We analyzed the main recommendations for cleaning operations presented by the 10 largest solar panel manufacturers in the world - Longi, Jinko Solar, Trina Solar, JA Solar, Canadian Solar, Risen Energy, Astronergy, First Solar, DMEGC Solar, QCells.

What the Top 10 Largest Solar Module Manufacturers Say about PV cleaning

In the field of professional cleaning and maintenance in the solar industry, the search for the best performance, quality and efficiency is a constant concern for professionals. Whether it's tricky dirt on the solar panels, such as lichen or paint splashes, or using the right cleaning solutions in the right way and in the right doses for effective cleaning, having the right equipment can make all the difference.

Top professional tools to optimize solar cleaning

In the quest to harness solar energy, solar panels are at the forefront, silently battling an implacable enemy - soiling.

Cleaning Solar Panels: Top 5 Soiling Challenges

Solar panels like most technologies, are not immune to issues, that can impact their performance and longevity, nor maintenance free.

Top 5 Robots for Solar Cleaning

In the maintenance and cleaning sector of solar panels, a primary consideration arises from the penetrating nature of per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals". Given the widespread applications of PFAS in various industries and products, it is imperative to stress the importance of choosing solar cleaning chemicals that do not contain these persistent substances.

PFAS-Free Solutions in Solar Panel Cleaning and Protection

The global issue of soiling in photovoltaic (PV) plants has emerged as a major challenge, significantly affecting energy production and resulting in global losses estimated at 3% to 5%. Dirt has a significant impact on photovoltaic plants, and innovative strategies are needed to mitigate its effects.
Anti-soiling coatings (ASC) are therefore specifically designed to mitigate the impact of soiling and dirt on solar panels.

Cement Removal Agent - How to Remove Cement Dust Cured on Glass

The production of cement, being a very fine powder, creates a lot of dust emissions throughout the process. Even the all the efforts of containing those emissions with filtration systems, the dust is so fine that it able to escape through the tinniest gaps. When this dust mixes with dew overnight, a cementation process begins that cures the layer of cement dust on top of the modules.
