The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic roofing elements having a structured profile. For example, one aspect of the invention is a structured photovoltaic roofing element including: a structured roofing substrate presenting on its top-facing surface a plurality of differently-shadowable zones; and a plurality of bypassable photovoltaic elements, each of the bypassable photovoltaic elements comprising a bypass diode connected in parallel with a photovoltaic element, each of the bypassable photovoltaic elements being disposed in a differently-shadowable zone; wherein one or more of the bypassable photovoltaic elements is disposed in a different differently-shadowable zone than one or more of the other bypassable photovoltaic elements.

L'invention concerne en général la génération d'énergie électrique photovoltaïque. L'invention concerne plus particulièrement des éléments de toiture photovoltaïques à profil structuré. Selon un aspect de l'invention, un élément de toiture photovoltaïque à profil structuré comprend : un substrat de toiture structuré présentant sur sa surface supérieure une pluralité de zones pouvant être ombragées différemment; et une pluralité d'éléments photovoltaïques pouvant être contournés, chacun des éléments photovoltaiques pouvant être contourné comprenant une diode en parallèle avec un élément photovoltaïque et étant disposé dans une zone pouvant être ombragée différemment. Un ou plusieurs éléments phovoltaiques pouvant être contournés sont disposés dans une zone pouvant être ombragée différemment différente de la zone des autres éléments photovoltaïques pouvant être contournés.
