Features
- Bifacial Tech, Up to 15% Extra PowerDesigned 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 OutputMaximize 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% EfficiencyHQST 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 PerformanceHQST 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 InvestmentRated 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, its a smart, long-lasting investment for sustainable power.

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 -Lightweight Dislikes (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.

I'd originally given these a bad review. It was mid-November, and I'd hooked two of these flat to my van roof in parallel and was only getting 95 watts total at the very peak of sunlight in southern California. Not great. Well, what I noticed recently and over the past few months (it's now early March), is that every week, due to the changing of the sun's proximity to earth, there's been a noticeable uptick in wattage. I'm now getting 135 watts total (and sometimes 140, and twice lately even 150!) in full sun, and I definitely expect this to go up even more as the summer equinox gets closer. So, presently, I'm getting 65-70 watts a panel, laid FLAT, during peak hours, which is quite good (angled panels would be perform much much better than this)! I also notice that they perform much better in cloudy skies (and shade) than my previous cheaper Topsolar panels, which can be very advantageous when living in a van and experiencing several days of cloudy skies, enough on its own to not buy the cheapest panels around. I'll note that they are actually considerable bigger (by maybe 1/5 inches width-wise) than aforementioned other panels and others. Something to consider if space is super tight. I highly recommend these (and advise to nab them when they're on sale).

I wanted a portable solar panel to charge my Jackery Explorer 1000 V2. The price was great. Already a good deal at $100 compared to other 100w panels, I was able to get this on spring sale for $70. This comes with multiple connectors, including a DC7909 which will works with my older Jackery explorer 240. However, the Jackery Explorer 1000 V2 needs a DC8020 connector. I needed to get an adaptor (https://www.amazon.com/SinLoon-Adapter-Connector-Compatible-Explorer/dp/B0C6P6X5YP?ref_=ast_sto_dp) but everything works perfectly. It's solidly built, folds down to an easily portable size, and seemed to be charging the explorer well in the sun (70+W in the sun). Pleasantly surprised at how well this work so far.

For the price, It does keep my emergency battery running well, and it is easy for me to handle. It still to early for the five stars.

I planned on installing this on the roof of Polaris Ranger. I tested the one I received and it was a little low on output. So after I contacted the supplier they responded quickly and after I took a picture and what they needed, they quickly sent a replacement. Fantastic service from them and I will buy from them again. Every product has a problem sometimes. It’s what the company does that really shows its worth. This company did a great job. Thank You. Fantastic company! I installed the replacement easily on the Ranger. ( It was sent quickly from this company. ). So… After using this for a few weeks I’ve decided it is absolutely worth the money. It has been charging the spare big battery even in very low light of skylights in the shop. Perfect for the Ranger roof and very light weight and thin. That keeps it out of sight and no weight on the roof. I want to say Thank You to the company for fantastic service. Buy this panel….it is worth it.

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 didn’t involve me having to rig it myself (minor complaint).
