photovoltaic power generation system is divided into independent photovoltaic power generation systems, photovoltaic grid photovoltaic power generation systems and distributed systems. 1. Independent photovoltaic power generation is also known as off-grid photovoltaic power generation. It mainly consists of solar modules, controllers and batteries. For communication load power supply, communication inverter is needed. Independent photovoltaic power station including rural village power supply system, solar household power supply system, signal power, cathodic protection, solar street lamps and other battery can run independently with photovoltaic power generation systems. 2. Grid photovoltaic power generation refers to the direct current (dc) solar cell components produced by grid inverter converted to meet the requirements of commercial power grid communication power supply, direct access to the public grid. It can be divided into with battery and without battery grid-connected power generation system. With battery is schedulable grid-connected power generation system, can according to need access to or withdraw from the power grid, and has backup power function. When the power was cut off for some reason, signal light pole manufacturers can emergency power supply. Photovoltaic (pv) grid power generation system with accumulator are normally installed in residential buildings. No battery grid-connected power generation system does not have the function that can scheduling sex and standby power supply, usually installed in a larger system. Large centralized grid photovoltaic grid photovoltaic power station is usually national power station. Its main characteristic is the energy transfer directly to the power grid, the grid unified supply power allocated to users. However, this power plant investment, long construction cycle, covers an area of big, and implementation. Scattered small-scale photovoltaic (pv) grid power generation, however, especially photovoltaic building integrated photovoltaic (pv) power generation, because of its small investment, quick construction, cover an area of an area small, the advantages of the policy support big, become the mainstream of photovoltaic (pv) grid power generation. 3. Distributed photovoltaic power generation system, also known as or distributed power, distributed generation refers to the user scene or near equipped with smaller units of photovoltaic power system, in order to meet the needs of specific users, support for economic operation of the existing distribution network, and can meet the requirements of both. Distributed photovoltaic power generation system of the basic equipment includes photovoltaic module, photovoltaic phalanx, DC female head, DC distribution cabinets, grid inverter, communications, power distribution cabinet and other equipment, and power supply system monitoring equipment, and environmental monitoring equipment. Its operation mode is in the case of solar radiation, photovoltaic power generation system of solar cell module array to convert solar energy into electrical energy output, through the DC bus after collection to DC power distribution cabinet, grid inverter reverse transformation for communication power supply to establish their own load, through the grid to adjust excess or deficiency of electricity.
