Morphology
The meaning is directly compositional: 'solar' = pertaining to the Sun and 'facula' = a bright region, so together they denote a bright area on the Sun. This adjective+noun pattern is a transparent, regular formation (though 'facula' is a technical term, if a learner knows both constituents the overall meaning is immediately inferable).
Etymology
Solar facula comes from the Latin word facula, meaning 'little torch'. These bright patches look like small lights near sunspots, so the name helps you remember they are 'bright areas' on the Sun.
