Modules & Upstream Manufacturing

Bill Nussey describes in his new book a much larger role that he foresees for local solar and storage, and a correspondingly altered role for electric utilities.

On the company’s Q4 earnings call, the world-leading EV manufacturer again prioritized delivering cars over growing low-margin energy storage products, while solar products were barely noted. Both verticals grew though, solar by 68% and storage by 32%.

A group of companies comprising Akuo Energy, Amarenco, BayWa re, EDF Renouvelables, Enel Green Power, Engie, Iberdrola and Vattenfall has sent a letter to the European Commission to ask for a strategy to build up a continental PV supply chain.

German scientists have developed a perovskite PV cell with remarkable stability by adding a bilayer of polymers that protects the perovskite from corrosion. This design helps to shield the extremely sensitive perovskite interface and provides the cell with extraordinarily high conductivity.

An international research team has investigated how solar could be combined with thermoelectric coolers (TECs), which are small solid-state heat pumps used either for heating or for cooling. A system was built with six solar panels, an air duct system, four batteries, a charge controller, TECs, an inverter, heat sinks, a test chamber, and condenser fans.

A preliminary ruling by the European Court of Justice states panel makers should not be responsible for electrical waste management costs in a seven-year period as the rules in place before the EU’s WEEE directive entered force, in 2012, permitted member states to place the obligation on panel users instead. The resulting change in law, in some states, cannot be applied retroactively, under EU legal rules.

Scientists in Australia have analyzed the state-of-the-art of all gettering technologies used in the solar industry. This technique, which is aimed at reducing defects in wafer manufacturing, may become more important in the future, as cell efficiencies increase and become increasingly sensitive to traces of metallic impurities.

Egyptian researchers have analyzed all cooling techniques for solar module cooling. Their review includes passive and active cooling methods, cooling with phase change materials (PCMs), and cooling with PCM and other additives, such as nanoparticles or porous metal.

SunWiz has identified the most popular solar panel and inverter brands in the Australian market. In total, 5.2 GW of solar was installed in Australia in 2021, putting the country’s cumulative tally at 26.9 GW.

According to PVInfolink, the top 10 solar manufacturers accounted for over 160GW of shipments or a global market share of 90% in 2021.
