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...

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...
