Solène is a French feminine name derived from the Latin sollemnis, meaning "solemn" or "dignified." Saint Solenne (Solemnis) was a 5th-century bishop of Chartres.
Solène is widely used in modern France.
Solène does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Solène reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
