Hello DIYers,
I currently spray, or rather stream, RO water on 54 roof-mounted solar panels with a conventional 2.5 gallon deck sprayer to remove accumulations of dust particulates, pollen, and bird-crap.
This is followed by a squeegee routine.
It requires about 10 gallons of water that I have to carry up the ladder and a lot of hand pumping topside.
Has anyone used a scuba tank to pressurize a ground-based water tank to lift water 20 feet and deliver 50 psi of water pressure on top ?
I wash just before sunrise before panel temperatures rise too far above the water temperature of my water supply that is stored outside to avoid shocking and possibly cracking the glass.
The noise of a compressor pump at that time of day would annoy my neighbors.
High water pressure greater than 50 psi is not as crucial as water volume, with 20 gallons as a target.
Hose length would need to be about 75 feet and the rise is about 20 feet.
I couldn't ask Archimedes to help, but did notice a thread here on pneumatic power tools that began to answer the question.
Anyone encounter this problem before, or have any thoughts ?
