Got solar panels on your home or business? Keeping them clean is necessary if you want to get efficient conversions of solar to electricity or even to heat water. Some roofs are less that congenial palce for a person with a sponge mop. I recently heard a biologist tell about cleaning gull poop off the solar panels that power the buildings and lighthouse on the Farallon Islands, 25 miles from San Francisco. He'd want to know about this start-up.
OCS Energy's SolarWash is based on automation. No cost-intensive labor, no climbing on steeply sloped roofs. Essentially it uses a system similar to the ones that are used to keep a car windshield clear. Check out the OCS website, they have a YouTube video of the wash system in operation.
