Solar-based projects harness the power of the sun to create sustainable and eco-friendly solutions. These projects include solar-powered devices such as street lights, water heaters, and battery chargers, as well as more complex systems like solar tracking mechanisms and photovoltaic power generation. Solar tracking systems use sensors to optimize the position of solar panels for maximum energy absorption. Solar-powered irrigation systems provide water to crops in rural areas, reducing energy costs. These projects are ideal for promoting renewable energy use and addressing global environmental challenges, making them popular in both educational and professional settings.
