Solar energy is the energy that comes from the sun and is a renewable energy source. When sunlight passes through the Earth's atmosphere, it becomes visible light and infrared radiation. Plants use this energy to create sugar and starches, which is called photosynthesis. Solar cell panels then convert this energy into electricity.
Solar thermal energy systems use sunlight to heat a fluid, which can then be used to create steam and power a turbine to generate electricity. This technique is often used in large-scale solar power plants, such as concentrated solar power (CSP) systems, which use mirrors or lenses to concentrate sunlight.
CSP involves using lenses or mirrors to concentrate sunlight into a small beam, and tracking systems to follow the sun's movement. The heat of this beam is then used to heat a fluid to generate electricity.
You can use solar energy for things like outdoor lights, device chargers, and small appliances. For example, you can use solar walkway lights, string lights, or twinkle lights to add ambience to your yard. Solar power banks can charge phones and other small devices, and solar generators can power small appliances like coffee makers, fans, and laptops. You can also add renewable energy to your home with a solar water heater.
