Solar panel video - Blacktank - 07-23-2018
was checking out the solar panel market and came across these https://www.ebay.com/itm/2-200-Watt-12-Volt-Battery-Charger-Solar-Panel-Off-Grid-RV-Boat-400-watt-total/273171689924?epid=22014282799&hash=item3f9a4d31c4:g:y5wAAOSwwZtacRkO
and i have to research everything and found a walkthrough of their manufacturing plant,a little look into how panels are made

Less than $1/Watt shipped if it really is 2x200w.
Title says "2- 200 Watt 12 Volt Battery Charger Solar Panel Off Grid RV Boat 400 watt total"
Description says "this is for 1-200 watt solar panel"
I wonder how they are shipping it; will cost them a ton.

Link to YT vid of a guy testing and reviewing 4 different 100watt panels.

On the recommendation of Jim, we ordered these panels.
The first three were not to specification. One text to the seller got instant response. Three new panels shipped out, and keep the old ones. The same with everyone that got the defective batch. I am impressed at the output on these units. The description is not quite right. For $380 you get 2 panels.
I would buy them again.

I remember seeing that vid back in the september OP.
The ones that you lost ?
RE: Solar panel video - GotSmart - 02-25-2019
No, the replacement ones. Tomorrow starts the solar install hopefully with tilt.
RE: Solar panel video - rvpopeye - 02-26-2019
Cool
I thought the others were Renogy.....
Good chance to test some different ones.
Gonna mount 'em differently ? Duh ! Nevermind.....tilt.
Out of spec ,,,,in what way ? Maybe more tests , possibly portable , a giveaway , already gave away , or maybe save 'em for "something back at the ranch" ?

I have been suggesting these panels in my designs for quite a while now. It's easy to fit four of them on a van for 800 watts. The newest version are called 200 watt + because they are bi facial and will pick up 127 watts if the rear is pointed at the sun. I have been suggesting the Victron 50 amp Smart solar controller because it will be rarely over paneled and saves $200 over the 60 amp version.
The defective panels were part of a bad run where a insulation failed. It caused the panels to lose a string of cells. In this camp alone the seller will replace 9 panels even though 6 are okay. They are a made in the USA product and the manufacture stepped up. The 3 bad ones would have to be run in series to be of any use.

I can buy several brands for 34 cents a watt new, I'm looking at 4x325 watt panels & these are an hour away so no shipping. Planning on wiring them in series put them on a trailer so I cab park the ambi in the shade & still getting good solar.
RE: Solar panel video - justjim - 02-27-2019
Don't wire in series if you are planing on being in the shade. One panel partially shaded will take them all out.
