in China such as road, tunnel, square outdoor solar lighting technology has a good base for research and development capabilities and product development, and has a certain scale of production, application in lighting engineering has been a breakthrough, but the overall technology of solar lighting lamps and lanterns is not fully mature, the challenge is still very grim.

　　1. Solar lighting products price needs to be improved. In the cost of solar street lamps, solar lighting accounts for more than 50% to the total cost of the lamps and lanterns, and at present the imported light even though prices have fallen sharply, but the total cost on the high side, such as the 120 w solar street lamps need about 3000 yuan, and be replaced 250 w high pressure sodium lamp is about 1000 yuan, this is an important factor of restricting the solar lights accumulates promotion.

domestic solar street lamps manufacturer of high-end products imported chips, mostly from the national electric light source quality supervision and inspection center offers test results, the current solar street light, solar tunnel light the whole lighting effect of imported chips, generally can reach more than 90 lm/W, and use of the lamps in the domestic chip is 75 ~ 80 lm/W, only there are large gaps when compared with the two.

solar lighting products related to semiconductor application, optical, electronic, mechanical structure, the thermal aspects of subject, need good supporting ability, but many enterprises in the cooling technology, with optical technology, the structure design of lamps and lanterns does not have advantage, and led to the luminous efficiency of lamps and lanterns and light utilization coefficient, low efficiency of lamps and lanterns, fast attenuation in the practical use of lamps and lanterns, allows users to lose trust on the application of the solar lighting, hindered the widely application of solar lighting. Especially the drive power supply directly affects the reliability of the solar energy lamps and lanterns of the whole lamp life. Road lighting products used in the damage of solar lamps and lanterns, great majority is damage caused by the drive power supply.

　　2. Lack of standard solar lighting products. Because of the lack of product standards, solar street lamps products on the market the good and bad are intermingled, good and evil people mixed up, & other; Good product on the market at present probably account for only about 30% & throughout; The personage inside course of study says. Local government on solar street light project serious blind investment, low level repeated construction, combined with the tender method is undeserved, low-price bid, cause the malignant competition between manufacturers, make good products, jeopardizing the interests of enterprises and the user units.

　　3. Business model has not yet been established. Due to the solar street light die erste installation cost is high, and energy saving effect to be favorred by the parties, so the EMC model arises at the historic moment. But in practice there are problems, the model to run involves many departments, is very complicated, although talk more, but there are also companies, & other; Project will have been in the past two years, but the enterprise of recycling has not been to. ” Capital payback period is too long to the enterprise pressure is too large, in addition, electricity standard is not unified, around the base of power saving is difficult to determine, coordination mechanism complex become obstacle of EMC mode operation.
