The inexpensive HQST 12v 100w Solar Panels outperformed the Renogy 12v 100w panels on Sunny days, but the Renogy produced more power on cloudy days, that is, in low light conditions: see the stats below.
HQST (4 panels) Renogy (6 panels) both use Renogy Wnd 30
Total Watts/day 1532 / 4 = 383w/p 1810 / 6 = 301w/p Sun May 2
Watts per Panael W/p
517 / 4 = 130w/p 863 / 6 = 144w/p Mon May 3
313 / 4 = 78w/p 414/ 6 = 69w/p tues may 4
300 / 4 = 75w/p 700 / 6 = 117w/p Wed may 5
1368 / 4 = 342w/p 1850 /6 = 308w/p thur may 6
fri may 7: 1760w/4p= 440w/p HqST
2067w/6p= 344w/p renogy
sat may 8: 1733w/4p= 433w/p hqst
2006w/6p= 334w/p renogy
sun may 9: same as sat
mon may 10: 1280w/4p= 320w/p hqst
1750w/6= 292w/p renogy
The test conditions were not perfect.
I placed two strings of panels next to each other (4 HQST, 6 Renogy)
each controlled by a Renogy Wanderer 30amp pwm controller; panels in parallel
i recorded the watts registered by the Wanderer Controller each day.
I live 30 minutes south of Chicago and I’m lucky to get 60wats peak from a panel
& a lot of trees around

HQST 9BB Cell 100W Solar Pane (Monocrystalline) – Used to maintain the LiFePO4 battery in a River-2 battery box. Horizontal under cloudless sun delivered measured 85 watts at the end of a long cable. When a cloud came along, still delivered about 25 watts. Were it lighter, it would be more easy to change its angle with the sun during the day. Came in an excellent box – open with care and save the end spacers. Expect to use the panel only only once a year as part of an emergency prep activity and the shipping box is ideal for storage.
For long term use, the glass covering should provide longer life and is probably why it seems heavy.
Jesse Salinas –
Nice and solidly built. I’ve not seen them deliver their rated power, but due to space limitations they are not optimally oriented towards the Sun and it is Britain, after all!
Amazon Customer –
This panel is absolutely as expected…Appears well made and delivers plenty of current even in less than ideal sunlight situations.
Pretty much the only negative is that the frame has no slot or hole for the wires so if you are mounting on a flat, solid surface, the wires *have* to exit under the actual panel.

Used these panels to replace panels damaged by hail.

This is second set of hqst 100 watt panels I have bought these are smaller than other ones I bought seems like good panel like my first set which are great
Jesse Salinas –
works, had expected more output but this is my first attempt at off grid power for my greenhouse.

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.
Daniel Steer –
works well but every other one I have seen has something to show which wire is positive, there is no indication and no notes.
Manuel –
The quality in these panels is high and obvious. Enough to warrant 5 stars, even though the kit is sparse: only the 4 panels and 1 piece of paper explaining how to properly wire them in are in the box. I highly recommend taking additional measures to waterproof the terminals on the back of each panel. Adding a spread of dielectric grease to the rubber ring seal on the snap-lid of the terminal box should be sufficient to ward off moisture for the life of these panels.
I highly recommend these solar panels, the price is very fair and the quality is on par with panels priced much higher. To complete this installation you will need to purchase additionally:
12 ga. wire and connectors
6 ga. wire and connectors
MPPT or PWM charge controller
Minimum of 200Ah worth of 12vdc batteries
12vdc to 110vac Pure Sine Wave Inverter

Keeps batteries charged even on cloudy days

I love this 100 watt solar panel the size it’s perfect, very well protected I am so happy thank you HQST
Mr Julian Angell –
Good quality..well finished..very happy for the price..will test shortly as basis for larger installation.
