Theoretically, the higher the price of the product is better, but you do not know that there are a lot of links you do not know the "cats and dogs", from the following three aspects for you to analyze.

First, solar street lamp light source, lithium batteries, solar panels, the matching ratio between the three to determine the light effect of the street lamp. Solar street lamps are different from led street lamps, led street lamps light source and drive to determine the light power, while solar street lamps to determine the light power is the light source, lithium battery, solar panels with the three, a good proportion of collocation to protect the street lamps enough light power. For example: with small power solar panel with high capacity lithium batteries and high power light source, solar panel charging capacity is low, every day lithium batteries are not full of bright light effect can not be guaranteed, the parameters of the three are not good with the overall effect of bright light.

Second, the procurement of solar street lamp channels are manufacturers, trading companies, regional stores, different channels give different offers, which manufacturers give the price is zui low, followed by trading companies, zui expensive is the regional stores. With the deterioration of the competitive environment in the market, we will find that the same parameters will appear manufacturers, trading companies, regional stores to give the same price, ask whether there is no problem? I think there must be, trade companies, regional stores are from the manufacturers of goods, out of the same price can earn money? Definitely can not, then why is this? Is it that they are stupid? Definitely not. Solar street light is a relatively closed market, do not know the line of people simply do not understand the doorway, resulting in the same price out of only one reason, that is, "false standard", with the way to protect the profits of the unwritten insiders, it is because of the parameters of the reduction to cause you to spend a lot of money but to buy the reduction of the solar street light.

Third, solar street lights need maintenance, because street lights are generally used in outdoor environments, by the impact of environmental conditions in various regions will lead to some of the solar street lamps appear damaged, not timely maintenance will lead to this part of the street lamp lighting effect deteriorated or even broken. Solar street light general service life of 5-8 years, affected by environmental factors, the service life of each region will be different. Solar street light maintenance is divided into manufacturer maintenance and regional personnel maintenance, manufacturer maintenance is mainly for part of the street light brightness reduction, accessory damage, line aging and other conditions; regional personnel maintenance is mainly for the street light outside the surface cleanup, surface obstacle cleanup, accessory damage reporting. Only regular maintenance of solar street lights can guarantee the stability of solar street light effect. The following are some of the main reasons for this,

After reading my analysis I think you must have some understanding, welcome to ask more questions.
