which panel to buy?

[j3ffr3y]

Hello everyone,

I have an opportunity to buy individual GT panels from a local warehouse (usually only sells by the pallet). I have the option of either of the following panels:

Topoint JTM250-96M
250W
Vmp = 49.91V
Imp = 5.02A
Price = $200 Cash
SolarWorld Sunmodule Plus SW 255 mono
255W
Vmpp = 31.4V
Impp = 8.15A
Price = $250 Cash

Initially, I would be using one of these panels at my recreational off-grid cabin (12v 215ah GC battery bank) with an MPPT charge controller (probably the new Rogue)
Any opinions on these panels? Is one better than the other for my 12v charging?

Thanks,

Jeff

The panels probably have different physical size. Does one fit better than the other?

I didn't really pay attention to the dimensions. That isn't an issue. I'm using a top of pole mount and have plenty of room/adjustability for whatever size.

I have never heard about the Topoint panels. But I agree with sensij that those maybe 72 cell panels and much bigger in size and weight then the Solar World panel which is probably a 60 cell unit.

Hey all,

Just wanted to follow up...

The Topoint panels were actually 96 cell panels.

I ended up picking up (2) 255W Solar World Panels for $300. Don't know if I'll use both at the cabin or not, but I figured the price was too good and I'll probably setup a small backup system at home too. So the extra panel won't go to waste

Now to look for a mppt controller...

Thanks for all your help!

If you decide that you don't want one of the panels, let me know. I'm looking to build my first system.

Blue Sky makes a SB2512i-HV charge controller that is perfect for 1 panel.
