1. Easy to install: Solar street lights when installed, do not have to be supplemented with complex lines, only to do a cement base, do a battery pit, with galvanized bolts fixed can be.
Do not need to consume a lot of human, material, financial consumption, installation simple, do not need to line or "RIP belly" excavation construction, there is no power outage limit concern.
2. Less investment: Solar street lights an investment, long-term benefits, because the line is simple, does not generate maintenance costs, does not produce expensive electricity charges. 6-7 years to recover costs, 3-4 years to save more than 1 million of electricity and maintenance costs. Can save the city lights high electricity charges, complex lines, the need for long-term uninterrupted maintenance of the line.
In the case of special voltage instability, it is inevitable that sodium lamps are prone to bad, and with the prolongation of the number of years, line aging, maintenance costs are increasing year by year.
3. Good safety performance: Solar street lights due to the use of 12-24v low pressure, voltage stability, reliable operation, there is no safety hazard, is the ecological community, the road department ideal products. No electric shock, fire and other accidents.
The safety hidden danger of the electric light street lamp is big, the people's living environment in the constantly changing situation, the road reconstruction, the landscape engineering construction, the power supply is not normal, the water gas pipeline cross-construction and so on many other hidden dangers.
4. Energy saving and environmental protection: solar photovoltaic conversion to provide electricity, inexhaustible. No pollution, no noise, no radiation. Solar street lamps can add new selling points for the development and popularization of noble ecological community, and can reduce the cost of property management and reduce the cost of the owner's public sharing part.
In contrast, the safety of solar lighting without hidden dangers, energy-saving and non-consumption, green environmental protection, easy installation, automatic control and maintenance-free and other inherent characteristics will be the sale of property, municipal engineering construction directly bring obvious advantages to be utilized.
5. Long life: The life of solar lamps is much higher than that of ordinary electric lamps, such as the main components of solar lamps----The service life of solar modules is 25 years; the average life span of low-pressure sodium lamps is 18,000 hours; the average life span of low voltage and high efficiency three-color energy-saving lamps is 6,000 hours ; The average life span of ultra-bright LEDs is more than 50,000 hours; the life of a dedicated solar battery is less than 38AH for 2-5 years; and 38-150ah 3-7 years. Product technology content is high, control system, accessories are international brand, intelligent design, reliable quality. According to the regular community according to the local price bureau "according to the pure residential building Area one-time collection of Community street lamp maintenance fee 6 yuan/square meters" provisions, so that the initial investment of ordinary lamps to be higher than the initial investment of solar lamps a lot.
In short, a comprehensive comparison to see the characteristics of solar lamps to save investment is quite obvious.
In the solar power supply system, the performance of the battery directly affects the comprehensive cost, operation and service life, the company and the Chinese Academy of Sciences Metal Research Institute jointly developed the latest results of energy storage colloidal battery, compared with the ordinary lead-acid battery, it has the following outstanding characteristics in the design and manufacturing process:
The service life is extremely long and the service life under normal conditions is 5-10 years.
The suitable formula of positive and negative pole alloy and the ratio of active substances are used to make the battery more suitable for the use of circulating charge and discharge of energy storage battery. The design of colloidal electrolyte effectively inhibits the rust of active substances and the sulfate phenomenon of plate, thus delaying the performance of the battery in the process of use failure and decline. The deep filling cycle life of the battery is greatly improved. Selection of CAP four-generation lighting products LED light source
