    Answer:

      48.6%

    Step-by-step explanation:

    Efficiency of energy conversion is the quotient of output energy and input energy.

      (3291 J)/(6771 J) × 100% ≈ 48.6%

    The solar panel’s conversion efficiency is about 48.6%.

    _____

    Additional comment

    With current (2021) technology, the best efficiency one can expect from a solar panel is in the neighborhood of 23%.
