| 摘要 |
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. |
