　　1. Solar panels

solar panels for solar street lamp power supply components. Its function is to convert solar energy into electricity and transferring them to the battery. It is the most valuable part of solar street lamps. Monocrystalline silicon solar cell is the main material. Sunshine and radiant heat will promote and affect P - in a solar cell N junction of holes and electronic movement. It is also known as the photovoltaic effect principle. At present, about 13% of the single crystal silicon photovoltaic conversion power - 11% - 15%, the polysilicon 13%. The latest technology including photovoltaic thin-film batteries.

　　2. Battery

the battery is the energy storage solar street light. Collection of power supply to the street lamp to complete illumination. As the input energy solar photovoltaic power generation system is very unstable, often need to configure the battery system to work. Usually have lead-acid batteries, nickel cadmium battery and nickel metal hydride batteries. Choice of battery capacity is usually follow the following criteria: first of all, on the premise of meet the night lighting, should be as much as possible to store the energy of the solar cell components, and can meet the demand of light energy. Continuous rainy day and night. Battery capacity is too small, unable to meet the needs of night lighting. The battery is too big. On the one hand, the LED street lamp, battery power shortage status has been in the radiator, it will affect the life of the battery and together form a waste. Battery should be with solar cells and electrical load ( Street lamp) Match. There is a simple method to confirm the connection between them. The solar cell power must be more than four times higher than the load power and this system can run normally. Solar battery voltage should be more than 20 - the working voltage of the battery Negative 30%, ensure the normal battery. Battery capacity should be more than 6 times higher than the daily load consumption.

　　3. Control inverter

solar controller performance directly affect the service life of the system, especially the battery life. Controller using MCU industry as the main controller. By measuring the ambient temperature, detection and judgment and battery voltage and current of the solar cell module parameters, can control the MOSFET device switch, realize all sorts of control and maintenance functions.

　　4. LED light source

choose solar street lamps light source is an important index of normal operation of solar lamp. Usually, low voltage energy-saving lamps, low voltage sodium lamp, energy-saving lamps, LED light source used for solar light, some of which are high power LED light source.

　　5. Light pole lamp holder

light pole LED street lamp installation support.
