"Solar Power" Is A Song About Embracing The Start Of Warmer Weather And The Freedom And Joy Associated With It. The Lyrics Suggest That With The Improved Weather Comes Increased Confidence In Oneself As Well As Boldness And Adventure. She Implies That She Is A "prettier Jesus" That Can Lead Others In The Same Kind Of Liberation. She Encourages The Listener To Forget Their Worries And Live In The Moment And Trust The "new Kind Of Bright" That Comes With Solar Power. The Song Is Upbeat And Serves As A Reminder To Take Advantage Of The Summer And Make Lasting Memories Freed From The Constraints Of Modern Life.
