No need to go so far. There's enough desert type land in Spain that isn't really useful for anything else. Covering it with solar panels may actually improve the ecosystem, as shrubbery could grow underneath it (or use semi-transparent panels mounted 10m above the ground, and you'd have a nice greenhouse). Musk claimed the entire US could be run on solar power with a 100 square mile (258 km2) patch of land - that's smaller than Malta. Batteries to ensure a continuous supply would need 1 square mile.
