If you enter your zip code into the solar power calculator below you can find out how many solar panels you need for your home and see live current solar prices in your city for that size of solar system. This is the easiest way to cut to the chase because when it comes to solar panel cost knowing the average cost of solar panels (as we display in the tables on this page) doesn't really help you determine solar panel cost you would face to power your home with solar energy. Your home will be different to any other home and so solar panel cost is likely to be different to the average solar cost data.

How our solar panel cost calculator calculates how much solar panels will cost for your house in Massachusetts?
Whilst it is great to have a ballpark average solar panel cost (see tables above) as a starting point, or even individual current solar offers from solar companies near you this doesn't help you if you don't know how many solar panels you need, how many square feet of usable roof space you have or how the electricity production from your roof may differ from the perfect roof.
The best way to get this information is to request a solar quote from one or more solar companies. However, for those that want to get a reasonably accurate online solar estimate before speaking to a solar company the Solar-Estimate.org solar power calculator has you covered.
The solar panel calculator estimates a system size while only requiring you to enter your address and power spend. It is not as accurate as if you uploaded a series of monthly power bills but it is a good place to start because it requires little effort. If you want to go further it will show live current solar offers in your area and then have one or more local solar companies provide accurate quotes if you validate your contact information.
Generally speaking, the aim of a solar panel installation is to install a solar power system that will produce the same amount of electricity that your home uses. This is because net metering laws limit the size of eligible solar systems to a system producing a similar amount of energy as your house uses.
This is why the solar calculator suggests a size of system that produces the same amount of electricity as what the software calculates you use, based on your monthly power bill. Because the calculator has a database of the electricity rates of your utility it can reverse engineer your usage from the amount you pay.
