There's still quite a lot of space for solar panels on land. Among the benefits of offshoring wind turbines is generally higher and more consistent wind speeds offshore, less nuisance due to noise, and the ability to construct larger, more effective turbines than is possible on land. For solar, there's not necessarily more or better sunshine offshore. There's no reason an offshore solar panel would be fundamentally different from an onshore one. And due to the much harsher environment, much of the difference between the two would relate to corrosion protection and reliability (adding to its cost). For offshore solar you'd have the complexity and cost of offshore installation and maintenance, without the clear benefit of better sun offshore. That's a hard pill to swallow when there's so much potential to have solar panels on land.
