Solar Panels

Definition

Solar panels are devices that convert sunlight into electricity, utilizing photovoltaic (PV) cells made primarily from silicon. They play a crucial role in harnessing renewable energy, reducing reliance on fossil fuels, and contributing to energy-efficient systems within buildings, impacting aspects like HVAC and lighting. By generating clean energy from the sun, solar panels not only help in energy conservation but also present challenges and opportunities for implementing sustainable solutions across various sectors.
