For many homeowners investing in solar panels makes sound economic sense.  Not only will they receive a handsome credit on their federal income tax, but their home value increases, the environment is improved, and their energy dollars are reduced.

However, purchasing a solar panel system for your home is a major investment.  And like any investment, should be thoroughly researched before expending the money.  Here are some things to consider before your purchase.

• How much energy do you need to produce? Call a local solar contractor for an energy estimate or use one of the many estimators online.
• What type of mounting system will use?  Usually they come in two varieties.  One is called the proper tilt mounting which mounts the panels a specific angle to get the most use of the sun. The other mounting system is called a solar tracking mount which will adjust the panels to follow the sun.
• What type of solar panel is best for your need?  There are two basic types of solar panels: crystalline silicon panels and amorphous silicon panels.  The amorphous panels are a good choice if you have a large space; while the crystalline panels are better for smaller spaces.
• Will the payback period exceed the life of solar panels? Typically solar panels have a 25-year warranty and if properly installed will last 20 to 40 years.

Once you’ve done the research get bids from several contractors and check their references thoroughly before hiring. Finally check to see if there are state energy credits for installing solar panels.
