** For the offer to take effect, there must be less than 2 hours of direct sunlight between 10am and 6pm on the given day, as calculated by the METNEXT Sun Index ®, which calculates the sunshine duration for all Sunêlia sites every day. Sunshine duration is defined as the period during which the sunlight is of sufficient intensity (= 120W/m2) to produce clear shadows (source: Météo-France). The index is calculated by METNEXT (a division of Météo France) on the basis of data recorded by the Météosat 2 satellite.
