with throughout the growing shortage of energy, especially solar power range within the short several years long has become into broken life asahi industry forward, most of the application of solar street lights will be more and more. 1: now restrict the application of solar power is one of the most important part of the price, with a light dual solar street light, for example, the application range of the primary bottleneck solar street lamps, lights global one-time in cost and much higher than the mains street lamp, calculated on per watt 30 yuan, the cost of the panels will be 4800 yuan, plus 180 ah battery costs are at around 1800, ( Badly behaved in the Yangtze river region effective light days, 7 hours each night discharge, add panels 20% reserve amount calculation) The panels will demand about 160 w, two road load such as 60 watts. It will affect the normal start bleak day time at night lighting, so choose a good battery is especially important, but the common battery in one year or even half a year the other day will show the charging an uncomfortable situation, 2: the exercise of the battery life should also weigh in global street lamp system applications, the common battery warranty for three years or five years, some real charge rate is likely to fall to around 50%. Not neat, but the quality of the LED lights layer 3: some project traders often choose LED lights for solar street lighting, light failure, serious LED can light attenuation 50% six months. So the best choice for light, long life, high light efficiency, light decay slower LVD energy-saving lamps, does not necessarily choose low voltage sodium lamp, etc. , of course, is the value of the smallest part of the global system of street lamp, 12 v / 10 a in 100 - of minimizing the market price Poor quality of 200 yuan, minimizing layer not neat, 4: choice of minimizing is frequently overlooked by engineering contractor of a problem, but it is one of cockiness important link. Minimizing of good or bad will directly affect the solar street light system component life and overall system netting cost, will loss some electricity, had better choose power consumption in 1 ma ( MA) The following minimizing, minimizing 24 hours and pay the transaction, as its power consumption is larger, the LED street lamp, 1: should receive government degrees choose minimizing device with low power consumption. Especially in winter or not enough light era, with MCT charging model of minimizing maximum current can take the initiative to track panels, 2: choose charging high effectiveness of minimizing, the effectiveness of MCT charging mode than other beyond 20%. Pedestrians sparse in the night time it doesn't matter active moldy or two road lighting, park electricity, with power regulation of minimizing has been mostly, also it doesn't matter LVD lights for power regulation, three: should choose to have two way to adjust power minimizing. Should also pay attention to minimizing device ensure the efficacy of battery and other components, in addition to support minimizing, under-voltage guarantee value add to the life of the battery, as has a trickle charge mode of minimizing doesn't matter good battery, resist the battery discharge, in addition to select the power saving effect, as far as possible the under-voltage guarantee value in p.
