What Are The Advantages And Disadvantages Of Solar Street Lights?

With the increasing poverty of the earth's resources, the investment cost of basic energy is climbing higher and higher, and various safety and pollution hazards can be described as ubiquitous, solar street lights as a kind of "inexhaustible, inexhaustible" safety, environmental protection of new energy is more and more attention. At the same time, with the development and progress of solar photovoltaic technology, Solar Street Light products in the environmental protection and energy saving double advantage, solar Street Light in the field of street lighting development has become more and more perfect. However, in addition to the advantages of solar street lights, there are also certain disadvantages, so what are the advantages and disadvantages of solar street lights? The following are the advantages and disadvantages of solar street lights?
Advantages of using lithium battery for solar street light
1, Lithium batteries are small in size, light in weight, easy to transport. The same power solar energy storage system used in street lights and lead-acid colloidal battery comparison, about one-third of the weight, about one-third of the volume. In this way, the transport is easier, the cost of transport naturally fell.
2, Lithium battery energy density is high, the use of longer life. Energy density refers to the storage of energy in a certain unit of space or mass is known. The greater the energy density of the battery, the more power stored in a unit of weight or volume. Many factors affect the service life of lithium batteries, and energy density is one of the very important internal factors.
3, The use of lithium battery solar street light installation convenience. Traditional solar street light installation needs to set aside a battery pit, with buried boxes to put the battery in sealed. And lithium solar street light installation to be much more convenient, can be directly lithium battery installation in the bracket, the use of hanging or built-in type.
4, Lithium solar street light repair convenience. Lithium solar street light in the repair only need to take out the battery from the pole or battery plate, while the traditional solar street light in the repair needs to dig out the buried battery, and lithium solar street light compared to the tedious much.
Disadvantages
Dispersion: the total amount of solar radiation reaching the Earth's surface, although large, has a very low density of energy flows. On average, near the Tropic of Cancer, the irradiance of solar radiation is greatest at midday in summer, when the weather is relatively clear, and the solar energy received over an area of 1 square metre perpendicular to the direction of the sun's rays averages around 1,000 W; if averaged day and night throughout the year, it is only around 200 W. In winter, it is roughly half that, and on cloudy days it is generally only around 1/5 that. In winter it is roughly half that amount, and on cloudy days it is generally only about 1/5 of that amount, which is a very low density of energy flow. Therefore, when using solar energy, to get a certain conversion power, it often requires a set of collection and conversion equipment with a considerable area and a high cost.
Instability: Due to the constraints of natural conditions such as day and night, season, geographical latitude and altitude, as well as random factors such as sunshine, cloudiness, clouds and rain, the solar irradiance reaching a given surface is both intermittent and highly unstable, which makes the large-scale application of solar energy more difficult. In order to make solar energy a continuous and stable source of energy, and thus ultimately an alternative source of energy that can compete with conventional energy sources, the problem of energy storage, i.e. storing as much of the sun's radiant energy as possible during the clear day for use at night or on rainy days, must be well addressed, but energy storage is also one of the weaker aspects of solar energy use.
Low efficiency and high costs: and the level of development of solar energy utilisation, some aspects are theoretically feasible and technically mature. However, there are solar energy utilisation devices that are not yet economically competitive with conventional energy sources because of their low efficiency and high costs in general. For a considerable period of time in the future, the further development of solar energy utilisation is mainly constrained by the economics.
The above advantages and disadvantages of solar street lights are shared here, in general, solar street lights are excellent products for developing and using solar energy, although it still has some defects, but with the progress of technology, solar street lights will definitely get better and better, bringing a comfortable and safe life to everyone.
