LED solar street lighting development affected by what?

Introduction: in the major cities in China, the traditional power street lamp is still the absolute protagonist.

Do not consume electricity, without laying lines, just a solar panel, you can light up the city's night. Once upon a time, LED solar street lights quietly appeared in some urban streets. However, this environmentally friendly street lights always free in the mainstream edge. In the major cities in China, the traditional power street lamp is still the absolute protagonist. Recently, the Internet rumors that a message is causing strong concern. The message said: a unit of an account, the installation of a LED solar street lamp takes 100 years to recover the cost. Is that true? Why is it difficult to popularize LED solar street lights?

Wuhan, a park that solar street lamps can save a lot of money, but later found that after accounting is not the case. In September 2006, the park has installed more than and 200 solar street lamp LED, when the average per lamp installation fee of about 10 thousand yuan. The park is only 4 hours per night lighting, if the installation of ordinary lights of 20 watts, the total annual consumption of each lamp is about 29 degrees. According to 1 yuan per kilowatt hour of electricity, the annual electricity tariff per lamp is $29. Calculate, this is a solar street lamp can save the cost of a year. As a result, only 10 thousand yuan fee was invested, the installation of a solar street will be used continuously for 300 years to break even. Today, the cost of each lamp down to 3000 yuan, also have to take back the cost of 100 years. Even if the lighting time is extended to 8 hours a day, have to be used for a continuous period of 50 years. Although the LED solar street lights do not have electricity, but the battery board needs to be replaced 3-5 years. Batch replacement battery board, but also a small investment.

As a result, some of the solar lights in the park later broke down, and the park was no longer maintained or replaced because of economic reasons. In April 2009, Wuhan Hankou beach had installed the part of "complementary scenery" street, then became a unique landscape. Soon, the city also installed several other wind or solar street lights. However, some people complain that these lights are not bright, basically do not play the role of lighting.

In this regard, the construction side has said that the current level of technology, new energy lamp depends on wind and solar energy and other natural resources is very high, plus the lamp is cold light, compared with the traditional street lamps, there will be differences in the effect of natural lighting. Who is not willing to be named Street Department staff bluntly: now it seems that the original installation of those solar street lights, is the failure of the street lamp, did not achieve the desired results.

Insiders: normal 10 years recoverable costs

The day before, insiders told reporters, LED solar street "said the Internet back to hundreds of years of cost", mainly for non formal purchase or expensive purchase, normally about 10 years to recover the cost. He told reporters that the Internet solar street lights, said to be able to recover the cost of hundreds of years, mainly for informal procurement or high priced procurement. Sun Maoqin said: normal 10 years or so recoverable costs. Sun Maoqin said that the current market price of a solar street is about 3000 yuan, you can use the rain in the sky for 7 days. In maintenance, the main is to replace the battery, a battery at the cost of 600 yuan, the battery product quality is not good or even 1 years to be replaced, if all change is not a small expenditure.

Status: popularization and promotion of difficulties

Insiders pointed out that the solar street lights can not be on the road situation, involving policy issues, promotion strategies, consumer attitudes, etc.. The Wuhan street management, solar street lamps on energy saving and environmental protection advantages, but practicality is not strong, the initial investment is too large, high maintenance cost, immature technology and other factors, the current in the promotion suffered a bottleneck. However, the reporter learned from a number of solar street manufacturers in Jiangxi, the current price of solar street lights to drop down a lot, and the replacement of the battery is not like a network of rumors to replace a thousand dollars. Wuhan, a sales consultant, said the introduction of photovoltaic enterprises, solar street lamps can generally use 3-5 years, depending on the size of the battery capacity is different, the price is also different. A solar energy technology company in Jiangxi, Ganzhou, said they were able to recycle old solar cells, three years later, only need to add more than $200 to replace the new battery. "If it is the dealer, they certainly can not be recycled, so the maintenance costs should be higher than many. The company's sales staff said.
