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%.
_____
<em>Additional comment</em>
With current (2021) technology, the best efficiency one can expect from a solar panel is in the neighborhood of 23%.
25.67*10^ is not in scientific notation. This is because for a number to be in scientific notation, the number before the decimal point must be between 1 and 9.
I hope this helps.
