Impact of solar module soiling on grid-forming inverters
New research from Serbia claims air-polluted urban climatic conditions may not only induce maximum power point (MPP) tracking problems in PV systems but also reduce power yield by up to 30%. The scientists also said that soiling may significantly affect the functionality of single-stage inverters operating in grid-forming mode.
Solinteg unveils new inverter series for rooftop PV
Solinteg is offering nine versions of its new on-grid inverters, with nominal power ranging from 4 kW to 25 kW, an efficiency rating of up to 98.8%, and a European efficiency of up to 98.2%
Chinese PV Industry Brief: Huasun secures 2 GW PV order
Huasun has secured an order for 2 GW of solar panels from Power China, while Deye said it is seeking to raise CNY3.5 billion to expand its inverter production capacity.
German regulator warns of defective inverters in balcony PV systems
The German Federal Network Agency (Bundesnetzagentur) has identified issues with certain inverters that lack CE markings, instructions in German, or German retailer addresses. The defects render them ineligible for distribution or use in the country.
