Had up for about 1 week in Florida with panels in 24V series and appears to be be quality and very good even in light shade. Is well made and of quality materials. Will buy again when ready to expand.

  • Reliable 31 volt, 400 watt Solar Panel
Size: 400w Color: Black
I really like this solar panel. Provides 400 watts to power my boat batteries. One caution I should have known — you can’t charge a 48 volt system with a 31 volt solar panel. Actually, you can charge with an electronic item called a boost converter. I put it on a cart that sits next to my boat, while at the storage facility, see photo. ... show more

  • Great panels for the price, works great with ecoflow stream.
Size: 400w 2pcs Color: Black
Panels deliver around 300 watts the temperature has been in the 80s so the watts will be lower. Also I do not have them at the optimal angle. I have two hooked up to a ecoflow stream, I will have 4 hooked up when I mount them to my Shed. I'm happy with them. Easy set-up with the ecoflow stream, plug them in and plug the stream into the wall socket and your making power. In Utah you can have plug in solar up to 1200 Watts. I should have around 1200 Watts when I'm done. Panels always give you less than rated unless, they are cold and at the right angle. ... show more

  • I'm on my 6th one now :)
Size: 400w Color: Black
I love these. They are big but that's expected. Boy I can't wait till they get more efficient and smaller, but we know the fed gov stops that from occuring. Anyways, these work great and I'm almost at 3000w incoming.
