Solar panels are a great way to save on your energy costs, but they require some regular maintenance in order to keep them running at peak efficiency. One task that often gets overlooked is cleaning the solar panels. In this blog post, we'll discuss how you can safely clean your solar panels and what to do if they get dirty.

Can you pressure wash solar panels

The answer is no. Pressure washing your solar panels can cause damage to them and even void the warranty on your system. Pressure washers use extremely high levels of water pressure (up to 3000 psi) that can cause the protective coating to come off, scratch the panel’s delicate surface, or even break it.

Instead of using a pressure washer, it is best to use soft cloths, sponges, or a garden hose with a sprayer attachment. To do this properly you need to start at the top and move downwards in one direction as you clean each panel. This will help prevent streaking and ensure all dirt is removed from the entire panel.

What is the best time to clean solar panels?

The best time to clean your installation is early morning, late afternoon or on overcast days. Cleaning panels during these times helps reduce the risk of water spots and warping from sun exposure. It also allows for a thorough clean without having to worry about hot temperatures that would affect your cleaning methods. Additionally, be sure to always use distilled water for rinsing the panel surfaces and soft cloths or sponges for scrubbing away debris. Never use harsh abrasives, solvents or corrosive chemicals as this could damage the surface of the panels. Cleaning your solar installation regularly is important in order to ensure optimum efficiency so make sure you take time to keep it maintained throughout the year.

Benefits of cleaning solar panels: Why should you do it?

There are several benefits to cleaning solar panels, including increased efficiency and longevity of the system. It is estimated that a clean solar panel can increase its energy efficiency by up to 15%.

This means that you will be able to generate more electricity from the same amount of sunlight, resulting in lower bills.

Additionally, regularly cleaning your panels can help them last longer and reduce the risk of corrosion or damage caused by exposure to dirt and debris.

Cleaning can also help keep your system running optimally during hot summer months when temperatures are higher and production may decrease due to soiling.

Overall, regular cleaning makes sense for both financial reasons and environmental reasons as it ensures efficient operation of your solar installation over time.

Cleaning your solar panels doesn’t have to be a difficult task. In fact, most solar panel cleaning can easily be done with an adjustable garden hose or a pressure washer.

Be sure to avoid high-pressure water jets as this could damage the glass of your panels and reduce their efficiency.

To ensure that you are getting the most out of your solar system, it is important to keep them clean from dirt, debris, bird droppings and other pollutants.

Having well-maintained solar panels not only keeps your energy bills low but also contributes to a clean and green environment by promoting renewable energy sources.
