  • 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: 1.energy-saving: solar energy to provide electricity conversion, inexhaustible; 2. environmental protection: no pollution, no noise, no radiation; 3.security: 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

    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...

  • ¿Cuánto tiempo puede usarse una farola solar en áreas rurales? 2017-12-16
    ¿Cuánto tiempo puede usarse una farola solar en áreas rurales?

    el estado para apoyar la nueva energía,\r\nmuchas partes del país están instaladas luces de calle solares, una calle solar\r\nLas luces se pueden usar por cuánto tiempo, esta es una gran cantidad de beneficiarios son los más\r\npreocupado por. vida y paneles solares, controlador solar, fuente de luz led, el\r\nbatería, a continuación tengo que analizar el impacto del uso de las luces de calle solares\r\nde estos factores: 1.the\r\nvida de paneles solares generalmente hasta 25 años, siempre y cuando usted sea un\r\npanel solar fuera del producto, la vida de los polos puede llegar a más de 30\r\naños, el uso de partes de una vida tan larga, no se puede considerar. 2.solar\r\nla tecnología del controlador de luz de calle ahora es más madura, no se rompe fácilmente,\r\nsiempre que el uso correcto de las instrucciones no cause mucha amenaza. incluso\r\nsi la falla, el precio es relativamente barato, muchos fabricantes son comunes,\r\nfácil pedido, el mantenimiento también es simple. 3.led\r\nfuente de luz y duración de la batería, duración de la batería, los fabricantes generalmente prometieron\r\nde 3 a 5 años, pero si la configuración general del sistema es demasiado pequeña, la\r\nlas luces de la calle siempre se usan en un estado de pérdida, por lo que la batería será\r\nmuy rápido, es decir, el impacto de la duración de la batería. algunos pueden tener de 2 a 3 años\r\ntiene que ser reemplazado una vez usualmente usamos la batería, es necesario tomar\r\ntener en cuenta la carga diaria de paneles solares, pero también considerar la potencia diaria\r\nconsumo de luz, días lluviosos, el general tenemos que dejar de lado de 3 a 5 días\r\nde días lluviosos, entonces las luces generalmente serán más normales. la duración de la lámpara solar de la calle está relacionada con la configuración inicial del sistema, no\r\nCiegamente ahorra costos, la configuración es muy baja. al mismo tiempo, relacionado con la energía solar\r\ncontroladores, paneles solares, baterías, fuente de luz led de la calidad, intente\r\nelija los productos del fabricante de regulación
