Solar energy

• What do solar panels generate when light is directed at them?


  Electric current
• Why is the sun considered a great energy resource?


  It releases a huge amount of energy and heats the planet
• How long is the sun expected to last?

  Millions of years
• How do solar panels harness energy from the sun?


  By converting it into electric current
• What happens when light falls on solar panels?


  Electrons are released within the material
• What is a limitation of solar panels compared to other energy resources?


  They don't produce much electricity
• In what ways are solar panels used in the UK?


  They contribute to the National Grid and power individual homes and devices
• What do solar farms do?


  They contribute to the National Grid and require hundreds of panels
• How do solar farms optimize energy collection?


  They move to face the sun
• How do roof panels benefit individual homes?


  They reduce reliance on the National Grid
• What devices can use solar panels?


  Calculators, traffic lights, smart watches, and power banks
• What is a disadvantage of solar panels on cloudy days?


  The electricity generated is greatly reduced
• Why do solar panels produce less current on cloudy days?


  There is less sunlight available
• Can solar panels completely stop producing electricity on cloudy days?


  No, they will still produce some electricity
• How do some countries adapt their energy systems for solar energy's unreliability?


  They use solar energy as a substitute for fossil fuels when conditions allow
• What is a key advantage of solar energy over fossil fuels?


  Solar energy is renewable and clean
• What is a key disadvantage of fossil fuels compared to solar energy?


  Fossil fuels are not renewable
• How can homes with solar panels switch between energy sources?


  They can use fossil fuels on cloudy days and solar power on sunny days
• What are the overall advantages and disadvantages of solar energy?


  Advantages:

  • Clean and renewable
  • No pollution
  • Near limitless energy source
  • Easy to set up

  
  

  Disadvantages:

  • Weather dependent
  • Low energy gain
  • Requires many panels to match fossil fuel output
• What is a key feature of solar panel installation?


  Parts can be manufactured off-site
• Why is solar energy considered near limitless?


  Because it comes from the sun
• What is the main reason solar panels are not more commonly used?


  They are weather dependent
• What is the role of an AI tutor in the context of exam preparation?


  To support students and keep them motivated
• What features does the Smart Learning platform offer?


  Interactive quizzes, easy-to-follow videos, and AI tutor support
• What is the purpose of the Launchpad learning platform?


  To help students achieve top results in their exams
