What Do Solar Panels Cost?

We all want to know the answer to the questions: How much do solar panels cost? And is it really worth it? If someone showed up to your house today and said, “I have a free solar system that I am prepared to install at no inconvenience to you and all your bills will drop to zero,” you would likely take it without a second thought. Yet, because there has been so much discussion about what solar panels cost, you’ll need to give the idea some thought. Let’s look into some of the factors that make solar panel pricing so confusing.



Solar Photovoltaic Panels are measured in Watts & prices in Kilowatts.

This can be really confusing if A) you don’t know how many watts of power you use and B) you don’t know how many watts of power you need. There is no one-size-fits-all answer for this, since energy consumption depends upon your own personal usage. However, a good ball-park figure to run your whole house would be to plan on a 5 Kilowatt system. The average installation cost is about $7/Watt, so if you take $7 x 5,000 Watts, you get a total cost of $35,000. Don’t forget that you are eligible for solar rebates and a 30 percent federal solar tax credit on top of this cost.

It’s tempting to think of a solar panel investment in terms of immediate expenses, rather than down-the-road predictions spanning the product’s lifetime.

You need to consider how much money you’ll save in the long run. A system in solar states like New Jersey, Pennsylvania, Massachusetts, Colorado, California and Arizona would pay for itself in just three to five years. The long-term savings would be considerable. If your state offers rebates, you have a lot of sun in your area, and you would like your home value to go up, then a solar light system is a good investment.
