What is Solar Power?

• Solar power is what it sounds.• Solar power is a type of energy that comes

from the sun.• Solaris is the long form of solar. • Energy is just plain energy.• Solar Power

How Does Solar Power work?

• Solar power is created when special materials called photovoltaic materials are exposed to light, such as sunlight.

• When they are exposed, they create an electric current.

• That electric current becomes light.

Where is Solar Power used?

• Solar power can be used everywhere!• You can find roofs, panels, lights and even two

way powered calculators!• Solar power is an efficient replacement to

regular circuit and series energy. • The only problem is solar items are expensive.

How much does Solar Power cost?

• Solar power is pretty expensive. It depends on what you buy.

• Solar panels can range from $150.00 to $600.00

• Solar panel are very expensive and so is the wattage.

• Solar power watts can go up from $5 – 15.00 AND THAT’S JUST ONE WATT.

Environmental and Health concerns about Solar Power

• The only problem with solar power for health concerns is the manufacturing process. We’ll explain that on the next slide.

• There are some issues, but it is by far the cleanest possible solution. There are potential pollution issues with some of the chemicals used in the manufacturing process for both the solar cells and batteries. Mining for raw materials almost always affects the environment.

• There will be less sunlight hitting the plants and animals in the areas that solar cells are deployed. Although if done properly this shouldn't be an issue.

Health Concerns about Solar Power

• The primary raw material in photovoltaic solar panel manufacture is crystalline silica. Silica dust produced in mining increases miners' chance of developing silicosis, lung cancer and other diseases. Other stages of manufacture expose workers to toxic chemicals such as highly volatile chlorosilanes and the eye and lung irritant silicon tetrachloride. Under the environmental laws of the US, Europe and Japan very little of these toxins are released into the environment, but the same cannot be said for facilities in China and India.

How is Solar Power reliable

• Solar power is unreliable. • Only 30% of sun power is collected from solar

items. • That is why solar powered calculators are very

hard to use.

How much of Canada’s energy comes from solar power and how much more CAN come?

• About 12,000 residential citizens have turned to solar power.

• By 2025, at least 5% of Canada should be using solar power.

Advantages and Disadvantages

The Disadvantages• If someone’s house

totally relies on solar power, that house will not have any light at night, and that is when you need it the most.

Advantages• An advantage is that it`s

good for the environment.

• It is a really cool source of energy.

• So far, no dangers from using the solar item itself has been found.

Vidoes of a Solar Power

Thank You!

• Thank you for listening and this the end of our science presentation.

• I hope you learned a lot about solar power and that you start using solar power in the future.
