Outdoor solar garden light design requirements and component selection
As the light source for most roads and courtyard lighting applications, the outdoor solar garden light has realized good application in the courtyard lighting project. However, with the stringent requirements on the quality of outdoor solar garden lights, only a good design scheme and material selection criteria can achieve high-efficiency and energy-saving lighting.
First of all, should be based on national standard requirements for outdoor solar garden light design, this time is proposed to adopt 36 or 72 monocrystalline silicon solar cells in series to form 12V or 24V each model of the component design to meet the actual lighting requirements .
Second, the solar cell output power should be 3 to 5 times the power of the light source, ample light when the lights open area for more than 3 to 4 times, on the contrary for more than 4 to 5 times to ensure the stability of the system work; different time Different locations, the same piece of solar cell output power is different, so the outdoor solar garden light power design is based on sunny conditions around the sun before and after the reasonable configuration.
Outdoor solar garden lights commonly used in solar panels are mainly two kinds of monocrystalline silicon and polysilicon, the panel selection, the panel antireflection film should be enhanced plasma CVD of silicon nitride film, the unit area of the panel Output power of about 127Wp / m2, uniform conversion efficiency> 17%.
To ensure the normal charge of the battery The operating voltage of solar cells is about 1.5 times the battery voltage, the general need 12V battery charging with 15 ~ 18V solar cells, 24V battery charging needs 33 ~ 36V solar cells. http://www.titanwindturbine.com
