Try using a clothes line to dry your clothes. This is an older idea that works just as well. Rather than drying clothes in the dryer, hang them outside on nice days. This will save energy, which in turn will save money.
Check that your solar-energy installer has the proper licenses and insurance. Installing solar panels on a steep roof is a delicate job, and you should feel confident that your installers know what they are doing. At a minimum, look for a contracting license, workers compensation insurance, and general liability insurance.
Check into all of your potential rebates. You know there are rebates, correct? The government (in certain states) has a bunch of ways that they'll reward you for taking the solar energy plunge. And there are also benefits during tax season. Look into them all so you'll get every penny coming back to you.
