Investment expenditure be an important research direction.
Followed by for " intermittent, spatial distribution changes at any time " of solar energy the characteristics of, photovoltaic hair is improved by design
Electric installation improves its efficiency for receiving sunlight, to improve the utilization rate of solar energy；No matter which kind of solar energy equipment, when it
When sun reception device can be vertical with sunray holding always, so that it may greatly improve the solar energy utilization ratio of unit area.
In recent years, the research of many this respects has been carried out both at home and abroad.Such as professor SUMHui of Hong Kong University has studied sun angle
With the relationship between energy receptance, as a result, it has been found that: implement solar tracking technology, after making sunlight vertical incidence always, solar energy
Utilization rate improves 37.7%.It is known that sunlight is radiated at the angle in fixed angle solar power generation devices in one day
Degree can change over time, therefore electric energy caused by the solar energy of unit energy (i.e. generating efficiency) is also with daily middle different periods
Time change.In sunray vertical irradiation at solar power generation devices surface (such as noon), the sun of unit energy
Electric energy caused by energy is most strong (i.e. generating efficiency highest).And the inclination angle that sunray is irradiated to solar power generation devices surface is cured
Greatly, electric energy caused by the solar energy of unit energy is weaker (i.e. generating efficiency is lower, such as morning and dusk), therefore to the sun
The research and development of energy tracking device are to improve the important method of solar energy receiving efficiency.Current existing solar tracking technology
In, most study is automatically tracked to two axis, it can track azimuth and the elevation angle of the sun simultaneously, shine sunlight vertically always
It penetrates on solar collector, substantially increases solar energy utilization ratio.However, though two axis tracking effects are good, its system structure
Complexity, mechanical wear are big, it is high to cause installation cost, therefore need largely to put into terms of equipment investment, are unfavorable for improving too
Positive energy power benefit.
