päikeseenergial

Päikeseenergia is the Estonian term for solar energy. It refers to the radiant energy emitted by the Sun that can be harnessed and converted into usable forms of power. This energy is produced through nuclear fusion reactions occurring within the Sun's core.

The primary methods for utilizing päikeseenergia involve photovoltaic (PV) panels and solar thermal systems. Photovoltaic panels directly convert sunlight into electricity using the photovoltaic effect, where photons from sunlight strike semiconductor materials and dislodge electrons, creating an electric current. These panels are commonly seen on rooftops and in large solar farms.

Solar thermal systems, on the other hand, capture the Sun's heat. This heat can be used for direct applications such as heating water for domestic use or swimming pools, or it can be used to generate steam to drive turbines for electricity production in concentrated solar power (CSP) plants.

Päikeseenergia is considered a renewable energy source because the Sun's energy is virtually inexhaustible on a human timescale. Its use contributes to reducing reliance on fossil fuels, thereby mitigating greenhouse gas emissions and combating climate change. Estonia, like many countries, is increasingly investing in and utilizing päikeseenergia to diversify its energy mix and promote sustainable development. The availability and efficiency of päikeseenergia in Estonia are influenced by geographical location, weather patterns, and seasonal variations in sunlight.
