Solar panels provide a greener way to power your home, and they also help lower your energy costs by up to 20% or more. The key to maintaining their capacity and longevity, is to keep them clean, which professional power washing can help you accomplish.
Solar panels generate power by utilizing sunlight. When light hits the panels, it will convert it into energy that can then be used to provide a low-cost alternative source of electricity, depending on your solar system type, for your home.
Over time, the panels can become riddled with various outdoor elements, such as dust, dirt, pollen, sap, animal droppings, and more. This will essentially coat the panels with grime and prevent sunlight from fully penetrating them, resulting in a loss of energy absorption.
In fact, according to reports, dirty solar panels can decrease energy absorption by up to 10% or more in some cases.
Frequently cleaning your panels provides various benefits. Continue reading to learn more about why maintaining clean solar panels is ideal.
What Are The Benefits of Cleaning Solar Panels?
Why Cleaning Them Regularly is Important
How Often Should I Clean My Solar Panels?
Solar Panel cleaning intervals will mostly depend on the environment.
For instance, panels installed in areas with high dust levels, such as in rural areas, near areas of high traffic, or in areas with lots of air pollution will require more frequent cleanings because they will accumulate dirt faster than panels installed in low dust areas.
This is also true for solar panels installed near the sea because they can collect salt build-up, which can cause erosion.
The angle of your panels can also affect how often they will get dirty. For instance, flat-mounted panels can allow rainwater to pool at the lower edge, which enables debris to gather there. They need to be cleaned more often than vertical panels where most debris is more likely to roll off with the rain.
On average, you should have your panels cleaned at least once every six months to every year to maintain maximum performance.
In the meantime, should you notice a drop in energy output, it could be an indicator that your panels need to be cleaned.
Why Professional Solar Panel Cleaning?
Solar panels contain electrical parts, which can become easily damaged without the proper care when cleaning them, which is why it is usually recommended to have your panels washed by professional cleaners.
It also helps ensure the panels are cleaned as per the manufacturer's directions, which helps keep your warranty valid.
Professional solar panel cleaners also have the right professional tools and pressure washing equipment to safely reach and thoroughly clean the panels, which helps eliminate the danger of doing it yourself.
They can also inspect your panels for cracks and worn seals that can enable water to seep into the panel's inner parts, which can damage them.
If you have found that your solar panels have lost their brilliance, or if your system is experiencing a drop in energy, feel free to schedule an appointment with us to see if dirty panels could be the issue.
