in the first place, we must first understand the working principle of solar photovoltaic power generation, photovoltaic effect is through the solar panels convert light energy into electrical energy, which is the theoretical basis of photovoltaic power generation system. It includes photovoltaic panels, solar controller, battery and load. Photovoltaic panels is a core part of solar power generation system, is also the most important part of the solar system. It can absorb the solar energy into electrical energy, and turn it into the battery storage or promote work load. Solar street lamps [ ·。 jschindo。 com] Controller is used in solar power generation system of an automatic control device, is used to control the multi-channel solar arrays for battery charging, the battery to the load power of solar inverters. When supply power to the load current from the battery have also been allowed into the solar controller first, then the current is adjusted is sent to the load. The aim is to stable discharge current. The second is to ensure that the battery will not discharge. Third, the load and the battery can be a series of monitoring and protection. Battery to power the movement of drivers and pillar, and able to be in power or equipment are in a state of movement regulating equipment. Battery connected to the equipment control devices, if necessary, removable, so that quick charge. Light emitting diode lamp can display the battery state. Even when the power level is low, the pilot can also be performed before its battery runs out reciprocating motion, in order to ensure the safety of the equipment. Light-emitting diodes (leds) based on PN became the core of semiconductor light-emitting diodes. It is usually made of semiconductor materials, such as three compounds. When the ends of the power supply is connected to the PN junction, which produces an electric field p-n junction. Excess positive charge, or an empty hole, carried by P area, excessive negative charges, or electrons, carried by N. 。 Under the influence of positive voltage, electrons from n area invaded the p area, hole empty from p area invasion to n area. When p cavity empty in the area move to n area, and the electron in the n area moves to p area, will be in two areas at the junction of energy. The release of the energy from photons, photons produced by the energy released from the minority carrier and the combination of majority carrier. In recent years, the light-emitting diode applications has been developing rapidly in all walks of life. Light emitting diode drive circuit has become a key factor in the application. Theoretically, light-emitting diodes (leds) the service life of more than 100000 hours, but in the process of practical application, due to improper driving circuit design and drive mode selection, leds are easily damaged. Solar photovoltaic and led street lamp lighting system of high efficiency and energy saving solar photovoltaic power generation led lighting systems, including solar battery, DC - DC converter, high power tracking MPPT maximum power point tracking controller, batteries to store electrical energy, led lighting controller, led light source parts, etc.
