Time Series Graph

Does the hourly data in the data tables and time series graphs account for annual degradation, or does it represent the performance in the first or second year?
SAM's performance models (except Geothermal) run a simulation for one year, and the hourly data that you see after running simulations on the Data and Time Series page are for that one year, which SAM assumes is for Year 1 of the project cash flow, or the first year that the system operates. 
In other words, the hourly data does not include the effect of the annual degradation rate that you specify on the Degradation input page.
