Chapter 2

Trade Math for PV—Measurements, Units, and Calculations

2.1 Introduction

Students taking a lecture/laboratory sequence in photovoltaics need basic measurement skills and an understanding of the metric system (a/k/a International System of Units [SI]). Measurements found in PV vary from physical (e.g., length, area, and weight) and electrical (e.g., voltage, charge, current, power, and energy) to solar (e.g., irradiance and insolation). Students should also understand exponential notation, powers of ten, simple algebraic equations in a single unknown, and trigonometry of right triangles.

In this course we will cover these topical areas in the context of the tasks that solar design and installation require. These tasks include customer ...
