CE517: Performance Modeling of PV Systems

NABCEP CE Hours:  3.5 hours (click for details). Estimating the production of PV systems is critical for their success. Modeling is required for any sort of financial calculations, as well as for back-testing system performance.  Furthermore, different system design architectures and equipment choices can easily be simulated and compared, which can lead to more efficient and better performing systems being installed.  Further NABCEP hours information found under Certification section below.


what you will learn

Modeling is a complicated topic – and performance calculation tools offer nearly endless “knobs” to turn, any of which can impact the projected production. A fundamental understanding of what goes on “behind the scenes” is important to be able to make the right decisions when selecting data, adjusting system assumptions and de-rates, and comparing results so you can be confident when you make a production prediction or design choice.  Don’t worry, the heavy math is left to the modeling tool!

Topics include:

  • Examining and applying the core calculations used to predict production of PV arrays
  • Comparing the various modeling programs on the market, and their different approaches (I wonder how current this is? – rw)
  • Interpreting simulation results from performance models
  • Relating how system design choices impact the production of the array

Join Paul Grana, co-founder of Folsom Labs and the HelioScope modeling and design tool, for an in-depth look at PV system performance modeling in four Parts:

  1. Introduction and System Design
  2. Environment Assumptions and Irradiance Calculations
  3. Module Modeling and System Behavior
  4. Simulation Results and Model Comparison
