Pourquoi la production r\u00e9elle est inf\u00e9rieure \u00e0 la pr\u00e9visionnelle ? Pour 2024 et 2025, il y a eu une nette baisse d’ensoleillement sur Ol\u00e9ron. Il y a eu quelques petites pannes sur 2 centrales. Pendant les canicules, les panneaux produisent moins aussi. <\/p>\n\n\n\n

Pourquoi la canicule diminue la performance des panneaux solaires ?<\/h6>\n\n\n\n

Contrairement aux id\u00e9es re\u00e7ues, ce n\u2019est pas la chaleur \u00e9mise par le soleil qui permet aux panneaux photovolta\u00efques de produire de l\u2019\u00e9lectricit\u00e9, mais le niveau de luminosit\u00e9<\/strong> : s\u2019il fait tr\u00e8s chaud, cela ne signifie pas qu’une installation solaire sera plus performante et productrice en \u00e9nergie.<\/p>\n\n\n\n

C\u2019est m\u00eame tout l\u2019inverse : \u00e0 partir d\u2019une certaine temp\u00e9rature, la chaleur peut nuire \u00e0 l\u2019efficacit\u00e9 des panneaux solaires.<\/strong> Il est en effet estim\u00e9 que les modules photovolta\u00efques fonctionnent de fa\u00e7on optimale jusqu\u2019\u00e0 environ 25\u00b0C. Au-del\u00e0, ils accusent une perte de rendement allant jusqu\u2019\u00e0 0,5 % de performance par degr\u00e9 suppl\u00e9mentaire*.<\/p>\n\n\n\n

Ainsi, en 2019,  lors de la vague de chaleur, le 24 juillet, \u00e0 l\u2019\u00e9chelle nationale, le parc photovolta\u00efque de la France, d\u2019une puissance th\u00e9orique maximale de 8.612 MWh n\u2019aura produit que 6.100 MWh. Pour rappel, selon une d\u00e9finition de M\u00e9t\u00e9o France, une vague de chaleur se produit lorsque \u00ab la temp\u00e9rature moyenne nationale soit au-dessus de 25,3\u00b0C pendant 1 journ\u00e9e ou alors au-dessus de 23,4\u00b0C pendant 3 jours cons\u00e9cutifs \u00bb<\/em>. <\/em><\/p>\n\n\n\n
