Wikipedia says… Calculus is the study of change, in the same way that

geometry is the study of shape and algebra is the study of operations

and their application to solving equations.

What is the big “change” in solar PV?

• Energy production from a solar module

So where is it useful to understand calculus?

1. Determining the optimal positioning of a solar panel

2. Calculating the total amount of energy a solar panel produces

3. Comparing different types of solar technologies

Calculus: What is it and where is it useful?
