What’s the Best Time of Year to Clean Your Solar Panels?

Now that you’ve invested in solar panels, you’re reaping the benefits of clean energy – including lowered energy bills! However, in order to keep your panels as efficient as possible, it’s important to keep them clean. Below, you can learn more about the best time of year to have your solar panels professionally cleaned so that you can continue to enjoy all the clean energy your home or business needs. 

How Often Should Solar Panels Be Cleaned?

This is a common question, but there’s no one right or wrong answer. In fact, it depends on numerous factors such as the weather, the number and type of trees in your area, and even the direction of the wind. For example, your neighbor down the street may only need to clean her solar panels twice every year since she doesn’t have pollen- or sap-producing trees in her yard. On the other hand, you may need to have yours cleaned up to four times a year – especially if there are trees dropping pollen, sap, and other debris down onto your panels. 

When is the Best Time of Year to Clean Solar Panels?

While this, too, can vary a great deal based on the climate, in New Hampshire, the best time of year for solar panel cleaning is late spring. This way, the professionals can remove all of the pollen that has accumulated on the panels’ surface so they can absorb more of the bright summer sun. The second cleaning of the year should come in late fall – after most of the leaves have fallen from the trees. This way, there’s as little debris as possible and your panels can make the most of the limited winter sunlight. 

What Should I Do Between Cleanings?

In almost every case, it’s best to hire a professional to clean your solar panels at least twice a year. It’s safer for you, and it’s better for the solar panels. In between cleanings, home and business owners generally don’t need to do much. Most of the time, getting out the garden hose and spraying them down gently is all it takes to remove any surface buildup that accumulates between professional cleanings. If you choose to give your panels a deeper clean, make sure that you are using products recommended by the solar panel manufacturer. Harsh chemicals – or even certain milder chemicals – could do more harm than good. 

Pick a Service Plan

The best way to keep your solar panels clean all year long is to hire a professional who can set you up on an annual maintenance plan. These plans generally include anywhere from two to four professional cleanings each year, and if you need cleaning in between, it’s possible to get it at a discounted rate. Remember that these professionals have the right training and equipment to keep your solar panels working as efficiently as possible, so instead of DIYing your solar panel cleaning needs, leave it to the pros. 

If you want to get the most out of your solar panels, you should have them professionally cleaned in late spring and late fall. This way, your panels are primed and ready to make the most out of the sun’s abundant energy – and you can reap all the benefits!
