These are more portable; you would probably need a substantial system to charge that.
I still want to mount this on my shed for shed power rotflmao.

as above, i would recommend a set of longer cables and use the panel stand to move them into the sun
cheap trick, get the 12/2 extension cords from costco, cut to about 30-40', this is the cheapest 12 gauge wire you will find
with the remaining length simply make a shorter extension cord


here is a decent vid that may help you get some ideas:

Awesome, thanks!

Yeah, I'm surprised at the amount of negativity threads like this create.
Great video. Always wanted to go down the solar rabbit hole.

Because if it doesn't make any sense, why would you
1. Have a wind turbine
2. Have a 1440Ah battery bank?
So let me get this straight.

Simply because solar needs batteries to give power when you want it, that means "Solar is just a gimmick in Canada"?

You extol wind power, but what about the summer months when wind dies down for weeks at a time and trips to remote areas is way more frequent?

This is a small Costco panel for niche applications, and we're on RFD ffs, where you will literally find thousands of near-useless things for sale. I don't see you whining about all those...

Anyone have a thought on how long this would take to charge up a boat battery and trolling motor battery. Or if it would even work well? We don’t have power at our dock and this might be a good option. Thanks

Yeah, these wouldn't be the right product. But more generally, thinking about a a DIY with several panels (8-10x) getting up to maybe 3kw. Of course, then placement and permitting is the challenge.

I was thinking of getting a solar panel for camping. However I wanted to connect to a solar generator. I dont plan to carry around a 12V battery. Anybody know if this would charge a solar generator?

Also this doesnt appear to be monocrystaline which I believe is the most efficient.

Its all in the math.. Figure out how many amp hours are in your trolling motor battery is. Then you can figure out how long it would take to charge in full sun.

E.g.

12V @ 98Ah (means you can draw 98A for an hour or 1A for 98h or anything in between)
Deep cycle lead acid batteries should NOT be drawn below %50 so you have 48Amp Hours of usable energy. Lets assume you draw it all.

So that solar kit can put out a maximum of about [email protected] (in full sun at high noon). So if we average that out to about 7A over a day.
48 divided by 7 = 6.85 hours to recharge a typical marine deep cycle battery from %50!

What is a solar generator? I have never heard of anything like that? Are you talking about a power station (like a Jackery or Bluetti)!

As to Poly vs Mono, in a system of this size it makes pretty much ZERO difference. Even in larger systems, the technologies are close enough now that you can go with either. There are advantages and disadvantages to both (e.g one is better in cloudy situation, one is better in hotter climates).

There is probably a battery inside the solar generator already. Check your model.

i think what you are referring to as solar generator is actually just a 12v deep cycle encased in a fancy enclosure with an inverter built in

300 watts wont go very far, also quality is important in inverters.

The Coleman is a complete unit, in that it includes the solar panel, a charge controller, and a power inverter. Still need a battery, though. You might have guessed from the comments here: 120W isn't really that much, the charge controller is pretty low-end and inefficient, and it's the same story for the inverter. But for a specific and limited use, it might be ok in the right circumstance.

The Bluetti you linked to includes only the panel. The panel is more portable and likely more efficient than the Coleman. It's sold as an accessory for a Bluetti solar generator, which already has a charge controller and inverter built-in. The quality of the latter two will depend on which solar generator you pair the panels with, but all are likely to be of higher quality (and much more expensive) than the Coleman. Of course, the Bluetti doesn't need to be matched with other Bluetti products - you can use your own solar charge controller, battery, inverter, etc.

The best part about this kit is the Costco return policy. Ultimately that's probably what most people will end up doing with it.

For a similar price (though without the nearly useless 300w inverter) better, more complete options are available.

https://ca.renogy.com/100w-12v-monocrys ... ontroller/ 161.99 or $145 after 10% off code (willprowse)


https://ca.renogy.com/renogy-100-watt-1 ... arter-kit/
Same as above, but with a 30a charge controller, which will allow you to expand the system with up to 3 more panels. $199, or $179 after 10% discount code.
And for $50 or so more, you can get a portable send contained folding kit.

This is not really a great deal. The panel is suspect and the charge controller is a complete POS. You can get a renogy 100 watt high quality panel off amazon for $100 and a decent PWM charge controller for 30 that has a display, USB charge ports, Multiple battery support AGM, Lithium etc. The inverter is a 20 buck POS as well but even still you would be at 150 and have way better equipment. If you are going to get multiple panels its worth the dough to buy a decent MPPT charge controller. they start at 100.
