The SAM web site will be upgrading Monday, May 23 from 4:00-5:00pm (Denver/mountain time). 

After doing a major change to our infrastructure, we have found a minor issue that we have corrected but will need to reboot the web site for it to take affect.

To make it as convenient as possible, we have scheduled it for Monday, May 23rd at 4:00pm (mountain). The process takes 15-20 minutes, but the site will only be unavailable for a short time. However, your session information will be lost (eg if you're writing a post, what you have written could be lost). 

When you create a new case or file, SAM populates inputs with default values to help you get started with your analysis. So, if you create a case for a power tower system with the single owner financial model, SAM populates the inputs on the Financing and System Costs pages with values that are reasonable for a typical project of that kind in the United States. The default values are just a starting point: As you develop and refine your analysis, you should change the inputs to values that are appropriate for your analysis scenario.

The documents listed below were used to develop the default cost data for SAM's Concentrating Solar Power models.
