Product description
1 Get More Energy
2 Grade A+ Cells
3 Better PERC Cells
【Bifacial Tech, Up to 15% Extra Power】- Designed with advanced bifacial technology, HQST 100W Solar Panels capture direct sunlight on the front and reflected sunlight (albedo) on the rear. The result? Up to 15% more energy output than traditional panels, delivering up to 115W of power from a 100W panel. Maximize your solar potential with HQST!
【Installation Tips for Maximum Power Output】- Maximize energy output by installing bifacial solar panels on reflective surfaces or mounting them above the ground to capture more rear-side sunlight. For optimal results, set the solar panels at an angle between 20° and 45° in highly reflective areas like snow, cement, sand, grass, or white surfaces.
【Grade A+ Cells, Up to 25% Efficiency】- HQST 100W 12V solar panels feature advanced Grade A+ 9-busbar solar cells, rigorously tested with EL technology to ensure zero cracks. With an outstanding conversion rate of up to 25%, they outperform traditional panels and deliver better performance.
【Enhanced Low-Light Performance】- HQST solar panels utilize advanced PERC solar cell technology to maximize energy conversion. By reflecting unused sunlight back into the cell, PERC cells capture more light, including low-energy infrared, making them highly efficient in cloudy or low-light conditions. Built-in bypass diodes prevent overheating and ensure the panels continue performing even when partially shaded.
【Built to Last, A Smart Investment】- Rated IP68 for dust and water resistance, this 100W solar panel is built to withstand dirt, splashes, and rain with ease. Its anti-corrosion aluminum alloy frame ensures decades of outdoor reliability. Engineered to handle extreme conditions, it boasts 2400 Pa wind resistance and 5400 Pa snow load capacity. Delivering powerful energy output for up to 30 years, it’s a smart, long-lasting investment for sustainable power.
Customers say
Customers find the solar panel works well, with one noting it performs even with shade, and produces 85 watts in full sun tests. Moreover, they appreciate its solid construction and consider it a good investment, with one mentioning it stands up nicely. Additionally, the panel is easy to install, with one customer noting it can be mounted with just 6 screws, and provides sufficient power to charge batteries. However, the wiring receives mixed feedback, with some praising the standard connectors while others report issues.

Works great, especially for the price
Used this on 2 different units (Ecoflow and Bluetti) and love the universal cord that’s included. I didn’t have to dig through my bag looking for the right cord to use. I tried this at 2 different times in the day in 2 different locations and both units were getting between 60-70 watts of charging power . There was clouds in the sky and I didn’t spend a lot of times adjusting the position of the solar panel to try and dial in the sun to get more watts. I was pleased with the 60-70 watts with just setting it up, especially for the price paid (was on sale for like $70). I would definitely buy this solar panel again and will look at larger wattage panels from HQST in the future.Likes:-The included universal cord-Price-Getting 60-70 watts without any detailed positioning (just setting it up and going)-Attached bag that holds and protects the cords-LightweightDislikes (or improvements):-Small complaint, but wish the bag’s zipper opened the other way. I set the panel up and then went to pull out the cords and the zipper was towards the bottom. Again, not a deal breaker and a very minor complaint. Would have just been easier to get out the cables if the zipper started at the other end.-Wish they would move the bag where the charging cable is to another panel and put a kickstand on the last panel or may help to have 3 kickstands. Again, minor complaint and would not prevent me from buying it again.

So far so great! Prefect for my DIY project.
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!

IS compatible to charge Bluetti EB3A, may need adapter
Update: After getting an adapter, I was able to get this solar panel to charge my Bluetti battery. A little ridiculous I needed an adapter because they are essentially the same, but the one that came with the panel was not staying in the battery input. The panel is facing south/full sun and at noon has an input of 53 Watts. We will see how long it takes to charge it to full capacity. Just happy it works!I purchased this along with a Bluetti EB3A 600W 268Wh battery in hopes I could charge the battery with the solar panel in case of emergencies/power outages.While the solar panel works and the battery works, the 4 in 1 charging port included in this solar panel is not compatible with the input for the battery.I am now trying to find a way to make them compatible which is a pain since Amazon and the many resources I looked at before purchase said they were compatible.The only other complaint I have about this solar panel is that the stands it comes with are rather flimsy and I wish it had other options for attachment that didnât involve me having to rig it myself (minor complaint).

Great Power at Affordable Price!
Bought these for our eco flow.In case of emergency.I had an older panel of this same brand and it worked really well. After purchasing one of those foldable solar panels 200 W. And only getting 85 I decided to go back to these glass panels. They might be a little bit more bulky but in an emergency, it’d be perfectly fine. I only set them up against my patio chairs to test them. They’re not that heavy really. About 10-12 pounds apiece. I’m very happy with the results 187 W they were pulling in at approximately 11:30 AM. I had two 100 W panels connected so I’m very happy with 187.watts. I highly recommend this brand. I believe they make a good quality product.I liked them so much I bought 2 more.was getting 101 watts from one 100 watt panel! Cant do better than that ! Five stars for these!

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.

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
