what are the defects solar street light? LED solar street light' LED solar street lights with solar radiation as energy, using solar panels to convert solar energy to the battery to charge during the day and night to use LED light source power supply lighting, battery without complex and expensive pipeline laid, can be arbitrary adjust the layout of the lamps and lanterns, safety and energy saving no pollution, no manual work is stable and reliable operation, saving electricity maintenance free. 】 In our daily life are mainly applied in the electric power facilities is inconvenient places, such as advertising companies often use it to make big outdoor lighting, and because it is through the sun to provide energy for lighting, so it is very environmental protection relative to electric lights, although it has 'limitless reserve, the use of' advantage, but it also has its own drawbacks, below is the advertising equipment procurement market sales personnel to introduce some disadvantages of LED solar street light, everyone together to get to know. The LED solar lamp faults mainly include the following: 1, the dispersion reached the amount of solar radiation on the surface of the earth although is very big, but can flow density 【 Energy flow density is within a certain space, per unit area ( Such as square meters) What can be achieved or unit weight ( Such as kg) Energy will have a certain energy energy or power. 】 Is very low. On average, the tropic of cancer' The tropic of cancer and the tropic of cancer, Tropic of Cancer originated from the English name of the Tropic of Cancer, more than two thousand years ago) , the sun is in the northern hemisphere can direct to the position of the farthest from the equator, is a parallel, which is around to plane and the earth by the earth around the sun into the Angle of the equatorial plane, also - beihuiguixian】 Nearby, 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. 2, instability due to the 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. 3, 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.
