Question

solar panels are the most useful in states such as sunny california, what evidence did you observe that supports this claim? (select all that apply)

solar panels only produced energy on sunny days

solar panels did not produce energy on sunny days

clouds kept the solar panels from producing energy

clouds helped the solar panels produce energy

Explanation:

Solar panels rely on sunlight to generate energy. Evidence supporting their usefulness in sunny areas would link sunny conditions to energy production or cloudy conditions to reduced production. "Solar panels only produced energy on sunny days" directly shows sunlight is necessary, and "clouds kept the solar panels from producing energy" shows clouds hinder production—both support the claim that sunny regions (like California) make solar panels most useful. The other options contradict this logic.

Answer:

solar panels only produced energy on sunny days, clouds kept the solar panels from producing energy
