Is there any way to avoid the usage of the EPW latitude and longitude when the following error occurs?

   ** Warning ** Weather file location will be used rather than entered (IDF) Location object.
   **   ~~~   ** ..Location object=SITELOCATION
   **   ~~~   ** ..Weather File Location=Barcelona - ESP SWEC WMO#=081810
   **   ~~~   ** ..due to location differences, Latitude difference=[0.10] degrees, Longitude difference=[0.10] degrees.
   **   ~~~   ** ..Time Zone difference=[0.0] hour(s), Elevation difference=[68.17] percent, [12.85] meters.

I thought about modifying the latitude and longitude in the EPW file before running but I am rather looking for an IDF solution. What are the consequences of using a different latitude and longitude besides slightly different solar calculations?

Thanks Johann
