Very carefully given that you have to get up on the rooftop and there is glass and electrical wiring involved! After inspecting the panels to ensure there were no cracks or loose wiring, CCSF students Ivan Hu and Toby Taylor
climbed onto the roof and washed and dried the 24 pv panels. Using a soft cloth scrubber and water with a little vinegar and biodegradable dish soap added, Ivan and Toby scrubbed the dirt and bird poop that accumulated on the panels since the summer. Keeping the panels clean is important so that they do not lose efficiency and produce as much electricity as possible. Ivan and Toby will be writing up a standard operating procedure and will make "how to" videos so that future students working at the EcoCenter can follow in their footsteps.
