Solar panels should be cleaned at least twice a year to maintain optimal performance, though the frequency may vary depending on your location and environmental factors. For example, if your panels are exposed to heavy dust, pollen, bird droppings, or if you live near construction sites, agricultural fields, or areas prone to wildfires, you may need to clean them more frequently—perhaps every three to four months. Regular cleaning ensures that your panels can absorb the maximum amount of sunlight, which directly impacts their energy production and efficiency. At Foothill Solar Panel Cleaning, we can assess your specific situation and recommend a cleaning schedule that best suits your needs.

While it might seem simple to clean solar panels yourself, it's generally recommended to hire a professional service. Solar panels are delicate and can be easily damaged if not cleaned properly. Using the wrong cleaning materials, such as abrasive sponges or high-pressure water, can scratch the surface or damage the panel’s seals, leading to reduced efficiency or even costly repairs. Additionally, cleaning panels on a rooftop can be dangerous without the proper safety equipment and training. At Foothill Solar Panel Cleaning, our technicians are trained to clean panels safely and effectively, using eco-friendly products and techniques that protect your investment and ensure optimal performance.

The cost of solar panel cleaning varies depending on factors such as the size of your solar array, the level of dirt and debris, and the specific services required. On average, you can expect to pay anywhere from $100 to $300 for a typical residential cleaning, with commercial projects varying based on the scale. While there is a cost associated with professional cleaning, it is a worthwhile investment. Dirty panels can lose up to 20% of their efficiency, leading to lower energy production and higher electricity bills. Regular cleaning helps ensure that your panels are operating at peak efficiency, maximizing your energy savings and extending the life of your system. At Foothill Solar Panel Cleaning, we offer competitive pricing and maintenance plans to keep your system running efficiently without breaking the bank.

Keeping your solar panels clean has several significant environmental benefits. Clean panels operate at peak efficiency, which means they can generate more electricity from the same amount of sunlight. This increased efficiency reduces the need for additional power from non-renewable energy sources, which often rely on fossil fuels that contribute to air pollution and greenhouse gas emissions. By ensuring your solar panels are clean and performing optimally, you maximize your contribution to a greener, more sustainable energy grid. Additionally, regular cleaning prevents the buildup of harmful substances like bird droppings and mold, which can damage the panels over time, potentially leading to premature replacements and the associated environmental impact of producing and transporting new panels. At Foothill Solar Panel Cleaning, we use eco-friendly cleaning solutions, further minimizing the environmental footprint of maintaining your solar system.
