Never got the water fed pole, good thing as it would get used 1 time a year. I am giving a bid on the house pool cage, deck, and floor of garage. When I looked for up sells I saw the solar pannels and they are in need of cleaning. My only source of water is well water and I would rather not use that water on the panels, question is can I just use distilled water with a surfactant, with a mop and pull with a squeegee? Hate to leave money on the table and I have to sets of these on ground level. Pic is to but there is 88 pannels. Thanks.
