I have 4 of these panels and they are excellent for charging my 3000 watt power stations. I highly recommend them.
I'm very impressed! I used the two 200w panels to charge a 2000wh solar generator and got 418w of output. The bi-facial production is for real. I recommend Callsun solar panels!
Tested 2 panels on 3/21/26.In series hooked up to my Pecron E1000 these panels at one point registered an amazing 301Watts I plan on many more this year. Thanks, Tom& Sharon
Panel seems pretty decent but I don’t know why you refer to it as anti shade because shade definitely affects it. The panel frame is black aluminum and moving it you need thick gloves to keep from burning your hands because it gets hot in the sun. The panel was delivered with one corner damaged and the company wanted a plethora of photos taken and the box repacked with another photo to get a claim from the delivery company. It would have taken great effort on my part to do all
They requested, so I just accepted the panel “as is” to make things less cumbersome. I think overall it is a decent panel for a fair price especially if you can receive one undamaged.
Happy with the power output even on a cloudy or overcast day, unexpected. I have been playing with reflective surfaces behind the panels which really increasesHappy with the power output even on a cloudy or overcast day, unexpected. I have been playing with reflective surfaces behind the panels which really increases the power! Thank you so much I will keep playing!
I live in northern Wisconsin and we've had many cloudy days since I've put my panels out and they are charging my batteries much better than I expected. I'm very happy with them. A great panel at a great price! Thank you callsun!
Panels arrived in roughed up box that contained rips, hoes and torn flap. Typical from shipping/handling unnecessary roughness. But Callsun knows how to use form fitting, custom fit dense foam that's strategically placed as well as white sheet foam covering both front and back of each panel. I ordered a 2 pack of 200 watts.leaned them up, willy nilly, on a big garden cart. Did bot adjust for best angle. I got 401 watts to my Ecoflow in February!! Florida, clear blue day low70's temp. THESE ARE MY NEW GO TO 200W bifacial panels.
Wow — the Callsun 200-watt solar panel really impressed me! My first test results were unbelievable. It not only reached its rated wattage but at times even surpassed it. I had two panels connected in series to my EcoFlow Delta Classic around 11:00 a.m. on January 10, 2026, in Orlando, Florida, under partly cloudy skies. When the sun broke through, the two panels in series peaked at 438 watts — far beyond my expectations. An amazing product! I’d definitely recommend it over the Renogy 200-watt Shadow Flux panel.
EXCELLENT
Excellant preformance��200 watt rated and actually achieves max 190-200 watts reularly.. Recommend highly
THIS THING HAS THE POWA!!!!! lol no seriously tho it brings in more than the 2 100w panes i had if i didnt need MORE POWA!!!!!! Id sell the other panels and use just this one its crazy how much POWA!!!!! It gives you its seriously under rated so buy it while its still on sale, quality is great POWA!!!!! Output is amazing and price is decent the size is a bit bigger than my 100w panels but not by much easily fit where my old one was after adjusting the mounts, my only gripe is the cord length sucks ass i actually had to dig up old solar wire to add length until i get another spool of it to make it clean and all one wire each. Dont be a dummy buy this and save some money and make more POWA!!!!!!
I've tested a bunch of solar panels over the last year and this was the first one that I actually went and bought a second one because I liked it so much. It's a 200watt panel that is mostly black and they seam well together without that aluminum colored frame. Rated at almost 24 volts and 8.4 amps this panel will output some serious energy. I've got them now hooked up to 2 100ah 12v batteries with a MPPT solar controller set at 24v in and 12v out. In testing the one panel on a cold December day late in the afternoon, I was able to pull 60 watts - which was amazing due to the conditions. It's since been snowing and cloudy most of the time so I can't test the peak performance yet. Based on the performance of another known panel at the same time, this should output about 170 with ease.The shadow effect on this panel is much less than other panels I've tested. Since there is one tree in the way during a few months, this will be important. The frame is solid and has the standard holes for mounting. Good solder joints under the junction box. The price is a bit higher than some, but I still bought a second one because it tested well, looks great and the size is smaller. I also tested a 100 watt panel that did just as well from the same company. Two of these just take up less space and is easier to install 2 instead of 4.Overall: Yep, put these on your list. These are going to power up my workshop and I have no doubts about their ability or longevity.
Keep in mind product description states high wind resistance - impact resistance is the same as other solar panels. I had an issue with one of the 5 panels I bought and customer service was impeccable. Other than that, these panels output the rated power, or a little more in some perfect sunlight scenarios.I would buy again from this manufacturer /seller without hesitation.
I purchased two flat mounts for my fifth wheel RV roof. At this time, I only required enough solar to recharge my 12V house battery while the RV is in storage. Presently, it is really an oversized solar battery charger. I wanted the 200 W for both assured charging even on overcast days, but most importantly, for future use to top off my solar generator after I purchase a second panel. This panel is producing more juice than I expected, considering it is flat on the roof and we tend to get more clouds than sun this time of the year. On a sunny day, I easily achieved 190 watts, and on an overcast day, I still managed to pull over 25 watts. Lightweight and well-built. Happy so far.
Well so far I can only get like 28 watts from it . It's on a low roof and at about a 35 degree angle maybe 40 it was sunny out all day idk about this panel I will check it out more tomorrow I expected much much more out of it.not good so far so now the company got back to me told me a whole lot about how the set up I was doing and how solar works so I re did a couple of things I disconnected one of my other panels and now received 123 to 124 watts out of popcorn n panel so it was much better ?? so just to say the company was a big help on letting me know how their panels work and the whole solar thing so I would like to change my rating to a big plus and thank the company for getting back to me .thank you topcon for helping me with the issue.
When I opened the box I was hesitant to even go through the process of even connecting it as the packaging was subpar at best. I was expecting damage during shipping. Much to my surprise the solar panel not only worked, but worked great. That was, it worked great for 3 months and then quit work all together.UPDATE 3/21: Customer service is phenomenal. Even though the company didn't have to, they quickly sent a replacement panel. Hooked the panel up to my system and I'm back to generating power..
In case it's not clear from the pictures, there is a single solar panel in this. But holy smokes, that's a lot of energy for a single panel, especially when switching from polycrystalline. It's still new to me so I may update this depending on how well it holds up.
Fantastic solar panels, the best I've owned. I have a 1,000 watt Callsun array and it good conditions I consistently get in the mid 900 watts and on a few occasions for a few minutes at a time I exceed 1,000 watts. These look good (I much prefer the black) and they just work. I have them in a series array so with any kind of shade they do suffer a loss of power but that's to be expected.
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.
