aurinkovoimajärjestelmien

aurinkovoimajärjestelmä is a Finnish term that translates to "solar power system." It refers to a collection of components that work together to harness energy from sunlight and convert it into usable electricity. The core of any aurinkovoimajärjestelmä is the solar panel, which contains photovoltaic cells. These cells are made of semiconductor materials, typically silicon, that exhibit the photovoltaic effect. When sunlight strikes these cells, it excites electrons, generating a direct current (DC) of electricity.

For most applications, the DC electricity produced by solar panels needs to be converted into alternating current (AC) electricity, which is the standard used in homes and businesses. This conversion is performed by an inverter, another crucial component of an aurinkovoimajärjestelmä. The inverter takes the DC power from the panels and transforms it into AC power.

Other important parts of an aurinkovoimajärjestelmä include mounting structures that secure the solar panels to a roof or the ground, and electrical wiring that connects all the components. In some systems, especially those not connected to a utility grid, batteries are included for energy storage. These batteries allow the system to store excess electricity generated during the day for use at night or during cloudy periods. Grid-tied systems, on the other hand, are connected to the public electricity grid, allowing excess power to be sent back to the grid and drawn from it when solar generation is insufficient. The design and size of an aurinkovoimajärjestelmä depend on factors such as energy needs, available space, and local solar radiation levels.
