BougeRV Bifacial 600 Watts 12BB Solar Panel, 23% Efficiency All Black Design Monocrystalline Technology Work with 12 Volts Charger for RV Camping Home Boat Marine Off-Grid (BIFACIAL 2PCS 300W)

Make sure to confirm your open voltage
Make sure all your numbers are right volts,amps etc.. and perhaps most importantly wires quality and size and fuse are correct(for any system). And these are great panels. No complaints

Delivered ok
I have not hooked them up yet, but the box was delivered on a amazon truck with no damage. They were packaged well and look like nice panels, I will be building a portable stand for them in the near future.Tried out today, had a mostly sunny day with a few brief clouds. I was only using one 300 watt panel for this test run. The max watts in that I noticed was 273 watts. Panel seemed to work fine with our homemade stand, and I am quite satisfied with today’s results.

“8th time’s the charm!” Trash quality, excellent in ideal conditions only, GARBAGE customer service.
*2 month update*- After shipping the wrong replacement panel BougeRV simply suggested “can I use it anyways” and claimed the issue was because their warehouse didn’t have any stock… except they’ve been consistently keeping Amazon stocked!- I never received a replacement, will reach out to Amazon soon to start an A-to-Z claim against them.- After ordering a total of EIGHT… EIGHT!!! panels I finally have 4 decent ones.- Don’t buy these based on the listed Voc and Ioc figures, they’re fake. Actual Voc is between 25.8v and 26.7v. Ioc can push a full 10amps, even at a solar irradiance of 820. Every panel I tested exceeded 8.8 amps open circuit, but none were even close to listed Voc.*1 month update*- BougeRV offered a replacement panel at no charge. Great!…the panel that arrived is substantially different and incompatible. Discovered they manufacture two different panels with identical part numbers. Yikes!- Ordered another pair. One panel is excellent, the other has a manufacturering defect – fractured cells. Voc tests low.- For reference, high quality residential panels (incl. Mission brand, which are a solid choice for mobile applications) can be easily found for ~$100 / 400w, so these priced significantly above $100 is a terrible deal.*2 week update*- Voc has degraded to 26.1v and 25.7v, and tested under more ideal conditions.- Lousy bypass diodes, shading any of the 16 BB’s results in a -50% drop in output.- Performance during cloudy days seems to be decent, but full shade on an otherwise clear, sunny day is abhorrent…output drops to ~5%.- “Customer service” continues to send nonsensical content and never answered any technical Q’s.*Review #1*Performed standard Voc test on arrival of (2) 200w panels. 27.3v and 26.7v, both a bit low, with the latter outside the manufacturer’s 5% tolerance. Contacted BougeRV about what a low Voc could indicate (panels visually look fine), but after 2 emails it became readily apparent the conversation would be going nowhere – all of “Samyi’s” responses completely ignored everything I previously wrote, including ample copy/paste material that wasn’t even applicable to the issue. Complete waste of time.Panels may perform well but don’t expect any customer service or technical support – you are on your own after the Amazon return period ends!!! “Warranty?” Forget about it!

Pricey but exceptional
300w+ in thick cloudy day
