Morphology

solar = sol (transparent) = sol + ar

The word 'solar' is transparently derived from 'sol' with the suffix '-ar' indicating 'relating to'.

Etymology

Solar comes from the Latin root sol, which means 'sun' and is the same sol you hear in Spanish. So solar means 'from the sun' and is used for sunlight, heat, or energy that comes from the sun.
