5. Validate Feasibility
   • Check if materials are affordable and available.
   • Estimate time required.
   • Consult a teacher or mentor to refine the idea.

What Is Solar Energy?

Solar energy comes from the sun’s rays. Photovoltaic (PV) panels turn sunlight into electricity. Solar thermal systems use sunlight to heat water or air.

Types of Solar Energy Projects

1. Solar PV Circuits – powering LEDs, small motors, or chargers.
2. Solar Thermal Builds – sun-powered water heaters or cookers.
3. Tracking Systems – mounts that follow the sun for higher efficiency.
4. Integrated Systems – combining solar with microcontrollers (e.g., Arduino, Raspberry Pi).
5. Off-Grid Solutions – portable solar kits for camping or emergency use.
