New 348 owner, weighing the alternatives of a methane cartridge fuel cell versus installing solar panels. I've had solar on prior boats with limited success. We cruise in the Salish Sea so outside of summer, weather and daylight are issues. A friend advocated for a fuel cell system, which worked well on his prior larger yacht. Curious if any Hanse owners have gone that route. 

Thanks!
Hugh

Hi Hugh,

I once met a Hanse 445 that had this installed. The owner was very satisfied with it.
Autostarted at low voltage and always kept the batteries charged. 
I would like to have one if they where not so expensive as they are.

Patrick Laine likes his. The only downside I can see is that (like a battery) their efficiency declines over time. It would be worth finding out what their expected useful life is. They are expensive too and Im not sure about the availability of fuel. Probably pretty good as a live aboard but my preference would be a watt n sea hydro generator for extended passages. Amazing piece of kit

I am also in BC. I have 2 100 Watt solar cells on top of the dodger and one 150W on deck over the main hatch box. All wired in parallel, MPPT controller. I alwasy leave the fridge on and from March 15 to October 1 have no need of shore power. The batteries are usually fully charged by noon. On a cloudy or rainy day they still produce some powere, but their is a small deficit.

Once October comes, I plug in the shore power.

Hi, I have an efoy fuel cell on my new boat, unit about the size of an old school computer hard drive, set to kick in automatically when voltage gets to 12.3v. Only really needed after approx 3 days at anchor with no sun or motoring. A 10lt bottle of methanol last a week if running daily or 3 months as back-up to solar.

Considering the simplicity and tiny space vs generator i think they are a really good solution.
