In addition, some garden outdoor lights appropriate use of glass products, some people think that glass is also one of the unstable factors in the safety of outdoor lights, but experts believe that good quality glass (especially special glass) even if the damage to people is small, if the developer can pay attention to the use of building materials, willing to cost good materials, you can greatly improve the safety factor.

There are three kinds of solar panels on the market for solar lighting: monocrystalline silicon solar panels, polycrystalline silicon solar panels and amorphous silicon solar panels. The conversion rate of monocrystalline silicon panels is higher, between 15-21%, followed by polycrystalline silicon panels, which can reach 16%, and the cost is also lower than that of monocrystalline silicon panels, so it is used by most lighting manufacturers.
