The build

Step 01

Wire the pump

Connect the pump to the solar panel.

Step 02

Set up tubing

Run a tube from the lower to upper container.

Step 03

Place in sun

Aim the panel at the sun.

Step 04

Pump water

Watch water lift to the top.

Working Principle

The panel converts sunlight to electricity that runs the pump, lifting water uphill with no fuel — just sun.

The science behind it

A closer look

Photovoltaic power can drive useful work directly; output (and pumping rate) rises with sunlight intensity.

Variables to test

  • 1 Compare cloudy vs sunny pumping rate.
  • 2 Lift water higher — does flow drop?
