The rating comes from 6 measured or published factors, each scored 0-100 against fixed reference points for its size. How we rank explains each one.
The most power independent reviewers measured from the panel in real sun. Heat, haze, sun angle and the device being charged all cut output, so 70-85% of the rated watts is a normal real-world result.
