1. Solar Array
Provide the energy needed to power the theatre with solar and wind power
LEDs need less energy therefore it is more cost effective to use solar panels
plan on providing 70% of the energy used through solar cells

2. Electricity Flow of electrons Current-measure of flow (in Amps)
Voltage- work/charge
Power= volts X amps

3. Silicon Silicon is a semi-conductor
Silicon forms a very stable crystalline structure
Must be “doped” to form solar cells
Boron and Phosphorous

4. P-N type
P-type silicon is positive type, doped with boron (one less electron)
N-type silicon is negative type, doped with phosphorus (one more electron)

5. How It Works Layers of P and N type silicon
Photons are absorbed by semi-conductors
Electrons are “knocked loose” from their atoms and move through the solar cell

6. Silicon Solar Cells
Two basic types
Mono-crystalline
Poly-crystalline
