Solar panels are very low maintenance, especially in the Midwest. Panels are regularly and naturally cleaned with normal precipitation in our region. Similarly, solar panels are tested to withstand extreme weather like large hail, high winds, heavy snow, or thick ice.
Some Common Forms of Panel Soiling in the Midwest
- Fallen leaves & sticks
- Dust
- Pollen
- Grain dust
- Bird droppings
- Heavy snow & ice
When Stateline Solar designs your system, we calculate these typical soiling averages to ensure your production estimation is accurate. Cleaning your panels is not essential to production, unless there is a large and obvious obstruction. In most cases, regular precipitation can correct these soiling issues.
This is a example calculation created in our solar design system. Customers can be confident in the accuracy of their system size and estimated production once all of these important factors are calculated by our Solar Designers.
Cleaning Your Solar Panels
Solar panels can be cleaned with a regular garden hose or light brushing with a broom. It is not necessary to turn off your system for gentle cleaning.
Tips:
- Clean your panels during overcast days, early mornings, or evenings to prevent rapid water evaporation that might smear dirt and grime
- Brush off debris and dust with a soft broom before washing panels
- If you have mineral-rich hard water, squeegee water off the panels. Mineral build-up from hard water can add additional soiling
- Oily stains can be removed with a cloth and isopropyl alcohol
Avoid:
- Climbing on your roof to reach panels that are only accessible with a ladder
- Metal objects or abrasive products that may scratch panel glass and cause damage
- Power washing
Monitoring your system regularly can help you identify significant soiling issues. Most solar owners allow Midwestern weather to take its course and naturally clean their panels. If you have concerns or see dangerous obstructions, please contact Stateline Solar.
