But also for the final debugging,if there are problems,causinggreat consumption.Cost comparisonSolar street lamp an investment,long-term benefit,because the line is simple,does not produce maintenance costs,does not produceexpensive electricity.6-7 years to recover the cost,after 3-4 years to save about1000000 of the electricity and maintenance costs.High city lamp circuit electricity,circuit complexity,need long-term and continuous on line maintenance.Special voltageinstability,the sodium lamp easily broken is inevitable,and with the extension oflife,the aging line,maintenance cost is increasing year by year.Safety comparisonSolarstreet lamp because the 12-24V low voltage,voltage stability,reliable operation,there is no security risk is ecological areas,highways department ideal product.Citycircuit lamp security risks,people's living environment in the ever-changingcircumstances,road reconstruction,landscape engineering construction,power supply isnot normal,water gas pipeline construction and other aspects of the many problems.Environmental protection contrastSolar street lamp can add new selling point for thedevelopment and promotion of ecological noble residential;sustainable lower propertymanagement costs,reduce the cost sharing common parts of summary thecomparison,solar lighting safety hidden danger,no energy consumption,greenenvironmental protection,simple installation,maintenance and other inherentcharacteristics of automatic control will sales of real estate,municipal engineeringconstruction directly clearly available advantage.Life contrastSolar energy lamp lifethan the life of the ordinary electric lamps and lanterns is much higher,the main partssuch as solar lamps,solar battery component service life of 25 years;low pressuresodium lamp,the average life expectancy of 18000 hours;6000 hours average lifeexpectancy of high and low voltage three primary colors of energy-saving lamp,led superbright,the average life expectancy of more than 50000 hours;solar energy battery lifefor 38AH following 2-5 years;38-150AH 3-7 years.According to the conventional cell inaccordance with local price bureau"according to provisions of the purely residentialconstruction area of a one-time charge of residential lighting maintenance costs 6 yuan/square meters",the The initial investment of ordinary lamps and lanterns should behigher than the initial investment of solar energy short,the characteristicsof saving investment in solar energy lamps are quite obvious.
