PANEL ORIENTATION AND TILT ANGLE
IRRADIANCE COEFFICENT ACCORDING TO SEASON AND AREA
The irradiance coefficient*, which varies according to the season and the
geographical area, allows to calculate the panels production.
Note : On an annual use or several seasons, the lowest irradiance
coefficient must be taken into account, in order to prevent your
installation well sized in summer from being not sufficient in winter.
Eg : in july, a 100W panel will be able to produce 4 to 5 times its power,
meaning 400W to 500W a day.
However, in december in the North of France, this same panel will only
produce 0,7 times its power, meaning only 70W.

PANEL ORIENTATION AND TILT ANGLE (ACCORDING TO THE HORIZON)
In order to optimize your panel's production, orient it towards as much as possible towards the
South**. Its tilt angle must be perpendicular to the sun's highest point, that varies according
to the season and the geographical area.

Note : For an annual use, if you cannot modify the tilt angle along the year, choose a fixed 30°-35° angle.
