Converts light directly to electricity Made of monocrystalline silicon Solar energy panel will produce 3,285 kWh in a year
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
Off-Grid Energy Large Scale Energy Production
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
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
Very little No emissions or waste product Harmful chemical used in small amounts, easily controlled through recycling
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
Can replace coal burning or nuclear power plants when used to create off-grid or large scale energy
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
