Solar-powered devices use energy from the sun to operate. They are equipped with solar panels that convert sunlight into electricity, making them an eco-friendly alternative to traditional power sources. Common examples include solar calculators, solar lights, and solar chargers for electronic devices. These devices are particularly useful in remote areas where electricity may not be readily available. By harnessing renewable energy, solar-powered devices help reduce reliance on fossil fuels and lower carbon emissions, contributing to a more sustainable future. They are increasingly popular for both personal and commercial use, promoting energy efficiency and environmental conservation.
