get a generator, spare fuel, extra air filters for the genny,
solar is going to get so dusty on the Playa as to be almost un-useable
mount them so they can tilt at the sun, some of the dust will fall off,
wash them every morning, to get maximum yield
maybe use LED rope/strip lighting for area lighting, instead of spots
the illumination will be more spread out for the watts used
from what i have read the playa is a good place for wind turbin power, but investigate, some wind forums, or burning man blogs, to find something that works
skip the flashy websites adv wind power
