Finding a reputable contractor who understands solar panel installation is very important to the quality of your solar power system. As with any work on your home, you should be certain to check the references of any contractor you are considering using to install solar panels at your home.
Before you hire a contractor, you should also be aware of local building codes, zoning ordinances as well as what your homeowner's association (if applicable) has to say about intalling solar panels. In most cases you will need a permit.
How well your solar power system is installed will have an impact on how well it works for you, so it is vital that you select a contractor with solid experience in installing solar panels. The contractor will need to design your system to meet local codes as well as your needs.
Make sure you get competitive bids from at least a few contractors. You can do a search online for contractors in your area or use your Yellow Pages. You will want to know what your budget is as well as your timeframe.
