• Allows for input of specs for collectors not listed
• Allows for input of specs for solar hot water collectors not listed
• Uses F-chart calculations
• Computes monthly sunpaths for specific latitude
• Contains World weather data (WMO/NREL)
• Enhanced exports capabilities (.pdf, .csv, jpg, etc.)
• Maintains Report Health Diagnostics
• Uses English or Metric Units
• Generates fully customizable reports (use your business name/logo, etc.)
• Stand-alone software, no internet connection required (after initial registration and download of local weather data)
• Automatically adjusts for magnetic declination, latitude, etc.
• Allows for changes
