the enormous strength of the solar energy application and prospects have been recognized and accepted by more and more people. As one of the solar energy application series products, solar lamps and lanterns has entered the stage of practical promotion. The solar energy lighting products in order to make people have a more adequate knowledge and understanding, now the solar garden light make the following comparison analysis with normal garden light. Example: a square construction, the need to install 10 w garden light, only 40 two lamp spacing of 40 meters, price 1000 yuan/only ordinary lamp, solar lamp price 4000 yuan/only, LED street lamp, contrast analysis:
