aurinkopaneelin

Aurinkopaneeli, a Finnish term, translates to solar panel in English. It is a device that converts sunlight directly into electricity using photovoltaic cells. These cells are typically made from semiconductor materials, most commonly silicon. When sunlight strikes these cells, it excites electrons, creating an electric current. This direct current (DC) electricity can then be used to power electrical devices or stored in batteries. For use in typical homes and businesses, which operate on alternating current (AC), an inverter is required to convert the DC electricity from the solar panels into AC electricity.

Solar panels are a key component of solar power systems, often installed on rooftops or in solar farms. They are considered a renewable energy source because they harness energy from the sun, which is an inexhaustible resource. The efficiency of a solar panel refers to the percentage of sunlight it can convert into electricity. Technological advancements have led to increasingly efficient and cost-effective solar panels. Their widespread adoption contributes to reducing reliance on fossil fuels and mitigating greenhouse gas emissions, playing a significant role in the transition towards sustainable energy.
