Installation contrast
When installing the solar street lamp, there is no need to install complicated lines, only a cement base and a battery pit within 1 m can be fixed with galvanized bolts.
There are complicated operation procedures in the construction of city circuit lights. First of all, it is necessary to install auxiliary cables, trench and pipe distribution, pipeline crossing, backfilling and other large-scale civil construction, which consumes a lot of manpower, material and financial resources. Finally, we need to debug, once there is a problem, it will cause a lot of consumption.
Cost comparison
Solar street lamp investment, long-term benefits, because the line is simple, does not produce maintenance costs, does not produce expensive electricity. Cost recovery in 6-7 years, saving more than 1 million electricity and maintenance costs in the next 3-4 years.
The city electric circuit lamp is expensive and the circuit is complex, which requires long-term and uninterrupted maintenance of the circuit. In the case of unstable voltage, sodium lamp is unavoidable to be damaged. With the prolongation of service life, the line aging and maintenance costs are increasing year by year.
Security comparison
Solar street lamp is an ideal product of ecological district and road administration department because of its 12-24V low voltage, stable voltage, reliable operation and no potential safety hazard.
There are many hidden dangers in the safety of city circuit lights. Under the changing circumstances of people's living environment, there are many hidden dangers in road reconstruction, landscape engineering construction, abnormal power supply, water and gas pipeline cross-construction and so on.
Environmental comparison
Solar street lamp can add new selling points for the development and promotion of noble ecological community, reduce the cost of property management and reduce the cost of public share of owner. In conclusion, the inherent characteristics of solar lighting, such as safety, energy saving, no consumption, green environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious advantages to the sales of buildings and the construction of municipal engineering.
Life comparison
The life of solar lamps is much longer than that of ordinary electric lamps, such as solar cell components, which are the main components of solar lamps, for 25 years; low-voltage sodium lamps, which have an average life of 18,000 hours; low-voltage, high-efficiency, three-primary energy-saving lamps, which have an average life of 6,000 hours; ultra-bright LED, which has an average life of more than 50,000 hours; and solar battery, which has a life of less than 38 AH. 2-5 years; 38-150 AH 3-7 years. According to the regulation of the local price bureau that the maintenance fee of street lamp is 6 yuan /, according to the pure residential building area, the initial investment of ordinary lamps is much higher than the initial investment of solar lamps. In a word, the characteristics of saving investment of solar lamps are quite obvious by comprehensive comparison.
In the solar power supply system, the performance of storage battery directly affects the comprehensive cost, operation and service life of the system. In this scheme, the latest energy storage colloidal battery developed jointly by the company and the Metal Research Institute of the Chinese Academy of Sciences is selected. Compared with ordinary lead-acid battery, it has the following outstanding characteristics in design and manufacturing process.
Ultra-long service life, normal service life of five to ten years.
The battery is more suitable for the cyclic charging and discharging characteristics of energy storage battery by adopting suitable positive and negative alloy formula and active material ratio.
The design of colloidal electrolyte can effectively inhibit the rust removal of active substances and sulfation of plates, thus delaying the performance degradation of batteries in use. The cycle life of the battery is greatly improved.
Select the fourth generation lighting products LED light source.
