What does solarize mean?
Solarize is a verb meaning to expose something to sunlight or, in contemporary environmental contexts, to convert a building or system to solar power. Its older agricultural sense refers to treating soil by exposing it to the sun's heat, often to prepare it for planting. The word can also have a figurative or technical use when describing the adaptation of roofs, appliances, or industrial processes to solar energy. Although solarize is less common than solar or sunlight, it is useful because it identifies a process rather than merely describing the presence of sunlight. In its modern sense, it often carries an association with renewable energy, energy efficiency, and reducing dependence on conventional electricity.
To expose something to sunlight, especially in order to treat or prepare it.
"They solarized the soil for several days before sowing the seeds."
This sense is traditional in agriculture and some industrial processes.
To convert a building, device, or system so that it uses or is adapted for solar power.
"The owners solarized the house by installing panels and an efficient battery system."
This is a common modern use in discussions of renewable energy and off-grid power.
Solarize sounds like an unusual verb, but it literally means to put something in the sun.

Etymology of solarize
Solarize is derived from solar, which comes from Latin solaris, meaning “of or relating to the sun” and ultimately from sol, meaning “sun.” The verb-forming suffix -ize was added during the modern English period, following the widespread English use of such verbs to indicate making, applying, or treating something in a particular way. The related English noun solarium is a room or building designed to admit abundant sunlight.
