Market opportunities present, China has become the world's largest producer of photovoltaic solar cells, and emerged as the representative of Suntech photovoltaic manufacturers a number of international competitiveness and international reputation, the formation of a large-scale, international, professional of the industrial chain. But PV join because of the high cost of power generation, photoelectric conversion rate, optical and network, people's awareness of the many reasons for low PV Join the current lack of domestic market demand, to a certain extent, affected the industry. The sharp contraction in short-term external needs of photovoltaic agency cooperation, external dependence is so high as 70% -90% of the photovoltaic industry in a recession. The introduction of the policy, such as Sudden Impact make the photovoltaic industry see hope. Solar street lighting system, solar street lighting system components can protect more than 15 days of rainy weather to work! Its system components are made (including the stand), LED lamp, solar lighting controllers, batteries (including a battery incubator) and poles of several parts. Monocrystalline silicon solar cell module is generally used or polycrystalline silicon solar cell module; LED lamp is generally used in high-power LED light source; and a controller is generally placed in the pole, with light control, time control, overcharge and over discharge protection and reverse polarity protection, more advanced controllers more time with the seasons adjust lighting function, half-power, intelligent charge and discharge functions; batteries are generally placed on the ground or the battery will have a special incubator, can be VRLA batteries, gel batteries, almandine batteries or lithium batteries. Solar lighting automatic, requiring no trenching wiring, but the poles need device embedded parts (concrete base) on.
