What is typical year?
Typical year is a year of hourly meteorological data for a specific location derived from years of historical time-series solar resource data. These data files are commonly used for solar resource availability assessments at potential project sites or running energy simulations to obtain P50 solar production estimates.
SolarAnywhere typical year data can be downloaded or requested as either a typical GHI year (TGY) or typical DNI year (TDY) file. These files contain a years’ worth of hourly observations (8760 hourly observations) selected with 100% weighting on either GHI or DNI. The files are generated for a specified location using the following two-step process:
-
- The long-term average monthly total irradiance is calculated for each month. The years considered in calculating the long-term averages is dependent upon the geographic data region:
- The actual months in the historic record with the monthly total irradiance values closest to the long-term averages calculated in step 1 are included in the TGY or TDY files.
- The long-term average monthly total irradiance is calculated for each month. The years considered in calculating the long-term averages is dependent upon the geographic data region:
The final TGY or TDY file will include 12 months of actual data from various years in the historical time series. For example, if January of 2010 has the monthly total irradiance closest to the long-term average monthly total irradiance for all Januarys as calculated in step 1, it will be included in the file. This is illustrated below.
