Solar panels are rarely mobile and their angle is therefore fixed to the installation. Solar power is much stronger in summer than in winter, not to mention the length of days. Solar energy is at least three times more important in summer than in winter (see tutorial [[energy in the home]]), so the panels are sized and oriented for the most critical period: winter.

Définition du message (Chauffe eau solaire)
*en étant perpendiculaire aux rayons la densité énergétique est plus élevée, plus l’angle augmente plus le « nombre » de rayons captés sera réduit par unité de surface. Autrement dit la surface apparente du panneau, vue du soleil, réduit avec l’angle.
*la vitre reflète les rayons, si les rayons arrivent perpendiculairement au verre, tous entrent dans le panneau, plus l’angle augmente, plus la part de rayons reflétés est élevée.
