Clean Solar Panels Can Achieve Up To 30% More Energy Efficiency


At their 1.6 million-watt solar farm in Mountain View, CA, Google conducted a groundbreaking experiment. They discovered that “the number one method to maximize energy produced by solar panels is to clean them.” They found that “cleaning solar panels that had been in operation for 15 months doubled their output (of electricity)”. They also reported that “professional cleaning of solar panels produced 12% higher output compared to those cleaned by rain.”

Here at DAPrDAN, we’re fanatical about doing things the right way. Not only will we clean your solar panels with deionized water for a spot-free shine, but we’ll apply a protective solution to your solar panels that will help to prevent premature soiling and stains. Depending on the level of service you choose (and your panels), we’ll treat the roof surface under your panels for moss, algae, lichen, mold, mildew and harmful bacteria.


What your neighbor in Mill Creek, WA says:

A positive recommendation here for DAPrDAN home services. Meeting with Greg first to discuss all things we were looking to have done. Very professional and knowledgeable about products they use and services were scheduled soon after first contact. All services were completed in a timely manner and I was very happy with end results. The two technicians were delightful, took their work seriously and yet seemed to enjoy the tasks they performed. When work was completed we did a walk around outside and I was able to see all they had done. Outstanding.
