  1. Solar Energy By: Fatima, Riah, Tannia, Aimee, and Angela

  2. How is it used to make energy? There are 3 main ways. • Solar Cells (Photovoltaic Cells) turn light directly into energy. • Glass panels, that are attached to roofs, collect the suns rays to heat water. This way you don’t need gas or electricity. • Solar furnaces use a variety of mirrors to absorb the sun’s energy. They are cut into small mirrors that produce very high temperatures.

  3. Continued • the sun can make electricity by a process called photovoltaics or PV. Photo refers to light and voltaic to voltage. • The solar energy can be used to heat your home. • The sun has special effects that go on in order to make electricity, the sun is like a big collector that turns sunlight into natural forces such as wind, rain and growing plants.

  5. How much does it cost?How much energy does it produce? • The solar energy is free. • The equipment costs several thousand dollars. • It produces 700-1000 watts per panel if it comes to money the sun does cost any dollar it’s just nature. • What it means by it’s space or movement or something like that it uses a lot of space you cant see it but it weighs a lot it takes up pretty much a lot of space. • When you aren’t that close to the sun you don’t know how heavy, big, hot..

  6. Environment and health concerns • Most of the concerns are types of skin cancer. • Skin cancer • Melanoma • Nonmelanoma skin cancers • Cataracts and other eye damage • And more • Toxic chemicals are put into solar panels. Solar panels don’t last forever sooner or later we would have to throw it out WITH the toxic chemicals.

  7. Possible Solutions • People are working on making it last longer. Solar panels currently last 25 years.

  8. Disadvantages/Negative • Too many clouds lessen the UV rays. • Pollution effects the Photovoltaic Cells. • The equipment is very pricey. • When the sun isn’t out then we can’t get any power. (Solar batteries help though)

  9. How much of Canada’s power comes from it • It can’t just randomly get power from any where. • The sun gives us a lot of energy every day in our lives.

  10. Advantages/Positive • It does not pollute the air. • It doesn’t produce carbon dioxide. • When we use glass panels to heat water we cause very little impact on the environment. • It is renewable and almost always available to use.

  11. Reliability • The solar panels work well when the sun is up and shining, but when there are clouds and when it’s nighttime it doesn’t work. • If the solar panels are blocked then it won’t work well.

  12. In what ways do you think using power from the sun changes the environment. • What is different is that we don’t plug any thing in. • Instead of using cables and that the sun is there with nothing else on it but heat.
