Multiple Module Power Classes in a Single Simulation

PVcase Yield now lets you simulate a layout that combines multiple module power classes in a single simulation - without splitting the project into separate files, simulating each part individually, and recombining results outside the tool.

Most real-world PV designs use a mix of module types, often due to supply constraints or design optimization within available space. Previously, capturing this in Yield required workarounds. With this release, a layout containing more than one module type can have the appropriate component assigned to each module type and be simulated together in a single run.

This first release supports layouts without an electrical design (i.e., layouts where electrical design is defined manually or targeted to a metric in Yield, rather than imported from a full electrical export).

What changed:

Layouts & electrical page

When a layout containing multiple module power classes is exported from PVcase Ground Mount, Yield now allows you to manually define the distinct module types. You can create and configure separate module slots to represent the different power classes used in your design.

• In the Module power classes section, you can add multiple module types (e.g., Module A, Module B) and manually input the module count for each, ensuring your layout is accurately represented before assigning components. 

• The Modules column now lets you assign a module component to each module type in the layout — for example, Module A and Module B — rather than assigning a single module to the whole layout.

• Each module slot is assigned independently, using any of the existing component assignment methods (from PAN file, from library, or manual definition).

Running the simulation

Once all module slots are assigned, you can launch a single simulation to assess the plant's combined performance and analyze the results as you would for any other layout.

Results page & PDF report

The Detailed Results view and PDF report now reflect each module power class present in the simulation, so you can review how the combined plant performs across the different module types.

We believe these enhancements will significantly improve your simulation experience and provide more robust options for modeling and analysis.
