Efficient and safe solar power generation device
Technical Field
The utility model relates to a solar energy power generation technical field, in particular to high-efficient safe solar power system.
Background
As society develops, human energy consumption is also increasing, and at present, fossil fuels are mainly consumed, but the resources of the fossil fuels are limited, and pollution gas is also generated in the combustion process of the fossil fuels. Because the solar photovoltaic power generation has the advantages of no pollution, universality and inexhaustibility of resources and the like, the solar energy meets the requirements of environmental protection and sustainable development, so the application of the solar photovoltaic power generation is more and more extensive at present and is in continuous scale.
Solar energy is widespread and free, but the cost of solar power plants is relatively high. At present, solar power generation equipment is generally installed in a place with good light radiation intensity and open space, so that the solar power generation equipment not only can easily receive more light, but also can be interfered by the outside as much as possible. For China, the illumination intensity in the northwest, the southwest and other areas is high, the total amount of solar radiation is large, and the solar radiation can be well utilized.
However, on the one hand, the sun's illumination angle changes from time to time in the process of sunrise to sunset due to the rotation of the earth, and when the incident angle of the light and the solar panel are large, the solar power generation efficiency is low, and the low efficiency is not favorable for the maximization of resource utilization compared with the high equipment cost. Therefore, it is very helpful to control the utilization rate of solar energy and the cost if the power generation efficiency can be maximized as much as possible by changing the incident angle of the solar light to the solar cell panel.
On the other hand, solar energy equipment is usually in open places such as northwest areas of China, and in the places, the solar energy equipment is inevitably subjected to larger wind force influence. When the wind power is too large, if the angle of the solar cell panel is not adjusted, damage is easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, and in particular provides a high-efficient safe solar power system. The above problems are mainly related to: firstly, most photovoltaic power generation solar panels are fixed, so that the light receiving efficiency of the solar panels is limited, the generated energy of unit equipment is not beneficial to improvement, and secondly, the fixed structure cannot flexibly deal with the potential damage of larger wind power to the equipment.
The power generation device improved by the scheme can track the position of the sun in real time in one day, and adjust the light incidence angle according to the position of the sun, so that the power generation efficiency of the whole power generation device is higher as much as possible; in addition, the solar panel on the power generation device can be adjusted to be in a proper state according to the potential threat of the wind power in the case of overlarge wind power, so that the damage of the solar panel and other components caused by the strong wind power can be reduced as much as possible.
A solar cell panel can adjust a certain angle of the solar cell panel according to an illumination angle, so that the efficiency of the solar cell panel is improved, solar energy is fully utilized, and efficient clean energy is provided. That is to say, the device that this scheme provided can make solar cell panel track the position of sun and control solar panel automatic rotation constantly in one day, and under the too big condition of wind-force, solar cell panel stops to track the rotation to this protection panel subassembly and make solar energy fully utilize, provide more efficient clean energy.
