Solar Lantern Building: Harnessing the Power of the Sun

In this engaging and educational activity for young minds aged 11 to 16, we will learn about the fascinating world of photovoltaic energy by assembling our solar lantern. Please note that soldering is involved, so it's crucial to have safety instructions and adult supervision during the activity. If you cannot access the solar lantern kit, don't worry! We will also explore an alternative method using sunlight refraction. Let's dive into the world of renewable energy!

Develop these Key Competencies:

  • Critical Thinking
  • Problem Solving

Materials needed

  • Solar lantern kit (containing cables, circuit board, switch, LED bulb, battery, solar panel, and flashlight housing)
  • Soldering iron and soldering tin


For Moser lamp alternative:

  • A PET bottle (any size, preferably transparent)
  • Tap water
  • Small cardboard box (proportional to the bottle)
  • Scissors or cutter
  • Pen or pencil
  • Chlorine (optional for practical application but handle with care
Activity Description


Step 1: Safety First

  • Before starting, review the safety instructions with your adult supervisor. Ensure you have the necessary safety equipment and proper guidance during the activity, especially when using the soldering iron.

Step 2: Assemble the Solar Lantern

  • Follow the instructions in your solar lantern kit to assemble the components. Connect each part using the soldering iron and soldering tin.
  • Once the solar lantern is complete, you can add your creative touch by constructing a lampshade or housing to enhance its appearance.

Step 3: Moser Lamp Alternative

  • If you don't have access to the solar lantern kit, you can learn about the Moser Lamp model, which can be a valuable resource for communities without electricity. (A link to the Moser Lamp model page will be provided).

Step 4: Evaluation

  • Test your solar lantern by switching it on. Witness the power of the sun lighting up your creation!



Discover the incredible potential of solar energy. The amount of solar energy reaching the Earth's surface is vast, far surpassing the combined energy from all non-renewable resources like coal, oil, and natural gas. Solar energy is a sustainable and powerful alternative for our energy needs.



Additional Activities - Moser Lamp:

For those looking at the Moser Lamp alternative, please follow the instructions to construct a simple yet effective solar lamp using a PET bottle, water, cardboard box, and sunlight refraction.


Safety Note - When working with chlorine for the Moser Lamp model, exercise extreme caution as it is toxic. Ensure it is handled safely, and the water mixed with chlorine is not consumed.

Relevant information if you are facilitating

This activity allows participants to gain hands-on experience in building a solar lantern and understanding the significance of photovoltaic energy. It also introduces an alternative method through the Moser Lamp model, promoting resourcefulness and creativity.
