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

The panel is heavier than I expected (not by much), which I hope is indicative of its durability. I haven't had a chance to test the charging speed of it yet as I bought it for a solar generator I'd previously purchased and charged fully via 110AC. I'm optimistic though.

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.

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'd give 5 stars but the packaging was not that great but they were really cheap so it maakes sensevery pleased so farBeat the heck out of eco worthynot the greatest packaged but arrived undamagedI applied mylar to the back of the 4 panels I got and even though it's end of may and june is another day away when the clouds have cleared and it's the brightest from 1pm to roughly 4 pm I have achieved 110 watts a panel , the bifacial 4 panels I got also out perform the 5 other panels I have on cloudy days by sometimes up to 25% which really shocked me , the other 5 are eco worthy and arent bifacial so bifacial is the only kind i'll get now as it's mostly cloudy in the PNW this time of yearWhen there are no clouds my 4 bifacial panels get the fan on my 1000 watt grid tie inverter running very loudly and both sats of panels do thisHave only had them up for a couple months and my first regular panels cut my power bill by 35% so am very much waiting on my next bill to see the difference as my first set should even be an improvement as I had a bad connector and didn't notice for at least a week as I was working so much overtime that month I didn't have much chance to see them operating during sunlight hoursOverall VERY impressed with hqst as head to head the only thing eco worthy beat them on was packaging quality , I would have to give hqst a 5 star rating and hopefully the best is yet to come , the only downside is the bifacial panels create the tiniest amount of power in the dusk hours as they should but my wired meter most times has to be disconnected from the system and the system being completely re started for them to read voltage again correctly , sometimes they kick back on properly but not alwaysThat's on the cheap 150 amp meters and not the panels but THEY DO WORK WELLI got them when they were on sale for $59 and expect after summer the price will drop again so I will by more then as I have no real complaints and when weather cooperates they outperform expectations so for that they get 5 stars , washington sunlight negative 3 stars but at the price they will pay for themselves in 3 to 4 months including the grid tie inverter and wiring so great deal and hope tarriffs don't make em harder to get down the road

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).

This is of superior quality.

Good
