The price of the light pole1
As the traditional energy increasingly scarce, the application of solar energy will be more and more widely, especially solar power areas in a short span of few years has developed into a mature sunrise industry. 1: currently, restrict the application of solar power price is one of important link,
along with the increasing shortage of traditional energy sources, the application of solar energy will be more and more widely, especially solar power areas in a short span of few years has developed into a mature sunrise industry.
1: currently, restrict the application of solar power * price is one of important link, with a light dual solar street light, for example, two road load sharing is 60 watt, 4 effective light in the middle and lower reaches of the Yangtze river region. 5 h/day, 7 hours each night discharge, calculate the panels to 20% increase in reserve) The panels will need to about 160 w, calculated at $4 per watt, the cost of the panels will be 640 yuan, plus 180 ah battery costs are at around 1080, the whole street lamp one-time investment cost is much higher than the utility street lamp, caused a major bottleneck in the field of solar street light applications.
2: the service life of the battery should also be considered in the whole street lamp system application, usually the battery warranty of three years or five years, but the general battery in one year or even half a year later will be in charge of discontent, some actual charge rate may fall to about 50%, it will affect the normal continuous rainy period of night lighting, so choose a good battery is especially important.
3: some project traders often choose LED lights as a solar energy street lamp lighting, leds are of variable quality, however, serious LED light failure could light attenuation 50% half a year. So be sure to choose the droop slower LED lights, or choose electrodeless lamp, low voltage sodium lamp, etc.
4: the choice of the controller is often overlooked by engineering contractor of a problem, the quality of the controller layer is poor not neat, 12 v / 10 a controller market prices ranging from 100 yuan to 200 yuan, although it is value * a small part of the whole street lamp system, but it is a very important link. Controller is good or bad will directly affect the life of components of solar street light system and the purchase cost of the whole system, one: should choose low power consumption controller, the controller working 24 hours a day, as their power consumption is bigger, will be part of the electricity consumption, * choose power consumption in 1 ma ( MA) The following controller. 2: choose a controller of high charging efficiency and charging with MCT mode controller can automatically track panels * current, especially in winter or insufficient light, MCT charging mode efficiency is about 20% higher than the other. Three: should choose to have two way to adjust power controller, adjust the power controller has been widely promotion, deserted in the night time can be automatically shut down all the way or two way lighting, save electricity, can also LED lights for power regulation. In addition to select the saving function, but also should pay attention to the protection function of controller for battery and other components, as has a trickle charge mode controller can very good protection batteries, increase the service life of battery, the other set controller under-voltage protection value, as far as possible the under-voltage protection value adjusted in & ge; 11. 1 v to prevent the battery discharge.
5: far away from downtown should also pay attention to the security work, many engineering contractor for construction of negligence, not effectively guard against theft, lead to battery, panels and other components are stolen, not only affects the normal lighting, also creates unnecessary damage to property. Mostly in the engineering case stolen for the battery, and battery buried in concrete pouring is an effective security measures, on the light pole mounted battery box * its weld reinforcement.
6 waterproof of the controller, the controller is generally installed in the chimney, battery box, generally do not water, but in the actual engineering case controller terminal connections often because of the rain down the cable into the controller caused by short circuit. So in the construction should pay attention to the internal cable bent into & other; U” Type and fixed type, external connections can also be fixed for & other; U” Type, so that the rain can't pour into the controller caused by short circuit, it also can be applied waterproof glue, perimeter joints. 【 The above content released by solar street lamps factory finishing for you 】
