5 Benefits of Automatic Solar Panel Cleaning

Solar is a great investment – that’s a fact. But without proper solar panel maintenance, your investment is not protected like it should be. Cleaning your solar panels regularly is one of the best ways to protect your panels and your investment. However, many homeowners and business owners with solar panels are not familiar with solar panel cleaning best practices and might even employ techniques that jeopardize panel warranties. This is where RST CleanTech comes in.

What is Automated Solar Cleaning?

Automated solar cleaning systems like RST NightWash™ keep your panels clean at all times with regularly scheduled cleanings. Unlike traditional solar panel cleaning that entails manual workers coming to your property to clean your panels, RST NightWash™requires no human labor after installation. You don’t even have to worry about remembering to schedule the cleanings because it is – you guessed it – automated.

Top 5 Benefits of Automatic Solar Panel Cleaning 

1. Increased Energy Production

When people think of solar panels, they often think of the money we save from using the sun as a renewable energy source, in addition to reducing greenhouse gasses into the environment. Most of us don’t realize that our solar panels can’t reach their full energy production potential if they’re dirty. An automated solar panel cleaning system protects your investment by keeping the solar panels clean all the time, which can lead to an increased production of up to 30 percent more energy.

2. Minimal Maintenance

Once the RST NightWash™ automated solar cleaning system is installed on a home or commercial property, there is no additional labor required. Our systems are custom made to fit the exact needs of a given residential or commercial solar array and accommodate changing seasons. 

Plus, there are no moving parts, which makes it easy for homeowners and business owners to enjoy the benefits of constantly clean panels without the worry of needing to repair or replace parts of the system.

3. Protect Panel Warranty

Unfortunately, some traditional solar panel cleaning methods can do more harm than good. While keeping solar panels clean is extremely important to maximize production, doing it incorrectly can cost you in the form of damaged panels and voided warranties. On the other hand, RST NightWash™ is designed in compliance with all solar panel manufacturer standards and requirements. Our system cleans at night to avoid thermal stress and it uses soft, purified water in order to eliminate limescale buildup. 

4.  No Personal Injury Risk

Climbing up and working on roofs can be dangerous for people and panels alike. An automatic solar panel cleaning system like RST NightWash™ eliminates the need for cleaners to physically get on the roof of your home or commercial building. This significantly reduces your liability as a property owner. 

5. Completely Green

RST NightWash™ is a solar panel automation system that is completely green. We don’t use any chemicals or their byproducts – just soft, filtered water. It’s also extremely efficient with water usage to avoid any unnecessary waste.

The Right Way to Clean Solar Panels

Manually cleaning your solar panels will increase production temporarily, but the panels will get dirty again in a few weeks. RST CleanTech’s fully automated solution will continuously keep panels clean in the safest and most efficient way, with no risk of voiding your warranty.
