First Slide

2. Simply, it is...
Brief Knowledge about solar energy
contracting the sunlight into usable electricity power by using photovoltaics or indirectly using the concentrated power into energy by applying the reflection of light.

4. Short History of Solar Energy
In William Grylls Adams discovered selenium
In Calvin Fuller, Gerald Pearson, and Daryl Chapin created silicon solar cell
Brief History of Solar Energy

5. How it Works 1) Photovoltaic cell
--> conducts sunlight's radiation into the silicon photo-electric cell and transfers the stored radiation to electricity
2) Concentrating Sunlight
--> focuses the sunlight directly into a conducting wire w/ lenses
The detailed steps of solar energy is produced

9. Advantage VS Disadvantage
NO GREENHOUSE GASES EMITTED
LIMITED WITH TIME
VERY EFFECTIVE IF UTILIZED WELL
EXPENSIVE COST
STORE GREAT AMOUNT OF ELECTRICITY
POSSIBLE POLLUTION BY CADMIUM
LOCATIONS ARE ABUNDANT
LACK OF SOURCE

11. Conclusion SOLAR ENERGY...
1. uses photovoltaic cells to capture sunlight radiation or uses lenses to focus light rays into one spot
2. is useful in many ways because of its ability for storing electricity and it doesn't produce greenhouse gases
3. may pollute ecosystem because of cadmium and its practicality is questionable
