How to compare two types of solar pv system

Dear all please inform me ,how to compare any two types of solar pv systems, such as Sandia PV Array model vs CEC Performance model.

One way to do the comparison would be to set up one case for the system that uses the Sandia model, duplicate it to create a second case, and change the module model in the second case to the CEC model. Then, after running simulations for each case, you can compare inputs and results by switching between the tabs.

You can read about cases in Help, under Getting Started, Manage Cases.

The Case Compare tool may come in handy too. It's on the Tools menu, and also described in Help (click the Help button from the Case Compare window).

Best regards,
Paul.
