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...
What is a DC arc? Arc is a kind of gas discharge phenomenon, the instantaneous spark generated by the current passing through some insulating medium, such as air, this is the arc. Both direct current and alternating current produce arcs. Sometimes when we plug in the socket, we will see a fire, which is a kind of AC arc. In a DC system, such as that caused by a string of photovoltaic cells, this a...
The dust falling on the surface of the photovoltaic module will block the sunlight on the one hand, reduce the transmittance of the surface glass of the photovoltaic module, and reduce the amount of solar radiation irradiated on the surface of the solar panel; It absorbs solar radiation and converts it into its own heat energy, and at the same time blocks the external heat dissipation of the photo...
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...
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...
First of all, the basis of the working principle of solar cells is the photovoltaic effect of the semiconductor PN junction. The so-called photovoltaic effect is an effect in which electromotive force and current are generated when the object is illuminated, the state of charge distribution in the object changes. When sunlight or other light hits the PN junction of the semiconductor, a voltage app...
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...
