Solar experts, what's wrong with these?

https://www.renogy.com/renogy-280-wa...e-solar-panel/

Unless that price changes between now and whenever you read this post, those 280w panels are selling for less than $1 per watt.

I'm in the final stages of selecting panels to purchase, and these things are so cheap I can't believe it. It's got me looking over my drawings to see if I can fit them on the boat somewhere (they're a bit large)

But, I tend to assume that something that _seems_ too good to be true, probably is. I thought Renogy was a reputable manufacturer, but these panels seem to be about 1/2 the typical price. Am I missing something that's bringing the price down?

Hell you can find panels for much less than that!

Don't blow air up my rear, be useful and blow it at the sails!

Re: Solar experts, what's wrong with these?

Yes framed panels are usually $1 a watt and often much cheaper.

Very few panels are sold online or through consumer channels.

Check out Sun Electric in Miami

It's the delivery that usually gets you.

Nothing obviously wrong with them, though I've never heard of Renorgy.

If a typical 60 cell module works for you, you ought to be able to get one made by a Tier 1 manufacturer for under $1/w. We pay about half that, but then we buy containers at a time.

I usually reccomend:

for diy folks. Good people, good support.

Re: Solar experts, what's wrong with these?

Renogy is a leading solar supplier in the world of people that think everything is available from Amazon and eBay.

Their panels and customer service have a great reputation.

I think the SCs they include in their kits are meh.

Surface shipping, especially for items that can be handled by one person, need not be expensive.

Of course, that required a truck with a lift gate and/or forklifts at both ends, which you would not need w/solar panels.
Arrange your own shipping and you can really save a lot of money.

Re: Solar experts, what's wrong with these?

I've had good luck with Renogy panels on my RV. Whistling down the freeway, freezing and thawing for years, no problems. Those are the typical 100 watt ones, however.

Buy a proper charge controller from someone like Morningstar, however. Don't use their kit garbage. Also, bear in mind that these are 24 volt panels, and will benefit, at least somewhat, from an MPPT controller that can take that extra voltage and properly utilize it.

Honestly, as others have mentioned, look around. There are probably better panels, and cheaper. Renogy made their name selling small 12 volt panels on Amazon. The big grid tie panels you get from SolarWorld for example are $0.79 a watt right now.

But for someone looking to spend under $500 all up, that sure adds to the $/W cost

Re: Solar experts, what's wrong with these?

I guess I asked the wrong question, then ...

What's wrong with these ones that they're so expensive?:
https://www.solar-electric.com/solar...lar-panel.html
https://www.renogy.com/renogy-eclips...e-solar-panel/
https://www.defender.com/product.jsp...050&id=3615096

Yes, there are others in the ~$1/watt range, but the lions share of these panels seem to be 2x that or more.

Shipping from Miami to Ohio isn't liable to be any cheaper than any other shipping ...

The biggest problem I have with Sandusky is how small everything is. The West Marine there is the size of a convenience store. As best I can tell, there's only 1 rigging/sail expert. And there doesn't seem to be anywhere that will sell solar panels retail.
