Bests & Worsts Reviews from Amazon

Overall, I think this is a great panel. I have used it with a jackery 1000, as well as a DIY solar "generator" setup with a 30a PWM charge controller. In full sun, solar noon and laying flat on the roof of my car, I was able to get 97.5 watts out of it using a PWM charge controller. For a 120w panel, that is pretty darn good. It seems well made, and has stood up to the Tennessee heat pretty well so far. While I do think this panel is a good value for the price, and will more than likely be buying a second to run in parallel, I don't feel right giving it a full 5 stars. It definitely falls somewhere between 4 and 5. Overall, as long as it holds up well over time, I definitely believe this is at least a 4 out of 5 product, but probably somewhere around 4.5 stars. Here are a list of the cons (and subsequent reasons I cannot in good faith call this a "5 star item"). I do certainly hope TP-solar reads these reviews and uses this criticism to improve future iterations. First, the DC output cable should be a bit longer. Maybe a foot or so more. Additionally, while it is not obnoxiously "thin", I would have preferred a beefier cable, especially since I have seen this panel put out almost 7 amps. Secondly, the accessorie cables that come with it, while a nice gesture, are quite frankly very poor quality. Particularly the mc4 cable and the battery clamps. While I don't know the gauge cable used on these items, I will say it is VERY thin, and feels as though just the act of connecting and disconnecting the mc4 connectors could cause damage to these wires. I would have liked to have seen beefier cables overall. Keep in mind, while i agree that it is generous for them to offer them in the first place, any cable that is too thin and prone to damage is almost not worth including at all. In addition to the thin accessory cables, I wish they did a better job of communicating the output cable sizes so that longer cables or more robust cables could be purchased easily. After some homework, I believe the DC output is a male 5.5mm x 2.1mm... but I have yet to have that confirmed by the manufacturer, and I dont feel like ordering anything and "hoping it works". Third, I think the biggest failing point of this panel is the junction box. If the panel is "waterproof", find a way to make the junction box waterproof as well. Period. The way it's designed now, the panel being waterproof is pointless. If left out in the rain, you will get water in the junction box, and the panel may fail due to that. It should not be the responsibility of the end user to engineer a way to waterproof a "waterproof" panel. Other panels have utilized some sort of waterproof cover over the junction box, and hopefully future runs of this otherwise great panel follow suite. Lastly, and this is a minor gripe for sure, but the carry case is WAY too tight. I cannot fathom why it is so tight. The panel is a pain to put back in, and this could have been remedied by simply making the width a few millimeters bigger. This should not have passed qc like this. Having said all that, I do feel like this is a well built panel. My cable issues aside, it does what it was built to do... take in photons and put out watts... and it seems to do it quite well. I think the biggest compliment you can give a product is to purchase it again, and like I said, I am about to order a second one. It plays nice with both my Jackery 1000 and my DIY solar setup. It appears to be well constructed, and I hope to get many years of service out of this panel. If I was grading it based solely on solar production, it would be a 5 star panel in my book. Numbers don't lie, and I've attached a photo of the readings from my inline power analyzer, which is attached directly to the panel's output. If you can live with the cons I've listed above, I'd definitely recommend this lightweight, portable, easy-to-setup panel that is priced very competitively. I bought this panel with my own hard-earned money. I have no affiliation with TP-Solar whatsoever, and have not recieved this product for the purpose of review. I bought it, I tested it, and I wanted to share my thoughts for anyone interested. Thanks for reading!!
