Low voltage at campgrounds? I found the solution.

The need for extra power for air conditioning on sunny days suggests it is a good fit for solar energy. Anyone know of a campground that uses solar for its electricity?

Solar is great for individual off grid or RV applications, but isn't generally practical / cost-effective for commercial use without goobermint subsidies. Thus the reason you don't see campgrounds with space devoted to solar farms, and probably won't.
