1. Solar Power By: Ashton Mitzel

2. History  1876  founded that when selenium is exposed to light it creates electricity, without using any heat or movement

3.  1953, silicon solar cell was discovered  Produced enough electricity to power a small electrical device

4.  1950-1960  Satellites in the USA’s space programs began to be powered by solar power  Soon became standard for powering all space satellites

5.  1970  Discovered a way to decrease the price on solar power increasing the amount of people to use this method  Today we see many things powered by solar power such as cars, aircrafts, and many more

6. How does it work?  When sunlight hits the silicon panels, cause electrons to move around  Electrons the flow through wires converting the sunlight into electricity  With the power generating you can pretty much do anything you want with it.

8. Pros No pollution produces electricity very quietly ability to harness electricity in remote Very efficient eliminates the problem of finding the required space, can be placed on any rooftop The cost, once installed provides a free source of electricity, less dependent on the worlds fossil fuel supplies.

9. Cons initial installation of solar panels very costly only able to generate electricity during daylight hours. weather can affect the efficiency of solar cells. as pollution levels can affect a solar cells efficiency, effecting businesses that want to install solar panels in heavily polluted areas(cities)

10. Examples in B.C. Use of solar power modules in BC is at sites that have no access to grid power, such as some radio repeater stations, remote monitoring stations, and some homes Since you are allowed to install solar power panels on you house or businesses

11. How much does it coast? installed solar powers in BC costs around $3 per watt or $15,000 for a 3kW system The installation of the solar powers is the expensive part as the electricity is from the sun so therefore its practically free

12.  Solar panels are also called photovoltaic panels. "Photo" means light and "voltaic" means electricity.
