Solar LED Street Light Principle Of Volt Effect

Solar LED street light Solar power lamps utilize solar cell's photovoltaic effect principle, solar cells absorb solar energy in the daytime to generate electricity, stored in the battery through the controller, when night falls or light illumination around the lamp lower, the battery through the controller to power source set time after cutting off.

Solar street lamps mainly consist of the following parts: Solar module, component bracket, solar Controller, accumulator, light source, lamp pole (incl. lamp) etc.

Solar panels are the core of solar street Solar LED street light lamps and the most valuable part of Solar street lamps. The function is to convert the solar radiation capability into electricity, or to be stored in a battery.

In many sunlight batteries are more common and more practical with monocrystalline silicon solar cells, polysilicon solar cell and amorphous silicon solar cell three kinds. In the sunny and sunny East West region, the use of polysilicon solar cells for good, because polysilicon solar cell production process is relatively simple, the price is lower than the single crystal. In rainy Solar LED street light days more, the sunlight is relatively not very abundant southern region, the use of monocrystalline silicon solar cells for good, because monocrystalline silicon solar cell performance parameters are relatively stable. Amorphous silicon solar cells are better in the case of outdoor sunlight, because amorphous silicon solar cells require less solar illumination

The whole solar cell Solar LED street light is encapsulated in the optimum EVA transparent plastic film between the surface glass and multilayer consumable polymer backplane. Aluminium frames with anodic oxidation are used around assemblies to protect assemblies and increase strength.

Polysilicon PV Module Quality Process Excellence, fully compliant with international standards IEC61215 testing requirements and through certification. Solar modules can withstand harsh weather conditions, including dramatic variations in temperature, humidity, strong winds and hail impacts.

Regardless of the size of solar lamps, a good charging discharge controller is essential. In order to prolong the life of the battery, it must restrict the charging discharge condition to prevent the battery charging and the depth charging. In the place where the temperature difference is larger, the qualified controller should also have the function of temperature compensation. At the same time, the solar controller should have the function of street lamp control, with light control, time control function, and should have the function of automatic control load at night, so that it can prolong the working time of street lamps.

This controller is specially designed for solar power supply DC street lamp, light control start-up + timing delay closure. Timing closure can be adjusted; with short circuit, overload, unique anti-protection and full-function protection measures such as automatic shutdown, charging instructions, faults and excessive discharge instructions.

As the input energy of solar photovoltaic system is extremely unstable, it is generally necessary to configure the battery system to work. Usually lead-acid batteries, Ni-Cd batteries, Ni-H batteries.

The selection of storage battery capacity generally follows the following principles: firstly, in the premise of satisfying night illumination, the energy of solar cell module is stored as much as possible, and the power to satisfy the need for continuous rainy day night illumination is also stored. Battery capacity is too small to meet the needs of night lighting, batteries too large, on the one hand the battery is always in the state of loss, affect battery life, at the same time cause waste.

Batteries should be matched with solar cells and electric loads (streetlights). You can use a simple method to determine the relationship between them. Solar cell power must be more than 4 times times higher than the load power, the system can work properly. Solar cells to exceed the voltage of the battery operating 20, to ensure that the battery normal negative. The battery capacity must be 6 times times higher than the load daily consumption.

Recycled solar batteries. Using ABS shell; safety valve: The use of acid-resistant heat resistance performance of EPDM made of excellent rubber, ensure the safety and reliability of the battery during use; The grille adopts the good corrosion resistance of PB-CA-sn-based alloy; clapboard: The use of acid-resistant heat-resisting properties of ultra-fine glass fiber made, to prevent the positive and negative short circuit, to maintain the electrolyte, pressing the plate surface, prevent the active material from
