A solar panel is able to output 120 kJ of electrical energy for every 200 kJ of light energy that it collects from the Sun.

Calculate the efficiency of the solar panel.

Answer :

To calculate the efficiency of the solar panel, we need to understand the term 'efficiency,' which refers to how well an energy conversion process transforms input energy into useful output energy. Efficiency is expressed as a percentage and can be calculated using the formula:

[tex]\text{Efficiency} = \left(\frac{\text{Useful Output Energy}}{\text{Input Energy}}\right) \times 100\%[/tex]

In this scenario:

  1. Useful Output Energy is the electrical energy produced by the solar panel, which is given as 120 kJ.

  2. Input Energy is the light energy collected from the Sun, which is given as 200 kJ.

By substituting these values into the formula, we get:

[tex]\text{Efficiency} = \left(\frac{120 \text{ kJ}}{200 \text{ kJ}}\right) \times 100\%[/tex]

Simplifying this, we find:

[tex]\text{Efficiency} = \left(0.6\right) \times 100\% = 60\%[/tex]

So, the efficiency of the solar panel is 60%. This means that 60% of the light energy collected by the solar panel is converted into electrical energy, while the remaining 40% may be lost as heat or due to other inefficiencies.
