Scientific experiment using solar energy to generate electricity

Do solar cells generate a lot of power?

(Note: because of the spectrum of light emitted, solar cells do not generate as much power from CFL or LED bulbs, but you will still be able to make measurements for purposes of a science project). Note Before Beginning: This science fair project requires you to hook up one or more devices in an electrical circuit.

How do you use solar power?

Experiment with solar power by building your own solar-powered robot or oven or by testing ways to speed up an existing solar car. Or analyze how solar cells or panels work. Now You're Cooking! Building a Simple Solar Oven Here is a project that uses direct solar power, gathering the sun's rays for heating/sterilizing water or cooking.

How do solar cells work?

Solar cells are an alternative method for generating electricity directly from sunlight. With this project, you can get down to the atomic level and learn about the world of solid-state electronics as you investigate how solar cells work. Your experiment will measure the effect of changing light intensity on power output from the solar cell.

Do solar panels produce electricity?

Solar panels are capable of producing electricity from not only sunlight, but also from artificial light sources. The amount of voltage produced from a small solar panel is surprisingly good, however, the amount of current produced from this same solar panel is minimal.

How do I set up a solar cell experiment?

Set up your experiment, as shown in Figure 1. Set up your lamp a fixed distance from where you will test the solar cell. If you are doing the project outside, set up your experiment in an area with direct sunlight. Connect your multimeter's leads to the solar cell's alligator clip leads.

Are solar-powered robots a 'green' energy source?

You have probably heard about using renewable energy sources like wind and solar power to provide electricity to homes and buildings, as well as hybrid or fully electric cars that use less (or zero) gasoline. But what about solar-powered robots? As robots become more common, it is increasingly important to use "green" energy sources to power them.
