Be aware that you can still get solar power benefits even if you live in a chilly, overcast area. It doesn't need to be like Florida all year round for it to be a big part of your energy savings goals. Great solar power output can come on poor weather days.
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.
When switching over to solar panel, take the time to evaluate all of your energy needs. Solar panels are far from cheap, and there might be more cost effective ways that you can reduce energy consumption in your home. By reducing consumption, you can reduce how many panels you need, thereby reducing your overall purchase and install costs for a solar system.
