These must be the latest "Chinese Watts". The V and A figures wouldn't even get 40 Watts.

1 Sol = 1000w/m2 so that panel size (which is gross, including frame) sees 117.6 Watts. Allow their generous 24% efficiency and the panel would produce 28.2 Watts @ 25C panel temp.

Just saying.

You shouldn't advertise that system so others can see it. Chris Bowen will be onto it straight away with 400W on such a small panel. He will have them stuck all over the Tesla we all bought him!

Hi qldcamper,

These sound too good to be true. At 740 gms in weight, they sound like a “flexible” panel. How is the heat that they generate being dissipated? Do they need an air gap under them?

A photo or link to a website would be helpful.
