This item was difficult to install on a ECO-Worthy single-axis solar panel tracking system. The 4 panels side by side are too long even when then the metal bars on the axis are fully extended. The power out does not come close to 400 watts and the maximum power out so far is 220 watts as I write @ 12.30 pm. I am not happy as it falls short of expectations since there is another model installed beside it that give up to 470 watts.

I can confirm that these are true100w panels. it is not unusual to see them reach more than 220W together. Excellent products.

I ordered (4) of these panels. I am shocked. I was figuring having these set up in series parallel to keep the voltage under 60v I would maybe pull in 300-350 watts max. Well I just set them up temporarily to my EcoFlow delta 2 and I am pulling a constant 418-420 watts @ 43v. I think I will get (4) more. Maybe I got lucky but I would recommend these panels.Update 4/24/25 so I ended up ordering two more of these. I have a total of 6 panels in series parallel all in strings of two. It maxes out my charging on the ecoflow delta 2 500 watts in direct sun so that thing charges in no time. I also have a anker solix c1000 I saw this hit the max charging also of 600 watts. When I have time I will do a video. I am not a big review person but these deserve it.

This is the third Calsun solar panel I've tested and I've liked them all. This is not bifacial so it doesn't pick up reflected light on the back so it's just a little bit less effective in my setups overall. I usually turn them upside down to test that and this was black white on the back. Considering the price point I wasn't really surprised. It's an aluminum frame in natural metal color. It comes with the standard MC4 connectors and they are a good gauge of wire and the internal connections are fine.Setting this up in the late afternoon in PA in March, I didn't expect any great numbers so I had to compare it to others at the same time. I was getting 60-64 watts on this panel and slightly less on one other panel and slightly more on the other panel. So this works just as well as my best 100 watt panels ( I have mostly 200 watt panels these days ). I tested it with a 250 WH portable solar generator.So, if you're starting out into solar and trying things out, this is a great panel to test, add and keep. At $79 dollars with a $20 coupon, it's fantastic. I wish I could have bought these size panels when I was starting out at this price.

These are true 100w panels that will in fact produce the rated wattage unlike eco-worthy 100w panels that will only reach a max of 75w. They are well built and taller than the eco-worthy panels as well.
