HQST Solar Panel 2pcs 100 Watt 12V Monocrystalline Solar Panel with Solar Connectors, High Efficiency Module PV Power for Battery Charging Boat, Caravan, RV and Any Other Off Grid Applications

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.

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 purchased tow of these solar panel to go with my newly acquired Bluetti EB150 solar generator. Each panel is rated at 100W. I have them connected in series to connect the Bluetti. On this fairly sunny day with some wisps of clouds in the sky in later afternoon, the Bluetti says that it was taking in 178 - 181W of solar energy. A few days later, I just needed to top off the Bluetti so I set up just one panel at around noon time and the Bluetti said it was taking in 99W of solar energy. Incredible. Very pleased with these panels. They aren't too big and are fairly light. I may get another pair later on so I can put each pair in series and then put the two pair in parallel to get around 400W of input. The Bluetti can accept up to 450W (the product description says up to 500W, but I have found that it maxes out at 450W). With a slight discount on Amazon, they are a good value.Edit 3/17/21: After having used these for several months now, I am more than pleased with how these panels are performing. Just a few days ago, in March with the sun still not at peak height, just one of the panels was pulling in 100 - 101W of energy at around 2:30 PM. On a sunny day, I am consistently getting 190 - 198W of output (according to my Bluetti EB1500 display) from both of these set up in series. My Bluetti AC50S says that it is getting 90 - 95W of input with just one panel attached (can't handle 2 panels in series or parallel as it is overvoltage or overcurrent for the AC50S). No looking at getting a HQST 190W panel so I can put it in series with one of my 100W panels.

Bought these in the past. I have 2kw installed. Decided to get 10 more. Arrived well packed. Installing them. they are not the same size even tho Amazon says these were purchased before. They are wider and longer than before. The cells are bigger as well. So because of this I'm giving 2 stars because my roof looks crappy now with the new panels 2 inches taller on top and 2 inches longer at the bottom. Installed in series for 36 volt inverter. These vary from 45 to 46.8 volts per set even on a sunny day the power isn't consistent like the older ones.Follow up. Even tho they're not the same size, they are putting out way more power, so will increase 2 to 4 stars. Wish they would have noted in description that these are new model or some way to let the consumer know. At 1000 watts of panels, I'm getting 1015 watts. Amazing!
