Maintenance and Cleaning of your solar panels are a vital part in their performance.
The season is changing, days are getting longer and the weather’s getting warmer. And we all know what the Spring brings along as well.. The dreaded Spring Cleaning in and around the house…
Now if you have a solar panel on your roof (or in the process of getting solar panels) you have to remember that your panels need a little cleaning and maintenance as well. Luckily for you, solar panels do not have any moving parts which is why there is not a whole lot of maintenance to take care of. However, cleaning is one aspect you should not take lightly.
Well over time dust, dirt, pollen, bird droppings and other debris on your panel can negatively affect your solar panel efficiency. Don’t just take our word for it; a research team from Google found that the number one way to maximize the energy production of solar panels was by cleaning them. The same study showed that rain is not a satisfying way of cleaning solar panels and you can lose 15-25% off your electricity production if not cleaned properly.
Cleaning solar panels is not really that much different than cleaning a typical window. Bonus is that it is not time consuming either! However take great care when following our 3 steps on how to clean solar panels.
1. Check Your ‘Label’
The first thing you want to do is check if your solar panels have any special recommendations for cleaning. Call your solar installer and find out what the recommendations are and comply with the do’s and don’ts.
2. Time Your Cleaning
Keep in mind that solar panels can get extremely hot with the sunlight not even talking about your roof. Therefore choose a time of day that is not too hot to clean your panels, early mornings or late afternoons are recommended.
3. Rinse, Wash, Rinse, Repeat
Rinse your solar panel with water to get off all excess dirt. Try rinsing with a garden hose as the supply of water will be constant instead of using a water bucket. If a lot of dirt and dust has accumulated you might need to clean more thoroughly.
Use a bucket or spray bottle with warm soapy water and a soft cloth or sponge to wash the panel lightly. Don’t press down too hard on your panel. For harder stays soak the stain with the soapy mixture for a few minutes then wash again.
Repeat the process until all the dirt has been cleaned.
In most areas, there is more pollution during the winter months, which is why spring is the perfect time for an annual clean. However, if you can see that the panels are dirty you can clean them as many times as you wish.
The best advice we can give is to monitor changes in the power output of your solar panels before and after cleaning. Experiment with the intervals in which you clean the panels and see what works best for your household.
Now you can clean your solar panels for optimal power output, and while you’re at it clean the gutters, roof and spring clean your house inside out.
