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.

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.
