I don't know what all of the contributors are, but in Brisbane, Oz, where out boat is parked many of the houses have between 15 and 30 solar panels on the roof. It is a very good area for solar with intense radiation, and electricity in the country is pricey since they don't have big hydro installs or nukes. I wonder if there are government rebates when you buy the panels or what? I think a fair comparison would be Queensland and Florida and you rarely see so many solar installations in Florida.
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
