Solar power is the energy obtained from the sun's rays, which can be converted into electricity or heat for various applications. It is a renewable and sustainable energy source that plays a crucial role in reducing reliance on fossil fuels and mitigating climate change. There are two primary methods for harnessing solar power: 1. **Photovoltaic (PV) Systems**: These systems use solar panels, made up of many solar cells, to convert sunlight directly into electricity.

Conversion of sunlight into useful power through photovoltaic or solar-thermal systems. A first areal estimate is annual mean irradiance times conversion efficiency and system-performance factors. Storage, transmission, land use, night-time operation and seasonal balance require separate accounting.
