Solar led street light, solar led street lamp to introduce the advantages and disadvantages

Solar led street lamp, led solar street light 

 

Energy is an important guarantee of social and economic development, vigorously develop renewable energy is the main way to solve the energy crisis. As people living standard rise, the growth of awareness of environmental protection, emphasis on sustainable development and human body health, enlarged the human to pollution-free, environmental protection and energy saving lamps and lanterns of demand. 

 

Solar led street lamp, led solar street light 

 

1. LED solar street lamps using solar photovoltaic battery power, new energy, solar energy as a kind of green environmental protection "limitless reserve, using them all". Make full use of solar energy resources, to relieve the tense situation of conventional energy have positive significance. 

 

2. LED solar street lamps, installation is simple, convenient, need not like ordinary street lamp do laying cable, such as a large number of foundation engineering, only need to have a fixed base, all the lines and control parts are placed in the lamp, to form a whole. 

 

3. The LED solar street light running low maintenance costs. The whole system running are automatic control, without human intervention, almost do not produce maintenance costs. 

 

Solar led street lamp, led solar street light shortcomings 

 

Dispersion: to the amount of solar radiation on the surface of the earth although is very big, but can flow density is very low. On average, near the tropic of cancer, in summer the weather is sunny, noon irradiance of solar radiation, the largest in the direction perpendicular to the sunlight 1 square meter area receives an average of about 1000 W solar power; If according to the annual average day and night, only about 200 w. And in the winter only roughly half, cloudy day only 1/5 or so commonly, this energy flow density is very low. Therefore, in the use of solar energy, want to get a certain switching power, often require area is quite a collection and conversion equipment, cost is higher. 

 

Instability: by day and night, season, geographical latitude and altitude, and the natural conditions such as sunny, cloudy, cloud, rain, etc. The influence of random factors, therefore, has reached a certain ground the solar irradiance is intermittent, it is unstable, this increases the difficulty to the mass of solar energy application. Continuous and stable in order to make solar energy, and eventually be able to compete with conventional energy alternatives, it is necessary to well solve the problem of energy storage, namely the sunny during the day the sun radiant energy stored as far as possible, for the night or rainy day, but the energy storage is one of the relatively weak link in solar energy utilization. 

 

Low efficiency and high cost, and the development level of solar energy utilization, some aspects is feasible in theory, technology is mature. But some solar energy utilization device, because of low efficiency, high cost, in general, economy also can‘t compete with conventional energy. In quite some time in the future, the further development of solar energy utilization, is mainly restricted by economy. 

 

Above is the small make up to introduce some basic information about solar led street light and solar led street light some of the advantages and disadvantages, we can see that our solar led street lamp advantage is obvious, but can‘t rule out some shortcomings, so according to the actual situation of each region to install proper street lamp.
