In the middle of winter, in France, the sun has a zenith at 30° with the horizon, this is its maximum height. In summer, at the same latitudes, it rises to 60°. Ideally, the panels will be installed at a 60° angle to the horizon, south-facing. Otherwise, to limit the losses, one can put them vertically against a wall, it is more interesting and less dangerous than on roofs.

In the middle of winter, in France, the sun has a zenith at 30° with the horizon, this is its maximum height. In summer, at the same latitudes, it rises to 60°. Ideally, the panels will be installed perpendicularly to the winter sun rays, so 90°+30°=120°. They form a 120° angle with the horizon, south oriented (see scheme) . Otherwise, to limit the losses, one can put them vertically against a wall, it is more interesting and less dangerous than on roofs.

Définition du message (Chauffe eau solaire)
En plein hiver, en France, le soleil a un zénith à 30° avec l’horizon, c’est sa hauteur maximum. En été, sous ces mêmes latitudes, il monte à 60°. Dans l’idéal, les panneaux seront installés perpendiculairement aux rayons solaires d'hiver soit à 90°+30°=120°. Ils forment donc un angle de 120° à l’horizon, plein Sud (voir schéma). Sinon, pour limiter les pertes, on peut les mettre à la verticale contre un mur, c’est plus intéressant et moins dangereux que sur les toits.
