Solar street lamps of the early large investment is not big

Solar LED lighting at the beginning of the investment is still one of our main problem. Solar cells, however, photosynthetic efficiency is gradually improved, but the price will reduce gradually, the same cities LED lights in rapidly improve, but the price was lower. With solar

initial investment problem of solar LED lighting is still one of our main problem. Solar cells, however, photosynthetic efficiency is gradually improved, but the price will reduce gradually, the same cities LED lights in rapidly improve, but the price was lower. And renewable, clean pollution-free solar and LED the environmental protection and energy saving, compared to conventional fossil energy increasingly nervous, LED street lamps, and after use will cause the increasingly serious pollution to the environment.
