Solar energy is a source of light to the half-space, while the traditional high-pressure sodium lamp and metal halide lamp and other light sources are to the whole space. From the reflector on the light exit surface of the envelope angle to compare the traditional light source to send a large part of the light to be reflected or refracted through the optical system to exit, the optical system of light efficiency determines the overall efficiency of the lamp, and the traditional light source Its larger size, due to absorption, reflecting the secondary light and reduce lamp efficiency. solar powered portable generator has the characteristics of light to the board space, making the light source to absorb the proportion of light greatly reduced, which is the efficiency of solar lamps in the lamp one of the advantages.
Solar panels to reduce the heat island effect of the efficiency and service life of solar panels in order to maintain the efficiency and service life of solar panels, we must prevent the heat island effect of solar panels, and understand the solar island heat island effect There are external reasons there are internal reasons, the general external cause is the main reason for solar island heat island effect, in the production of solar panels to consider and solve the heat generated within the island effect.
If the solar cell module by other objects, such as bird droppings, shade and other objects long-term obscuring the surface of the solar panels, the block of solar cell modules will be serious heat, this time the heat island effect. This effect on the solar cell will cause very serious damage. A portion of the energy or all of the energy produced by the illuminated solar cell may be consumed by the shadowed solar cell. In order to prevent the solar cell from being damaged due to the heat island effect, it is necessary to connect a bypass diode in parallel between the positive and negative electrodes of the solar cell module in order to avoid the consumption of the energy generated by the irradiated solar cell module from being shielded by the solar cell module. Its role is in the component open or shade, to provide current path, and will not make the entire string of solar power batteries cell module failure.
Solar street light is closely related to people's production and life. As most of urbanization in China starts to accelerate, solar street light manufacturers use directional lighting, low power consumption, good driving characteristics, high response speed, high seismic capacity, long service life, and green Environmental protection and other advantages gradually into the people's vision, has now become the world's most alternative to the advantages of traditional sources of light a new generation of energy-saving light source, solar street lighting will become the best choice for energy-saving lighting.
