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.
If you're trying to design your new house, think about putting in a bunch of big windows on the home's south side so that during the winter you can get a lot of sun. Make sure you have methods in place to keep excess heat out during the warmer summer months. For more help, consult a contractor who specializes in solar energy.
