Solar Energy Advantages and Disadvantages
   As oil prices spike, people are looking for alternative energy sources to save money. Here are solar energy advantages and disadvantages, with advantages definitely winning out.

   Solar energy can be defined rather simply as the conversion of sunlight into usable energy. Currently, solar energy is used to provide electricity to homes, businesses, schools, universities and space vehicles used by NASA. As traditional energy prices rise, solar energy use is growing at a rate of 25 percent a year.

Solar Energy Advantages
  * The power source of the sun is absolutely free.
  * The production of solar energy produces no pollution.
  * The technological advancements in solar energy systems have made them extremely cost effective.
  * Most systems do not require any maintenance during their lifespan, which means you never have to put money into them.
  * Most systems have a life span of 30 to 40 years.
  * Most systems carry a full warranty for 20 to 30 years or more.
  * Unlike traditional monstrous panel systems, many modern systems are sleeker such as Uni-Solar rolls that lay directly on the roof like regular roofing materials.
  * In 35 states, solar energy can be fed back to the utilities to eliminate the need for a storage system as well as eliminating or dramatically reducing your electric bills.
