Question

1. what is used at the solar one facility in california to concentrate the suns rays?

○ pv cells
○ batteries
○ mirrors
○ turbines

Explanation:

The Solar One facility is a concentrating solar power (CSP) plant. It uses large mirrors (heliostats) to reflect and concentrate sunlight onto a central receiver to generate energy. PV cells convert light directly to electricity without concentration, batteries store energy, and turbines are used to convert thermal energy to electrical energy after concentration, not to concentrate the sun's rays.

Answer:

B. mirrors
