As a new energy source in the 21st century, what are the specific advantages of solar streetlights compared to ordinary traditional streetlights?

1. Installation comparison.

General lighting street light installation is complex: in general lighting street light project there are complex operating procedures, first of all to lay the cable, cable trench excavation, laying concealed pipe, pipe threading, backfill and a lot of other basic works. Then a long period of installation and commissioning, such as any one line has a problem, it is necessary to rework a large area. And the terrain and line requirements are complex, with high labour and auxiliary material costs. Solar street light installation is easy: solar street light installation without laying complex lines, just make a cement base, and then fixed with stainless steel screws can be.

2. Cost comparison.

Solar street lights are a one-time investment, long-term benefits, due to simple lines, no maintenance costs, no expensive electricity costs. 6-7 years to recover costs, after 3-4 years to save more than 1 million of electricity and maintenance costs.

Municipal street lights have high electricity costs, complex lines and require long-term uninterrupted maintenance of the lines. Especially in the case of unstable voltage, the sodium lamp is inevitable, and with the extension of the years, the line aging, maintenance costs are increasing year after year.

3. Safety comparison.

Solar street light is an ideal product for ecological communities and road authorities due to the use of 12-24V low voltage, stable voltage, reliable operation and no safety hazards.

Municipal electric street lights have big safety hazards, people's living environment in the case of constant changes, road renovation, construction of landscape projects, irregular power supply, cross construction of water and gas pipelines and many other aspects bring many hidden dangers.

4. Environmental comparison.

Solar street lights can add new selling points to the development and promotion of noble ecological communities; they can sustainably reduce property management costs and reduce the cost of the owners' public share. In summary, the inherent characteristics of solar lighting such as safety without hidden dangers, energy saving without consumption, green environment protection, easy installation, automatic control and maintenance-free will bring obvious advantages to the sales of properties and construction of municipal projects directly.

5. Lifespan comparison.

The life span of solar lamps and lanterns is much higher than that of ordinary electric lamps and lanterns. For example, the life span of the main components of solar lamps and lanterns ---- is 25 years; the average life span of low pressure sodium lamps is 18,000 hours; the average life span of low pressure high efficiency trichromatic energy saving lamps is 6,000 hours; the average life span of super bright LEDs is more than 50,000 hours; the life span of special batteries for solar energy is 2-5 years for less than 38AH; 3-7 years for 38-150AH. According to the conventional district in accordance with the local price bureau "according to the pure residential building area of a one-time charge district street light maintenance fee of 6 yuan / ㎡" provisions, making ordinary lamps and lanterns initial investment to be much higher than the initial investment in solar lamps and lanterns. In short, a comprehensive comparison of the investment-saving features of solar lamps and lanterns is quite obvious.
