Question
Standard solar panels transform 3,600,000 J of input light energy into 720,000 J of useful electrical energy. The new solar panels that mimic butterfly wings are thought to have double the energy efficiency.Calculate the energy efficiency of the new solar panel improved through biomimicry.
Solution
Step 1: Calculate the energy efficiency of the standard solar panels.
Energy efficiency is calculated by dividing the useful output energy by the total input energy, then multiplying by 100 to get a percentage.
For the standard solar panels, this would be:
(720,000 J / 3,600,000 J) * 100 = 20%
Step 2: Calculate the energy efficiency of the new solar panels.
The new solar panels are said to have double the energy efficiency of the standard panels. Therefore, their energy efficiency would be:
2 * 20% = 40%
So, the energy efficiency of the new solar panels that mimic butterfly wings is 40%.
