1. Technical Field
The invention generally relates to solar generation, particularly to solar energy collectors.
2. Related Art
Price climbing of petroleum forces replacement energy to be developed fast. Green energy under natural environment, such solar energy and wind power, can effectively reduce greenhouse gas emission. Therefore, green energy must be seriously treated.
A conventional mechanism of collecting solar power is illustrated in
An object of the invention is to improve efficiency of collecting solar power in a limited space.
To accomplish the above object, the invention includes a solar energy collector and a sunbeam guiding unit. The solar energy collector is formed by a bottom plate and four side walls, all of which are made by solar panels. The sunbeam guiding unit is disposed in or over the solar energy collector for reflecting or refracting the sunbeams to the bottom plate and the side walls.
Referring to
The solar energy collector 2 is a hollow cuboid formed by a bottom plate 20 and a plurality of side walls 21, all of which are made by solar panels. The solar energy collector 2 absorbs solar energy by sunbeams 51 and outputs power to an external unit 6 (shown in
The sunbeam guiding unit 3 is disposed in a hollow portion 22 of the solar energy collector 2 on the bottom plate 20 for reflecting the incident sunbeams 51 to the side walls 21. Thus, the sunbeam guiding unit 3 may be a reflecting mirror set.
Referring to
In comparison with prior art, the invention increases the efficiency of absorbing solar energy within a limited space by means of the three-dimensional solar energy collector 2. Also, the invention enhances the efficiency of receiving sunbeams by the sunbeam guiding unit 3.
It will be appreciated by persons skilled in the art that the above embodiments have been described by way of example only and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims.
