  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.

  7. 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.

  8. 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)

  9. 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

  10. 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

  11. Interesting fact!! • Solar panels are also called photovoltaic panels. "Photo" means light and "voltaic" means electricity.
