Solar Powered Airplanes Keywords: airplanes, estimation, solar cells, solar energy

If we were to coat a Boeing 747 jumbo jet with solar panels, is it possible to fly it using only the energy generated by these solar panels?

This module introduces the concept of estimation, both in the sense of rounding extremely precise numbers off to remove excessive significant figures, and simplifying a complex process (the flight of a 747) to a simpler one, by evaluating the possibility of powering a 747 with solar panels.

Solar Energy in a Temperate Climate. Keywords: photovoltaic cell, solar cells, solar energy, solar radiation

Does it pay to cover your roof with solar panels in Vancouver?

We show the example calculation of expected amount of energy, which can be obtained in Vancouver from a roof covered with solar cells.

Renewable Energies Keywords: biofuel, electricity generation, energy, hydro-electricity, Renewable, solar energy, wind energy

Energy is always required, whether it be for the production of goods, the supplying of services, or for transportation. Can we reduce our emissions by turning to clean sources of energy? If so, why haven't we already?

A large portion of humanity's energy demands are met using fossil fuels. Switching from fossil fuel generation to cleaner sources could greatly reduce the carbon emission put out every year. There are many ways to obtain energy cleanly, each with their own advantages and challenges.

Capturing Solar Energy with Photovoltaic Cells Keywords: Lend an Experiment (LEx), photovoltaic cell, photovoltaics, resistance, solar, solar cells, solar energy

Did you know that the amount of power from a solar panel depends on what it's connected to? Explore how photovoltaic panels work, converting light into electrical energy, and learn how you can find the maximum power output from a solar panel.

This activity is part of the LEx (Lend an Experiment) Climate Kit. Students use solar panels to generate electrical power, exploring how light energy can be turned into electricity. Students connect the photovoltaic cells to different loads to find their peak power output.
