Solar Panel 400Watt Monocrystalline 22 Percent Efficient Half-Cut PV Cells Off-grid Hybrid Motor Homes Caravans

I get power even when it's cloudy 30 watts in full sun 300 plus

Large, heavy panels, but do work well.Have them in garden and when sun shines work better than other panels I have.

This is great, bought one to charge my Eco flow portable power stations, then bought a second one, in summer in the direct sunlight they input around 330w for me on average, on cloudy days they pull about 30w,

Packaging was not great , would suggest checking fully on arrival. Panles seem to work very well but large for just four mounting positions, I had to run an additional support across the middle.

Runs my 65inch TV and shed plus tools (of course not all at once) Can watch TV all day and evening on the 2x100ah lithium batteries this is charging

I have 2 of these panels and no complaints about there performance here, even on cloudy days the output power is impressive, however the frames are of the same type and size as used on many much smaller 100 watt panels but on these much bigger and heavier panels its just not rigid enough so installation is very worrying, recommend fitting inside a very sturdy second frame first then placing them in their new home position, any tewisting of the panel during installation will easily end in shattered glass and the frames they are fitte with are just not man enough for the job IMO
