Solar lamps are a type of lamps which use solar energy to provide illumination. They are used in areas where electricity is not available, such as remote homes, outdoor areas and other places. A solar lamp typically consists of a light source like a LED lamp, a solar panel and a battery. When solar light hits the solar panel, the solar panel will convert the light energy into electrical energy and store it in the battery. At night or when the environmental light is not enough, the battery will provide the power to the LED lamp. The advantages of solar lamps are that they are eco-friendly. No toxic or hazardous emissions are produced during the generation or use of solar lamps. They are also cost effective, as you dont need to pay the electricity bills. Moreover, they provide durable and reliable illumination. On the other hand, the installation of solar lamp can be expensive. Also, they are not suitable for places with lots of clouds, as they wont be able to generate enough power. Solar lamps are becoming increasingly popular due to their environmental and economic friendly features. They can be used for security purposes, street enlightenment, and much more. In fact, many countries are promoting the usage of solar lamps, to help reduce the dependence on traditional energy sources.
