Solar electrical generation systems include arrays of what to produce an electric current?

The correct answer is the term commonly used to refer to the technology that converts sunlight directly into electricity through the photovoltaic effect. Photovoltaic panels, often simply called solar panels, consist of many solar cells that capture sunlight and generate direct current (DC) electricity. This technology is widely utilized in residential and commercial solar power systems because of its efficiency and established performance in harnessing solar energy.

In contrast, options such as phototropic concentrator panels and thermal hybrid solar collectors represent different technologies that may involve solar energy but do so in other ways. Phototropic concentrator panels are designed to track sunlight and may not directly convert solar energy into electricity as photovoltaic panels do. Similarly, thermal hybrid solar collectors are primarily used for heating water or air rather than generating electrical power.

By focusing on the specific function and design of photovoltaic panels, it becomes clear why this answer is the most accurate representation of the technology used for generating electric current from solar energy.
