A grid-connected solar system is a system that connects a solar power generation system to the grid. It converts solar energy into electrical energy through a solar power generation system, and injects the generated electrical energy into the grid to supply power to users.The main components of grid-connected solar energy systems include solar photovoltaic cell modules, inverters, grid connection devices, and electricity meters. The solar photovoltaic cell module converts sunlight into DC power, converts the DC power into AC power through an inverter, and then connects the AC power to the grid and operates synchronously with the grid. At the same time, the system is also equipped with a grid connection device to ensure that the system can be stably connected to the grid, and monitor the energy generated by the solar system and the power injected into the grid through the meter.The operating principle of the grid-connected solar system is: when the solar photovoltaic cell components are irradiated by sunlight, electricity will be generated. The inverter converts direct current to alternating current and adjusts the output voltage and frequency to match the grid. The alternating current converted by the inverter can meet the electric energy demand of the user, and inject excess electric energy into the grid. When solar energy is insufficient or unable to meet user needs, the system will obtain the required power from the grid.The advantage of the grid-connected solar energy system is that it is convenient and reliable. Users do not need additional energy storage equipment, and can make full use of solar energy to inject electric energy into the grid, reducing energy waste. Obtaining electric energy from the grid ensures a stable supply of electric power. In addition, through the operation of grid-connected solar energy systems, carbon emissions can also be reduced, which is of positive significance to environmental protection.Renewable Energy: Solar energy is a renewable energy source that provides a sustainable supply of electricity from abundant solar resources.Green and environmental protection: solar power generation will not produce greenhouse gases and pollutants such as carbon dioxide, and has almost no negative impact on the environment, which is conducive to reducing global climate change.Save energy costs: Using solar power can reduce dependence on traditional power sources and reduce energy costs, especially in long-term operation can achieve significant savings.High Reliability: Grid-connected solar systems are generally highly reliable, as their components have a long life and are less prone to damage, allowing them to continue operating under changing weather conditions.Reduce grid pressure: Solar grid-connected systems inject electricity into the grid, which can reduce the demand for traditional power sources and effectively relieve grid pressure.Grid-side energy compensation: If the solar grid-connected system generates more electricity than it needs, the excess electricity can be sold to the grid to enjoy electricity fee compensation or income.Flexibility and scalability: The solar grid-connected system can be flexibly configured according to needs, and can be expanded by adding components such as solar power generation devices and inverters.1: Q:What's the different between inverter and solar inverter?A: Inverter is only accept AC input, but solar inverter not only accept AC input but also can connect with solar panel to accept PV input, it more save power.2.Q:What are the advantages of your company?A:Strong R & D team, independent R & D and production of main parts, to control product quality from the source.3.Q:What kind of certificates your products have acquired ?A:Most of our products have acquired CE, FCC, UL and PSE certificates, which is able to satisfy most country’s importing requirements.5.Q:How do you ship the goods since they are high capacity battery ?A:We have long-term cooperated forwarders who are professional at battery shipment.1, User solar power supply: (1) Small power sources ranging from 10-100W are used for military and civilian daily electricity in remote areas without electricity, such as plateaus, islands, pastoral areas, border checkpoints, etc., such as lighting, televisions, radio recorders, etc; (2) 3-5 KW household roof grid connected power generation system; (3) Photovoltaic water pump: used for drinking and irrigation in deep water wells in areas without electricity.2, In the field of transportation, such as beacon lights, traffic/railway signal lights, traffic warning/marker lights, Yuxiang street lights, high-altitude obstacle lights, expressway/railway wireless Telephone booth, unattended road crew power supply, etc.3,Communication/communication field: solar unmanned microwave relay stations, optical cable maintenance stations, broadcasting/communication/paging power supply systems; Rural carrier telephone photovoltaic system, small communication equipment, soldier GPS power supply, etc.4, In the fields of oil, ocean, and meteorology: cathodic protection solar power supply system for oil pipelines and reservoir gates, living and emergency power supply for oil drilling platforms, ocean detection equipment, meteorological/hydrological observation equipment, etc.5, Home lamp power supply: such as garden lamp, street lamp, portable lamp, camping lamp, mountaineering lamp, fishing lamp, Blacklight, rubber cutting lamp, energy-saving lamp, etc.6, Photovoltaic power plants: 10KW-50MW independent photovoltaic power plants, wind (diesel) complementary power plants, various large parking and charging stations, etc.7, Solar buildings combine solar power generation with building materials to achieve self-sufficiency in electricity for future large-scale buildings, which is a major development direction in the future.8, Other fields include: (1) supporting vehicles: solar cars/electric vehicles, battery charging equipment, automobile air conditioners, ventilators, cold drink boxes, etc; (2) Renewable power generation system for solar hydrogen production and fuel cells; (3) Power supply for seawater desalination equipment; (4) Satellites, spacecraft, space solar power plants, etc.Factors to consider in the design of solar power generation systems:1.
