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.
