Solar panels are not very easy to install, so you should hire a professional to get the job done. While you will save a bit of money by trying to do it in your own, you do not want things to be less than perfect. Also, you will most likely end up paying someone to come out and fix the mess you made.

Remember that solar energy can do more than just power your lights. They can provide heat and warm up your water, too. Solar panels can make a significant impact in your overall energy bill. You don't want to be overpaying the power company.
Always look for a good and qualified contractor to install your solar system. Just because you are having a new technology installed on your home, does not mean that you should look for new contractors. The type of work is very specialized and having a quality contractor with a proven track record is critical to having your system installed properly
