    @Bert, yes for carbon with rule of the thumb
    @jonr, will remove a panel just for short course racing
    @CDK Hi CDK, 1 MW/year is substantial power to think about putting in roof of my house some of these panels. AFAIK I live just 5 NM from you :) So, I can expect 1/5 of your instalation power in my boat, should be enough for autopilot, fridge and music :)

    Must be a little bit more than 5 NM I think.
    To the north and NW is uninhabited land, in all other directions there is only sea :confused:

    I was saying that we are neighbours because of insolation hours. SW of your place across the sea, maybee 6 NM. Of course, I don't want to bother you.

    Seriola, you may have tio check the one "17" on your drawing, Should it not be "170" also? Sorry mistake 170 should read 150

    Seriola, jonr is right, if you remove it all the time in anyway, find a good spot and create a simple way to remove and install the panel. All what you have to do is to bring a connection point out for your charger close by.
    Seriola, you better keep CDK as your friend :), he can really help you with electronics/electrical problems with advice. He is very good in that. Having him a phone call away, is always handy, special in view you both live in Croatia and not too many good electronics people are close by.

    That puts you in Sv.J. or Cunski! No bother at all, I am pleasantly surprised; never knew intelligent life was so near.

    Solar panels on stern towers are visually obtrusive and are always in the way when maneuvering

    I would mount the panels athwartships , aft...as a seating area area when not in use.
    Naturally you would need the proper shape panels and naturally some efficiency would be lost because of thier orientation.

    Hi Seriola, Or you fold the one panel over the other when not in use. By strengthening the backs of the panels, you would have a rigid construction and both panels would be protected when not in use. Use anodized aluminum hinges.

    I had a dream last night. A combination boarding plank , solar panel that stored aft as a bridge when sailing.

    The plank was a composite box section...solar panels on bottom, walking surface on top.

    The plank stored solar panel up when fit across the aft cockpit. Snap on cushions covered the panel when seating was more important than solar.

    For this invention I received a gold medal, started production in china and became a multimillionaire.

    Hi Michael, as long you told the Chinese to use 3 mm hardened glass. Otherwise you will be multi-poor instead of multi millionaire. But yes, it can be done and was done 35 -40 years ago. Start producing it.

    Why with hardened glass? Too many people will accidental sit on it when turned. Like CDK also had the experience from the early days of solar panels (thread 12), if hardened glass is used, you don't even have to turn it. Just take the pillow or cushion away. That is a really good dream Michael. Bert

    With small craft you are always seeking dual purpose for every piece of gear.

    In croatia a boarding plank is required because small craft berth stern to.

    The surface area of a 2.5 or 3 meter boarding plank might be enough for solar.

    I agree, in my case boarding plank with two panels will be heavy. Maybe with one little more than 10 kg. Boarding plank sometimes fall in water, scratch on shore end because of waves.

    The panels are available refer:

    You don't even have to turn the plank. Just walk over the solar panels. But you need to find a supplier for small quantities.
