  • The trend of integrated solar street light 2018-01-03
    The trend of integrated solar street light

    With the national new energy-saving environmental protection social recommendation, solar street lights gradually replace the city lights, this energy-saving products are very subject to people's attention, and with the development of solar street lights, integrated solar street lights are gradually being well-known, What is the integrated solar street light? It’s relative to the split solar street light, just put the battery, batteries, solar street light controller, LED light source into one, made of a lamp, and then configure the pole or pick the arm installation. What are the advantages of integrated solar street lights? This lamp is to install more convenient, it can be said to be a fool-type installation, if you can use the screw then you can installation, eliminating the need for the traditional split solar street lights need to install the battery bracket, lamp holder installation, production of battery pit and other steps, saving labor costs and construction costs. In addition, the integrated solar street lights also has the following advantages: solar energy to provide electricity conversion, inexhaustible; 2. environmental protection: no pollution, no noise, no radiation; no electric shock, fire and other accidents; 4.convenient: easy to install, do not need to wire or belly dig construction, power outage no worry; 5.long life: high technology products, control systems, accessories are international brands, intelligent design, reliable quality; 6.high grade: technology products, green energy, the use of units emphasis on science and technology, improve the green image, improve the grade; 7.less investment: one-time investment and exchange equivalent (AC investment from substation, into the power, control box, cable, engineering), an investment, long-term use; 8.Widely used: Solar energy comes from nature, so it can be used in any place with sunshine, especially for green landscape lamp, residential and outdoor lighting, coastal landscape lighting and decoration of tourist attractions, industrial development zone, street lighting for industrial and mining enterprises, Major institutions outdoor lighting

  • Whether Is Radiation At PV Power System 2017-12-19
    Whether Is Radiation At PV Power System

    1. What is electromagnetic radiation? What is radiation? It refers to the object in the form of waves or particles to the surrounding space to launch energy process. All the objects in nature as long as the temperature above absolute zero, will be in the form of electromagnetic waves or particles kept to the outside world to send energy, in other words, the world has radiation, including the body itself, all the time in the outward radiation , Such as the sun, in fact, is to accept the sun's radiation. However, not all of the radiation is harmful, and some even inseparable from it, such as the sun's radiation - the sun, the earth's growth needs all the sun. Although the electromagnetic radiation does not change the molecular nature of the organism, causing direct damage, but if the energy is large, will also have a certain impact on the organism, reflected in two aspects: thermal effects and induced current. Household equipment can also cause interference, such as cell phones, radios and televisions. 2. The generation of electromagnetic radiation According to the basic theory of electromagnetism, there will be a corresponding electric field distribution around the charged particles. The charged particles will change with time. If there is a potential difference between the two points with different potentials around the charged particles, Voltage; when a large number of charged particles move when the formation of the current, the current around the magnetic field, with the time of the current will change the magnetic field. Similarly, the time-varying magnetic field can also produce electric field, so that changes in the electric field and the magnetic field alternately generated, perpendicular to each other and continue to spread to the space, resulting in electromagnetic radiation. Electromagnetic radiation carried by the size of the energy depends on the frequency of the high and low frequency, the greater the energy. 3. Electromagnetic radiation of photovoltaic systems PV system is composed of photovoltaic modules, brackets, DC cables, inverters, AC cables, power distribution cabinets, transformers and other components, which stent is not charged, naturally does not produce electromagnetic interference. PV modules and DC cables, which are DC current, the direction does not change, can only produce electric field, can not produce magnetic field. Although the output transformer is AC, but the frequency is very low, only 50Hz, the resulting magnetic field is very low. Inverter is the DC power into the AC equipment, which has a power electronic transformation, the frequency is generally 5-20KHz, it will produce alternating electric field, it will also produce electromagnetic radiation. PV inverter as a power electronic equipment, switching frequency is higher, group string inverter is usually about 20K, the current is relatively large, if not take measures, there will be a lot of electromagnetic interference. The usual methods are shielding, fil...

  • How long can a solar street lamp be used in rural areas 2017-12-16
    How long can a solar street lamp be used in rural areas

    The state to support new energy, many parts of the country are installed solar street lights, a solar street lights can be used for how long, this is a lot of beneficiaries are most concerned about. Life and solar panels, solar controller, LED light source, the battery, the following I have to analyze the impact of solar street lights use of these factors: 1.The life of solar panels generally up to 25 years, as long as you are a regular solar panel out of the product, the life of the poles can reach more than 30 years, the use of such a long life parts, can not be considered. 2.Solar street light controller technology is now more mature, not easily broken, as long as the correct use of the instructions, will not cause much threat. Even if the failure, the price is relatively cheap, many manufacturers are common, easy ordering, maintenance is also simple. 3.LED light source and battery life, battery life, manufacturers generally promised to 3 to 5 years, but if the overall system configuration is too small, the street lights are always used in a state of loss, so that the battery will be very fast , That is, the impact of the battery life. Some may have 2 to 3 years have to be replaced once. Usually we use the battery, it is necessary to take into account the daily solar panels charge, but also consider the daily power consumption of light, rainy days, the general we have to set aside 3 to 5 days of rainy days, so lights Generally will be more normal. Solar street lamp life is related to the initial system configuration, do not blindly save costs, configuration is too low. At the same time,related to solar controllers, solar panels, batteries, LED light source of the quality, try to choose the regulate manufacturers products.
