In this workshop students will learn to make a Solar based Portable Mobile charger.

Students learn about Solar Energy creating their own Solar based Portable Mobile charger. Students will study the solar energy, solar Panel & use of solder gun. In this lesson, students will conceptualize and then turn their ideas into real-life models.

What You'll Need

– Solar panel 6V

-IC 7805

– USB Port

– Wires

– Celotape

– Glue gun &glue stick

– Solder Gun

– Wire cutter/stripper

The Instructions

Discuss with students about sources of energy.

You can refer attached ppt

Discuss with them all renewable & non-renewable energies. 

Make awareness to use solar energy which is renewable energy.

Tell them advantages of using solar energy. 

Discuss how to convert solar energy into electricity.

Tell them brief concepts of Solar Panels & how solar energy convert into electricity by using Solar Panels, what are the ratings of solar panels.

In summer season there are lots of heat & light is available.

We can made solar mobile charger for surviving in summer from heat when we are outside of home.

Make connections of all components.

See connection diagram from attachment.

make sure students make connection & soldering properly.

After connection introduces them with IC 7805 & its function.

Let’s Start assemble it.

Now test solar mobile charger.


  • (MS-ETS1-1): Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
  • (MS-ETS1-2): Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
