⚙️ Working Principle
The solar panel works using the Photovoltaic Effect, where sunlight generates electrical energy.
Step-by-Step Operation
1️⃣ Sunlight hits the solar cells.
2️⃣ Photons excite electrons in the semiconductor material.
3️⃣ The movement of electrons produces direct current (DC) electricity.
4️⃣ The generated electricity flows through the output wires.
5️⃣ The power can be used to run small devices or charge batteries.
