Embodiment Construction

[0009] The principle of the solar photovoltaic power generation system of the present invention is as follows: figure 1 As shown in the solar photovoltaic power generation system, the solar cells are connected to the controller, and the output end of the controller is connected to a DC load; the output end of the controller is also connected to an AC load through an inverter, and the controller is connected to a battery pack, and the solar cells are polycrystalline silicon solar cells. The battery pack is a sealed maintenance-free lead-acid battery. The photovoltaic system is composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC power distribution cabinets, automatic solar tracking systems, automatic solar module dust removal systems and other equipment. The function of each part of the equipment is: Solar cell square array: In the case of light (whether it is sunlight or light produced by other luminous bodies), the battery absorbs ligh...

Abstract

The invention discloses a solar photovoltaic power generation system. A solar cell is connected with a controller, and the output end of the controller is connected with a direct current load and is also connected with an alternating current load through an inverter, and the controller is connected with a storage cell bank. According to the solar photovoltaic power generation system, a certain electromotive force is produced by solar cell assemblies under the illumination condition, and a solar cell square array is formed by the serial-parallel connection of the assemblies, and the voltage of the square array meets the requirement on the input voltage of the system. A storage cell is charged by a charge-discharge controller. The storage cell bank provides input current for the inverter at night, and direct current is converted into alternating current under the action of the inverter, and the alternating current is conveyed to a power distribution cabinet. The discharge condition of the storage cell bank is controlled by the controller, and the normal use of the storage cell is guaranteed. A photovoltaic power station system is required to be provided with a load limiting protection and a lightning protection device, so that the overload operation of system equipment is protected, and the system equipment is protected from lightning strokes, and the safe use of the system equipment is maintained.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a system for generating power by solar power. Background technique [0002] As an environmentally friendly resource, solar energy has been more and more widely developed and applied. Solar energy is not only a primary energy source, but also a renewable energy source. It is rich in resources, can be used for free, does not need to be transported, and has no pollution to the environment. It has created a new life form for human beings, and brought society and human beings into an era of saving energy and reducing pollution. It is generally used for power generation in modern times. Solar power generation is a new type of renewable energy. The use of solar energy is not very popular yet. There are still problems of high cost and low conversion efficiency in the use of solar power generation, so it cannot be widely used. Contents of the invention [0003] In orde...
