HQST 100 Watt 12V Monocrystalline Solar Panel High Efficiency Module PV Power for Battery Charging Boat, Caravan and Other Off Grid Applications 31.8 x 27.5 x 1.18 in (New Version)

First thing I did when these arrived was plug them into my Bluetti battery, one at a time, this was later in the day, but both were showing 80W on the battery, this is a good start because the conditions were far from ideal.Next day, I fitted them to my BougeRV adjustable stand, on a homemade wooden trolley, as the photo shows, and connected them in parallel, then plugged in, 140W from early in the day, that's a very good result, they typically then managed around 175W in relatively hazy conditions, if you get the occasional cloud, you might witness 'cloud edge effect', this can get them to over 200W when connected as a pair, but in general in full sun I get at least 160W for most of the day, they will peak at 180W a couple of hours around midday, but definitely the average in Southern California is 160W from 10am to 4pm, during winter and of course longer during the height of the summer, peaking at around 10+ hours at an average 160W.My trolley stand does allow me to follow the sun, which is a major benefit, value for money these are incomparable, at $0.50 per unit of electricity, and generating between 1 and 1.6 units a day, payback is easily going to be achieved in less than a year.I love these panels so much, I've now got a total of 10, all producing enough to mean my electricity bill for a 4-bed house, with me working at home on computers all day, is around $40 a month, excellent.

10 watts less than 200 watt panels at a large cost reduction. I have now purchased 10 of these panels to replace some older BP 175 watt panels, and they are much lighter and smaller. I also have an array of 6 100 watt HQST panels that are decades old and still performing well for me, that is why I went HQST again this time. HQST panels strike me as well made and reliable. Sturdy as well. I live in Florida and the 100 watt panels have done fine through hurricanes and hail over the years.Only gripe is the packaging. A little tape on the boxes would keep them from being delivered open and torn. Most of the panels arrived fine despite the torn up boxes, so the packing itself is AOK. How about just a little tape on them though? 4 of the 10 panels had dented aluminum frames but none so severe that the panels were unusable. All 4 dented panels had fully opened boxes when they arrived so I imagine they probably fell out of the boxes at some point. A little tape would have prevented that.

Bought these to experiment with my EcoFlow River - after watching quite a few reviews on YouTube of the various 100w panels this brand seemed like the best mix of quality and price.Once they arrived I was not disappointed - I can use just one panel, or put them in parallel ( with an additional cable ) to use together. I do not have them mounted and just bring them out and lean them against the house on sunny days.Overall heavier than the Ecoflow foldable panel, but less expensive. Because they are in a frame they can me propped up easily and stay where I put them.The company ran a special about a week after I bought them and they were easy to contact, and did not ignore me. They did give me a little credit to match the special they were running. Overall they seemed easy to work with and reasonable.I am really happy with the quality, and the amount of energy I can get out of the panels when it is sunny. Of course the entire panel has to be in the sun, outside and not shaded for best results. The ecoflow will show you how much power is being produced and you can optimize the placement and angle to get the best results for your location.

I installed four of these panels on the roof of our RV. Instead of buying the all in one kit I decided to piece my own package together. Mainly because I was limited on space so four panels is all I have room for. Instead of four 100 watt panels that seem to be the most common at the moment, I installed four 190W panels. I looked at other brands like Rich Solar as well as a couple others (GoPower, Renogy) but chose HQST over them. These were priced fairly and in doing some research the reviews were all positive. I installed these with a Victron controller and they are working great. Installation was easier then expected.Packaging was good and the panels arrived in perfect shape. Foam protects the corners. There is also some foam covering the outside middle panel edge. This was more than sufficient to get them to me safely.I bought the HQST mounting brackets as well as the HQST wiring to connect the panels to the charge controller.If I were to make a recommendation more mounting holes to add some additional installation flexibility would be helpful though this doesn't seem to be available with other brands as well. With the help of a stud finder I was able to line up the panels to the hit the studs within the roof. Some additional mounting options would be nice. Overall it wasn't a difficult installation at all and everything is working perfectly.

They work - get them. Was able to get a 2-panel set-up (including panel-to-panel and 10ft connecting wire) for around 100bucks. Now have 2x100w panels to charge an Eco-Flow Delta II in emergency. Each panel easily produces ~94w in good (but not perfect) sunlight. They work-great price - what more could you want.
