Solar photovoltaic and solar thermal systems are gaining in popularity, especially in the South West United States where, according to SolarBuzz.Com, growth rates for new solar system installations by 2014 will increase by as much as 10 times that of the market size in 2009. One would think that with such phenomenal growth rates, more home manufacturers, factor built builders especially, would add solar pv and solar thermal systems as standard options.
So why don't more manufacturers do this since the solar market seems to be taking off? The answer lies primarily in the development cost of associated with providing new options of any kind to consumers. Developing new home options that require complex engineering plans and designs is not cheap. A home builder that want to add energy efficiency options in to the mix of what they offer consumers can look at having to bankroll a development project for years before they may see any real return on investment. This, primarily, is the reason most installations of solar systems happen on existing homes and not be developers themselves.
