Fixture positioning tips
Operation
Choose a suitable location where sunlight can directly reach the solar panel.
Avoid obscuration by eaves or trees.
In the northern hemisphere, favor installation to the south of obstacles (on facades, on a pole or
other), or to the east or west. Do not install due north of an obstacle.
In the southern hemisphere, favor installation to the north of obstacles, to the east or to the west.
Do not install due south of an obstacle.
Recommendations
The most critical time for solar lighting is winter.
Days are shorter than in summer, and the sun is lower in the sky, therefore the cast shadows are
longer. Therefore, it is advisable to assess the correct positioning of a solar lighting device in
winter, to avoid shadow areas.
It is advisable to draw up a layout plan of the site before installation. You can indicate the location
of the devices there, making sure to note their identification numbers indicated on their labels.
Example
In winter, the sun is 21°in Bordeaux, France at noon. A 2-meter-high wall then has a shadow cast
of 5 meters directed towards the North.
In summer, the sun is 68°in Bordeaux, France at noon. A 2-meter-high wall then has a shadow of
70 cm directed towards the North.
In Bordeaux in winter, the sun rises in the southeast at 7:30 a.m. and sets in the southwest at
4:30 p.m.
In Bordeaux in summer, the sun rises in the northeast at 4:30 a.m. and sets in the northwest at 8
p.m.
