Why is solar energy street light more than the circuit?

Solar street lamps in rural highways, tourist attractions, lighting, remote mountainous area and the regional economy is not rich and power supply is hard to reach places, it rely on the wire, might as well complete self-sufficiency in power supply, has a high economic benefit and social benefit.

in rural highways, tourist attractions, solar street lamps, lighting, remote mountainous area and the regional economy is not rich and power supply is hard to reach places, which rely on the wire, might as well complete self-sufficiency in power supply, has a high economic benefit and social benefit. For less than he did not spread to the sunshine. Some places with buried pipes, capital will be higher, unusual lights sent late, the mistake in the installation model of heavy and complicated, needs laying cable, to implement in cable trench excavation, buried pipeline and line. But also have solar street lamps, rainy day lighting problem who also dare not guaranteeing, battery life, etc. Manipulation of solar power, LED street lamp, incomparable clarity, the height of peace, relatively broad and abundant resources, long life and love and sex, the benefits of what the rest of the practice such as resource does not have solar resource is thought to be the 21st century the most important new resources. As a new type of dynamic lighting, solar street lamps to handle our country, it is a solar power supply, when the sun during the day time, will open the solar energy circuit board, for the battery solar street lamps, and then it is still night, the night or will open a battery-powered lights. But follow the enterprising skills, these problems will soon be processing, not by the fallout from the sky, but the late capital will gradually recover. Lamp life is longer than mains street lamp, solar street lamps embedded wire has a safe hidden trouble, if others in place for embedded wire construction, could damage to the line pipe, simple form ping an incident. Solar street lamps trust will rise and replacement of rising mains streetlights, become the king of the road, street capital relatively slightly lower, electricity prices follow the price rises, power station also asserts itself in the poor planning, also often on line for nursing care.
