After being approved by the South Korean board of directors on February 22, LG Electronics announced that the company will withdraw from the global solar module manufacturing business. LG Electronics said increased material and logistics costs and severe supply constraints were the main reasons for the decision to halt solar module manufacturing. It is reported that LG's 550MW solar ...
Solar storage system, including solar modules, controllers, inverters, batteries, loads and other equipment. At present, there are many technical routes, but the energy needs to be collected at a certain point. At present, there are mainly two topologies of DC coupling "DC Coupling" and AC coupling "AC Coupling". 1, DC coupling As shown in the figure below, the DC power generated by the photovolta...
According to the latest annual clean energy statistics report released by the International Renewable Energy Agency (IRENA), the installed capacity of off-grid photovoltaic systems installed around the world has barely increased since the outbreak of theCOVID-19 in 2020. According to the report released by the agency, most of the countries that own and operate off-grid PV systems aroun...
In general, we call the process of converting DC power into AC power as inverter, the circuit that completes the inverter function is called inverter circuit, and the device that realizes the inverter process is called inverter equipment or inverter. Why are common grid-connected inverters only single-phase and three-phase? In fact, the main reason is the type of grid connected to the inverter. Fi...
With the gradual tightening of global energy supply and increasingly serious environmental pollution, independent and environment-friendly energy supply is becoming more and more important, and more and more households around the world choose to embrace this green energy transition with green electricity at home. However, in the face of the numerous and chaotic household energy storage products on...
The large number of solar panels installed in the early 2000s is approaching the end of its life cycle, which poses a serious problem for the solar industry, and current solar panel disposal methods fall far short of environmental requirements. In theory, solar energy is more promising than ever. Solar cells are getting easier and cheaper to produce. But solar PVs have some less-talked-about quest...
The German government continues to address the energy crisis by implementing tax relief to support small photovoltaics. This time, the tax relief is aimed at supporting PV systems under 30kW. The new rules plan to start in early 2023, and any photovoltaic system operating on a single-family residential or commercial property with an output of up to 30kW will no longer be required to pay income tax...
Energy storage converter, also known as bidirectional energy storage inverter, English name PCS (Power Conversion System), is used in AC-coupled energy storage systems such as grid-connected energy storage and micro-grid energy storage, connecting battery packs and power grids (or load), it is a device that realizes bidirectional conversion of electric energy. It can not only invert the DC power o...
The warranty of a solar system involves solar panels, inverters, installations and various other components. Owners always want to be effectively guaranteed throughout the life cycle of the solar system, and they know that it is important to choose the right solar panels and inverters. , it is also important to know that these components are properly installed. But when it comes to warranty, there...
Photovoltaic inverters are composed of circuit boards, fuses, power switch tubes, inductors, relays, capacitors, displays, fans, radiators, structural parts and other components. The service life of each component is different. The service life of the inverter can be explained by the "barrel theory". The maximum capacity of the barrel is determined by the shortest board, and the service life of th...
In recent years, with the continuous reduction of the cost of photovoltaic power generation, photovoltaic power generation has gradually become the main energy source in the new power system. Module products are the core power generation equipment of photovoltaic power stations, and their safety and reliability will directly affect the power station long-term stable operation. Ensuring the quality...
Recently, the power shortage in South Africa has intensified. In order to deal with the energy crisis, the South African government announced that it will encourage private enterprises to increase investment and promote the construction of renewable energy power generation projects while increasing electricity imports. It is understood that in the past few years, South Africa has experienced power...
