Terreno vs. parcela vs. solar
While terreno, parcela, and solar can all be translated as plot or land, they are not interchangeable in Spanish. The main differences lie in their generality, legal definition, and intended use, particularly whether they are rural or urban and designated for construction.
Terreno
A2Terreno is the most general and widely used term for land or ground. It can refer to any piece of land, regardless of its location (rural or urban), size, or use. It often emphasizes the physical surface or the area itself.

(We bought a large piece of land near the lake for camping.)

(The hike was difficult due to the rocky and steep terrain.)

(The land/soil in this region is very fertile for growing potatoes.)

(The city council provided a piece of land to build a new sports center.)
Parcela
B1Parcela refers to a plot or parcel of land that is a smaller, clearly defined part of a larger area. It implies a division and usually has legal or administrative boundaries. It is commonly used for both agricultural land and individual lots in a housing development.

(Each plot in the project has its own cadastral registration number.)
Solar
B2Solar is a very specific term for a building plot or vacant lot located within an urban or urbanizable area. Its key characteristic is that it is designated and ready for construction. It is often an empty space where a building could be built, or where one was previously demolished.

Summary
In short: Terreno is the general word for any land or terrain. Parcela is a legally divided plot, often agricultural or part of a development. Solar is specifically an urban, buildable, and often vacant, plot of land.
