fotovoltaikák

Fotovoltaikák, often referred to as solar panels, are devices that convert sunlight into electricity through the photovoltaic effect. This process utilizes semiconductor materials, typically silicon, which absorb photons from sunlight. When photons strike the semiconductor material, they excite electrons, causing them to flow and generate an electric current. This direct current (DC) can then be used directly, stored in batteries, or converted to alternating current (AC) for use in homes and businesses or for feeding into the electrical grid.

The efficiency of photovoltaic cells, and thus the panels they form, has steadily increased over the years due to advancements in material science and manufacturing techniques. Factors influencing a panel's energy production include the intensity of sunlight, the angle of incidence, temperature, and the panel's surface cleanliness. Photovoltaic systems are a key component of renewable energy strategies, offering a clean and sustainable way to generate power with minimal environmental impact during operation. Their widespread adoption contributes to reducing reliance on fossil fuels and mitigating greenhouse gas emissions.
