Very good value in terms of getting the most for your dollar. Solar panels were almost flawless except for some of the frame edges being a little off, but that's to be expected for budget solar panels of this price point. I would buy them again.

I purchased this to accompany the first solar panel I have, and it works very well.

I was apprehensive to order these at first, but I'm glad I did.

These are an amazing deal for the quality they are! The listing is accurate!

My application was to mount 3 of them on my 36v golf cart and never have to plug it in to charge again. And I haven't had to plug it in for MONTHS! I used 3 on my golf cart roof and in full sun they are producing 45volts. On cloudy days it's 43volts. I often have to drape a towel over them because my golf cart won't let me drive it when it's recieving that high of a charge.

My husband used the remaining one in his workshop to run some lights and keep batteries charged.

Overall, amazing deal and quality product! Will definitely be converting more things to solar soon and will order these to do the job!

I have this HQST 100watt solar panel on the FrontRunner roof rack on the 4Runner. I have aluminum mounting brackets under this bolted to the roof rack. I've been on the highway over 80MPH and no problems. My vehicle lives outside and so far so good. I have a 10ft cable running inside charging a Jackery 240 battery. I went camping for a weekend and the panel kept enough power in the battery to power a cooler type frig in the back. We had a mix of sun and rain. Mounted flat on the roof is not ideal, but this is what I have. The jackery has a max charge ability of 60watts. Unless its super cloudy, It usually charged at 60. So, this panel is putting out at least that much mounted flat. I now use the jackery to charge other devises like phones and wireless guitar packs etc.. All sun power instead of a meter.

I bought these panels for two reasons: The price and the size. I have actually bought 16 of these panels - 4 different times I've purchased the 4-pack of 100 watt panels. They are nearly $100 cheaper for the 4-pack today than they were when I bought the first 4-pack. As of March 18, 2023 they are $274.99 for the 4-pack of 100 watt panels and there simply isn't a better deal for new panels than that anywhere.

The other thing that steered me towards these was the size. I wanted to be able to take these with me - at least a few of them - on the road if I needed to and as someone who doesn't own a truck or a van, these panels were the perfect size for being able to toss them in my car. And they are rather light weight, too, on a single panel basis at just over 13 pounds.

As for the panels themselves and how they work - they work great. During a clear day, at peak sun, I will get anywhere from 97% to 102% of the rated output of the panels. In order to get that kind of output you are going to need to dial in the angle of the panels, but if you do get it right you can get the full output with these.

The only "con" to these panels is that the MC4 cables are a little bit short. You have plenty of room to connect one panel to the other when they are next to each other, but compared to some other brands they are a bit shorter cables with less wiggle room for your potential set up. As noted though - you shouldn't have any issues connecting one to the other if they are next to each other. This "con" is very nitpicky, but it felt worth mentioning as not every person purchasing them will be mounting multiple panels that are touching each other.

If you are in the market for 100 watt panels then I would very highly recommend these.
