cleaning solar panels

accumulated dirt. How often (if at all :)) do you clean the solar
panels and with what? I have the AstroPower 110 Watt panels.

However if the panels are in a particularly dirty environment, ie very
dusty conditions, or near your wood stoves' chimney, you may need to wash
them regularly.
Use warm water and mild detergent (dish soap).

I clean mine once a year, and use a silicon based wax on them... works
for me, and seems to help keep ice accumilation down as well.

The silicon wax is a car wax, but it is one of those once a year waxes,
another good one is a teflon based auto wax.
I would not however use any wax designed for showers or shower doors, as
they are not stablized for UV and weather as car waxes are.

I guess if the refractive index of the film is below 1.5 ( about glass) you would get a disposiable AR coating of sorts.

I wondered about that as well, but could see utterly no loss in wattage
generated after application of the wax. Actually if anything else it is
the reverse because the glass stays cleaner for longer periods of time AND
the glass cleans itself pretty well during rainstorms, so that wattage is
actually a little higher on the average due to the PVs remaining cleaner
of dust and such.
