Finlay Colville, head of market research at Solar Media, said module prices will remain high for at least the next 18 months, additional capacity will be quickly eaten up by soaring demand, and adding capacity outside China is seen as risky. Speaking at the Solar Finance and Investment Europe (SFIE) conference in London, hosted by PV Tech publisher Solar Media in London, Colville said that over th...
On March 28, Eastern Time, the U.S. Department of Commerce said it would launch an investigation that may lead to anti-circumvention investigations into solar products imported from Malaysia, Thailand, Vietnam and Cambodia. The specific timetable is: 1) Beginning on March 28, US time, the US Department of Commerce began to conduct an anti-circumvention investigation on solar products imported from...
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...
As the "heart" of photovoltaic power generation, the health of the inverter is closely related to the smooth operation of the photovoltaic power generation system. It is necessary to understand common inverter alarms and accurately determine the cause of inverter alarms. 1. Inverter alarms not caused by internal devices If the screen or APP shows that the EEPROM fails, it can usually be repaired b...
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...
To ask "What is the most feared problem of photovoltaic power generation?" Experienced people must know "the problem of shadow occlusion." 1. Small shadows, big hazards Because the position of the sun changes with the seasons and time, and the surrounding potential obstructions also change over time, anyone with experience in installing photovoltaic power plants understands that shadows are ...
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...
