  • (3) Make sure that there is a data source near the location.

  • (4) Verify that the location/data source are correct. (5) Click on "Go to system info."

  • (6) Input 1kW system size. This will make PVWatts output the correct values for system design. (7) Leave as "Standard." (8) Leave as "Fixed (open rack)." (9) Set to "0" as system losses will be accounted for elsewhere. (10) Set to the desired tilt. (11) Set to the desired azimuth. (12) Click on "Go to PVWatts results."

  • (13) The average monthly insolation values - in red - can be used for the load and solar resource comparison. The lowest monthly value is always of particular interest.
