My carbon footprint just dropped a shoe size!
I've been wanting to detach from shore power - I use so little, but pay for it every 30 days.
In 4 months, my solar panel of choice could pay for itself.
Then I signed up for an Amazon Prime Store card - they sported me $50, which I used to fund this:

It's hard to argue with instantaneous payback!
And it took all of 10 minutes to install & start drawing power from the nearest star today.
Looks good, should keep your battery in good shape.
I am really interested in how this works for you here in the North West. I looked at it on Amazon but as usual the reviews are mixed although mostly positive.
It's been raining here for the last week, with some indirect sunlight.
When I connected the panel, the battery level was at 10.6. Today, it was at 12.5... so I'm feeling confident that this will do what I need.
For areas such as the PNW you may benefit from a MPPT regulator. Here is a brief explanation of their operation and benefits.

It also points out a commonly overlooked fact that 10 watts at 17 volts is not 10 watts at 12 volts, so you have to get into a little bit of arithmetic when calculating power requirements. Working with the new technologies for power generation and storage is somewhat different than the standards we are accustomed to. Kind of like going from American standard measurement to the metric system. Have you noticed the increased use of three batteries instead of the traditional 2 or 4. OK, OK, I'll take my spoonful of new math.
Yeah, it's crazy the way technology is creeping into the sanctity of our sailing tradition, pretty soon they will be making our boats out of plastic. Ghastly!!!!
Thanks ChuckD. Yes finally some sunshine down here in Oregon. Another question, did it come with a or did you also buy a voltage controller?
Retrafwo,
It comes with one, built-in.
Sun dance!
thanks ChuckD, I think I will go with the same model, maybe compare notes later in the season.
Great - keep me posted!
Notes:
. My mounting bracket is slightly different than pictured on Amazon, but I actually like it better - it's adjustable. Installed in minutes, started drawing celestial power!
. I also got one of these, which I love (took about 10 days to arrive): https://smile.amazon.com/gp/product/B008KY5ULW/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
Good job.
Glad you have a charge controller. Here is a little supplemental information on charge controllers:

Take a look at that guy's site for other posts. He does a pretty good job.
Thanks, HeaveTo...
I recall reading that when I was shopping for panels.
Tons of good info!
You will LOVE having solar. It is a good method of keeping things charged up. Leave the boat and come back with full batteries without having the worry of shore power. It is also nice if you stay on the hook.
Enjoy!
I just came across this and found the comparison interesting. http://www.lensunsolar.com/blog/what-is-different-with-lensun-flexible-solar-panel-with-others/
found a 30W coleman solar panel on ebay. Also a nice little sunsei mounting kit for $20 on Amazon

Nice panel Wayne. It seems like a reasonable size for the boom gallows. How are you planning on running the wires and what size battery are you charging?

I mounted a 25 watt (12 v) panel on a 4x4 post that is right beside my trailer. While the panel stays "home" it keeps the battery (about to have two batteries) charged nicely. I have a simple automotive trailer plug between the panel and the wire that leads in through a hatch to the battery. Makes for a simple disconnect when I go sailing. Of course I have a solar charge controller between the panel and the battery. It's secured to the post and shows charging status. Everything should run you about $60 plus post, unless you want a nicer charge controller. Right now I am running a depth sounder and electric motor. I am adding the second battery for more storage. Works for me.

Gary,
What kind of batteries are you using?
a pair of deep cycle marine batteries - 650 cca- group (size) 24M from Wall mart
