Solar Energy! Ibrahim Togans
The Great Sun Power • Solar Energy is a renewable resource. The way Solar Panels work is that it takes the photons from the sun and puts it into the photovoltaic, then the photovoltaic turns the photons into electrons, then the electrons flow into the house.
Advantages • An advantage of Solar Panels are that it saves much energy with energy bills. • Also helps the environment by not using gas or coal as an energy source. • It is a green energy source.
Disadvantages • A disadvantage is that it does not work at night. • Solar panels can be VERY expensive. • If a day happens to be overcast, you don’t have power. • Storing the energy has to be implemented and is sometimes difficult to do.
Britain's first solar panel uncovered after 60 years... and it still works Read more: http://www.dailymail.co.uk/sciencetech/article-1264487/Worlds-solar-panel-uncovered-60-years--works.html#ixzz1pu9kx7Nr
History • During the 1970s, there appeared to be oil shortfalls after the 1973 oil embargo struck. • The shortfall in oil, caused an alternative method to be produced that would allow other types of energy sources to be used as a replacement for oil. • Government made some investments and changes to solve this problem. • They allocated $400 million per year for solar energy research.
History • The first ever solar panel has been uncovered after being hidden away forgotten in a box for 60 years - and incredibly, it STILL works.
History-The First Solar Panel • The amazing contraption is the brainchild of a British science teacher who wanted to prove to his friends that it was possible to turn sunlight into electricity. • In 1950 he spent hours slaving in his laboratory to complete his cell based on the junction semiconductor idea patented in 1946 by Russell Ohl. • Read more: http://www.dailymail.co.uk/sciencetech/article-1264487/Worlds-solar-panel-uncovered-60-years--works.html#ixzz1pu8sF1h5
How much are solar panels used today? • In most rural places in the developing world there is no electrical supply at night to light up homes, streets, schools and hospital. • Children cannot see to learn and adults cannot be productive. • Solar power can also be used to run other pieces of equipment such as computers and refrigerators. Residential • The number of PV installations on buildings connected to the electricity grid has grown in recent years. • Government subsidy programs (particularly in Germany and Japan) and green pricing policies of utilities or electricity service providers have stimulated demand.
How much are solar panels used today? Cont’d • Holiday or vacation homes without access to the electricity grid can use solar systems more cost-effectively than if the grid was extended to reach the location. • Calculators • The use of solar panels keeps growing.
