They are electrically efficient.  They are less expensive.  They are flexible.  They are environment friendly.  
their advantages are not well-recognized.  they do not work well if exposed to light.  they need improving in appearance.  they are not advertised.  
creating electricity.  cooling silicon solar cells.  generating heat.  powering solar thermal collectors.  
Now, there is a good environment for the private sector to grow in producing solar power generated energy.  There are encouraging measures that the government takes to propel the solar industry development.  There are some reasons why the utilities are not interested in rooftop solar system.  The advantages and disadvantages of making use of rooftop solar system.  
In 2008, the amount of rooftop solar system installment experienced an increase over 50 percent.  95 percent of Californian families have rooftop solar system installment.  More and more families installed rooftop solar system installment as a way to cut expense on electricity.  There is no positive connection between economical situation and the amount of rooftop solar system installment.
