Peak vs. Off-Peak energy production

Hello,

When you post questions on the forum, please provide more information about your analysis. It is helpful for me to know what performance model (flat plate PV, physical trough, etc) and financial model (residential, commercial, single owner, etc.) you are working with. Because there are many different possibilities in SAM, I can't always tell what you might be describing without that information.

I think you might be referring to time-of-use rates for either the residential or commercial financial model. Unfortunately, SAM does not report results by time-of-use period. For example, if you defined the peak period on the Utility Rate page as Period 1, SAM does not show Period 1 totals in the results.

Best regards,
Paul.

Hello,

In the hourly results, SAM reports a variable called "Hourly Dispatch Factors" that shows the TOD factor that applies in each of the 8,760 hours of the year.

I have asked the developers to add the TOD period to the hourly results. That would allow you to export a table of the hourly TOD periods and hourly energy values in kWh to Excel, and calculate the total kWh in each TOD period in the workbook.

That should be available in the next version of SAM, which we plan to release in September (2013).

Best regards,
Paul.
