A Few Solar Energy Facts
0 Comments
- Average solar panel prices are down to $1.34 per watt from $4 per watt in 2008
- In the United States, from 2009 – 2010, solar power installations increased by 102 percent
- In 2010 there was reported 18.2 gigawatts (GW) of solar energy installations across the globe
- 2010 saw an increase in solar energy installations globally of 139% compared to 2009
- Japan, Italy, Czech Republic, Germany, and the United States are the top five countries with demand for solar power, which represents about 80% of the solar energy demand market
- 2010 saw over a 100% increase in solar cell manufacturing compared to 2009, from 9.86 GW up to 20.5 GW
- Germany, which now gets approximately 17% of its energy needs from solar energy, installed 7400 megawatts(MW) in 2010, which set a new world record
- The United States exceeded 50 Giga-Watts of renewable energy electricity supply in 2010
- There was a 67% increase in the solar industry from 2009 to 2010 in the United States
- Grid connected photovoltaic energy is the fastest growing energy source in the world. In 2007 there was 15 Gigawatts of solar generated electricity available from solar power.
- Sunlight is made up of different types of energy across the energy spectrum, which the majority is Infrared, Visible and Ultraviolet.
- Solar energy can be used for more than just creating electricity, such as for heating, cooling and lighting.

- Solar panels output Direct Current and in most applications needs to be converted to Alternating Current to power the most common household appliances.
- About 200,000 homes in the United States use solar energy power for some of their energy needs.
- Current solar panel technology, for residential applications are only about 15% efficient.
- An inverter is used to convert solar panel output of direct current to alternating current.
- Solar panel efficiency is increasing while solar panel cost is decreasing as this continues solar power energy will increase.
- Multi-layer solar panels will increase solar panel efficiency by capturing more wavelengths of the sun’s solar output
- Out of the many emerging newest emerging sources of energy, solar is one of the fastest growing.
- Another of the few facts, solar energy is the most recognized renewable energy source with the exception of perhaps wind power.
- As I find more solar power facts and solar facts I will add them to this list
- This site will continue growing with more solar energy information
