HQST 4PCS 9BB Cell 100W Solar Panel 12V 400 Watt Monocrystalline Solar Panels High-Efficiency Module for RVs Motorhomes Cabins Marine Boat Off-Grid

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.

great panels, put out their intended amount of power, anyone complaining otherwise doesnt understand solar energy or electric. bought 8 of these and 2 were having some bubbling in panel.. there is a 5 year guarantee against defects and i emailed them, sent photos, and they offered new panels or refund with no problem... excellent service and kept warranty promise... hard to find these days... i saw other customer complaint about this issue where he says he is out the money, he never contacted seller....

Panels are installed and we’ve been using them for a few months now. They are well built and have good output. I have a renolgy system and these panels may be better built and can’t tell a difference in output.I’m currently using them in a series connection to power a small 24v system at an off grid cabin. They consistently produce 40+ volts on sunny days to my charge controller. Even when it’s cloudy and not much sun I’m running in the mid 30volts. I will be purchasing more of these.

I purchased the HQST panel primarily for price. I have heard and can now verify that the build of the HQST is identical to Renogy 100w monocrystalline panels. The MC4 connectors are even labelled as such.Overall the packaging was okay. It came in the original cardboard box. The panel had foam corner pieces to offer bump protection during shipping. This can lead to possible damage should the delivery person be rough with the parcel. My package came undamaged and the panel was intact.As for build quality, everything is looking good. I have had various foldable panels in the past as well as home solar. The panel itself appears high quality. The panel is appropriately fitted to the aluminum frame. Everything is sealed as it should be. The transformer box is also intact with appropriate crimps. There is ample sealant on the box to prevent water damage as well.My only "do better" would be to have more mounting holes in the panel. The predrilled holes are on the long side of the panel.For my specific use, I wanted a panel I could mount on my pop up camper that would survive. I have not heard the best reviews of the flexible panels for durability. This HQST panel feels very durable. I will be sure to return and update the review should problems arise. The panel is true to its weight at just under 15 pounds.Solar panels are a bit tricky to test throughput. There are plenty of variables with angle, sun, temperature, and so forth. I was unable to get the full 100watts out of the panel (ran mostly in the 80watt range). This is consistent with reviews found elsewhere. Just keep that in mind if you are expecting full power. monocrystalline is also limited on its output under shaded conditions so try to get full sun!Overall, I feel this is a great product for the price. I paid $80 and it is essentially identical as the Renogy panel that is $100-115. I will be buying more HQST in the future! I hope this helps your decision.

These panels did 90.5 percent of rated watts. capturing lots of solar power right out the box with temp setup. Very pleased at this time with purchase. I reccommend these panels. They look good, work as expected. i will try and add pics and maybe video when i get them fully set up. Today they where just propted on a box at near as possible angel.... they were not perfectly set up....but still did the job.... i ran a box fan all day while still charging batteries off of these.

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!

Leider handelt es sich nicht um ein Panel wie auf dem Foto zu sehen, sondern es ist ein Panel auf einer Plastikscheibe und es ist somit flexibel

Entregado el día correcto,espero que vaya bien, pues ya he colocado otra como está y va perfectamente, así que e😋Ya la he probado y funciona perfectamente de momento muy contento con la placa.

C'est le dixième module que je commande. Rien à redire, livraison sans problème en 48H, bien emballé. Il est donné pour 100W. C'est la théorie, face au soleil (1H avant et 1H après ça décroit) sans nuage, atmosphère claire d'été sec. Face au soleil ça veut dire perpendiculaire, quelle que soit la saison et l'heure. A plat sur le toit d'un camping car l'hiver, ça sort 10 watts. On y peut rien, c'est normal. Donc ne pas réver. J'ai 12 panneaux, pour ma pompe de piscine, ça va l'été de 11H du mat à 15 Heures. Après c'est 1/4 de temps grâce aux batteries. Ce panneau seul ne suffit pas. Achetez en plusieurs. Un micro-ondes prend 750 watts. Donc tenant compte des pertes, il doit charger la batterie 2 heures pour cuire des patates pendant 10 minutes. Mais c'est un panneau au top pour la technologie 2018.

Grazie Amazon per la velocità di spedizione e pacco integro in tutte le sue parti.La recensione è ottima su questo pannello e lo consiglio a coloro che vorranno acquistarlo.Appena montato sul Camper ha cominciato a lavorare nel migliore dei modi. Soddisfatto in pieno.

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.
