Solar panels might look like sleek glass tiles sitting on rooftops, but inside, there’s some fascinating science at work. Let’s make it simple.
1. The Sun’s Energy Hits the Panel
- Sunlight carries tiny packets of energy called photons.
- When photons hit a solar panel, they knock loose tiny particles inside called electrons.
Think of it like sunlight “waking up” the panel to start producing power.
2. The Solar Cells Do the Magic
- Solar panels are made up of smaller units called solar cells.
- When photons hit the silicon, electrons start moving—this movement creates direct current (DC) electricity.
3. The Inverter Converts the Power
- Homes and businesses don’t use DC electricity directly—they use alternating current (AC).
- An inverter connected to your panels changes DC into AC so your lights, appliances, and gadgets can use it.
4. Powering Your Home (and Beyond)
- Once converted, the electricity flows into your home’s electrical panel.
- Any extra power you don’t use can go back to the grid (in many regions, you even earn credits through net metering.
5. The Cycle Keeps Repeating
As long as the sun shines—even on cloudy days—your solar panels keep generating clean, renewable energy.
