How can you claim to reach 160W with a surface of about 1/3 of m2 (74.8cm by 48.7cm, including the edges). As the sun produces 1000W/m2 in Switzerland and the efficiency of the cells is 21%-22%, this gives a maximum of (1000/3*.22) = 73W... Where is the bug?

Question

Answer

Um... the unfolded dimensions which are triple (157 x 68cm, i.e. a surface of approx. 1[m2]). With the edges, that's it... All good, then. See https://eu.ecoflow.com/products/160w-solar-panel
