SOLARSUDZ
Solar Panel Cleaning Solution

Description

SOLARSUDZ effectively cleans PV panels and maximizes power generation. Its special formulation removes a wide range of contaminants, such as air pollution residue, pollen, bird droppings, dust, and salt deposits.
It is designed with a rinsing aid to eliminate the need for deionized (DI) or reverse osmosis (RO) water.

PRODUCT FEATURES

• Suitable for residential & commercial use.
• Developed & certified especially for photovoltaic solar panels.
• Restore photovoltaic efficiency to maximise panel output.
• Economical: Reduces water use and cleaning costs.
• 100% Biodegradable as SOLARSUDZ is free from ammonia, Butyl Cellosolve, Areosles, & more.

REDUCES WATER USE

SOLARSUDZ is more effective than water alone. As a result, soils are removed more efficiently and less water is used. Field
experience proves this:
SOLARSUDZ was tested in Panama -South America where the existing cleaning procedure used 5 liters of water alone per
panel. Using a 25:1 water-to-SOLARSUDZ mix, only 3 liters were required to clean 10 panels. Water use was reduced by a
factor of 15.
SOLARSUDZ has a spot-free rinse, eliminating the need for deionized water. Elimination of deionized water yields more water
savings, since it takes more than a gallon of water to create one gallon of DI or RO water.
Efficient cleaning saves water and is more environmentally appropriate. It is an effective cleaning method that also saves
labor time.

END USES

• Utility-owned solar farms
• Industrial arrays
• Commercial arrays
• Residential ground and rooftop-mounted panels

WASHING PANELS INCREASES PERFORMANCE

Regular cleaning maximizes PV system performance and longevity. A 2023 World Academy of Science, Engineering and
A technology study concluded that “accumulated dust on the surface of photovoltaic solar panels can reduce the system’s
efficiency by up to 50%.

In an EPRI study, industry stakeholders estimate that “panel washing can improve efficiencies by as much as 10-15%.
Cleaning maximizes return on investment. It is especially effective on flat, low-tilt panels.
Even small areas of contamination can have a significant impact on panel performance. Solar cells connected in series are only
as good as the lowest-performing cell.

Cleaning is also good practice to avoid hot spots.

DIRECTIONS FOR USE

General Maintenance Note:
Inspect the entire solar array system before cleaning to detect loose or broken wires and panels
or improperly functioning apparatus. Make necessary repairs before cleaning. Schedule regular cleaning and maintenance to
keep the system operating at theoretical maximum output.

SOLARSUDZ Usage Recommendation:
Recommended, starting dilution ratio is 1 part SOLARCLEAN to 25 parts water (25:1).
For heavily soiled areas, use a higher concentration.
Always schedule panel cleaning early in the morning or at night when it is cool. This will minimize thermal stress on
photovoltaic cells and protective glass that could damage the panels.

Use SOLARSUDZ solution to rinse panels:
Rinsing removes loose sand and debris from the panels and protects them from scratching when brushes are used in.
It is okay to rinse with local water only.
Wet only the number of panels that can be brushed and rinsed before the SOLARCLEAN solution dries.
Large arrays may need to be cleaned section by section. Use heavier amounts of SOLARCLEAN on areas with bird droppings or
other organic matter.
Scrub panels with a soft brush (hog’s hair or similar). Rinse the brush bristles frequently when cleaning heavily soiled arrays
to reduce scratching. The use of brushes helps agitate the cleaning solution; dirt tends to “carry” or be lifted from the panels
better. Water alone—even deionized water—will not adequately lift dirt.
SOLARSUDZ is far more effective at removing residue and cleaning panels.

Allow the solution to shed from the panel surface:
Repeat steps 1 and 2 for hard-to-remove contamination.
Rinse the panels with SOLARCLEAN solution and let dry; otherwise, rinse with deionised water or local water supply.
If desired, dry the clean panels with a microfiber cloth for a fine finish

ENVIRONMENTAL IMPACT

SOLARSUDZ is readily biodegradable per Guidelines. The resulting products of biodegradation are carbon dioxide and water.
SOLARSUDZ is biodegradable, it therefore does not accumulate in the environment.
SOLARSUDZ is an environmentally safe solution for cleaning solar panels.
