Amazon Customer –
I’ve ordered a total of 12 of these panels, and have 9 panels to show for it. I ordered the first group through Prime. The panels are packaged terribly, and if there’s anything that hits the center of the box then one or both of the panels will arrive broken and unusable. One of my boxes of two panels showed up broken, and I couldn’t believe how it was packaged. As you may imagine, because of the size and weight, it’s a real hassle to repackage and send them back to Amazon for a refund, let alone putting a total stall on my solar install. The second problem I had was trying to save a few bucks by ordering the 4 panel shipment (which IS NOT Prime). Do Not, I repeat DO NOt order these in any way other than Amazon Prime, as temping as it may be to try to save a few bucks. You won’t know it when you order, but I just received my panels today after a 5 or 6 week wait, and only received box of 2 and not the 4 panels. When I contacted Amazon, it was a time consuming and frustrating negotiation to get a reasonable refund of 50%. Amazon wanted to only refund 30%, not the logical 50%, and even that was after an hour or so of back & forth on chat customer service. I had to try everything to explain to Amazon I had purchased the product through them, not the manufacturer. So in summary, a good product, but really poor fulfillment on behalf of the manufacturer for any of the non-Prime product listings on by manufacturer. Buyer beware of using Amazon whenever it’s not Prime.

These solar panels are bigger than I thought they would be but seem to be great quality. Good buy

Have 4 100w Renogy panels which actually make 400w in full sun. Was expecting similar with the 320w ones. Never seen much more than 250w each from 4 of them. Had them configured 2p2s to a Renogy Rover 40 (same as 100w ones use). Split them into 2 strings of 2s1p to a 3rd Rover 40. Same exact wattage. Kindof a bummer.
At least they arrived undamaged.
The attached graph is meant to show the 4 100 watt ones putting out over their 400w rating several short times, while the supposed 320w ones never got over 951w, which is less than 250w each. Misleading to call them 320w and should be called 230 or 240w.
Thought maybe mine were defective, but there are a couple other reviews that mention 250w each for them.
Wanted to buy 4 more, but too expensive when you consider the wattage they actually produce.

Rated maximum of 720w for both panels but after 1 week of good sun, it can only produce at its peak a total of 640w. The panels are extremely heavy so definitely plan to have extra hands to help install them.

Straight to the point
I almost did not pull the trigger on this solar panel because of its service review. My first order of 6 panels finished w 2 panels crushed, I sent some pics and a description. The Brocken panels were replaced without an issue. My next 6 panels plus the 2 that where replaced all arrived safe and sound

Work great ! Replaced 2 (out of 3 in the small array) Renogy 270w, 24vt polycrystalline panels destroyed in a 75+mph line squall, when the whole anchored mount came out of the ground and went airborne.
(Let me interject at this point . . . the original installer of this system I ultimately inherited, was unbelievably ignorant surrounding most all aspects of his installation. My advice? If you contract a complete system solar installer, seriously do your DD and if possible, get recommendations and inspect his/her completed projects. I have had to add myriad protections, calibrate all components to match factory engineering specs and completely replaced the ground mount array supports. I have decades of experience to match my low voltage education and certifications/licensure(s), but most people having a system installed will hardly ever know what they’re buying. The original owner found this guy on FB and just took for granted someone on FB would tell her the truth about his qualifications. He, of course, didn’t ! )
Adding these 2x320w mono-crystalline panels, (24vt rated and having a near identical physical footprint to the damaged 270w panels) exceed what should be a combined output spec by around 10% (+/-) without stressing the original panel’s tolerances.
Needless to say, I’m quite happy with my purchase.

They produce 40v when disconnected, as they are rated.
