    Here, you have the short test of the ELEGEEK 10W 18V Semi-flexible transparent solar cell panel bought in Aliexpress.

    Product Details:
    Size – 440*190*5mm
    Model – SWR1018B
    Max. Power – 10W
    Max Voltage: 18V
    Max Current: 0.55A

    More information: https://www.aliexpress.com/item/ELEGEEK-10W-18V-Semi-flexible-Transparent-Solar-Cell-Panel-with-DC-Output-Crocodile-Clip-440-190mm/32712715422.html

    Conditions of the test:
    - No clouds
    - Temperature: 10°C

    Measured values:
    Voc (open-circuit voltage) = 22.5V
    Isc (short-circuit current) = 0.2A
    P = U*I
    P = 22.5*0.2
    P = 4.5W

    The power measured is more than two times less than it is mentioned into the item description.
