Problems solved by technology
The existing solar power generation has the following deficiencies: First, the electric energy converted by the photovoltaic panels during the day needs to be stored in lead-acid batteries before being supplied to users for use at night. A large number of lead-acid batteries are used, and the cost is high, and the waste of lead-acid batteries is Acid batteries are very polluting to the environment. In addition, through storage and discharge of batteries, energy loss is large, which further increases production costs; Inefficient power generation

Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0017] Such as figure 1 Shown: Solar energy global grid-connected power generation system, including several photovoltaic panels 1, a controller 2 connected to the photovoltaic panels 1, a grid-connected inverter 3 connected to the controller 2 and load 5, and connected to the photovoltaic panels 1 , the cable 4 of the controller 2 and the inverter 3 . The electric energy generated by the photovoltaic panel 1 is directly input into the grid to supply the load 5, eliminating the need to configure the battery, saving the process of storing and releasing the energy of the battery, improving the use efficiency of electric energy, reducing energy loss, reducing system cost and avoiding Pollution from waste lead-acid batteries.
[0018] The system covers the whole world, interconnects the whole world as a unified body, and transmits the electric energy t...

The invention relates to a solar global grid-connected power generation system, and belongs to the technical field of electric power. The system comprises a plurality of photovoltaic panels 1, a controller 2 connected with the photovoltaic panels 1, a grid-connected inverter 3 connected with the controller 2 and a load 5, and cables 4 connected with the photovoltaic panels 1, the controller 2 and the inverter 3. The system covers all over the world, and carries out interconnection and grid connection with the global being as a unity. The system enables the electric energy generated by the photovoltaic panels to be directly input to a power grid to provide energy for the load instead of being stored in a storage battery, thereby avoiding arrangement of the storage battery, avoiding the storage battery energy storage and release process, improving use efficiency of the electric energy, reducing energy loss, reducing system cost and meanwhile, reducing final pollution; and the system enables the electric energy generated in places in the daytime to be transmitted to places at night in real time for use, so that the system is high in power generation efficiency, wide in use area and good in economic benefit.
Description
technical field [0001] The invention relates to a solar energy global grid-connected power generation system, which belongs to the field of electric power technology. Background technique [0002] With the development of the economy and the progress of society, people put forward higher and higher requirements for energy, and finding new energy has become an urgent issue facing mankind. There are three main sources of existing electric energy, namely thermal power, hydropower and nuclear power. In addition to its high cost, it also has the following disadvantages: [0003] Thermal power needs to burn fossil fuels such as coal and oil. On the one hand, the reserves of fossil fuels are limited, they are burning less and less, and are facing the danger of depletion. It is estimated that the world's oil resources will be exhausted in another 30 years. On the other hand, combustion will emit carbon dioxide and sulfur oxides, which will cause the greenhouse effect and acid rai...
