Cheap flex solar panel

So guys I must be a skinflint magnet
The manufacturers know I can't resist a deal or two .

I have received these flexible solar panel deals lately

https://www.ebay.com/itm/100w-16V-Fl...edirect=mobile
11 bucks delivered the only catch I have found is you can only get one per 10 days.

https://www.ebay.com/itm/200w-Solar-...edirect=mobile
22 bucks delivered same thing one set per 10 days.

At that price its worth the chance . Heck the controller in each kit is worth that much .

Re: Cheap flex solar panel

I would be very careful with low buck flex panels, with all of the failures and fires and or burnt spots

IOW hang them on the rails with zip ties . Not solidly on the canvas bimini
The price is cheap enough to stick them under your vee berth till you suffer a catastrophic failure of your $400 dollar ones . These will save the trip.
We shall see

Re: Cheap flex solar panel

Looks like a scam to me. Check the feedback, most good ratings are duplicate buyers with less than a 100 transaction. Then click on the 12 negative ratings for this month.

Beware.

This is what will happen to the cheap ebay panels. The plastic will get cloudy and starts to look like crap.

I bought two five years ago, they still work great, but I have to polish/buff them about every three months...................

When I do replace them, a lot more research will be done.

stop polishing your flex panels the opacity will not have a significant effect .
However repeated polishing and rubbing on them will cause micro fractures in the cells themselves causing hot spots and premature failures

the opacity is not an issue it will not effect the panels output significantly.

My OCD will not allow a couple of crappy looking solar panels on my hard top.........

They've been there five years but are on the short list to be replaced.

Almost too good to be true on pricing for 2 panels, cables and regulator. Am waiting to see what you think of them when they arrive.

Was going to order them yesterday also, but the seller has a vacation stop on orders at this time, so need to wait. Apparently the 1st link you attached w/ the single 100W panel is no longer on ebay and the seller isn't registered anymore. As someone suggest that one may have been a scam.

It seems like you got the extra coverage from Square Trade. Seems good for $2, if it actually covers the products like they claim. Has anyone ever tried to make a claim with them?
