Concentrating photovoltaic and temperature difference compound street lamp power supply system

Abstract

The invention discloses a concentrating photovoltaic and temperature difference compound street lamp power supply system. The concentrating photovoltaic and temperature difference compound street lamp power supply system comprises a fresnel collecting lens, a gallium arsenide solar panel, a thermoelectric power generation chip, cooling fins, a servo motor, a PLC and a light dependent resistor component. According to the concentrating photovoltaic and temperature difference compound street lamp power supply system, sunlight is collected to the gallium arsenide solar panel through the fresnel collecting lens, then the thermoelectric power generation chip attached to the back of the gallium arsenide solar panel is used for cooling the gallium arsenide solar panel, the generating efficiency of the gallium arsenide solar panel is improved, waste heat is converted into electric energy through the thermoelectric power generation chip, a sunlight tracking system composed of the Delta PLC guarantees that the power generation system is in a perpendicular incidence state all the time, the generating efficiency of the whole system is greatly improved, and a field power supply system is formed through an intelligent charging and discharging system. The overall efficiency of the concentrating photovoltaic and temperature difference compound street lamp power supply system is substantially improved, the efficiency can be 50%, the power supply system can be combined in a networking mode, an inverter is additionally arranged, and the power supply system is connected to a mains supply grid.

Description

technical field [0001] The invention belongs to the technical field of new energy sources, and in particular relates to a power supply system for a concentrated photovoltaic temperature difference composite street lamp. Background technique [0002] Solar energy is a clean and renewable new energy source, which is more and more favored by people and has a wide range of functions in people's life and work. One of these is the conversion of solar energy into electricity, and solar cells use solar energy to work. The working principle of a solar thermal power station is to use the concentrated sunlight to boil water until it turns into water vapor, which is then used to generate electricity. [0003] The energy of solar energy is the energy (mainly solar energy) from celestial bodies outside the earth. It is the huge energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperature. Most of the energy needed by human beings comes directly or indirectly from...
