Why is it important to clean my solar panels and how often should I clean them?
When your panels are dirty, your power generation is greatly reduced. When dirt builds up, your panels quickly become shaded by a layer baked on by sunlight. Even heavy rain won’t take this off. The shading reduces energy generation by 20-30%, thus reducing the ROI of your solar installation.
​
The National Renewable Energy Laboratory recommends cleaning solar arrays at least once per year. However, you may benefit from cleaning your solar panel more often depending on weather, humidity, vegetation, proximity to urban areas or to the seaside, angle of your panels, etc.An annual clean-up has been found to improve energy output by as much as 12% when compared to panels that were only cleaned by rainfall.
What types of solar installations can Pack Solar handle? Will the cleaning robot damage my panels?
Our robot can clean virtually all types of solar commercial and utility scale installations (on ground, rooftop, carports, or floating) with a pitch of up to 25º (up to 45º with a safety glider).
​
No. Solar panels are generally designed to accept a load of up to 0.78 psi (5400 Pa.). Our robots exert a maximum 0.60 psi (4200 Pa.) which is well within safety limits. Separately, the robot's rubber pads mounted on the traction tracks allow movement without vibration and without scratches on the panels.
Why should I choose Pack Solar to clean my panels?
Pack Solar brings everything needed to perform an efficient cleaning job, including hoses and a water pump. If needed, Pack Solar can provide water trucking as well. There is no need for electricity or any other utility as our robots are battery powered.
​
Pack Solar averages over 1MW of cleaning per day and can clean up to 2MW per day depending on the installation.
​
The depth, consistency, and efficiency of our robotic cleaning maximizes solar power generation and increases the lifespan of your panels. Our technology, professional service, and focus on safety sets us apart.
