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.
You should never feel pressured to buy something, especially an expensive solar energy system. These types of salespeople are pretty common in this industry. You can tell them you'll be back later, and they should be fine with it. If they are persistent about making a deal now, tell them that the deal should be just as good in the future. Making decisions under pressure can be more costly later on.

Do not rush in selecting the first solar power system you come across. Before you make a commitment with a company, you need to make sure you cannot find any better deals elsewhere. Check out your town's federal, state, and local incentives first. You can find this information at the DSIRE database.
