At first, expanded the application of solar energy power generating.Traditional solar power generation mainly is installed in the roof, ground and curtain wall (BIPV).But roof resource-constrained.The soil of developed area is mainly used in agricultural planting and urbanization development, and population is on the increase, and the contradiction of having a large population and a few land is more and more outstanding.Be installed on desert or desert area, not only away from the electricity consumption area, sizable electric energy is lost in the long distance powedr transmission meeting, and safeguards the generating more complicated, cleans and relatively is stranded ability.The hydrosphere area takes up an area of 70.8% of ball surface area according to statistics, and the utility model is applied to the vast water surface of area with solar energy power generating, has expanded the application of solar energy power generating.

Secondly, improved generating efficiency.Crystal silicon cell in use has overheated problem, can influence generating efficiency.The utility model floats on the water surface, because the water-cooled effect, energy output is higher by 1% than traditional ground type.Water channel, lake, reservoir in densely populated areas are laid this electricity generation system, near the area of electricity needs, have reduced the loss of electric power in the transmission of electricity process, have improved the service efficiency of electric power.

At last, the utility model helps safeguarding.The utility model directly is layed on the water surface, directly water cleaning solar energy cell plate.Dust can let solar panel dirty, influences the efficient of solar power generation, therefore needs regular cleaning solar energy cell plate.For the earthbound solar energy cell panel, it is higher to clean cost, and the utility model is the water source of using system below directly.

In a word, the utility model is made up of plurality of sub arrays, and each subarray all is made up of buoyancy aid, module frame, solar-energy photo-voltaic cell module and Circuits System.Each subarray is by series connection of solar-energy photo-voltaic cell module process and parallel connection according to actual needs; Be connected in the header box, and connect the certain protection device, each subarray is by one or some inverter controls; The electric power that produces directly is connected to the grid, and perhaps uses nearby.The solar cell module is fixedly mounted on the buoyancy aid frame, makes whole system to swim in more than the water surface and generates electricity.Whole system adopts new material, waterproof, and anticorrosive, in light weight, intensity is big.Adopt the standardized module structure, easy for installation, standardized production helps the large-scale commercial applications application.
