Background technology
The energy is the material base of human social activity, but with the increase of fossil fuel usage amount, people but must not
Shortage of resources is not faced and the problem of environment goes from bad to worse.Solar energy as a kind of cleaning natural regenerative resource, take no
To the greatest extent, it is nexhaustible.Development and utilization solar energy, had both been not in the pollution of air, and had not also interfered with the ecological balance of nature.
It is that solar energy tails device that foreign countries are general at present, and this device inconvenience is mobile or assembles and disassembles, and ginseng must just be adjusted again every time by having moved
Number, setting data and adjustment parameters, its principle, circuit, technical ability, equipment are all very complicated, and layman can not be random
Operation.And at present domestic many solar panel arrays be substantially it is fixed, it is impossible to make full use of solar energy resources, generate electricity
Inefficiency.Nearest Hebei photovoltaic power generation equipment Co., Ltd exclusively have developed based on GPS location system can be in movement
The intelligent solar for accurately tailing the sun whenever and wherever possible in equipment tails device, the solar energy tail device be it is domestic first completely need not
Instrument is tailed in the solar space positioning of computer software, and precision is high, but expensive.
According to test, in solar panel array, using automatic tracking system generating equipment than solid under the same terms
The generated energy for determining generating equipment improves 35% or so.But in different seasons, area and period intensity of illumination always not
Disconnected change, so how solar panel to follow sun direct projection automatically all the time to ensure expeditiously to utilize the sun
Can, it is 21 century major issue urgently to be resolved hurrily, this collection to solar energy and higher requirement is proposed using device.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of small-sized solar tracking system, the existing sun is solved
Can tracker it is expensive, it is inconvenient mobile the problems such as.
