Hi all, 

My partner and I are starting our circumnavigation on a Hanse445 (2012) next spring. Obviously there is quite a lot of upgrades that needs to be done with the power set up being one of the key points. We have covered the deck forward of the cockpit with flexible solar panels which gives us around 500W. However, I was wondering if anyone has set up solar panels on the pushpit and in that case how large was your panels? The pushpit on Hanse is generally small so if anyone has any pictures on how they did it that would be awesome. My feeling is that they might be in the way when docking and in Marinas, but we will still spend the majority of our time at anchor. 

I would also be curious to see if anyone has installed a wind generator and how this looks. And if anyone has any insight on how large the battery bank should be I appreciate all suggestions or knowledge from other Hanse full time cruisers. 

Thanks and all the best, 
Axel

I have 400W flexible solar but thinking of adding an arch with another 400W (2 200W panels 1500 x 685mm).  This would go above and behind my Bimini.
I have 3 x 160Ah batteries, no generator and only 500W inverter.
Live-aboard during summer months, mostly at anchor.
Not keen on a wind generator which probably wouldn't be much good in the Med with very variable winds.

We liveaboard with 2x 300W flexibles in front of sprayhood each with own MPPT to reduce imopact of shading, Rutland 1200 wind generator, 600Ah Lithium, Victron Multiplus 3000, Fischer Panda 5000i generator and Desalator D60 watermaker.

This summer we cruised west coast of Ireland. ~51-55 North

All our cooking is either induction, microwave or Ninja pot; we have no gas. Pretty much all our water has been desalinated. We have a pretty power-hungry boat!

Wind generator cannot be relied upon; often goes weeks generating noting at all. Solar has generated half expected amount even compensating for northerly latitude and panels being flat rather than angled at optimal elevation. Put this down to shading either from mast/boom or sprayhood. Often see 20A plus from two panels; rarely more than 25A.

Generator has been running typically 11-hours a week which is far too much. We have 120A charger in Mulktiplus and an additional 100A charger so generator runs at its maximum 3.5kW. We usually only run watermaker when generator runs however it will run on just inverter with at ~50A DC.

In more southerly climate and on less power hungry boat, 600W of solar may be enough but for us, we definitely need more solar. Been resisting a big ugly solar arch ... but this may be the only solution to reduce generator run hours.

Hope that helps.

Many thanks for the input. Useful for planning the amount of solar to put in. We are looking at around 600W when we are done and then if we need more I think an arch is the way to go.
