We get asked, “How much do solar panels save?” every day. While yes, you will either greatly reduce or eliminate your electric bill, determining your total solar savings is influenced by several other factors, including how you finance your solar system; whether you take advantage of tax incentives such as the 30 percent federal investment tax credit; how much you currently pay for electricity and whether you plan to sell your home.
In general, the more photovoltaic (PV) solar energy you produce, the less electricity you have to buy from your utility company. That means your solar savings start as soon as your solar system is activated.
The easiest way to estimate your electric bill savings is to enter your home address into our online solar savings calculator. The next step is to call 1-800-SunPower to get some more details. An energy consultant will help you determine whether your average electricity bill is high enough warrant the switch to solar ($75+ a month). Then, you can begin to find out: is my home is right for solar? For example, can you generate enough solar energy for your family’s needs, do you have excessive shading on your roof and does your local utility have solar-friendly policies?
How Much do Solar Panels Save?
Most people going solar want to know how much solar panels can save on electricity bills. But there are other financial benefits that determine how much solar really saves. Solar can help you:
Protect yourself against electricity rate hikes. Easily the biggest reason people go solar is to reduce their energy bill. A typical American family spent about $1,335 on electricity alone in 2018, and national electricity costs typically rise at a rate of about 2.2% per year. In some areas, energy prices spike sharply based on the weather or demand on the energy grid at certain times of day so going solar can allow you to lock in a set energy price. So how much will solar panels save you per year? While it varies by customer and time of year, many of our customers say they no longer have an electricity bill or pay just a nominal connection fee each month. (Read about a New Jersey homeowner with a $4.53 monthly bill.)Increase your home value. By reducing or eliminating your electric bill, adding a solar panel system is almost always a good real estate investment. According to a recent Zillow analysis, depending upon where you live, solar can increase home values by 4 percent.Take advantage of federal tax credits. The federal solar tax credit, also known as the solar investment tax credit (ITC), allows homeowners who have their solar system installed by the end of this year to deduct 30 percent of the cost of their solar purchase from their federal taxes.1 The credit is set to scale down to 26 percent in 2020 and 22 percent in 2021. If your tax bill isn't big enough in one year to accommodate the credit, it can be rolled over to the next year for as long as the credit is available.
SunPower New Jersey customer Paul Devoy was spending $2,200 a year on electricity. After he went solar he often had just a $2.83 monthly service fee. He points out: What other home investment actually pays you money? A kitchen remodel? No.
“You tell me an investment that you can do that actually is going to pay you money,” Devoy said. “(With a solar system) I can calculate exactly what I’m getting back.”
He’s so satisfied, in fact, that he’s now putting a SunPower system on his new home.
