Heliostat
A heliostat is a special mirror system used in large solar power plants. Think of it as a smart mirror that automatically follows the sun throughout the day, like a sunflower. These mirrors reflect sunlight onto a central tower or receiver, which then converts this concentrated solar energy into electricity. When you see this term in a resume, it usually relates to someone who has worked with solar power plants, particularly with concentrated solar power (CSP) systems. Similar terms you might see are "solar tracking mirrors" or "solar reflectors."
