Why are values for financial estimates (cost/watt($), Opex Cost, LCOE($/kwh), NPV($), IRR) showing "0" after running a PV layout.  


  1. Financial estimation needs to be turned on for PV Layout runs.  You can turn it on by going to Customization in PV Layout.
  2. Missing weather file.  A weather file needs to be available for the site to run production estimates, which leads to generate financial estimates.  You can check if there weather file source near your project by expanding the Site Overview and check if there are weather files available under Choose Weather Source file.
