How much does it cost to get solar panels cleaned?

Solar panels are an excellent investment for anyone looking to harness clean, renewable energy. However, like any other equipment, solar panels require regular maintenance to function at their optimal capacity. One common maintenance task that you may be wondering about is cleaning. Cleaning solar panels not only improves their efficiency but also prolongs their lifespan. So, how much does it cost to get solar panels cleaned? Let’s explore the factors that influence the cost and see what options are available.

The cost of professional solar panel cleaning

**To get solar panels professionally cleaned, you can expect to pay an average price of $15-$35 per panel.** The overall cost will depend on several factors, including the size of your solar panel system, the number of panels, the complexity of the installation, accessibility, and the cleaning method used by the professional.

If you have a smaller system with only a few panels, the cost will likely be on the lower end of the spectrum. However, for larger installations or for panels that are difficult to reach, the price may increase. Some companies charge a flat fee for the entire cleaning job instead of charging per panel. It’s advisable to get quotes from multiple companies to find the best deal.

The DIY approach

**If you choose to clean your solar panels yourself, the cost can be significantly lower.** All you need is some basic cleaning equipment such as a hose, soft brush, and a non-abrasive cleaner. In most cases, warm soapy water is sufficient to remove dirt and debris from the surface of the panels. However, it’s important to note that you should follow the manufacturer’s guidelines and avoid using abrasive materials or harsh chemicals, as they can damage the panels. Additionally, ensure your safety while working at heights if your panels are installed on the roof.

While cleaning solar panels yourself may save you money, it’s essential to consider the risks involved. Without proper knowledge and equipment, there is a possibility of accidental damage, which could lead to costly repairs. If you are unsure or uncomfortable with cleaning the panels yourself, it’s best to hire a professional.
