What you need

Cardboard sheet, tiny solar cells, led, thin insulated wire or alligator clip leads, clear tape, scissors, ruler, pencil, glue, colouring materials, aluminium foil optional, adult supervision required

Step 1

Lay out all your materials on a clean flat table so you can see everything.

Step 2

Use the pencil and ruler to draw four walls one floor and one roof panel for a small house on the cardboard.

Step 3

Cut out the drawn cardboard pieces carefully to separate the walls floor and roof.

Step 4

Fold and glue the walls to the floor to make a little house box and hold until the glue sticks.

Step 5

Decorate the outside of your house with colouring materials to make it look fun and bright.

Step 6

Choose a flat spot on the roof and mark where you will attach the solar cell or cells.

Step 7

Tape the solar cell or cells to the marked spot on the roof leaving the metal tabs or wire ends free to connect.

Step 8

Look at the LED and find the longer lead which is positive and the shorter lead which is negative.

Step 9

Find the two metal tabs on the solar cell and decide which is positive and which is negative by looking for tiny plus or minus signs or the printed markings.

Step 10

Connect the solar cell positive tab to the LED longer lead and the solar cell negative tab to the LED shorter lead using alligator clip leads or taped wires so the connections are secure.

Step 11

Take your house into bright sunlight and tilt the roof toward the sun to see if the LED lights up and try using folded aluminium foil as a reflector if the light is dim.

Step 12

Take a photo or video and share your finished solar house creation on DIY.org

What can we use if we can't find a small solar cell or alligator clip leads?

Salvage the solar panel from a garden stake light (removing its metal tabs) and use insulated copper wire or tape the LED leads directly to the solar cell tabs instead of alligator clip leads, following the 'tape the solar cell' and 'connect... using alligator clip leads or taped wires' steps.

Why won't the LED light even in bright sun and how can I fix it?

Check that the LED's longer lead is connected to the solar cell's positive tab and the shorter lead to the negative tab using secure clips or taped wires, ensure the roof is tilted toward the sun and not shaded, and try using folded aluminium foil as a reflector as suggested if the light is dim.

How can I adapt this activity for younger children or challenge older kids?

For younger kids, have an adult pre-draw and pre-cut the cardboard, use glue sticks and stickers for the 'fold and glue' and 'decorate' steps and let them tape the solar cell in place, while older kids can design multi-panel roofs, wire multiple solar cells in series or parallel and measure voltage with a multimeter after 'find the two metal tabs' and 'connect' steps.

What are some ways to extend or personalize the solar house after it's working?

Add extra LEDs on different walls wired in parallel, install a small toggle switch between the solar cell tabs and the LED leads, make a larger aluminium foil reflector per the 'folded aluminium foil' suggestion, or cut window shapes and insert colored cellophane before photographing your finished solar house.

Facts about solar energy and electronics for kids

☀️ In just one hour the sun delivers more energy to Earth than humanity uses in a whole year — that’s a lot of sunshine to catch!

🔋 A small solar cell in bright sunlight can make enough electricity to light a tiny LED — perfect for model houses.

🏠 Passive solar design (using windows, insulation, and building shape) can heat a home without any electricity.

📦 Cardboard is a favorite for models because it’s lightweight, easy to cut and glue, and helps show how insulation works.

🔬 The photovoltaic effect that makes solar cells possible was discovered way back in 1839 by Edmond Becquerel.

How do I design and build a small solar house model that powers an LED?

Start by sketching your house layout and where the solar cells will sit, usually on the roof. Cut and assemble cardboard walls and roof with glue or hot glue. Mount tiny pre-tabbed solar cells on the roof, wire them (parallel for more current or series for more voltage), add a small switch or resistor, and connect to an LED. Make a removable roof or access panel for testing. Place the model in direct sunlight or under a bright lamp to test and adjust panel angle for best light.

What materials do I need to build a model solar house with an LED?

You’ll need sturdy cardboard or foam board, small pre-tabbed solar cells or a tiny solar panel, an LED, hookup wire, and a small switch or resistor. Also gather scissors or a craft knife (adult use), glue or hot glue, tape, ruler, pencil, and paints or markers for decoration. Optional items: clear plastic for windows, a tiny battery holder for cloudy tests, electrical tape, and small clips. Use low-voltage components and child-safe supplies.

What ages is this solar house model activity suitable for?

Suitable for children about age 6 and up with adult supervision. Ages 6–8 can plan, decorate, and help assemble while adults handle cutting and wiring. Ages 9–12 can take on more construction and basic wiring with guidance. Teens (13+) can design circuits, experiment with panel orientation, and troubleshoot more independently. Always supervise use of sharp tools, hot glue, and small parts, and tailor complexity to the child’s skills and interest.

What safety tips should parents follow when kids build a solar house model?

Supervise cutting, hot glue, and any electrical work; consider pre-tabbed panels to avoid soldering. Use low-voltage LEDs and panels to reduce risk and keep small parts away from toddlers to prevent choking. Protect eyes from bright sunlight during outdoor testing and avoid looking at reflective panels. Choose non-toxic paints and adhesives, secure loose wires, and teach children to disconnect panels before adjusting wiring. Follow all manufacturer instructions for electronic components.
