Solar PowerBy: Ashton Mitzel
History 1876 founded that when selenium is
exposed to light it creates electricity, without using any heat or movement
1953, silicon solar cell was discovered Produced enough electricity to power a
small electrical device
1950-1960 Satellites in the USA’s space programs
began to be powered by solar power Soon became standard for powering all
space satellites
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
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.
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.
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)
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
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
INTERESTING FACT!!
Solar panels are also called photovoltaic panels. "Photo" means light and "voltaic" means electricity.
