Fotovoltailised

Fotovoltailised, also known as photovoltaic (PV) systems, are devices that convert sunlight directly into electricity using the photovoltaic effect. This process occurs when photons from sunlight excite electrons in a semiconductor material, such as silicon, causing them to flow and generate an electric current. The basic components of a photovoltaic system include solar panels, an inverter, and sometimes a battery storage system.

Solar panels are the primary component, consisting of multiple solar cells. Each cell is typically made from silicon and is designed to capture sunlight and convert it into direct current (DC) electricity. The DC electricity produced by the solar panels is then converted into alternating current (AC) electricity by an inverter, which is suitable for use in homes and businesses.

Photovoltaic systems can be categorized into two main types: grid-tied and off-grid. Grid-tied systems are connected to the utility grid and can feed excess electricity back into the grid, often earning credits or payments from utility companies. Off-grid systems, on the other hand, are not connected to the grid and rely on battery storage to store excess energy for use when sunlight is not available.

The efficiency of photovoltaic systems refers to the percentage of sunlight that is converted into usable electricity. Advances in technology have led to improvements in efficiency, making solar panels more cost-effective and environmentally friendly. Additionally, the scalability of photovoltaic systems allows for a wide range of applications, from small rooftop installations to large solar farms.

Overall, fotovoltailised systems offer a renewable and sustainable source of electricity, contributing to the reduction of greenhouse gas emissions and dependence on fossil fuels. As technology continues to advance, the adoption of photovoltaic systems is expected to grow, further integrating solar energy into the global energy mix.
