Lichen Stain Removal Agent
Biodegradable cleaner for lichen, moss and algae stains and extreme organic soiling on solar panels.
If you're a solar plant owner and you live in a humid region, you've probably seen organic soiling and staining build up on your panels, such as the marks left by lichen, moss and algae. Not only does it look unappealing, but it also decreases the performance of your solar panels. Until now, removing this kind of soiling has been a challenge for O&M teams and asset owners, as the use of scrapers, high pressure surface cleaners and aggressive chemicals voids the panels' warranties while also being highly damaging to them.
But now, there is a solution that can clean this soiling from your solar panels without damaging them. The Lichen Stain Removal Agent (LRA) by Chemitek.

Certified for solar panels by ÉMI-TÜV Süd
The international laboratory ÉMI-TÜV Süd, recognized for their solar panel certification services, has certified the LRA as safe for solar panels. This certification assures that the use of the LRA does not damage the panel's components (e.g. aluminium frame, anti-reflective coating and silicone seals) and does not interfere with light transmission.
Approved by PV manufacterers
The Lichen Stain Removal Agent has letters of conformity from the top PV manufacturers:
- Longi
- JA Solar
- Runergy
- First Solar
- Hyundai Heavy Industries
- Astronergy
If you're looking for an easy, safe, and cost-effective solution for cleaning lichen, moss and algae stains from your solar panels, LRA is the product for you. With its proven effectiveness, environmental safety, and warranty compliance, it's a must-have for any solar panel owner.
Easy Application
Lichen Stain Removal Agent is easy to apply, saving you time and resources. All you need to do is dilute it with water (1 kg per 10 L), spray it onto your solar panels, allow a short contact time, then brush and rinse to remove the loosened soiling. The deposits will become less attached to the surface of your solar panels, making them easier to lift away.
Safe and Effective
LRA is a safe and effective solution for cleaning lichen stains from solar panels. Unlike aggressive chemicals and scrapers, LRA won't damage your solar panels. This agent is designed to be as delicate as possible with the components of the solar module (ARC, silicone and aluminium frame). The product helps break the bond between the soiling and the solar glass, making the deposits easier to remove, so you won't have to worry about voiding the warranty. And because it is a biodegradable product, it is safe for the environment and won't harm nearby plants or animals.
Cleaning product only — not a biocide or pesticide.
Cost-Effective
Using LRA is a cost-effective solution for cleaning lichen stains. As it doesn't require significant human resources or aggressive chemicals, it saves you money in the long run. Additionally, by keeping your solar panels free from stains and organic soiling, you will improve their efficiency and prolong their lifespan, meaning you will save money on maintenance and replacement costs.

FAQs
The surface of photovoltaic solar panels must be clean to ensure full operation and maximum performance. Any kind of soiling that may be on the surface of the solar module, be it dust, pollen, tree sap, bird droppings, sand, salt crystals, etc., will reduce the light transmission, i.e. reduce the amount of sunlight reaching the solar module cells, and thus the panel will produce less energy.
To the naked eye the panels may appear clean, however there will be soiling accumulated, even if it is just the air pollution itself. A simple test to see if your panel is in need of cleaning is to wipe the surface of the panel with a white cloth or cotton pad before the actual cleaning.
According to recent studies, when a solar panel is very dirty it can lose up to 50% of its performance compared to a clean solar panel. However, the worldwide average energy loss due to soiling is 3 to 5%.
In fact, rain or wind will not keep the panels clean. Wind will carry particles that will settle on the panel and rainwater is not enough to remove any incrusted soiling such as bird droppings or pollen. Rainwater can even lead to the appearance of hotspots by accumulating the soiling on the bottom frame of the panels.
For the warranty on your solar panel to remain valid, you should use solar panel cleaners that meet the manufacturers' guidelines and are certified for solar panels, such as Solar Wash Protect. This means that the products need to be pH neutral, biodegradable and environmentally friendly and have been tested by international laboratories, such as ÉMI-TÜV Süd.

LRA cleans lichen, moss and algae stains from solar panels. Due to its cleaning power, it is also highly effective on extreme organic soiling.
LRA is a biodegradable product designed to be as delicate as possible with the components of the solar module (ARC, silicone and aluminium frame). The product helps break the bond between the soiling and the solar glass, making the deposits easier to remove. In case of doubt, contact us.
To keep panels cleaner for longer and easier to clean, protect them afterwards with a hydrophobic coating such as the D-Solar Defendor from Chemitek.
No. LRA is a cleaning product, not a biocide or pesticide, and it contains no biocidal or antimicrobial active ingredients. It works by physical/detergent action — its surfactants loosen the deposits and reduce their adhesion to the glass, so lichen, moss and algae stains and organic soiling can be removed by brushing and rinsing. It does not kill, control, prevent or otherwise act on any living organism; mechanical cleaning (brushing and rinsing) is always required to remove the soiling.
