Asia takes the lead on floating PV

Floating PV is consolidating as a growth segment for PV demand, mainly driven by supportive policies and incentives extended by governments across the world. A major reason for this push is the limited land availability in many markets. Despite higher equipment prices compared to ground-mounted installations, developers see the opportunity to save on land and O&M costs. The output can also be as much as 30% higher than a ground-mount PV plant, depending on the site and technology used.

Copper is the new silver lining

As the PV industry scales to annual terawatt-level production to rapidly curtail the world’s emissions, it will become more challenging to continue the cost reduction trajectory. Increasing module production from current levels of 200 GW to 300 GW to several terawatts each year will consume significantly more material resources than the industry currently uses. This will require consideration of the additional materials to be sourced, writes Alison Lennon, chief scientist at Sundrive Solar and professor at the UNSW’s School of Photovoltaic and Renewable Energy Engineering.
