Another element affecting solar panel pricing is the scale of production. As the demand for solar technology has grown, economies of scale have come into play, driving down the cost of manufacturing. Major manufacturers can produce panels more cheaply due to high production volumes, therefore offering better prices to consumers. Market competition also plays a significant role; as more companies enter the solar market, they often engage in price wars, leading to lower costs for the end consumer.

Semiconductor materials, such as silicon, gallium arsenide, and cadmium telluride, are commonly employed in the manufacturing of solar cells. Each material has a specific bandgap that dictates its efficiency in converting sunlight into electricity. Silicon, for example, has a bandgap of about 1.1 eV, which allows it to effectively utilize a significant portion of the solar spectrum. However, while silicon-based solar cells dominate the market due to their cost-effectiveness, they often operate at efficiencies around 15-22% in real-world conditions.
