Un panneau solaire est un dispositif qui convertit directement ou indirectement l'\u00e9nergie du rayonnement solaire en \u00e9nergie \u00e9lectrique par effet photo\u00e9lectrique ou photochimique, en absorbant la lumi\u00e8re solaire. Le mat\u00e9riau principal de la plupart des panneaux solaires est le silicium.<\/p>\n
Structure et composition
\n1) Verre tremp\u00e9
\nSa fonction est de prot\u00e9ger le corps principal de la production d'\u00e9nergie (comme la cellule), et la s\u00e9lection de la transmission lumineuse est requise :
\n1. La transmission lumineuse doit \u00eatre \u00e9lev\u00e9e (g\u00e9n\u00e9ralement sup\u00e9rieure \u00e0 91%) ;
\n2. Traitement tremp\u00e9 ultra-blanc<\/p>\n
2) EVA
\nUtilis\u00e9 pour coller et fixer le verre tremp\u00e9 et le corps principal du module de production d'\u00e9nergie (comme une cellule). La qualit\u00e9 du mat\u00e9riau EVA transparent influence directement la dur\u00e9e de vie du module. Expos\u00e9 \u00e0 l'air, l'EVA vieillit et jaunit facilement, ce qui affecte la transmission lumineuse du module et, par cons\u00e9quent, la dur\u00e9e de vie des composants. Outre la qualit\u00e9 de l'EVA, la qualit\u00e9 de production d'\u00e9nergie du module est \u00e9galement fortement influenc\u00e9e par le processus de laminage du fabricant.<\/p>\n
3) Cellules
\nLeur fonction principale est de produire de l'\u00e9lectricit\u00e9. Sur le march\u00e9 de la production d'\u00e9lectricit\u00e9, les cellules solaires en silicium cristallin et les cellules solaires \u00e0 couches minces sont les plus r\u00e9pandues, chacune pr\u00e9sentant ses avantages et ses inconv\u00e9nients.
\nLes cellules solaires en silicium cristallin ont des co\u00fbts d'\u00e9quipement relativement faibles, mais la consommation et les co\u00fbts des cellules sont \u00e9lev\u00e9s, mais l'efficacit\u00e9 de conversion photo\u00e9lectrique est \u00e9galement \u00e9lev\u00e9e, ce qui est plus adapt\u00e9 \u00e0 la production d'\u00e9lectricit\u00e9 sous la lumi\u00e8re du soleil ext\u00e9rieure ; les cellules solaires \u00e0 couche mince ont des co\u00fbts d'\u00e9quipement relativement \u00e9lev\u00e9s, mais consomment et batterie Le co\u00fbt est tr\u00e8s faible, mais l'efficacit\u00e9 de conversion photo\u00e9lectrique est plus de la moiti\u00e9 de celle de la cellule en silicium cristallin, mais l'effet de faible luminosit\u00e9 est tr\u00e8s bon et elle peut g\u00e9n\u00e9rer de l'\u00e9lectricit\u00e9 sous une lumi\u00e8re ordinaire, comme la cellule solaire sur la calculatrice.<\/p>\n
4) Fond de panier
\nUtilis\u00e9 pour l'\u00e9tanch\u00e9it\u00e9, l'isolation et l'imperm\u00e9abilisation (g\u00e9n\u00e9ralement le TPT, le TPE et d'autres mat\u00e9riaux doivent \u00eatre r\u00e9sistants au vieillissement. La plupart des fabricants de composants ont une garantie de 25 ans. Le verre tremp\u00e9 et l'alliage d'aluminium sont g\u00e9n\u00e9ralement acceptables. La cl\u00e9 est de savoir si le fond de panier et le gel de silice peuvent atteindre Require.)<\/p>\n
5) Stratifi\u00e9 de protection en alliage d'aluminium
\nJouer un certain r\u00f4le d'\u00e9tanch\u00e9it\u00e9 et de soutien<\/p>\n
6) Bo\u00eete de jonction
\nIl prot\u00e8ge l'ensemble du syst\u00e8me de production d'\u00e9lectricit\u00e9 et fait office de station de transfert de courant. En cas de court-circuit d'un composant, le bo\u00eetier de jonction d\u00e9connecte automatiquement la cha\u00eene de batteries court-circuit\u00e9e afin d'\u00e9viter la combustion de l'ensemble du syst\u00e8me. Le choix des diodes est primordial dans le bo\u00eetier de jonction. Les diodes correspondantes varient \u00e9galement selon le type de cellule de l'assemblage.<\/p>\n
7) Gel de silice
\nUtilis\u00e9 pour sceller la jonction entre le composant et le cadre en alliage d'aluminium, et entre le composant et la bo\u00eete de jonction. Certaines entreprises utilisent du ruban adh\u00e9sif double face et de la mousse \u00e0 la place du gel de silice. L'utilisation domestique du gel de silice est simple, pratique et facile \u00e0 utiliser, et son co\u00fbt est tr\u00e8s faible.<\/p>","protected":false},"excerpt":{"rendered":"
