Houseboat, perfect! Yes, you need battery power overnight when UNDERWAY, but no more. Because when the sun comes up, you have all the power you need.
Now, what most "wanna-go-off-grid" people overlook is that when the sun is shinning and you are not using the boat underway, then your batteries are fully charged and from that point on, y our investment in solar is doing you nothing. Every day, once your batteries are full, there is n o place to put the excess power. That's where grid tie is a hands down winner. It lets you bank all your excess power at full retail rates... and it helps your fellow man as well as yourself by reducing your carbon footprint.... I'm putting a 3 kW array on a floating deck and two $100 deep cycle marine batteries and 2 trolling motors.. The batteries will make it a boat so I can register it and make it legal. The fact that the other 99.9% of the time it is feeding my house is gravy. And because it is a boat, it does not violate the rules for piers) and lets me DOUBLE the size of my array on the water).. (the only place I have sun.).. See: http://aprs.org/alternative-energy.html about 40% down the page... Same goes for RV's that just sit by the house 99% of the time. Cover them with solar panels for when you are remote-wilderness camping, but all the rest of the time, let them bacfeed your grid so that you are getting return on their investment everyday, every photon,... But without grid tie, and net metering, you cannot do anything to your advantage with all that solar power. except the 1% of the time you actually use the RV or boat. A terrible return on investment.
