1. The Sun Provides More Energy Than We Need
- In just one hour, the sun gives more energy to Earth than the entire world uses in a year.
- This means solar power has limitless potential if harnessed properly.
2. Solar Energy Is a Renewable Resource
- Unlike coal or oil, solar energy will never run out (for the next ~5 billion years).
- It’s one of the cleanest forms of energy available.
3. Solar Panels Work Using the Photovoltaic Effect
- When sunlight hits a solar cell, it excites electrons and creates electricity.
- This process is called the photovoltaic effect, discovered in 1839 by Edmond Becquerel.
4. Solar Energy Powers Big Things
- It’s not just for calculators and lights—entire homes, offices, and even satellites use solar power.
- The International Space Station (ISS) is powered entirely by solar energy.
5. India Is a Global Leader in Solar Power
- India has the world’s largest solar power park (Bhadla Solar Park in Rajasthan).
- The country is targeting 500 GW of renewable energy capacity by 2030.
6. Solar Power Can Save Money
- After the initial setup, solar panels reduce electricity bills significantly.
- Government subsidies make it even more affordable for homes and schools.
7. Solar Panels Need Sunlight, Not Heat
- Even on cold days, solar panels generate power if sunlight is present.
- They often perform better in cooler climates because heat can reduce efficiency.
8. Solar Power Is Now Used in Vehicles
- Some cars, boats, and airplanes use solar power.
- Example: The Solar Impulse 2 was the first plane to fly around the world using only solar energy.
9. You Can Power a House with Just the Roof
- A well-designed solar rooftop can power an entire home, including fans, lights, TV, fridge, and even ACs.
10. Solar Energy Teaches Physics, Chemistry & Environment
- It involves concepts of:
- Energy transformation (light to electricity)
- Semiconductors (silicon use in PV cells)
- Sustainability and green energy
