Field of the Invention
[1]
This invention generally relates to a solar panel module according to the pre-characterizing clause of claim 1.

Background of the Invention
[2]
Since petroleum resources on Earth are limited, energy demands have shifted toward alternative energies dramatically in recently years. Among the alternative energy sources, solar energy shows the most promising potential. In practical application, the power generating efficiency of a solar panel is still limited due to some problems to be solved. First, the power generating efficiency of a solar panel is generally inversely proportional to its operating temperature. Thus, the higher the operating temperature of a solar panel, the lower the power generating efficiency. Accordingly, even in areas with sufficiency sunlight, the power generating efficiency would be adversely affected due to the environmental temperature changes and the temperature increase caused by substantially long-term power generation. In addition, the power generating efficiency is proportional to the amount of sunlight. However, the incident angle of sunlight in areas of different latitudes is different, and the incident angle varies at different time in a day because the rotation axis of the Earth is tilted. Therefore, a solar panel module disposed in a stationary manner would suffer from low power generating efficiency because sunlight does not enter the solar panel perpendicularly at most of time.
