Solar Power Presentation
Transcript of Solar Power Presentation
The amount of energy the world uses from the sun is about a total of 3,850,000 exajoules per year.
What is Solar Power?
Energy taken from the sun
Coverted into heat or electricity
Solar energy can be converted in two ways
Photoelectric applications (solar panels)
Where Does it Come from? How is it recovered?
Comes from the sun
Travels from the sun to the Earth in waves or rays.
It is recovered by Photovoltaic Cells/ Solar Panels or Solar Thermal Technology
Amount of energy that comes to the Earth is not constant.
Dependent on location, time of day/year, and weather conditions
The cost of the solar panel and installation is expensive.
Mechanic/Motion in Solar Energy
1) The sun
2) Solar panels
3) Electric current
4) Changes controller
5) Battery sytem/Inverter
How is it used in the CT?
Connecticut residents pay more for electricity than just about anyone else in the continental U.S. In some cases, a moderately sized system (6000watts) can cut a family’s electricity costs by up to 80% or more.
Bridgeport's Future In Energy

Photovoltaic Cells/ Solar Panels
A group of Photovoltaic Cells is called a Solar Panel
It will be used on a daily basis
We'll not only use solar panels on houses, but also on cars and new inventions.
There will be more solar panels.
Solar Thermal Technology
How it works?
1)Mirrors reflect the sun's ray to heat a liquid
2) The heat from the liquid boils water which then creates steam
3) Steam then spins the turbine that's connected to a generator to create electricity.
4) After liquid cools the process starts over again!
1) Sunlight hits the surface of the Photovoltaic cell.
2) The Sunlight is then absorbed to be converted into electricity by the semi-conductor
How it works?
Is Solar Power Right for Bridgeport?
How much is used in the United States?
In the twelve months through July 2013, solar power generated 6.4 million megawatt-hours, 0.16% of total US electricity.

Wise Geek- Whst is solar power? (http://www.wisegeek.org/what-is-solar-power.htm)
Sunlight is free
Sunlight will not run out
I think that Solar Energy is not right for Bridgeport.
It takes a lot of solar panels to create a good amount of energy
Solar panels cost a lot of money
Weather is not always that great because of the water
