Can this panel advertised power be real?

Hi guys, I’m looking to expand the solar instalation on my rv, so weight and space is a concern, I found this panles advertised at 200w each which size is only 1060 * 277 * 3 mm , previously I have installed other panes sized 1175 * 540 *3 mm rated at 100w (18v * 5.55a), so I am feeling very reluctant to believe this other finding which are shorter and narrower and are advertised to produce twice the power.
What do you think?

Doesn’t seem right to me either.

A standard 330W panel is 1.7m2, this is 0.3m2. It’s same efficiency, so it doesn’t add up to me :man_shrugging:t3:
