Abstract

A photovoltaic device comprising: a base ( 1 ), a photovoltaic assembly ( 8 ) and a baffle plate ( 5 ), wherein the photovoltaic assembly is arranged in an inclined manner on the base from bottom up in a direction from front to rear, and behind the photovoltaic assembly, the baffle plate is arranged in an inclined manner on the base from bottom up in a direction from rear to front. The baffle plate reduces the profile coefficient and decreases the uplift by the action of wind load.

First claim

The invention claimed is:

1. A photovoltaic device comprising: a base, a photovoltaic assembly and a baffle plate, wherein the photovoltaic assembly is arranged in an inclined manner on the base from bottom up in a direction from front to rear, and completely behind the photovoltaic assembly, the baffle plate is arranged in an inclined manner on the base from top downwards in the direction from front to rear; and further comprising a spoiler which is arranged in an inclined manner completely behind the baffle plate from top downwards in the direction from front to rear, wherein a lower end of the spoiler is fixed onto the base, wherein a surface of the spoiler facing the baffle plate and a windward side of the spoiler are formed integrally and are cambered surfaces, and a surface of the spoiler at the opposed side to the baffle plate is a plane, wherein the baffle plate is positioned between the photovoltaic assembly and the spoiler, and wherein the baffle plate extends the entire length from an upper end of the photovoltaic assembly to the base.

2. The photovoltaic device according to claim 1 , wherein an upper end of the baffle plate is interfaced with the upper end of the photovoltaic assembly.

3. The photovoltaic device according to claim 2 , wherein a photovoltaic assembly front support pillar and a photovoltaic assembly rear support pillar are provided on the base, for respectively supporting a lower end and the upper end of the photovoltaic assembly.

4. The photovoltaic device according to claim 1 , wherein a photovoltaic assembly front support pillar and a photovoltaic assembly rear support pillar are provided on the base, for respectively supporting a lower end and the upper end of the photovoltaic assembly.

5. The photovoltaic device according to claim 4 , wherein an upper end of the baffle plate is fixed onto the photovoltaic assembly rear support pillar.

6. The photovoltaic device according to claim 5 , wherein a spoiler front support pillar is provided on the base, which supports the lower end of the spoiler; and a spoiler rear support pillar is provided on the baffle plate, which supports an upper end of the spoiler.

7. The photovoltaic device according to claim 6 , wherein the base comprises at least two base plates provided spaced from each other and in parallel, on which are provided with rails; and the photovoltaic assembly front support pillar, the photovoltaic assembly rear support pillar, and the spoiler front support pillar are mounted on the rails respectively.

8. The photovoltaic device according to claim 4 , wherein a first open slot is provided on the photovoltaic assembly front support pillar and a second open slot is provided on the photovoltaic assembly rear support pillar, with one end of the photovoltaic assembly being inserted into the first open slot of the photovoltaic assembly front support pillar and the other end of the photovoltaic assembly being inserted into the second open slot of the photovoltaic assembly rear support pillar.

9. The photovoltaic device according to claim 1 , wherein the spoiler is supported on the baffle plate.
