California Solar Resource Calculator for Tilted Surfaces

Welcome to the UCSD Solar Resource Calculator!

To compute the solar radiation on a tilted plane, click somewhere on the map and enter the tilt information in the pop-up. Your results will be displayed below.
The currently supported area is a small area surrounding San Diego up to southern Los Angeles. More to come!

Methodology and References

Using the hourly solar energy values provided by the NSRDB 10km-grid, 8 years (1998-2005) of hourly tilted plane estimates are computed and converted to monthly and annual averages over this period. As noted below, several calculation steps are pre-processed in an effort to minimize the on-demand computations performed by the server.
