2. The Sun Celebrating 4.57 Billion Years! 5000 Celsius at Surface Average 1000 Watts/m 2 on Earth 900 Million Years to Go!

3. Harnessing the Energy:

4. Lighting

5. Electricity

6. Heating

7. Solar Water Heating/Cooking Effective way of harnessing energy Low startup cost Simple construction

8. Photovoltaics Use specific band-gap semiconductors Inverters/Batteries p material n material

9. Photovoltaics We will estimate the cost of a controller to be ~$200; various fuses/disconnects/ circuit breakers to be ~$80, wiring and terminations to be ~ $100, one 1000 watt inverter to be ~$300, one voltmeter to be ~$40. 3 solar panels @ ~$400 each = ~$1200. 2 L-16 batteries @ ~$250 each = ~$ 500. 1 – Controller/fuses/inverter/voltmeter = ~$ 720. TOTAL = ~$2,420.*
