By 2035, The İnstalled Capacity Of Offshore Floating Solar Power Plants Will Exceed 25 GW.

What İs This Development?

Offshore floating solar power plants (floating PV) consist of photovoltaic panels mounted on platforms placed on the sea surface. According to YearlyFuture's estimate, their global installed capacity will exceed 25 GW by 2035.

Unlike land-based PV, offshore floating PV requires floating platforms resistant to wave, saltwater, and wind loads. As of 2024, total installed capacity in the Netherlands, Singapore, and Japan is below 100 MW. According to the S&S Insider 2025 report, the solar and battery storage market was USD 2.71 billion in 2025 and will reach USD 11.64 billion by 2035.

Why Does İt Matter?

Offshore floating PV eliminates land constraints and evaporation losses in freshwater floating PV. The Offshore Energy Storage Market report (2025) shows the offshore energy storage market will grow from USD 354 million in 2024 to USD 1,597 million by 2035, at 14.68% annually.

This growth is also linked to offshore wind capacity reaching 234 GW by 2030. Sharing the same marine area for wind and solar reduces grid connection costs. According to YearlyFuture data, by the end of 2031, offshore floating PV's share of total floating PV could reach 18%.

Frequently Asked Questions

What İs Offshore Floating PV?

It refers to power plants that generate electricity from solar panels on floating platforms installed on the sea surface. Unlike land-based PV, it uses systems resistant to saltwater, wave, and wind conditions.

How Much Offshore Floating PV Capacity Will There Be İn 2035?

According to YearlyFuture's estimate, global installed capacity will exceed 25 GW by the end of 2035. This means more than a 250-fold increase from the 2024 level.

Why İs Offshore Floating PV Becoming Widespread?

Due to land constraints, freshwater evaporation, and grid connection costs, offshore solutions are coming to the fore. According to the Offshore Energy Storage Market report, the offshore energy storage market will grow 14.68% annually until 2035.
