Aurinkokennojärjestelmät

Aurinkokennojärjestelmät, commonly known as solar panel systems, are photovoltaic (PV) systems designed to convert sunlight directly into electricity. These systems are a key component of renewable energy production. A typical solar panel system consists of several interconnected solar panels, an inverter, and mounting hardware. The solar panels themselves are made up of photovoltaic cells, usually silicon-based, which exhibit the photovoltaic effect. When photons from sunlight strike these cells, they dislodge electrons, creating a direct current (DC) flow.

The direct current produced by the panels is then fed to an inverter. The inverter's primary function is to convert this DC electricity into alternating current (AC) electricity, which is the standard form of electricity used in homes and businesses and by the electrical grid. The AC electricity can then be used immediately to power appliances, or it can be fed into the public electricity grid. In some systems, battery storage can be incorporated to store excess energy generated during daylight hours for use at night or during periods of low sunlight.

The efficiency and output of an aurinkokennojärjestelmä depend on various factors, including the quality and type of solar panels, the angle and orientation of the panels relative to the sun, the amount of sunlight received, and any shading. Installation is typically done on rooftops or on the ground in areas with good sun exposure. These systems are environmentally friendly, producing clean energy with no greenhouse gas emissions during operation, and are becoming increasingly popular as a sustainable energy solution.
