400W N型 16BB 両面ソーラーパネル 200ワット 2個

Nothing but praise for these solar panels. I have a bluetti system, with an adapter to add additional solar power to the AC input. That adapter is limited by a 10-amp, 500 watt max capacity, and I bought these solar panels because they stay within that limitation, but provide the most watts. They are well-made, and worth the money. I have other brands of solar panels that generally pull 80-90% of their rated capacity under the best of conditions. These panels are rated at 200 watts each, and at times, I've seen the pair pulling 420 watts. That is outstanding! They work even better than advertised. They are a bit heavy (which isn't a bad thing at all - a sign of quality build!), but are still manageable and easily mounted. Overall, I am very happy with these panels, and will likely be buying more. Highly recommended.

All panels have the same great output. My first shipment of two, 200 watt panels had six holes in the and a large gash in the box. FedEx photographed the badly damaged box but said if I opened it to inspect the panels, he would not be able to take them back, even if they were damaged. He left them with me and left. I opened the box and both panels were fine. They had very strong corner plus end and side protection. I order a single 200 watt panel and it also arrived in perfect condition. Great job Callsun. I really need another panel and I will buy from Calsun again.

Currently have 2 in series. Going to 3s2p eventually. I seriously doubted claims of 400 watts (especially by reviewers who submitted in early January). The sun isn't strong enough in Alabama (at least) during the winter to get that. I installed these initially in late December and was maxing out around 230 watts in full sun at proper angle. After the winter solstice things have gotten muuuch better. I'm getting around 340 now. I expect it to continue to rise as the sun "gets stronger." I replaced a single Dokio 400 watt panel with these 2 - 200 watters. I prefer these as they are lighter and smaller and easier to move around than a 400 watt panel. They are sturdy and I don't worry about the frame bending or breaking. i have zero issues with these and will purchase 4 more. I can get about 1.7 Kwh in a day right now. I'm hopeful I can get that REALLY close to 2 (per pair). That would be ideal for my 4 - 200 ah battreez.My only qualm is that the cables are a bit short but thats splitting hairs.Update. I Implemented my other 400 watt panel in a different power system. it's orientated in the same direction with the same angle but it vastly underperforms these. Granted, the others aren't bifacial and are 12bb vs 16 but I didn't expect such a big difference. The top Victron connect is the one hooked to the Dokio. the other is the 2 - 200 watt panels. and that must have been during some shadows as it hit 356 that same day. and it has hit 393.update - I finally got around to going 2s2p at least. I pulled 811 watts on those four panels. in April. So I'm beyond happy with that.my 400w dokio panel has yet to break 230.update - pulled 986 on 800 watts worth of panels. bifacial is for real. you can expect a 25% boost in optimal conditions. on these at least. want 1 more pair and I should be able to run my mini split pretty much fulltime. great panels. can't recommend enough.Update and previous correction... I didn't realize it at the time but colder weather is better for peak performance. meaning your incoming watts will be higher on a cold day than a hot day. but you'll get more overall power on a hot (summer) day due to the sun being in the sky longer. As such I never beat that 986 watts during the summer. in fact, I don't believe I got above 800. but I don't spend much time there in the summer so not a lot of opportunities to bulk charge. Still extremely happy with these and would highly recommend.

These panels are perfect for small installations and come packaged really well. They should give other companies classes on how to ship solar panelsThe performance is great as well. Getting full wattage at peak times of the days and over on cooler days.

Maximum Fuse Series Rating: 15ASo far I have no complaints. 4 out of the 6 units ordered arrived on time and undamaged. I got the remaining 2 boxes a couple days later after speaking to Amazon. I'll be posting a review with more details after I unbox and setup the remaining panels.I wanted to get this information out first because this isn't included on the product page �� not here or on the datasheet. The max fuse in series needs to be 15 amps, not 20 amps, not 25. 15A. That's a happy coincidence since I had already bought a 5 pack of 15A inline fuses from BougeRV (separate review to follow later).Included is a photo of the manual with helpful details. Take note that the colder your panels stay, the more power you'll see coming down the line, mostly in slightly higher voltage. That can be a good thing if you account for it, and these panels work as cold as -40�� C/F.Preliminary testing with almost no load showed around 300W of power generated from a 200W panel with temperature around 80�� F. That performance is excellent, however I need to check it with a load present and longer sun exposure to heat up the cells.Unboxing the solar panels is better with 2 people. With a box cutter and a large flat area to lay down each panel, a single person can manage just fine. I didn't even use a utility knife; just opened the folds on the top lid and tore one of the sides open. If you do that, just be mindful of the thick staples. Using a workbench around 5 feet, they're pretty easy to move around. However, my bench is pretty cluttered so I've been laying them down in pairs on the ground with some cardboard and a large moving blanket as padding. Lifting two at the same time from ground level is a pain. But compared to larger P-type panels or 400W panels in general, these are a welcomed relief. Just move one at a time. That's a nice benefit of going with 2x 200W panels instead of huge 400W panels.Expect an updated review in October with more details and photos.
