compared with conventional lighting, the advantages and disadvantages of solar energy lamp advantage ( Recommend reasons) 1, can be installed in the independent, LED street light, without digging ditches, buried lines, backfill, save construction costs; 2, without purchasing power capacity of equipment, save the expenses of the corresponding complete equipment; 3 can realize full automatic control, solar lamps and lanterns, no personnel management, save management costs; 4, to the sun for energy, do not use the conventional electric energy, save operating cost; 5, easy to maintain, will not get an electric shock accidents, the use of safe. Disadvantage ( Select concerns) 1, the comprehensive efficiency directly affected by the intensity of local sunshine, can't meet the demand of the installation of the sun area; 2, the solar cell components to accept the sun was shining and steer clear of obstructions, the specific installation location is limited; 3, without considering the construction, operation, maintenance and other fees under the premise of the initial investment cost of single lamp slightly higher; 4, such as solar modules installed on the light pole, need to consider the overall wind strength, investment will be slightly higher than the ordinary light pole.
