If your invention is "new and non-obvious" as compared to anything ever used in public or disclosed in any publication anywhere in the world, or anything equivalent, and not an obvious combination or improvement of any of the above, then go see a patent attorney for actual legal counsel on the best way to proceed. The specific form and process varies from one country to another.
Solar-powered lights have been "well known in the art" for a long time.
