I'm trying to hook up a solar panel just to run a small radio/cd player on my boat so I dont have to worry about killing my boat battery. I am trying to figure out what size I need, can anybody help? Thanks

You need to have a panel that can replenish what your radio consumes. When we know:
1) how much the radio draws
2) how long you play it daily
then we can caculate what size panel you will need.
Anything else is a wild guess you could make.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

You are going to need more than a solar panel. You will need a charge controller and another battery or your boats batteryMSEE, PEComment

Ok I understand the idea of what has been said here but to have a sun cannopy that jams sounds like a great project let us know how you do on that. with it being a boat I would like to know the size available for cannopy first off let see what size of panel you can aply?
then you can work out the hours of your party time this is going to last well into the night you might be able to but you would spend more on feul carrying all the extra batteries to run past duskComment

Well everything depends on what kind of radio he is talking about. If this is just say something like a 5 or 10 watt output, you are wasting your time and money using a solar panel and extra battery. Your boats starting battery can handle it just fine.
If it is a high wattage output stereo, then you have something to worry about, but you do not need a solar panel or a charge controller. Just install an auxiliary battery and a battery isolator. Run the stereo on the aux battery, and let the boat motor charge it up when it is running.MSEE, PEComment

I'm talking about a 180 Watt cd deck with 2 small speakers. I understand the motor charges the battery but I only use the radio when it's anchoredComment
