2 x 100 w panels would take up an area of about 4ft x 3ft .if my calculations are correct that should fit on even a 8 ft boat.. will it would in Australia or Philippines but mabe not in USA??..
Recalculating this it seems that it would be possible to fit 4 x 100w panels on an 8ft boat.. and its very possible his boat is longer than 8ft..

Jon boats are available commercially between 8 and 24 feet (2.4 and 7.3 m) long and 32 to 60 inches (81 to 150 cm) wide, though custom sizes may be found...[COLOR="As the original post did not give the length of the boat it could be up to 20 ft and could easily carry 4x 100 w panels.
also many trolling motors have a max draw of 50a if that the case then 4 x 100 w panels would provide about 50% of the motors power and its also not likely to be running at full power all the time. mabe he will stop for some fishing and a joint to smoke while batteries recharging.#000000"][/COLOR]Leave a comment:

If his boat is already 12v and powering the motor I seriously doubt its drawing 200 amps. or the batteries be so big the boat will sink.
IF 2 x 100W panels are larger than the boat it cant be carrying a 1000 ahr battery..Leave a comment:

50 amps
If it is a normal size trolling motor, most likely it is something like 50 amps max draw. 1 amp per rated pound thrust is a good estimate. Still, yeah would be using up a lot of valuable cargo space to have enough production from solar to do much with.Leave a comment:

JohnP good try, but you are still smoking Ganja and day dreaming in the Philippines and Australia. Yes John I know who you are and can track you.
2 x 100 watt panels are larger than a Jon boat and if standard 12 volt battery panels are used will deliver 10 amps or 120 to 150 watts to a 12 volt electric motor. Electric trolling motors are 1 to 3 Hp which require up to 200 amps. Nice try, but you do not fool me.Leave a comment:

What is the current draw of the motor? If its less than 20a then 2x 100w panels would supply most of the power it consumes between about 10am and 2pm, but would drop off a lot outside those hours.Leave a comment:

Well here is a good question that begs an answer. There is no amount of panels you can put on a Jon boat to do any meaningful work while afloat to charge your Marine Trolling motor battery. It would be silly to try and not to mention great possibility to sink your boat. Glup, Glup! It will take a panel the size of a house to recharge your battery in a single day. Do you think a little 2X4 panel will do anything other than recharge a Cell Phone battery in a day? I would love to see you try it so i can film it and post on Red Tube.Leave a comment:

Leave the panels connected. Even if they are not charging the battery, they are supplying current to the load which would otherwise have to be taken from the battery. Net result is still good.
Imagine that the panels could supply *almost* enough power to run the motor. After 1 hour running with panels connected, battery will be close to where it started, even though it has never actually seen any net charge. Without the panels, the battery would have been running the motor on its own for one hour and be significantly discharged.Leave a comment:

charging batteries while motor is running?
I have a simple question…… I have a jon boat that runs on 12 volt power. I want to hook up a solar panel or panels to charge the two batteries. My question is while on the water do I need to detach the panels while I’m running the motors. I would like to keep the panel/s attached so as soon as I was stop….no longer running the motor…. the panels would instantly start charging and I wouldn’t have to worry about hooking up and unhooking the panels. So is it safe to hook the panels up and just leave them attached?
