aurinkopaneelijärjestelmän
An aurinkopaneeli, or solar panel, is a device that converts sunlight into electricity using photovoltaic cells. When sunlight strikes the cells, photons knock electrons loose, creating direct current (DC) electricity. An inverter then converts DC to alternating current (AC) for use in homes and businesses. Solar panels are typically manufactured as crystalline silicon modules, assembled into arrays mounted on rooftops, ground mounts, or integrated into building facades. The main types are monocrystalline and polycrystalline silicon, which differ in cell structure and efficiency; thin-film technologies (such as CdTe or CIGS) offer flexibility but generally lower efficiency.
Performance depends on orientation, tilt, shading, and temperature. Efficiency ranges roughly as follows: monocrystalline about 20–25%,
Maintenance is relatively minimal, typically involving periodic cleaning and occasional electrical checks. Environmental and economic considerations
