Photovoltaic panel assemblies are devices that convert sunlight directly into electricity. They consist of thin, solid semiconductor layers—most commonly silicon—that generate direct current when exposed to light. Unlike traditional power sources, these panels have no moving parts, which means they can operate efficiently for many years without degradation or maintenance. Simple photovoltaic cells are often used in small electronics like calculators and digital watches, while more advanced systems power homes, businesses, and even entire electrical grids. These panels can be manufactured in various shapes and sizes, and multiple units can be connected in series or parallel to increase energy output. In recent years, the integration of photovoltaic technology into buildings has become increasingly common, with panels installed on rooftops, walls, windows, and even as part of skylights or shelters. This type of system is known as building-integrated photovoltaics (BIPV), offering a sustainable and aesthetically pleasing way to generate clean energy.
