HQST Bifacial 100 Watt 12V Solar Panel, 9BB Monocrystalline Solar Panels with 25% High Efficiency Module PV Power for Battery Charging Boat, Caravan and Other Off Grid Applications

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.

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! 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!

Tried this panel with my eb3a bluetti and i found it worked great and got 75 watts in full sun at 1:00pm i didn’t try too hard to get the max sun. It does appear that if you have 3/4 panels pointing to the sun on my car dash the eb3a bluetti would not register charge but if all panels were exposed to sun because the length doesn’t fit my dash that it would show 20 watts of charge coming in.Overall all not a bad budget panel, tad flimsy and if it was windy… not sure it would hold up too well in a breeze is my prediction without anchoring it.

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!

This solar panel works great! It arrived undamaged! Very portable and has plugs to fit most of the popular power stations! Works very well!

I placed this panel on a room at 7:30pm with no sun seen (still light) and it charged my security camera (Arlo pro2) to 5 percent on 40 minutes!!!Setup was very simple, it comes with M4 connectors (positive and negative), i ordered connectors separately and connected then to power controller ($10) and camera to controller via usb
