actual weather data , measured on location

Working with SAM , I how can I enter actual measured weather data in the system to optimize on the favorable weather data measured on actual site location ? I am aware of that I can up load various weather stations from SAM, but they may not be fully representative, f.ex. Iridiance in Jamaica at certian locations ( Latitude 18 Deg ) seems to be 5- 10 % higher compared to weather data obtained from Sam for Puerto Rico weather station in same laitude range ? Thanks.

For solar systems, you can use the TMY3 Creator available from the Location and Resource page. As you will see in the TMY3 Creator window, SAM requires several columns of weather data.

Please see the TMY3 Creator Help topic for instructions.
