CleenU product solution
Solar Panel Cleaner
pH-neutral, residue-free · Coating-safe · Private label
Dust and bird droppings quietly dragging solar output down? Early or late when panels are cool, dilute 1:50, wash with a soft brush, rinse, and let them air-dry, safe on glass and anti-reflective coatings. Factory-direct private label.
- Dust, droppings, and pollen block light, and hard-water rinsing leaves spots. In rainy, low-dust areas rain may be enough; in dry, dusty places, near farms or construction, or where birds gather, dirt blocks enough light that regular cleaning pays off. This neutral cleaner loosens the grime with mild surfactants and a chelator prevents residue, so a soft brush and a rinse do the job.
- Panels run hot at midday, and cold water can cause thermal stress while the cleaner dries too fast and spots. Clean early or late when panels are cool, using a soft brush or extension pole, never pressure washers, stiff brushes, or abrasives. Use proper roof safety, or hire a professional.

Before & after

- Before: yellow dust and droppings
- Evening wash at 1:50, soft brush, rinse
- Clear glass, no spots

How it works
How panel grime comes off safely
Panel soil is mineral dust, pollen, organic matter from droppings, and dried hard-water residue. Mild nonionic surfactants wet and suspend dust and emulsify organic soil, the neutral pH leaves anti-reflective coatings alone, a chelator binds calcium and magnesium so rinsing leaves no white spots, and a soft brush avoids scratches.
- Early or late, panels cool
- Dilute 1:50
- Wash with a soft brush
- Chelator prevents spots
- Rinse and air-dry

Usage guidance

Frequently asked questions (FAQ)
Find practical answers about Solar Panel Cleaner, private label, samples, MOQ, documents, and delivery.
Product, use, and procurement
Do solar panels need cleaning?
In rainy, low-dust areas rain may be enough. In dry, dusty places, near farms or construction, or where birds gather, dirt blocks enough light that regular cleaning pays off.
Why not use a regular cleaner?
Many cleaners are alkaline or abrasive and can harm anti-reflective coatings, and residue attracts dust. A neutral, residue-free formula is the better fit.
How fast can we get samples and a first order?
Free samples ship in 3–5 days. MOQ is 500 bottles, and production is scheduled once packaging and labels are approved.
Product usage questions
How do I use it?
Early morning or evening when panels are cool, dilute 1:50, wash with a soft brush or extension pole, rinse, and let them air-dry.
When shouldn't I use it?
Don't clean hot panels at midday, skip pressure washers, stiff brushes, and abrasives, and use proper roof safety or a professional.
How often should panels be cleaned?
Every one to three months in dry, dusty areas, once or twice a year in rainy ones, and whenever droppings appear where birds gather.
Is plain water enough?
For light dust, yes; droppings and oily grime need a cleaner.
Can I use it on glass canopies and sunrooms?
Yes, at 1:50 with a soft brush.
Will it affect my panel warranty?
Neutral cleaner, a soft brush, and avoiding heat match common manufacturer guidance; check your panel maker's instructions.
What about hardened bird droppings?
Spray, let them soften a few minutes, then brush off with a soft brush.
Will tap water leave spots?
Hard water can; a final rinse with purified or soft water works better.
Can I use it on RV and car-roof panels?
Yes, the same way; take care working up high.
Should I shut off the system before cleaning?
Follow the system's instructions and keep away from junction boxes and connectors.
Does cleaning solar panels improve production?
It helps most where panels actually get dirty. In dry, dusty areas, near farms or construction, or where birds gather, grime and droppings block light from reaching the cells, so cleaning recovers what the dirt was blocking. In rainy, low-dust areas, rain often keeps panels clean enough; compare your monitoring app before and after a wash to see whether it pays off.
Can I clean solar panels myself?
Yes, if you can reach them from the ground or another safe spot. Work early or late when the panels are cool, dilute 1:50, wash with a soft brush or extension pole, and rinse. Leave roof arrays you can't reach safely to a professional, and keep water away from junction boxes and connectors.
How do I clean a portable solar panel?
Wipe it instead of hosing it. Dilute 1:50, wipe the face with a soft cloth or brush, let bird droppings soften a few minutes first, then wipe with a clean damp cloth and let it air-dry. Keep liquid away from the cable and connectors.
OEM/ODM customization questions
What can we customize?
Formula direction, scent, pack size and format, label design and language, and ecommerce bundles.
What paperwork comes with a private-label order?
Documents such as SDS/MSDS, TDS, COA, and label copy for your target market are prepared per project. We confirm which ones your order includes when we quote.
