What are some of the environmental savings associated with the installation of a solar photovoltaic system?

The annual emission offset for a 4 kW system is:

• 4 pounds of oxides of nitrogen
• 18,000 pounds of carbon dioxide
• This is the equivalent of driving your car 22,600 miles per year
• The carbon dioxide absorbed by 2 acres of trees.

As you can see, the environmental savings, when added to the obvious monetary savings, makes solar photovoltaic systems a good investment for the homeowner and society.
