Solar radiation is the energy emitted by the Sun in the form of light and heat. This energy travels through space and reaches the Earth, where it plays a crucial role in supporting life. Plants use solar radiation for photosynthesis, converting sunlight into energy, which forms the basis of the food chain. The amount of solar radiation that reaches the Earth's surface varies based on factors like location, time of year, and weather conditions. This energy can be harnessed using solar panels, which convert sunlight into electricity, providing a clean and renewable source of energy for homes and businesses.
