Get quotes from several contractors before signing any solar energy installation company. Just as with any other construction product, it pays to shop around before you commit to a particular company. Check out their reviews online and their standing with the Better Business Bureau. A little research ahead of time can save you a big headache later.
I have been thinking about getting solar panels for a little while now, my uncle has has a small install for about 10 years, and my mate Ed recently had an install.
