Solar panels aren't suitable for every house.
So the first thing you should do is find out if your roof gets enough sun throughout the day.
The easiest way to check your home for solar viability is by typing your address into Google's Project Sunroof website.
The tool will let you know how many hours of sun your house gets per year and how much money you would save by switching to solar.
Google sun roof is only available in some areas.
So if your house isn't in one of them you'll need to do the leg work yourself.
An easy way to get a good estimate is by finding your location on Solar maps provided by the National Renewable Energy Laboratory.
If your home is in an area of the country that receives very little sun, you may not be able to go solar.
From that point, you'll need to do some math to find out if going solar will save you money.
