Deal Details
I found this deal while searching for a different solar panel. Looks like a good deal.

Reviews aren't the greatest, mainly people complaining about getting 70% of the rated output on the 100 watt unit.

"mainly people complaining about getting 70% of the rated output"

Which is going to be the case for any solar panel. You're never going to get the rated wattage out of a panel.

That's why I added the statement. So people could make their own decisions on the validity of the reviews.

In my experience, rigid panels get about 85-90% of the rated output, while folding portable panels get 70-85%.

There are some premium panels that do better, but you aren't going to get 200-300 watt folding portable panels from a premium brand for $99.

Other reviews are getting better than the 70%.

Thanks for the heads up. I just added it to the title.

I added it in the form, but didn't realize it doesn't show up until you open the post.

Legit solar panels can easily hit their rated output - not sure where people are getting lower numbers from. My 12kW system, on my last last house, near the USA/Canadian border would hit 10.8kWh with panels that didn't even face South.

The 200W version says it's 21" high x 114" long (and this isn't full coverage - that includes the fabric). Assuming a 15W/sqft of solar energy, the 200W looks like it could be closer to real, although I'd expect closer to 150W at most with the actual surface area of the panels, and average efficiency.

The listing photos show the "300W" as 8.7" high and 114" long? it must be wrong, or even more an egregious lie. That's under 7sqft of surface area, which would be under 100W of usable light, assuming efficiency numbers to hit 15W/sqft. That one almost appears like it's the 100W product photos?

Everything about this product screams fraudulent scam.

One should't promote fraudulent products.

I can't say I see anything that suggests "scam", here.

Potentially dubious quality/rebranded product, here, but you're also buying a solar panel from what appears to be a motorsports company.

For $100 for a 300w panel, though, it could be worth the gamble.

FWIW, as well, the 100w version looks to be on sale for $44.

Yep.
People will get rated output if they provide the specific laboratory conditions.

Excellent price.
I'd jump on this.

Before Covid , I paid $100+ for a 120W portable solar panel.

Where are people going to get a portable 200W solar panel for $99 these days?
