Pressure washer for cleaning solar panels

An electric pressure washer would be nice but not realistic. My electric pressure washer with a triplex clone pump and 56c frame is only good for about 2.2gpm at 1,500psI with a typical spray nozzle. That's tiny.
By comparison my much more powerful gasoline pressure washer has a 7hp motor and makes 2.5gpm at up to 2,500 psi, that's ok for solar panel cleaning but still slow.
Clearing solar panels with a pressure washer is kind of like cleaning a parking lot. You want to put down as much raw water power out of that nozzle as possible.
So I got a new 4gpm up to 4,000 psi triplex pump for my honda gx390 for $250 shipped out the door. I'll likey run it about 4gpm at 3,000psi depending in the nozzle because the honda gx390 is only going to make about 12hp here in this thin air. And 4@4,000 would take around 15hp. A 16hp V-twin would handle it.
I think a 390cc engine pushing 4gpm at over 3,000psi should be sufficient to clean some solar panels.

Why now? Because no one is thinking about pressure washers during the winter. So I figured I would get on ebay and make am offer.

Why not a Rainbird with soap injection?

The nice thing about those higher pressure washers is that they can drive a sand blasting attachment. I would think that would keep the dust down. OTOH:

en.wikipedia.org/wiki/Dry-ice_blasting
Quote:
Dry-ice blasting is a form of carbon dioxide cleaning, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it.

Compared to other media blasting methods, dry-ice blasting does not create secondary waste or chemical residues as dry ice sublimates, or converts back to a gaseous state, when it hits the surface that is being cleaned. Dry-ice blasting does not require clean-up of a blasting medium.[2] The waste products, which includes just the dislodged media, can be swept up, vacuumed or washed away depending on the containment.

I cleaned my solar panels again with the 7hp pressure washer. Finished off last year's chainsaw 2-stroke gas mix.
It's just slow.
My current 7hp pressure washer runs a sand blaster great, as long as it's above freezing.
