SOLAR FACTS

The Amount of Sunlight We Receive in 1 Hour is Enough to Power the World for a Year

That’s 122 PetaWattsOR

122,000,000,000,000 KWHs

SOLAR FACTS

1300 Watts of Solar Energy per Square Meter Impact the Upper Atmosphere

By the Time that Solar Energy Reaches the Ground 300 Watts have been Lost Through Absorption or Reflection by Particles in the Air

That’s Gives Us 1000 Watts / Sq Meter to Create Clean Energy

SOLAR HISTORY NASA Uses Solar Film Panels for Powering Satellites

SOLAR HISTORY – OFF-GRID Earlier Solar was Mostly Used for Off-

Grid Applications

Solar System is Not Connected to the Electric Grid

SOLAR HISTORY – ON-GRID Now Most Solar Systems Installed

Are Grid-Tied

Solar System Is Connected to the Electric Grid

SOLAR PHOTOVOLTAIC (PV) VS SOLAR THERMAL

Solar PV Generates Electricity Solar Thermal Utilizes the Suns Heating

Properties to Heat a Liquid Hot-water Heater Pool Heating Radiant Floor Systems

WHERE SOLAR WORKS

Germany is the Largest Installed PV Country in the World 40% of Their Energy Comes from Solar Feed-In-Tariff or FIT

Only place in U.S. with this type of program is Gainesville, FL

More Communities in the U.S. are Considering a FIT

WHERE SOLAR WORKS

WHERE SOLAR WORKS

National Renewable Energy Laboratory (NREL) Mapped the United States for Solar

Radiation Tampa Bay Area Insolation is 5.4 Which is

Only 13 % Less Than U.S. Peaks and Provides Excellent Energy Production

U.S. Solar Peak Radiation is Located in the Desert Area of Southwest United States

WHERE SOLAR WORKS

HOW DOES SOLAR PV WORK?

Photoelectric Effect The photoelectric effect is a

phenomenon in which electrons are emitted from matter (metals and non-metallic solids, liquids, or gases) after the absorption of energy from electromagnetic radiation such as X-rays or visible light.[1]

Visible Light is Made Up of Photons They Carry Enough Energy to Cause an

Electrical Current to FlowSerway, Raymond A. (1990). Physics for Scientists & Engineers. Saunders. pp. 1150. ISBN 0030302587. http://books.google.com/books?id=RUMBw3hR7aoC&q=inauthor:serway+photoelectric&dq=inauthor:serway+photoelectric&pgis=1. Describes the photoelectric effect as the "emission of photoelectrons from matter", and describes the original usage as the "emission of photoelectrons from metallic surfaces" after the experiments of Milikan, and others.

SOLAR PANEL MANUFACTURING PROCESS

Two Biggest Countries Manufacturing Solar Panels are Germany and Japan

We Start with Silicon Not Silicone – It has Other Uses

Like Sealing Up a Leaky Bathtub Or Certain Personal Image Improvement

Enhancements

GOD BLESS AMERICA


Start with Silica Sand Most Abundant Mineral in the Earth’s Crust


Mono-Crystalline Most Efficient – as high as 22% Single Seed Crystal Used to Form Entire Ingot

Poly-Crystalline High Level Efficiency – 15-18% Slightly Less Expensive than Mono

Thin Film Least Efficient – 6-10% Cheapest to Manufacture Uses Ink Printing Method


Chemical Process to Purify Into High-Grade Silicon

Silicon is Then Heated and Molded Into a Silicon Ingot

Silicon Ingot is Then Cut by Diamond Saw or Laser Into Silicon Wafer


Wafer is then Transformed into a Solar Cell by Chemical Processing and Addition of Electrical Contacts


Solar Cells are then Assembled Together to Form a Solar Panel
