Applications of ChemiTek’s solar products - Robot

Solar Wash Protect 50

SWP is a concentrated, biodegradable, and innovative solution designed not only to clean a wide range of organic soiling from your solar panels, but also provides a protective antistatic coating that helps prevent future dirt and debris buildup.

Robot

Spray first:

• dilute the product and spray the solution onto the panels
• brush and rinse simultaneously by turning off the water to the front brush (to brush without water) and rinse with the back brush. This will avoid the need of a second pass to rinse.

Mixed in the cleaning water: in severe soiling problems:

• mix the SWP directly into the cleaning water (the dilution can be between 1:50 and 1:100). We recommend the use of a dosing pump for real time mixing (SWP with cleaning water)
• brush the SWP solution using both brushes
• rinse with pure water. When using a dosing pump with by-pass, to get pure water, you just need to open the by-pass.

SWP as a water additive: SWP will reduce the surface tension of the water, improving its penetration in the dirt thus making the cleaning more effective than just water. No rinsing is required but the antistatic coating left on the modules will be very limited.

• we recommend the use of a dosing pump for real time mixing (SWP with cleaning water) and a dilution of 1:500 (1kg of product for 500L of water)
• clean the modules as you would normally do with just water
• rinsing is not required.

Lichen Removal Agent

Lichen Removal Agent is a removal agent for lichen, moss and fungi designed specifically to be used on solar panels. It is a biodegradable product designed to be as delicate as possible with the components of the solar modules.

Robot

Spray first:

• dilute the product and spray on the panels with a sprayer making sure to soak the complete surface.
• on severe cases, brush the modules without adding water to make sure that the product can reach the glass
• wait 10 to 20 min
• pass the robot to brush and rinse the modules
• if necessary, repeat the steps above

Mixed in the cleaning water: in severe cases:

• mix the product directly into the cleaning water (directly in the water tank or using a dosing pump)
• brush the entire surface with the diluted product
• wait 10 to 20 min
• to rinse, change to the pure water hose, or open the bypass if using a dosing pump, and brush and rinse thoroughly
• if necessary, repeat the steps above

Sprayer on the robot: some manufacturers have the option of a sprayer on the robot, replacing the front brush and covering a bigger area.

• mix the product directly into the cleaning water (directly in the water tank or using a dosing pump)
• spray the diluted product on the entire surface
• wait 10 to 20 min
• remove the sprayer and install the brush
• pass the robot to brush and rinse the modules
• if necessary, repeat the steps above

Cement Removal Agent

Cement Removal Agent is specifically designed to remove cement, stone dust, gypsum and other alkaline contaminants from solar panels without damaging the surface, while significantly reducing the time spent cleaning, the water consumed for cleaning and the costs required to clean the modules.

Robot

Spray first:

• Dilute the product and spray the solution on the panels with a sprayer before the robot passes making sure to soak the complete surface.
• After a few seconds, pass the robot to brush and rinse the modules.

Adding a second hose:

• Attach a second hose with the diluted product to the robot and connect it directly to the front brush.
• With the front brush stopped. spray the product
• The back brush will do the rinsing with water. The robot needs to drive slowly to give time for the reaction of the product with the cement.

Sprayer on the robot: Some manufacturers have the option of a sprayer on the robot, that replaces the front brush and is wider than it.

• Spray the solution using the sprayer making sure to soak the complete surface.
• Reattach the front brush to the robot and make a second pass to brush and rinse the modules.

Paint Removal Agent

Paint Removal Agent is a cleaning agent especially developed for the removal of interior paints, exterior coatings, multi-surface enamels, and water-based spray paints from the surface of solar module glass.

Robot

Spray first:

• dilute the product and spray on the panels with a sprayer making sure to soak the complete surface
• on severe cases, brush the modules without adding water to make sure that the product can reach the glass
• wait 10 to 20 min
• pass the robot to brush and rinse the modules
• if necessary, repeat the steps above

Mixed in the cleaning water: in severe cases:

• mix the product directly into the cleaning water (directly in the water tank or using a dosing pump)
• brush the entire surface with the diluted product
• wait 10 to 20 min

• if necessary, repeat the steps above

• mix the product directly into the cleaning water (directly in the water tank or using a dosing pump)
• spray the diluted product on the entire surface
• wait 10 to 20 min
• remove the sprayer and install the brush
• pass the robot to brush and rinse the modules
• if necessary, repeat the steps above

Water Softening Agent

The Water Softening Agent is a specially formulated solution that softens hard and very hard water and prevents mineral buildup, allowing your panels to operate at their maximum capacity. It has an action time of about 20 minutes.

Any cleaning method

• Dilute the product, at the recommended dilution for your case, directly in the water tank or deposit. The longer the product is mixed, the better results will provide.
• WSA is compatible with all other Chemitek products.

Antistatic Solar Armor

Antistatic Solar Armor is a specially designed antistatic coating for solar panels that provides a durable and effective barrier against these contaminants, enhancing their efficiency by up to 5%.

WFP, rotative brush, robot, or brush on tractor

• Dilute the product directly in the cleaning water tank or mix it in real time with a dosing pump.
• Clean the modules as you would if using just water. The mechanical action of the bristles against the module will promote the adhesion of the coating while you are cleaning. After cleaning, you don’t need to rinse the modules.

Note: This product is not recommended to be applied with manual brush. To have the antistatic protection on the modules, using a manual brush, we recommend the Solar Wash Protect (SWP).

 D-Solar Defendor

D-Solar Defendor (DSD) is a high-performance coating designed specifically for solar panels. It combines the hydrophobic properties with the antistatic properties, reducing dust adhesion to the modules, keeping your solar panels cleaner between cleanings.

WFP, rotative brush, robot or brush on tractor

• Dilute the product directly in the cleaning water tank or mix it in real time with a dosing pump.
• Clean the modules as you would if using just water. The mechanical action of the bristles against the module will promote the adhesion of the coating while you are cleaning. After cleaning, you don’t need to rinse the modules.

Note: We don’t recommend that you apply this solution with manual brush.
