent sensors and robust robotics – with the goal of operating PV systems efficiently, data-driven and without human intervention worldwide in the long term.
Use smart PV soiling monitoring & autonomous cleaning for more yield, easiest maintenance, and effective cost minimization for all types of photovoltaic systems.
