Dans le premier article de cette s\u00e9rie de blogs<\/a>, nous avons parl\u00e9 des avantages du surdimensionnement PV. Cependant, le succ\u00e8s d\u00e9pend de facteurs cl\u00e9s tels que la qualit\u00e9 des onduleurs, la configuration des strings et une surveillance assidue. Dans cet article, nous explorons ces facteurs essentiels qui permettent aux installateurs d’optimiser efficacement les syst\u00e8mes PV. <\/strong><\/p>\n

Qualit\u00e9 de l’onduleur<\/h2>\n

Le choix d’un onduleur de haute qualit\u00e9 est une exigence absolue pour chaque installation, mais encore plus pour faciliter le surdimensionnement du syst\u00e8me PV. Les composants internes de l’onduleur doivent \u00eatre capables de g\u00e9rer des charges accrues et des fluctuations de tension afin de garantir la fiabilit\u00e9 et la long\u00e9vit\u00e9 de l\u2019installation. En outre, la vitesse du syst\u00e8me de contr\u00f4le de l’onduleur est cruciale. Dans les situations o\u00f9 l’irradiation change rapidement, comme en cas de couverture nuageuse partielle, le courant peut fluctuer rapidement. L’onduleur doit rapidement ajuster la tension pour s’adapter \u00e0 ces changements.<\/p>\n

Les fabricants imposent souvent des limites et des directives sp\u00e9cifiques concernant le surdimensionnement des syst\u00e8mes PV afin de prot\u00e9ger l’int\u00e9grit\u00e9 et les performances du syst\u00e8me. Il est essentiel de respecter ces sp\u00e9cifications pour \u00e9viter d’endommager ou de d\u00e9grader les composants du syst\u00e8me. Certains fabricants limitent le surdimensionnement des panneaux PV \u00e0 un maximum de 110 %. Le Sunny Boy Smart Energy de SMA offre un onduleur de haute qualit\u00e9 bas\u00e9 sur les normes de qualit\u00e9 allemandes qui permet un surdimensionnement allant jusqu’\u00e0 200 %. La garantie de 10 ans offre aux installateurs et aux propri\u00e9taires une grande tranquillit\u00e9 d’esprit*.<\/p>\n

Investir dans un onduleur fiable est essentiel pour obtenir des performances optimales et minimiser le risque de d\u00e9faillance ou de r\u00e9duction de la dur\u00e9e de vie. Ces facteurs jouent \u00e9galement un r\u00f4le important dans la d\u00e9termination du retour sur investissement !<\/p>\n

Configuration des strings<\/h2>\n

Il est n\u00e9cessaire d’\u00e9tudier soigneusement la configuration des strings pour \u00e9viter de d\u00e9passer les limites maximales de tension et de courant dans les installations PV surdimensionn\u00e9es. Une configuration appropri\u00e9e des strings permet d’att\u00e9nuer le risque de surcharge et d’assurer un fonctionnement s\u00fbr et efficace du syst\u00e8me. Le fait de configurer correctement les strings permet \u00e9galement d’optimiser la production et la distribution d’\u00e9nergie, ce qui am\u00e9liore les performances et la fiabilit\u00e9 de l’ensemble du syst\u00e8me. Le SMA Sunny Design<\/a> est un outil pr\u00e9cieux pour mettre en place une installation s\u00fbre et rentable. Une fois que le syst\u00e8me fonctionne, SMA Smart Connected<\/a>, le service gratuit et automatique de surveillance int\u00e9gr\u00e9 \u00e0 chaque onduleur SMA, informe proactivement le propri\u00e9taire et le technicien sp\u00e9cialis\u00e9 des \u00e9v\u00e9nements (d\u2019erreur) qui se produisent.<\/p>\n

Surveillance et entretien<\/h2>\n

Comme pour toutes les installations solaires, la surveillance et l’entretien repr\u00e9sentent \u00e9galement des aspects essentiels de la gestion d’installations PV surdimensionn\u00e9es. Le portail de surveillance et de pilotage de SMA, Sunny Portal powered by ennexOS, permet aux propri\u00e9taires d’installations d’analyser les valeurs mesur\u00e9es, de visualiser et de comparer les rendements. Les installateurs peuvent suivre facilement les donn\u00e9es gr\u00e2ce \u00e0 l’application SMA 360\u00b0<\/a>. Ainsi, m\u00eame les \u00e9carts mineurs peuvent \u00eatre d\u00e9tect\u00e9s et r\u00e9solus rapidement. Le SMA Online Service Center<\/a> leur permet de rechercher des informations et de soumettre des demandes de service 24 heures sur 24 et 7 jours sur 7.<\/p>\n

\"Sunny<\/p>\n

Sunny Design<\/a> est un outil de calcul gratuit pour les syst\u00e8mes PV et les syst\u00e8mes \u00e9nerg\u00e9tiques complets. Les installateurs peuvent concevoir des installations PV sur mesure pour leurs clients. Sunny Design prend en compte toutes les r\u00e9glementations techniques applicables aux diff\u00e9rents composants et leurs livre les donn\u00e9es pertinentes pour une \u00e9valuation \u00e9conomique de l’installation. Cela signifie qu’ils peuvent concevoir des installations PV parfaitement adapt\u00e9es aux conditions locales sp\u00e9cifiques.<\/p>\n

Sunny Design permet \u00e9galement d’analyser l’ombrage. L’outil de planification int\u00e9gr\u00e9 Renusol le rend encore plus efficace.<\/p>\n
