What are Solar Panels?

Solar panels are photovoltaic devices that convert incident solar irradiance into electrical energy through the photovoltaic effect. Semiconductor junctions within the cells generate electron-hole pairs when exposed to light, producing a direct current output. Multiple cells are interconnected and encapsulated to form modules capable of delivering usable power levels for a wide range of electrical systems.

The electrical behavior of solar panels is governed by semiconductor material properties, cell architecture, and interconnection topology. Parameters such as voltage, current, and efficiency depend on irradiance and temperature conditions, while mechanical characteristics define durability under environmental stress. Proper selection of these parameters ensures compatibility with power electronics interfaces, system voltage levels, and long-term reliability requirements.
