Lesson 6 Scenario

You work as a solar system designer for a solar company. You have two potential clients who want to install PV systems. The first client is interested in a grid-connected system while the other wants an off-grid system. After reviewing data collected by the sales representative from the site, your task is to accurately size these systems.

What do you look for when deciding the system size in regards to the load demand? Is there a difference between grid-connected and off-grid PV system design? What are the steps to designing each system?

In this lesson, we will find answers to these questions and we will discuss topics ranging from load analysis to PV system design. This lesson prepares solar professionals to become PV system designers. Sizing PV systems is similar to art, where using the right tools ensures the PV system is sized to function properly.

Learning Outcomes

At the successful completion of this lesson, students should be able to:

  • Compare sizing strategies and methodologies for different PV system types.
  • List factors that affect sizing a PV system.
  • Calculate load requirements for different PV system types.
  • Apply tools for sizing grid-connected and stand-alone PV systems.
