Can I spray water on solar panels?

Answer #1: Yes, and You Can Do It Yourself – Bird droppings and other dirt agents can affect your solar panel’s performance, especially if your panels lie truly horizontal on the roof. That’s where washing the panels becomes important, though it doesn’t have to be a thorough or routine cleaning in many cases.

As we suggested to the customer with the white powder on their panels, cleaning your solar panels is usually a relatively easy task. All you need to do is to spray the panels with average-pressure water from a well-angled garden hose while standing on the ground. If you want extra cleaning power, a long-handled squeegee or soft brush plus a medium-pressure hose nozzle can work wonders.

With the nozzle, directing the spray will become easier. You’ll then wipe off the water using the squeegee for maximum electricity production. This approach provides even more cleaning power, but it does depend on the angle of your roof, roof height, and panel placement, because not everyone will be able to reach their roof, even with a long handle.

Is rain enough to clean solar panels?

Should I Clean my Solar Panels? – While dust and dirt settling on your panels is unavoidable, thankfully, so is rain. Even just a mild and short rain shower will do a sufficient job of cleaning the grime off your panels and will have them performing at their full potential with no effort or money spent. In order for the rain to properly clean your system, the panels need to be pitched. The good news is, the study showed a pitch as slight as 5 degrees did the trick. So as long as your solar panels don’t sit completely flat, rain will be enough to get your panels clean.

The Type of Dirt Another consideration is the dirt itself – what is making the panels dirty and how often does it accumulate? While normal airborne particles such as pollen, dirt, and dust will wash off in the rain with ease, there are some items that could be a bit trickier, like bird droppings. Keep an eye on your panels before and after it rains to see if they’re coming clean.

If some stubborn dirt is still hanging around, it may be worth looking into having them cleaned. The System’s Location Another item that could factor into whether or not you should clean your solar panels is the system’s location.

Can you clean solar panels with tap water?

How to Clean Your Solar Panels Solar panels can sometimes accumulate dirt, dust, and ash in summer in Southern Oregon.

  • However, summers of smoke and ash or heavy soiling due to dust or bird droppings can affect the production of your array and you may find it necessary to clean the solar panels more often.
  • For your safety, we strongly recommend hiring a local window washing company.
  • If you do it yourself, please stay on the ground.

Never get up on your roof without a secure ladder and proper fall-protection equipment. Recommendations:

  1. Turn off your system before cleaning.
    • Consult your True South Solar manual to see how to turn off your system to protect it. If you are unsure, please call our office at 800-947-1187.
  2. Clean early in the morning or in the evening when the panels are cool.
    • During the heat of the day, water and soap can evaporate quickly, which risks smearing the soap and dirt.
  3. Use a soft-bristle brush with an extended handle, soft sponge/seamless cloth or soft squeegee.
    • DO NOT use abrasive brushes, pads or powders.
    • Use of such abrasive materials will void the product warranty.
  4. Use non-heated, potable water with normal water pressure, over-the-counter glass cleaner (such as Windex or equivalent) OR a 3% soap-and-water solution.
    • Pressurized water up to 1,500 psi may be used when necessary.
    • AVOID harsh industrial strength cleaning products
    • AVOID hard, or mineral-rich, water. It can damage panels over time. If your area only has hard tap water, you can buy an inexpensive water-softening hose attachment to filter out minerals. Otherwise, you can use distilled or de-ionized water.
