Precautions
Magnetic Fields
Avoid nearby magnetic fields. The SunEye is a sensitive measurement device. Magnetic fields
from nearby iron can affect measurements and stronger magnetic fields may damage the Sun-
Eye. Always store and transport SunEye in the included magnetically shielded case to preserve
the compass calibration. Never store magnetized objects, such as hand tools or other magnetized
objects, in the case.
Temperature
Do not operate or subject the SunEye to temperatures beyond the published operating and stor-
age temperature specifications found in “Maintenance and Troubleshooting” of the User Guide
and in the Quick Start Guide.
Moisture
Exposure to rain or condensation may damage the SunEye. Do not expose to rain. Condensation
will occur on the case whenever the dew point exceeds the case temperature. This can occur if
moving the SunEye from a cold outside environment into a warm office environment. Store the
SunEye in its protective case whenever not in use to protect and insulate the instrument.
Dirt and Dust
A precision optical fisheye lens is a key element of the SunEye. Protect from dust and dirt. Keep
lens cap on when stored between uses. Clean lens regularly with soft lens cleaning cloth.

Understanding the SunEye
Battery
CAUTION The SunEye contains a lithium battery and should not be disposed of with general refuse. Dispose
of the SunEye in accordance with all local codes and regulations for products containing lithium
batteries. Contact your local environmental control or disposal agency for further details.
WARNING Only use the power supply supplied by Solmetric or a UL or certified equivalent with a
rated output of 5 Vdc 2.6 A.
Understanding the SunEye
The SunEye (patent pending) provides complete solar access and shade analysis in an integrated
powerful hand-held tool for the following uses:
• Solar panel system design and installation
• Passive solar house design and green architecture
• Landscape design and landscape architecture
• Home and property inspection
Solar Panel Design and Installation
The SunEye is an invaluable tool for the professional solar installer, saving time and money and
helping to design the highest performance systems. Home and business owners who care about
the performance and payback of their systems hire installers that use the SunEye. It is equally
useful for photovoltaic (PV), passive hot water, roof mount or ground-mount systems. The Sun-
Eye can help:
• Optimize new systems for maximum production.
• Analyze existing installations to solve problems of under production
• Identify specific shade-causing obstructions and know instantly how much additional energy
would be produced if the obstructions were removed.
Passive Solar House Design and Green Architecture
The SunEye is the right tool for the job when you need accurate site-specific solar access data
for a new home or renovation. Optimize the orientation of a structure by identifying where and
when the sun will shine. The SunEye helps you answer many different questions. For example,
“Will there be enough sun in the winter for passive heating of the house given the site-specific
shading?”, or “How will removing the large oak tree on the south-west corner affect the warm-
ing and cooling of the building?” Furthermore, by collecting data inside an existing structure,
you can identify the amount of direct sunlight that will enter a window or skylight or identify the
perfect location for a new window or skylight.

Installing the SunEye and Desktop Companion Software
Home and Property Inspection
The SunEye gives professional home and property inspectors a way to provide their clients with
important information about the solar access of a property. This information can be useful for:
• Identifying potential sites for solar panels, gardens, or new windows.
• Determining the amount of passive solar heating or cooling a particular building will experience.
• Determining how much direct sunlight will enter a particular window or skylight.
Installing the SunEye and Desktop Companion Software
NOTE The software on the hand-held unit and the Desktop Companion are simultaneously installed
from the same installation file. Refer to “Upgrading or Downgrading Software” on page 5-5 for
more information.
1Before you start using your SunEye it is recommended that you install the SunEye Desktop
Companion software. Although you will not have any data to analyze on the desktop yet, this will
allow you to view the user’s guide.
2The SunEye will most likely not need to be updated the first time you install the Desktop
Companion on your PC. However, it will prompt you to connect the SunEye while it determines
if you already have the latest version installed. You will then be given the option to reinstall or
skip the SunEye install and proceed straight to the Desktop Companion installation.

Charging the Battery
Charging the Battery
• The battery in the SunEye is not removable. It may be recharged by attaching the device to the
AC wall-plug or optional car charger via the DC power port on the right side of the device. Al-
ternately, the SunEye will trickle charge using the USB data port connected to a PC. However,
the trickle charge can take up to 33 hours to fully charge the SunEye. If operating the SunEye
while only plugged into a USB port, the SunEye will draw more current than the USB port can
supply. Therefore, the battery may discharge if connected to USB with power on.
• If the battery is completely discharged, you must use the AC charger if you want to operate the
device while it is charging. The USB cable and the car charger do not supply enough current to
both charge a completely discharged battery and operate the device.
• Charging the battery can take up to 2.5 hours. Once the battery has been charged, the device will
operate without the external power connection for approximately 6 hours of continuous opera-
tion.
• Power Status LED Indicator:
• Green = SunEye is turned on under battery power.
• Red flashing = SunEye is plugged into power and battery is charging.
• Red solid = SunEye is plugged into power and battery is fully charged.
• To see the current battery level of the SunEye, select the Menu icon, the Tools icon, and then se-
lect About SunEye.
• It is not harmful to the device to be continuously connected to AC power or to a computer. It is
also not harmful to the device or to your data for the battery to fully discharge.
Getting Familiar with the SunEye
The SunEye includes the following features to make it easy and efficient to use.
• Point-and-click data gathering
• Instant measurement results
• Plots sunpaths for the latitude and longitude of the site
• Determines annual, seasonal, monthly, and quarter-hourly shading percentages
• Automatically adjusts data for magnetic declination for a specific location
• Stores more than 100 site readings on the hand-held unit

About Sessions and Skylines
About Sessions and Skylines
The SunEye organizes the solar access data in Sessions and Skylines.
Session A “Session” is a collection of measurement data that was taken for a
particular site visit. You will generally create a new session for each
client or site you visit. An example of a session name might be
“Roger Smith’s House”. One session will generally contain multiple
skyline data sets and photos.
You can add notes to the session to help identify the session in the
future. For example, you could include client contact information or
other information about the particular site being analyzed.
Skyline A “Skyline” is a single set of solar access data captured at a specific
location within a site. For example, one skyline might be captured at
the north side of the roof of Roger Smith’s house. Another skyline
might be captured at the center of the roof of Roger Smith’s House. A
skyline includes a fisheye image, a sunpath diagram, and solar access
calculations. Every time a new skyline is captured, the data is stored
under the current session. One session can hold many skylines.
You can add notes to a skyline to help identify the skyline in the
future. For example, you could include the location of the captured
data such as “north side of roof.”
NOTE The SunEye can store more than 100 skylines (the actual number depends on the particular
images captured and can store up to 200 in some cases). The number of sessions can vary. You
can have one session with 100 skylines or 100 sessions with one skyline each.
Create a Session
A session is like a site visit. You would generally create a new session for each new client. Each
session will generally consist of multiple skyline data sets. The Session menu selections are as
follows:
•Weather Properties – shows the properties for the selected weather model. See “Weather, Air
quality and Clouds” on page 4-3.
• Session Data Summaries– allows you to select the skylines used to compute the monthly solar
access averages or session obstruction elevation average or maximum. See “Session Data Sum-
