UP: Embodying change
Solar technology varies and solar manufacturing occurs in various parts of the world but the predominant technology relies on silicon solar cells, with a significant portion of manufacturing taking place in China. This leads to higher embodied carbon due to the production of silicon solar cells and the location of manufacturing, which often relies on an energy mix with more coal than renewables-based generation. At the scale of PV production in mid-2023, and beyond, the industry’s carbon footprint is significant, despite the generation of green energy by panels after their production.

Install grid-connected solar, rinse, repeat
Will a redeployable solar and energy storage solution be the answer to unreliable grid electricity across much of Africa, as its developer proposes? Or will it merely be a temporary solution that will see cash-strapped utilities kick the can of universal energy access further down the road? Max Hall investigates.

Supply tightens as n-type expands
The market share of high-efficiency, negatively-doped, “n-type” solar products, primarily tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) panels, will reach 25% to 30% this year, compared to just 7% in 2022. By 2024, n-type technology will surpass paasivated emitter rear contact (PERC) to become the next-generation mainstream cell tech. InfoLink has found multiple niches along the supply chain that are affected by this switch in technologies, including the supply of high-density wire mesh used in the screen-printing process.

UP: Trina goes for satellite production as solar scales
China still dominates the solar world in terms of PV market size and production output but the future will be more about distributed production, said Helena Li, president of Trina Solar’s global solar product business. With vertically-integrated production well established in Southeast Asia, and a new module fab announced in the United States, Li says that the company is now embracing a satellite production model.

Capital constraints
The Invesco Solar exchange-traded fund (ETF) TAN under-performed relative to the S&P 500 and the Dow Jones Industrial Average (DJIA) in August. Roth Capital Partners’ Jesse Pichel attributes this to pessimism around United States residential PV and rising interest rates, which are restricting access to capital for some.

Rocky road for critical minerals
Energy security has remained a burning issue in Europe since Russia’s invasion of Ukraine. While some analysts fear that plans to scale back coal-fired and nuclear generation capacity will weaken the European economy, others believe that the energy transition is a chance to redesign energy rules, technology, and values.

South African agrivoltaics lack spark
The farming sector in South Africa depends on Eskom to power irrigation and other operations but the state-owned utility is not delivering. This year, the country has faced daily blackouts of up to 10 hours or more. For farmers, securing reliable energy is a higher priority than experimenting with agrivoltaics.
