Hello everyone,
I am encountering an error when using Sandia Photovoltaics Module version 0.0.68, which is preventing the photovoltaic surface calculation from proceeding. The error message is: “1. Solution exception:negative number cannot be raised to fraction”.
I’m not sure why this is happening. Some parameters of the photovoltaic module in the Sandia model, such as the temperature coefficient, are usually negative values, which seems to contradict the error message. Could someone please advise on what might be causing this issue?
I am using the Sandia file
Sandia Modules.zip (20.7 KB)

Thank you for your assistance!
