CE517: Performance Modeling of PV Systems

NABCEP CE Hours: 3.5 JTA/Other.  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, better performing systems being installed.


what you will learn

It’s 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 that you can be confident when you make a production prediction or design choice.  And 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
• 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
