I have 4 of these panels and they are excellent for charging my 3000 watt power stations. I highly recommend them.

I need total of 10 solar arrays for 2000W.
I am a fan of Renogy but I've heard lot of CallSun bifacial panels are good so I ordered 2x200W to test it out. I am so Impressed with the result even without a reflector on Cloudy day at 1PM pulling 425W in series configuration. I definitely will buy more to complete my array. -

These are great. We’re off grid and with the battery and inverter we got from amazon it runs our tiny house for about 4,000. That’s including panel mounts and stakes for the wind. And Will Prowse approved!

I added these to my ground mount setup a few weeks ago, and they’ve been performing great. Even on partly cloudy days, they still pull in a solid amount of power, which really surprised me. Installation was easy, and the panels feel sturdy with top-notch build quality. The bifacial design seems to help capture extra light when the sun hits different angles. So far they’ve kept my batteries topped off every day, and I’m really happy with how efficient they are.
