Renogy 320W Solar Panel

I feel like I have enough experience with these panels now to write a review. I’m not going to be overly technical or anything because I don’t have that type of background or ability. I’m just going to tell you my experience and how they’ve worked. I’ve ordered these panels three times and I’m ordering another two now. My first order one of the panels was shattered. I contacted Amazon and they sent two more panels out and did not force me to send the other panels back. Meaning I got three panels that were working even when I’ve only ordered two at that point. I expanded the array by ordering more panels. And again expanded by ordering more yet again. One order was damaged out of three, not to mention the replacement that they sent which can be considered a delivery or order if you want so four deliveries with one panel damaged. In total, I have eight panels. I’ve had these set up 2 series 4 parallel, 3 series, 2 parallel, 6 series, and 4 series 2 parallel. All worked as expected and excellent. Right now I have 4 series 2 parallel, which is sitting at about 120 something volts as my new inverter requires 120 V before the MPPT makes use of PV. This is why I’m ordering two more so I can do five series 2 parallel and be well within range for my MPPT. That said eight panels is 2560 W, after inverter and light load of about 200 W I am getting about 1950 W into the batteries after load. I would say that pretty nice for the panels. When I get the two more panels, it’ll be 3200 W and based on my experience thus far I expect to get between 2400 and 2600 watts charging my batteries daily, slightly more actual wattage running inverter and light load. The connectors on the back of the panels are easy to work with and seem to be very well-made. All the seals and seems everywhere with the wires and the seal to the frame seem to be well done. I happen to be very lucky to have the extra panel that Amazon sent me when one was broken because of the wind storm that shattered a panel that was in the active array. So of 10 panels that I’ve had eight survived. One died in shipping, one died in the line of duty. I’m very happy with these panels. I wish they cost a little less, but they are reasonably priced. I get five stars because the shipping incident was taken care of and the panels have been performing very well in many different configurations. If I had to do it all over, I would have ordered all the panels in one shot instead of making multiple orders. However, it’s worked out and I am happy with the purchases panels have been working for about two years now.

Very happy with these so far. With two installed, I am getting over 500W. They seem well made, were easy to install, and fit well in different places. I had to drill new holes to mount them on my van’s strut, but they have held securely since then.

High quality solar panels that perform well. By purchasing a package of two panels, they are a better value. I have used different Renogy solar panels for the past ten years and have found them reliable and easy to mount and install on my RV's without adding too much weight. I will be using the new 320 watt solar panels on my off-site storage building.

These are big heavy and made out of non recycling products, I love the whole idea of solar. And after studying all the information I can get my dirty little paws on I've come to the conclusion at this point in time our history solar energy is a waste of time money and the Aggravation caused by worry and experimentation, I can't review these yet because I'm back on the road, I got not time for foolish things lol... I have been successful in this solar thang and probably will continue with it, But not going full throttle until it actually gets a lot cheaper, why because there playing with us, Solar energy has been around for years like a hundred now no really, there's equipment they won't sell us that does really well but we can't have it, the available equipment is very expensive and what is only available to the science community would blow your mind. Sanyo corporation used to make panels in the 90s only 200watts that put out around 63v at 27amps can you buy anything like this today oh no they want to sell us equipment for mega dollars that barely lights up a 15watt led, No solar today is not worth dumping thousands of dollars into, To date I've purchased 8 of the 320watt Renogy panels. There big there heavy and they work well. These are base work horse units that produce around 280watt average as no solar panel puts out advertised wattage from a perfect world lol...

Shipping is totally awful. Boxes are not rated for ground shipping. Panels arrived damaged, customer service offered to send replacements. Never did. Had to file an A to Z Amazon claim to get a refund. Warning! Read the reviews, poor customer service!

Affordable and easy install. Why spend big money when you can get the biggest bang for your buck with Renogy. Added to my existing 2-330W solar panels.

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.

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.
