What is the recommended spacing between SunEye shots?
There is no standard spacing that we are aware of. However, there are some general guidelines. For smaller residential systems, measurements at the four corners of the array may be enough. For larger systems, it may be desirable to take measurements every 20 ft (6m) or so in both directions. Data can be taken in […]
How many Skylines can I have stored in the SunEye?
The SunEye can normally store over 100 Skylines. The actual number depends on the nature of the images. When the data is transferred to the desktop software, the SunEye is cleared so a new set of 100 Skylines can be started. With modern computers, the large computer disk space typically makes the number of Sessions […]
How long does the SunEye need between Skyline shots?
The SunEye camera needs a few seconds to auto-adjust for lighting after you enter preview mode. When you press snap, hold the SunEye steady until you hear the beep that indicates the shot is complete. After the Skyline is snapped, the SunEye processes the data, and this takes a few seconds before it is ready […]
Do you need to hold the SunEye at the same height as the solar panels?
For the most accurate results, the SunEye camera should be held at the height and location of the solar panels. Normally the lowest part of the panel or array should be measured so that the worst case shading is measured. The exact height is normally not so critical, and several inches or one foot of […]
Open Sky sometimes is detected as obstruction (or vice versa). Is there a way to remedy this?
The SunEye incorporates an “Open Sky Detection” algorithm which is digital image processing to determine what is open sky and what is obstruction. This algorithm works well in most situations. However, in some cases it may be “fooled”. Check that your camera is clear and reasonably clean, and that images are appearing in the result. […]

The installation program updates both the SunEye device and the SunEye desktop software*.The software also checks for updates when connected to the internet, so that you can ensure that you have the latest version. *Note: If you have mismatched software versions it is […]
It is sometimes difficult to see the SunEye display in bright sunlight. Is there any way to overcome this?
In some lighting situations, the SunEye screen can be difficult to read. The screen is ?transflective? which means it will actually use reflected light. So brightness may increase when you reflect the sun toward your eye more directly. This may seem counter-intuitive. Also, shading the screen sometimes helps in some situations, although it can be […]
How can I meet the requirements for the City of Pasadena?
The City of Pasadena, California has a requirement to measure obstruction elevation every 30 degrees, from east to west (90 to 270 degrees), so that is seven points. The Obstruction Elevation view available in SunEye version 2.8 or higher can display these values conveniently. The Obstruction Elevation view can be configured with the 30 degree […]
