Financial Model Documentation

Hi Paul

Are there updated Spreadsheets as tools to help you understand how SAM 2017.9.5 financial models calculate the different metrics on the Results? Current spreadsheets examples on SAM resources page seem to be out of alignment with the SAM 2017.9.5.

i.e -LCOE and NPV Calculations Using Excel Formulas
-Payback Period Calculation for Residential and Commercial
-Residential and Commercial Financial Models

SDK API to save/load data container

SDK Tool provides a way to Save the variables in the data container to a data file. (.bdat) and Load data file (.bdat).

I'm looking for ways to save and load data container via Java API. Don't see anything listed in SSC guide (SSCJNI) API list.

Is there an API that can be invoked programatically to save and load the data container like SDK tool?

Thanks
Ashok

How does the approach temperature of cooling water affect the power cycle efficiency of CSP plant?

Hello. I've been try to understand how the approach temperature of cooling water affects the power cycle conversion efficiency of a hypothetical wet-cooled parabolic-trough CSP plant located in Mojave, Californa. The attached figure shows the yearly average efficiency as a function of the approach temperature. My question is why T_approach = 10C has the highest efficiency instead of T_approach = 5C. Thank you.

the parabolic trough simulation result

Dear Paul Gilman,

I try to simulate a plant with the parabolic trough physical.
When I set the "collector azimuth angle" as 90°,and I find the thermal energy to the power block will be more than the thermal energy produced by the field in the data tables of result. I am confused about the result, so I guess something will be ignored by me. The attachment is my sam file.

I would appreciate it a lot if you would give me a reply.

Thanks and Best regards.

Isolated or independent PV-systems

Hello!
I'm doing a project about PV-residential/commercial taking Piura,Peru region as a reference and I'm analyzing how the project will change if enable battery; but I don't know how to set up that the battery only load from the system.
Also, I know the program simulate different projects that are conexion to the grid and when there are excess generation,these energy is injected to the grid. However, in Peru can not perform the same.

SAM API not producing 'generation' data

I'm using the python api, trying to get the api example to work. I'm able to get the data table, but when I go to produce the generation column, it comes back all zeros.

DC to AC Ratio Not Properly Displayed

I designed a DC to AC Ratio of 1.24 and then go to the time value graph series to show the clipping and degradation of DC over a 25 year period, along with the AC kW generation overplayed, and staying constant over that time. But this is not properly reflected on the summary screen for annual energy production of kWhs. The kWh are degraded over time. Please advise.

Using SAM to get the blended $/kWh from interval data

Hello all,

I'm working with a couple of companies that do not like sharing their electric bills when they put out a request for proposals (RFP), as many times they get special rates after negotiating with the utilities. This represents an issue when they try to get accurate quotes for on site renewable energy.
