PV modules with longer lifetimes could slash demand for materials

The National Renewable Energy Laboratory (NREL) says in a new report that PV module lifetime extensions should be prioritized over closed-loop recycling to reduce demand for new materials.

Algae could boost solar panel efficiency by 4%

A Swedish team has inaugurated a pilot facility to mass produce algae material that can potentially boost silicon solar module efficiency by 4% and thin film by 36%. The algae are added to the encapsulant in silicon-based modules or to the anti-reflective coating on the glass of thin film modules. The team estimates the resulting modules would be 3.9% cheaper.

Cooling down solar modules by increasing space between panel rows

A U.S. research team claims to have demonstrated that increasing the spacing of solar panels between rows improves PV system efficiency and economics by allowing airflow to cool down the modules. The method could improve a project’s LCOE by as much as 2.15% in certain climates.

Global installed PV capacity could hit 260 GW in 2022

The International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS) estimates that 173.5 GW of new solar capacity was installed in 2021, and that figure might rise to 260 GW in 2022. pv magazine spoke with the co-chair of the European Solar Manufacturing Council to look into the figures.
