I will be installing a small solar panel in front of the spray hood in the next few weeks. Before I start pulling the boat apart has anyone found a cable route from the void where the sliding hatch goes (just in front of the spray hood) into the the saloon and down to the electrical panel or battery compartment.?
An initial inspection finds no obvious path.

It might not be the same on your boat, but on the 385 we went above the head lining to the mast post, drilled a hole in it, down inside the mast post, drilled a hole below the saloon floor, then ran the cable below the floor using existing wire and pipe ways into the battery box and then to our regulator which is behind the cushions with our battery charger.

Be aware that a flat solar panel is not that good. I would have two panels beside each other and a little tilted. One for port and one for starboard. And two regulators.

Our one flat 70W 'solara' panel is there to avoid having to use shore power when the boat is left alone rather than any attempt to provide power whilst cruising. even so it regularly gives me a couple of amps in the day, and coupled with our aquair 100 hoistable/towable generator limits the amount of engine charge we have to do.  As we dont have any davits or binimi, and sail with the spray hood down, we dont really have anywhere else to put much more solar.

Thanks 
Had a look at the post and like the ideas.  My panel on the coach roof is not really intended to supply cruising needs.  This is more to keep the batteries topped up when I am away from the boat so not that bothered about absolute efficiency.

hi,
how did you manage to do that? how did you route the cable and remove  the ceiling padding ?
thanks for an exaustive explanation or pictures if you can.

we are not on the boat at the moment so I cant take photos.  however, we drilled a little hole in front of the hatch cover and fed the cable through it.



we removed one of our lights from the ceiling, and using a bent coat hanger fished for the wire from the panel.  The 385 has a removable panel each side of the mast post, so we dropped the port side one of these and threaded a sizable cable above the head liner towards the hole for the light (which was still hanging down on its wires).  this is where the short lead from the panel and the thicker wire to the batteries are joined, in our case with a protection device that comes with the panel to protect it against back feed.  the a hole was drilled in the mast post above the level of the removable panel, and a grommet fitted to protect the cable, which was then fed into the mast post so that it falls down inside.  Then the part of the floor on the port side of the post was lifted and another hole drilled.  A thin bit of wire with a hook shape was used to grab the end of the cable, which was then pulled through and routed under the floor and up into the port settee to the regulator.  I can take more photos when i'm back on the boat.

We have a solar panel on the coach roof and it works as expected.

 If you can route the cable from the solar panel to the top of the mast post, there is an existing route to continue without any extra drilling. At least we have it on our boat. Pay attention that there have been different solutions of interiors of the Hanse 320.

 Because we remove the mast every year and disconnect all mast cables, we have an opening on the lining. On the picture you can see an end of a black tube in the middle of that opening:

 


The other end of this tube is visible on the other picture:


How to open it:


From there you can route the cable behind the control panel:


There is enough room to install the solar panel regulator, too. After it, you can continue to the battery compartment. Donít forget to install a fuse next to the battery.
