Solar street lighting system design
1.0 Overview
Nowadays, solar energy has become a recognized green energy and has been gradually applied to people's livelihood for the benefit of mankind. One of the solar garden lights solar energy is a kind of application, relying on the solar radiation during the day solar photovoltaic components and generate electricity, and the generated electricity delivered to the battery for storage. Night when the light down to a certain extent or reach a certain point of time, through the controller control, so that the battery discharge of light appliances. Until the illumination rises to a certain extent or at a certain moment, automatically turn off the electricity.
2.0 system design
Solar street lights mainly by the solar module, module bracket, electric control box (built-in controller, battery), light pole (including lamps) and other parts. System diagram as shown below:

2.1 system settings
The system uses the area as **, the average standard light hours is 4.46 hours. Set the system to work 8 hours a day, a continuous monthly rainy days for 5 days, every two consecutive rainy days interval of 20 days.
2.2 design process
The system design process includes: light pole selection, lighting selection, solar module configuration, battery, controller configuration, system protection settings.
3.0 light pole selection
Pole is the supporting part of the street lamp, and has high requirements on its hardness, height, wind resistance and corrosion resistance. Nowadays, the commonly used material is Q235, which is processed through a series of processes, and the surface is coated with 80μm coating.
The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.
