Chapter Content
Solar Photovoltaic (PV) Systems: Rooftop or building-integrated PV panels generate on-site electricity.
Detailed Explanation
Solar PV systems convert sunlight into electricity using panels installed on rooftops or integrated into building materials. This allows buildings to generate their own electricity, reducing reliance on external power sources. The systems contribute significantly to energy efficiency and sustainability.
Examples & Analogies
Imagine your home having a tiny power plant on its roof that captures sunlight and turns it into electricity. Just like having a garden provides food, having solar panels generates energy, saving both money and the environment.
