Solar modules, fans, solar high-power LEDs, LPS lamps and lanterns, photovoltaic control systems, fan control systems, solar special maintenance-free batteries and other components, solar module brackets, fan accessories, light poles, pre-buried parts, battery buried boxes, and other accessories. Next in detail.
1、Wind turbine
A wind turbine is a facility that converts natural wind into electricity and sends the electricity to the battery for storage, which provides energy for the street light together with the solar panel. Depending on the power of the light source, the power of the wind turbine used is also different, generally 200W, 300W, 400W, 600W, and so on. There are also several kinds of output voltage such as 12V, 24V, 36V, etc.
2、Solar panel
The solar panel is the core part of the solar street light and the highest value part of the solar street light. Its role is to convert the sun's radiation power into electricity or send it to the battery for storage. Among the many solar cells, the more common and practical are monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells. In the east and west of the region where sunlight is abundant and good, polycrystalline solar cells are used because the production process of polycrystalline solar cells is relatively simple and the price is lower than monocrystalline. In the southern region where there are more rainy days and the sunlight is not very sufficient, it is better to use monocrystalline solar cells because the performance parameters of monocrystalline solar cells are more stable. Amorphous silicon solar cells are better in the case of insufficient outdoor sunlight because amorphous silicon solar cells have lower requirements for sunlight conditions.
3, solar controller
Regardless of the size of solar lamps and lanterns, good performance of the charge and discharge controller is essential. In order to extend the service life of the battery, it must be charged and discharged to limit the conditions, to prevent the battery from overcharging and deep charging. In places with large temperature differences, qualified controllers should also have a temperature compensation function. At the same time, the solar controller should also have the street light control function, with light control, time control function, and should have automatic cut control load at night, to facilitate the rain and cloudy days to extend the working time of street lights.
4、Battery
As the input energy of the solar photovoltaic power generation system is extremely unstable, so generally need to configure the battery system to work. There are generally lead-acid batteries, lithium-ion batteries, li-ion, Ni-Cd batteries.
5、Light source
Solar street lights using what light source is an important indicator of whether the solar lamps and lanterns can be used normally, the general solar lamps and lanterns using low-voltage energy-saving lamps, low-voltage lamps, induction lamps, LED light sources.
6、Lighting pole and lamp housing
The height of the pole should be determined according to the width of the road, the spacing of lamps and lanterns, and the illumination standard of the road. According to my tungsten collected many foreign solar lamp information, between the beautiful shell and energy-saving, most of them choose energy saving, the appearance of the lamps do not require high, relatively practical on the line
