Re: Wind generator
Our wind generator help keep the boat from tacking at anchor. Otherwise I use a riding sail. That's something to consider if you have a reasonably high performance boat.
If it wasn't for that, I'd proably switch to 100% solar. Using the Victron battery monitor, I watch 8 amps go into the batteries all day long from a Kyocera 135 and a Seimans 40. But when the wind is blowing, we get only 4 amps from the wind generator.
If you anchor where it's really windy, get the wind generator. If you anchor where it's really sunny, get solar panels.
Whatever you do, make sure you sit next to it for an hour before you buy one. The little AirX wind generators sound like a Cessna taking off. They are off-the-scale annoying and will make you instantly disliked in the anchorage.
I plan to get 2 more Kocera 135s and mount them above the bimini, just aft of the boom. Being able to see the amps coming in all day long is fantastic and we need to up the ante to run a freezer next summer.
(Don't forget to factor-in the cost of the mounts.)
