I am looking to find the expected P50 net annual energy production for each year of a 25 year plan. SAM P50/P90 simulation only provides the net annual production for one year. I would like to know if anyone knows how I can obtain this data.

How can I create a simple weather file which includes only monthly insolation data excluding any hourly or sub-hourly records?

I have data in the format:

Stochastic Analysis - Input Values


When setting up variables for a stochastic analysis I noticed that an input variable for a State-sponsored Production Based Incentive (PBI) expressed as $/kWh is not available.

I want to demonstrate a high correlation between total installed costs and varied cash incentive levels and their impact on the resulting Net Present Value and simple Payback.

I've already used these same variables in a parametric analysis and wanted to compare results with a stochastic analysis.

Please advise.

Can I translate my analyses internationally?

Is there a way I can create SAM analyses in different parts of the world? I'm specifically interested in doing so within West Africa- but I'm not sure how to find a) applicable data, or b) what (if any) US area might be the most comparable.

any suggestions?

Solar energy , Levelised cost of electricity generation

I am renewable consultant for residential project in India, I am exploring it for use in new residential project in India where we plan to use solar energy.
Thanks for wonderful software, I am planning to calculate levelised cost of energy with photovoltic cells.
Is there any way where I get levelised cost of electricity generation ?
I am a newbie so sorry if I am missing something basic.

Thanks a lot for help.

stepwise_wipp.exe stops working

Greetings ALL,

When I run the Statistical simulation example I consistently get a windows error message saying that stepwise_wipp.exe has stopped working. I'm forced to close SAM through the Windows Task Manager.

Anyone know what's going on with that?

Many thanks,
