What does a solar array consist of?

A solar array is composed of a set of solar panels that work together to capture sunlight and convert it into electricity. These panels are typically made up of photovoltaic cells that generate direct current (DC) electricity when exposed to sunlight. The collective arrangement of these panels enhances the efficiency and output of electricity generation, allowing for enough power to be produced for residential, commercial, or even utility-scale applications.

In contrast, the other options refer to unrelated systems of power generation or distribution. Wind turbines are associated with harnessing wind energy, geothermal heat pumps pertain to extracting heat from the ground, and traditional power lines are used for transmitting electricity from power plants to consumers but do not generate electricity themselves. The correct identification of a solar array's components is essential for understanding renewable energy systems and their design.
