Unit 3 : Solar Energy Full Pdf ✅
.
Solar energy is a renewable and sustainable power source harnessed from the sun's rays using technologies such as photovoltaic (PV) panels and solar thermal systems. PV panels convert sunlight directly into electricity, while solar thermal systems use solar energy to heat fluids, producing steam for electricity generation. Solar energy is clean, producing no greenhouse gas emissions during operation, which helps mitigate climate change. It has seen significant growth due to declining costs and technological advancements. Solar energy can be deployed on a small scale, such as rooftop installations, or large scale, like solar farms. It provides energy security and can reduce electricity bills for consumers. However, it also faces challenges like intermittent availability and the need for efficient energy storage solutions to provide a consistent power supply.
