Solar Energy
Step 1:
Solar Rays To Panels
Step 2:
Solar Panels To Batteries

Step 3:
Batteries To Our Electronics
Circle Of Solar Energy
By:Gabrial,Ethan and Lucas
How Solar energy works?
Solar energy requires energy coming from the sun (sun light).
The light from the sun goes in the solar panels.
The solar panels are made out of photovoltaic (PV) cells which converts sunlight into a direct current (electricity). This electricity goes in to batteries.
So when that electricity is needed it is sent out of the batteries and sent here needed.
The photovoltaic modules or batteries store energy that is harvested by the Solar rays and is waiting to be used.
Solar energy creates electricity. That electricity fuels all your electronics and lights in your house.
Solar energy creates electricity trough solar panels which fuels your electronics efficiently and without provoking more pollution.
With use of the Solar Energy you can save energy in your battery in case of a storm or a power outage.
History and Background of this energy source
Is Solar Energy a renewable energy source?
What technology is involved with Solar energy source?
What percent of the World's and Canada's Energy is supplied by solar energy?
The next step of obtaining solar energy is transferring the solar energy obtained by the solar panels into the batteries.
The first idea for Solar energy was in 4th century Greece when they used concentrated sun rays to light fires.
This as the first idea of Solar Thermal (heat) energy.
In 1839 a man named Alexandre Edmond Becquerel discovered that photovoltaic cells can either reflect, absorb or let the photons in sunlight pass. This was the first step in the modern solar panel creation process.
Later in 1876 William Grylls Adams and his student Richard Evans Day discovered that the element Selenium creates energy when it comes in contact with sunlight.
With the joining of Photovoltaic cells and Selenium along with some other basic materials solar panels can be created.
Raw Selenium
Alexandre Edmond Becquerel
Photovoltaic cells are permeable to photons from sunlight.
Selenium transforms these photons into electricity
With the Photovoltaic cells on the outside of the solar panel and the Selenium on the inside Photons are able to go through the cells and through the Selenium to become Electricity.
The electricity travels along wires into batteries for storage.
The power is then taken out of the batteries for immediate usage or kept stored until it is needed.
A solar battery
Solar energy is a renewable energy source
The energy is harvested from the sun.
In theory the sun will never die out so this energy can be harvested forever.
Unlike fossil fuels which are non-infinite
However the sun CAN technically turn into a Red Giant in 4-5 billion years but this is an exception
This energy source is very good for the environment as it does not pollute at all.
A Red Giant
How efficient and cost effective is this energy source?
Where in Canada is this energy source used?
Solar energy is rather efficient as it does not cost much and does not pollute the Earth.
Solar energy does not take too much roof or ground space to supply decent energy.
There are advantages and disadvantages the cost effectiveness of Solar energy.
At first solar panels are expensive with prices ranging in the hundreds to thousands
After the cost of the panels is payed off solar panels can save you up to 75% of your electricity bill.
Solar Energy
This energy source is used all over Canada but it is primarily used in southern British Columbia, Ontario, Quebec and the Prairies
Most of this energy is privately used (it is on individual houses)
Note: The numbers are kilowatts per hour.
Are there are harmful or beneficial effects on the environment?
There are absolutely no harmful effects on the environment.
The benefits of this energy source are that:
It does not pollute
It is good for the environment.
Less than 5% of the world uses solar energy
Most of the world is composed of developing countries
They are too poor
They have none or almost no access to companies
Not as practical as fossil fuels (fossil fuels are easier to use)
Many people fail to understand that it is extremely cost efficient and good for the environment.
The developing countries (the darker color the poorer the country is)
Are there any benefits or liabilities for this source?
The benefits for this energy source are that:
It is cost efficient (after initial investment is paid off)
The liabilities are that the initial cost can be large.
Solar panels
require lots of maintenance. (depending on weather, i.e hail)
People do not consider solar energy as it does not appear as an idea because it is relatively new in modern day life.
How would you describe the future possibilities for this energy source?
What political, moral, ethical dilemmas do we face?
Eventually the world
run on this renewable energy source.
as it is a great way to save money and the environment
With future tech being added into Solar Panels its a large possibility and the solar energy consumption can go up to 5% in 2025.

Solar energy is a long lasting eco friendly fuel.
Politicians can make a lot of money for charging people the same amount for electricity even if it cost for politicians is less to creates electricity.
