Third, the installation of solar street lights
⒈ determine the location of the lamp; survey geological conditions, if the surface 1 m 2 are soft soil, then the excavation depth should be deepened; at the same time to confirm the excavation location below no other facilities (such as cables, pipes, etc.), the top of the street lights for a long time Shade objects, otherwise the appropriate replacement position.
⒉ in the position of the lamp set aside (excavation) meet the standard 1 m 3 pit; The embedded parts are placed in the middle of the square pit, one end of the PVC threading pipe is placed in the middle of the embedded part, and the other end is placed in the battery storage place. Pay attention to keep the embedded parts, the foundation and the original surface in the same level (or the top of the screw and the original surface in the same level, depending on the needs of the venue), one side and the road parallel; this can ensure that the poles stand upright Not skewed. And then to C20 concrete pouring fixed, pouring process to stop the vibration of vibration, to ensure the overall compactness, firmness.
⒊ construction is completed, the timely clean up the residue on the plate residue, and waste oil to clean the impurities on the bolt.
⒋ concrete solidification process, to regular watering conservation; to be completely solidified concrete (usually more than 72 hours), in order to install chandeliers.
Battery pack installation
⒈ solar panel output positive and negative in the connection to the controller before taking measures to avoid shorting;
⒉ solar cell components and stent connection to be solid and reliable;
⒊ components of the output line should be avoided exposed, and tie with tie;
⒋ the direction of the battery components to the south, to the compass point prevail.
⒈ battery placed in the control box to be lightly to prevent smashing control box;
⒉ batteries between the cable must be bolted to the battery terminal and the use of copper gasket to enhance the conductivity;
⒊ output line connected to the battery in any case to prohibit short, to avoid damage to the battery;
⒋ battery output line and the controller within the poles must be connected through the PVC threading tube;
⒌ after the completion of the above, check the controller side of the wiring to prevent short circuit. After normal shut the door of the control box
⒈ fixed parts of the various components: the sun board fixed in the sun board bracket, the lamp holder fixed to the pick arm, and then the bracket and the arm fixed to the main pole, and the cable into the control box (battery box).
⒉ light pole before lifting, first check the various parts of the fasteners are solid, the lamp is correct installation, light source work is normal. And then in the simple debugging system work is normal; release the controller on the sun board cable, light source work.
⒊ the main pole when lifting, pay attention to safety precautions; screws absolutely tight, such as the composition of the angle of the sunset deviation, you need to adjust the direction of its upward direction towards the straight south.
⒋ the battery into the battery box, in accordance with the technical requirements of the connection cable connected to the controller; first take the battery, then load, and then then the sun board; wiring operation must pay attention to the wiring and the controller marked on the terminal can not Wrong, positive and negative polarity can not crash, can not be reversed; otherwise the controller will be damaged.
⒌ debugging system work is normal; release the controller on the solar panel cable, light; connected to the sun board cable, lights off; at the same time carefully observe the controller on the changes in the lights; all belong to normal, box.
Fourth, solar street lights and conventional street lamps comparative analysis
1. Installation contrast
Solar street light installation, do not have a complex line, only a cement base and within 1m to do a battery pit, with galvanized bolts can be fixed. There are complicated operating procedures in the construction of city street lamps. First of all, to support the cable, trenching pipe, pipe threading, backfill and other large number of civil construction, consumption of a lot of manpower, material and financial resources. And finally to debug, in the event of a problem, it caused a lot of consumption.
2. Cost comparison
Solar street lights an investment, long-term benefit, because the line is simple, does not produce maintenance costs, do not produce expensive electricity. 6-7 years to recover the cost, after 3-4 years to save more than 100 million of electricity and maintenance costs. City circuit lights high electricity, line complex, long-term uninterrupted on the line for maintenance. Especially in the case of unstable voltage, sodium lamp is easy to be inevitable, and with the extension of the age, line aging, maintenance costs are increasing year after year.
3. Safe contrast
Solar street lights as a result of the use of 12-24V low voltage, voltage stability, reliable operation, there is no security risks, is the ecological community, the road sector ideal product. City road lights safety risks, people's living environment in the changing circumstances, road reconstruction, landscape engineering construction, power supply is not normal, water gas pipeline cross construction and many other risks.
4. Environmental comparison
Solar street lights for the development and promotion of noble ecological community to add new selling points; sustainable reduction of property management costs, reduce the cost of the owners of the public part of the apportionment. In view of the comparison, the safety of solar lighting without hidden danger, no energy consumption, green, easy installation, automatic maintenance and maintenance of the inherent characteristics of the sale of real estate, municipal construction directly bring the obvious advantages.
5. Life contrast
The life of solar lamps is much higher than that of ordinary electric lighting fixtures, such as the main components of solar lamps ---- 25 years of life of solar modules; low-pressure sodium lamp average life of 18,000 hours; low-pressure high efficiency three primary color energy-saving lamps average Life of 6000 hours; super bright LED average life expectancy of more than 50,000 hours; solar dedicated battery life of 38AH the following 2-5 years; 38-150AH 3-7 years. In accordance with the conventional district in accordance with the local price bureau "by the pure residential building area of a one-time collection of street lights maintenance fee 6 yuan / ㎡" requirement, making the initial investment in general lighting to be higher than the initial investment in solar lighting. In short, a comprehensive comparison of solar energy lamps to save investment characteristics is quite obvious.
