• Calculates the monthly, seasonal, and annual solar access percentages.
• Calculates the annual solar resource percentages.
N O T E The accuracy of the measurement is directly related to how close to true south (or north in the
southern hemisphere) the compass needle points and to how level the unit is held at the time the
skyline is captured. Care should be used during this critical step. If the orientation is not within
+/-30° of true south (or north in the southern hemisphere) during the picture snap and /-
5° of level, a warning message will be displayed indicating the issue. It is strongly recommended
that you delete this skyline and start again if this occurs. To do this, press
Retry .
N O T E The SunEye will automatically correct the skyline for offsets in the azimuth up to +/-30° and tilt
up to +/-5° . For best results, hold true South (or North in the Southern Hemisphere) and level as
accurately as possible. The SunEye will alert the user when the azimuth or tilt cannot be corrected
and force another measurement. The SunEye will alert the user if the azimuth or tilt correction is
significant and can be corrected is the user wants to. Press Continue to proceed with that
measurement and the auto correction or press Retry to return to Preview mode to make another
measurement.

5 Verify that the software has correctly identified the open sky and obstructions. You can verify
that the yellow and green shading is correct by looking at the image through the shaded colors.
Make sure obstructions are green and open sky is yellow. Incorrect identification will affect the
accuracy of the calculations. Correct the shading if needed with the Edit tool as described below.
Skylines are automatically saved every time they are captured. To delete the skyline data that
you just captured, press the navigation button to the left. Alternatively, to immediately capture
another skyline, press the
Star button.
