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.

One of the main advantages of off-grid solar systems is energy independence. Homeowners and communities can produce their own electricity without relying on utility companies. This autonomy is especially beneficial in remote areas where extending the power grid can be prohibitively expensive. By installing an off-grid solar system, residents gain control over their energy source, insulating themselves from fluctuating energy prices and potential outages caused by extreme weather or infrastructure issues.
