Solar energy as a kind of important new energy, with renewable, wide distribution, no pollution, large reserves to replace the traditional advantages of conventional energy sources. As for solar energy utilization technology matures, the cost of solar power technology has been reduced, solar power generation technology is becoming more and more widely applied to various fields, the solar garden light now is such a mature technology, the development of getting better and better. At present, the development of the solar garden light advantage is to improve the conversion efficiency of solar energy, reduce the volume of panels, provide more power; For solar garden light controller is improved, the charging current pulse current, and thus reduce the polarization of battery, improve the charging efficiency; To improve the service life of the battery, reduce traditional battery pollution to the environment; Using LED light source to improve the intensity of illumination and brightness. Both from the panels of solar garden light conversion rate increase, the improvement of controller, and battery life, the extension of the illumination efficiency of lamps and lanterns, we all can see the operation value of solar garden light the whole lighting, but is more and more good reason for the development of a solar garden light.
