Questions about this item

What does the 2.5 W rating mean when the panel is installed in a project?

The 2.5 W rating is the maximum output under standard test conditions; real-world output will be lower depending on sun angle, temperature and shading.

What does the 18 V specification limit in practice?

The 18 V open-circuit voltage determines the maximum voltage the panel can present to a charge controller or load; any connected regulator must accept at least 18 V input.
