Solar Energy - Advantage Of Solar Street Lights
By:Jimmy Wang

Solar Energy - Advantage Of Solar Street Lights
Solar energy - One of the most major energy of this century for human. By 2030, the world's electricity production will rely mainly by Solar energy. Solar energy as a non-polluting environment, but also an inexhaustible new energy will be everywhere. Solar products by light under the sun, into electricity process, is developed by means of a new high energy, mankind yearns for the 21st century, the pursuit of a new light.

Solar lights and solar power generation systems, etc. The main innovation:
An energy saving, which uses natural light, no consumption of energy, and inexhaustible not finish;
2 green, with green environmental protection requirements, no pollution, no radiation, ecological protection;
3 security, the products do not use AC power, and Solar energy absorbed by the battery, through the low-voltage direct current into light, is the most secure power supply;
4, high technology, products, core devices are intelligent controller, set the self-control, time control switch device 24 hours a day under the sky brightness and the people in a variety of environments need to automatically adjust the brightness;
5 products long life, low cost installation, and maintenance.

Advantages solar street lights
As the Earth's resources become increasingly scarce, increasingly based on investment costs of energy rising, and a variety of safety and pollution problems can be said to be everywhere. Solar energy as a "inexhaustible" security, environmental protection and new energy sources more and more attention. Thus, solar water heaters with solar lighting products came into being after the popular, where the solar street lamps and light effects in using the circuit for practical comparison.
A comparison:
City street lighting installed power complex: electric lighting in the city street project in the complex operating procedures, first laying cable, here would be the cable trench excavation, laying of underground pipe, pipe threading, filling large number of foundation engineering. Then a long period of installation and commissioning, if any of the lines in question, will have to rework large areas. And complex terrain and line requirements, the high cost of labor and supporting materials. Easy to install solar lights: solar street light installation, do not lay a complex line, so long as to make a cement base, and then you can use stainless steel screws.
Contrast 2:
Mains electricity lighting the high street: street lighting electricity work has a fixed high tariffs, a long-term continuous and other configurations on the line for maintenance or replacement, maintenance costs increase every year. Solar Road Lamp-free electricity: solar street lamp is a one-time investment, no maintenance cost, investment cost recovery for three years, long-term benefit.
Contrast 3:
City Electric Lighting lamps pose a safety hazard: street lighting electricity due to construction quality, the transformation of landscape engineering, materials aging, power supply not normal, water and electricity pipes and other aspects of the conflict bring many security risks.
Solar lights are safe is: ultra-low voltage products solar street lamp is safe and reliable operation. Other advantages of solar lights: green, high ecological community for the development and promotion of the addition of new selling point; sustainable reduce property management costs, reduce the cost of some of the owners of public sharing.
In summary comparison above, no hidden solar security lights, no consumption of energy-saving, environmental protection, ease of installation, maintenance and other automatic features, will be the sale of real estate, municipal construction projects can be used directly to bring obvious advantages.

Solar street light consists of the following components: solar cells, batteries, solar street light special controller, light and lamp post. Is an automatic control system of work, simply set the mode of the system will automatically work. Solar street lamp is ideal for road lighting, along with the improvement of people's lives and the continuous development of society, it will be widely used to give the earth the sun the bright lighting at night for the man.
