HQST-100W 12V Monocrystalline Solar Panel, High Efficiency Module PV Power for Battery Charging Boat, Caravan, RV and Any Other Off Grid Applications(2-Pack Solar Panels)

These things are freakin awesome! I get over 100 watts at peak solar gain hours, and they have proven to be tough as nails. Had a 6' step ladder fall on them, but nithing broke. Also had the wind rip them off a temporary/portable mount, and fling them on top of each other, with no damage. Forget flexible panels, and figure out how to mount these units on your van, RV, or boat, if you just need a small system. I am running three of these, through a cheap (Renogy) PWM charge controller, and feeding into a 100ah lifepo battery. Runs my fridge, charges all my devices, cordless tools, fans, and anything else I need. Excellent product. Excellent value.

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.

Works great. I purchased my second one and together they are giving me over 10 amps of power. Bifacial is working great.

I purchased this solar panel because it was an awesome price. When I received and opened it I found that it seemed to be a good quality product but to my dismay it didn’t have any mounting brackets or extra wiring. Be sure to carefully read the product description because not all cheap deals are good deals.

Great 200w Solar panel. Very light weight, but seems durable. Rather than installing 2 100w panels, this is lighter and smaller in size than 2 100w; and doesn't require a Y connection, which loses power. Haven't guaged the output yet, but seems to work well with my Hqst MPPT controller. Charges my Eco-worthy 280ah LifePo4 up very quickly. Oh, added bonus, the black looks very cool on the roof. Now, for the Negative, packaging was extremely poor. I am surprised it made it in one piece. only 2 edges had protective plastic pieces, only a thin piece of padding between the glass and the box. I give all the credit of it arriving in 1 piece to the UPS people!! Not much use for the Bi-facial panel as it sits on my camper roof and might only get a bit of extra.

So far so great! For the price you will not do better. These are double sided (in short on the back side they capture reflected light and boost the overall output. I am getting well over 100 watt on these 100 watt panels). I am not sure how long they can maintain such a low price, however, one panel is a great price and two panels bought together is over the top amazing. Super simple standard connectors and if you need straight wire connections the wire quality is great for stripping and utilizing (this most likely voids warranty, with that I can see no reason why you would need to use the warranty as the panels are solid and well built. As for the double sided feature, the concept calls for the panels to be mounted off the surface so that reflected sun light can hit the underside. So if your brackets are up allowing light to get underneath these are for you. You do need a controller, pick a good one. PWM controllers are not as efficient as MPPT. You pay more for MPPT and it is well worth it (look for deals). In my specific DIY application I am doing a 360 degree rotational rig so that the panels are always facing the sun. For seasonal adjustments I will set the pitch (or seasonal angle manually 4 times per year, i.e. Summer Winter solstice and spring and fall equinox). ~20 degrees to about ~40 degrees towards equator). I am using a slow high torque motor and a timer (motor speed .6 RPM the timer is on 4.17 seconds every hour). A slip ring keeps the power line from twisting. Fun little project.... Be well!

Worked as expected for a small battery power station. My 1st experience with a solar panel. It is a rabbit hole that once you go down the money you spend is endless.

Very good quality... Connects and provide the right amount of power

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.

We needed to replace a panel on our narrowboat and this product fits perfectly and works very well alongside the existing panel. The order was delivered next day and I was impressed with HQST service.

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.

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
