Trouble with SWH Simulation

Hi Aldo,

The image you posted did not render correctly. To include and image with your post, please attach it as an image file and then you can insert it to your message.

Anyway, I think the error you are seeing is about the building electric load profile estimator (BELPE), which is enabled by choosing the Calculate Load Data option on the Electric Load data. You might try using the Input Time Series Load Data instead. This data is used for the electricity bill calculation, so may not be relevant to your solar water heating model.

I noticed that you are modeling a system in the southern hemisphere with a solar collector azimuth angle (on the Solar Water Heating page) of 180 degrees. That would be facing north, perhaps you should change that to zero degrees.

Best regards,
Paul.

Hi Aldo,

Those inputs can be found on the following input pages:

The annual AC degradation rate is an annual reduction in the system's output and is on the Lifetime and Degradation page.

There are different escalation rates in SAM. In general, an escalation rate is an annual percentage increase in cost that applies in addition to inflation. There are escalation rates on the Electricity Rates page, Incentives page, and System Costs page, for example.

The load growth rate is an annual increase in electricity usage on the Electric Load page.

Best regards,
Paul.
