SOLAR CELLS
Converts light directly to electricity Made of monocrystalline silicon Solar energy panel will produce 3,285
kWh in a year

PHOTOVOLTAIC EFFECT
Creation of electric current in a material on exposure to light (silicon)
Electrons are transferred between different bands within the material, resulting in the buildup of voltage between two electrodes

USAGE
Off-Grid Energy
Large Scale Energy Production
![Page 6: Brendan Bossidy. Converts light directly to electricity Made of monocrystalline silicon Solar energy panel will produce 3,285 kWh in a year](https://reader036.vdocuments.net/reader036/viewer/2022062404/551aaccf550346856e8b4c1f/html5/thumbnails/6.jpg)
ADVANTAGES
Sunshine is only fuel, renewable and local resource
No waste product, no emissions Quiet and unobtrusive systems Can utilize empty space on roofs Low maintenance Can be constructed to fit any needs Low environmental impact, chemical
easily controlled

DISADVANTAGES
Toxic chemicals such as cadmium and arsenic used in process, minor usage and impact
High cost to manufacture a PV device Variable energy source, dependent on
the sun Requires batteries to store energy,
batteries must be changed periodically over years

ENVIRONMENTAL IMPACT
Very little No emissions or waste product Harmful chemical used in small
amounts, easily controlled through recycling

USAGE
Produced and used in year round sunny countries such as California, United States sun belt, and the Mid West
Used in developed countries around the globe that intake a lot of yearly sunlight (Japan, China, Germany)
Little market in developing countries, very expensive now but hope for future

PERFORMANCE
In US, $2.43/watt , well below nuclear power
Large scale is $1.00/watt Low maintenance once constructed Last for several years without battery
change, panels last for longer $5,500 to $22,500 for 0.5kW - 3kW
residential PV systems initial cost
