I have  been  looking at an on-gird 250 watt  48 volt panel (CS5P-250M) made by  Canadian  Solar. unfortunately  the warranty does not  cover marine  use, which is common. Do you any of you have  experience with modifying solar panels so they are more  protected from salt than  land use? The Canadian  Panel is so  cheap,  < $500 that I am willing to take the risk,  since it will  produce so much more  power.

I'm definitely not an expert on solar panels but I'm seriously in the market for some as well. I would be curious to know what actually makes solar panels "for marine use?" Being outdoors, they have to be rugged no matter what. I would buy them and use them as they are. They're probably OK like they are for use on a boat, and you pay extra, just for the "for marine use" label. I have quite a few things on my boat that weren't made for boats that work just fine or better and cost a fraction of the cost. 

I have  made a huge error.  The Candian  Solar panels will NOT charge a  48 volt system, since they  are "on-grid"  panels that have  a working  voltage near  48 volts. You need, " off grid panels like the one below that has  a higher working  voltage to  get the  electricity to  " flow"  to the batteries properly. There panels are apparently  quite  sturdy and will not need to  be " marinized:

I've never had a problem with a solar  panel installed on my boat.  As long as the mounting is secure I don't see a problem. Just make sure no one can walk on it.  IMO I think they are just protecting themselves from a bad installation on a boat not salt water. Otherwise they would not allow them to be mounted along on land on the coasts of Canada either.

Awsome weekend

Got out for 3 days done about 30 miles under power @ 35amps 4 kts average Got in some good sail time sill working on the regen I am only getting about 2 amps @ 5.5-6 kts got to work on this still its better than nothing. Got to run the EU2000 (about 2 or 3 hours total) to run the chargers and fix dinners as all my cooking is electric also cooking with the inverter eats a lot of power and I am pretty sure I would have to cover at least 2 boats with panels to keep up works pretty good for coffee…See More

Do you know anything about St. Pierre Dories?

I have just gotten a 22' St. Pierre Dory, it has not sails or rudder, but it does have masts. It is a doug-fir ply dory and the late John Gardner consulted during construction. I can handle the basic plywood repairs and scraping old paint etc.  I have no knowledge or experience designing a rudder or sail plan. I have a home built trimaran 28' that I am thinking of scraping since it has electronic propulsion and large sails. If you become my sailing friend and help, will keep fed, will pay for…See More

Gen set

I am going to pick up a Honda EU2000 this week to run the house and charger when on the hookFor those of you that use a portable gen what is you opinion as to where is the best place to mount and run it. I rented one last week and made sure that it would meet my needs and was pleased to find out that it ran every thing in eco mode ( charge-toaster oven and even the water heater one @ a time of course ) I ordered the companion so I will be able to use the 30A shore power cord so I will be able…See More

Major test run

Took her out for her first serious test run on the 23rd January. Everything performed very well. Ran the electric motor for over an hour at 4 knots. The batteries still had plenty of charge left in them. My prediction of motoring for 3 hours at 4.5 to 5 knots is looking good. The outbound trip was against the tide and the yacht has not been anti fouled in 2 years. In the tropics the growth underneath is very fast. Once she is antifouled I will get another 1.5 knots.Charged the battery bank via…See More
