Solar street light manufacturers share the advantages of solar electromagnetic panels

Why are solar electromagnetic panels so popular today, what are the advantages? Next, the solar street light manufacturers will introduce you specifically.

Solar photovoltaic panel itself is a solar panel, photovoltaic panel is a professional term, solar panel is a general term for our solar power generation. Photovoltaic panels are a type of solar panels that use semiconductor materials to generate electrons from inside and holes to generate currents under light. Solar panels include several methods of photovoltaic power generation. The system is composed of solar battery, solar controller, and storage battery (group). If the output power is AC 220V or 110V , you need to configure the inverter. The role of each part is:

Solar panel: The solar panel is the core part of the solar power system and the most valuable part of the solar power system. Its role is to convert the sun's radiation capacity into electrical energy, or send it to the storage battery to store it, or promote the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system.

Solar controller: The role of the solar controller is to control the working status of the entire solar street light system, and play the role of overcharge protection and overdischarge protection for the battery. Where the temperature difference is large, a qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch and time control switch should be optional for the controller.

Storage battery: Generally it is lead-acid battery. In small and micro systems, nickel-metal hydride battery, nickel-cadmium battery or lithium battery can also be used. Its role is to store the electrical energy emitted by the solar panel when there is light, and then release it when needed.

Inverter: In many occasions, 220VAC and 110VAC AC power needs to be provided . Because the direct output of solar energy is generally 12VDC , 24VDC , 48VDC . In order to provide power to 220VAC appliances, it is necessary to convert the DC power generated by the solar power generation system into AC power, so it is necessary to use a DC-AC inverter. On some occasions, you need   When using a load of multiple voltages, a DC-DC inverter is also used , such as converting 24VDC power into 5VDC power (note that it is not a simple step-down).

Solar street lights have certain irrationality when they are turned on according to the light control point. In many cases, users need to turn on the lights when the sky is not completely dark and the light is not completely lower than the light control point. Conventional solar street lights do not To this point.
