How Much Do Solar Panels Save?

Solar panels aren’t only good for the environment, they are good for
your wallet too! Over the lifetime of a solar panel system, customers
can see substantial savings, with the exact amount depending on your roof, usage, and local utility rates.

Savings vary based on factors such as location, usage trends, and the solar system you use. The most important savings factor is the price you pay for electricity.

How Much Do Solar Panels Save Per Month?

For most Rhode Island, Massachusetts, and Connecticut homeowners, solar panels offset a large share of the monthly electric bill, and in some cases eliminate it, depending on system size, roof exposure, and household usage. Your exact monthly savings depend on how much energy your system produces versus how much electricity you use, and on your utility’s net metering credit structure.

A properly sized system typically covers most or all of a household’s average monthly usage. Homes with higher electric bills, common across New England given some of the highest utility rates in the country, tend to see the largest monthly offset. Rooftop Power calculates your specific monthly estimate for free, based on your actual usage history and roof, rather than a generic average.

Points to Consider

• Solar panels can sometimes cost money upfront, however, in the long term you will save money on electric bills

•The higher the local electricity prices are the higher the potential
solar savings

•The average home can see meaningful savings with solar power, though the exact number depends on usage and local utility rates

Are Solar Panels a Good Investment for Most Homeowners?

For many homeowners, solar panels are absolutely a smart financial move. If your roof is in good condition and gets decent sunlight, going solar can mean impressive long-term returns.

Not only will you lower your electric bills and reduce your environmental impact, but you also open up the potential for significant additional savings. Depending on local incentives, like net metering, state rebates, you could see your solar savings grow substantially over the years.

And if your area’s electricity rates are high? You’re in an even better position. Some homeowners have reported saving tens of thousands of dollars (or more!) over the life of their solar system. With little downside and plenty of upside, solar is often seen as a low-risk, high-reward investment for households ready to make the switch.

Will Solar Really Save Me Money?

Yes! How much money you’ll save depends on several factors. The
amount of direct sunlight your system receives, the range, and the angle of your panels all play important roles in your savings. At Rooftop Power we have engineers and highly-trained solar design professionals to ensure your system produces the most it can for your home.

The most important factor in determining savings is the electricity
rates in your area. The more that electricity costs, the more that
you can offset it by producing more energy through your solar panels.

How to Find Out What Solar Panels Cost in Your Area

Curious about what solar panels really cost where you live? Getting accurate, up-to-date quotes is easier than you think, and it’s the smartest first step toward lowering your electric bills.

Typical Rate of Return for Solar Panels

The return on investment for solar panels is often much higher than what you’d expect from traditional financial options. In fact, according to the U.S. Department of Energy, your potential annual rate of return from going solar can easily outpace returns from many stocks, bonds, or savings accounts, often landing somewhere between 8% and 15%.

To put it in perspective:

• With high local electricity rates, your savings can make solar even more lucrative.
• Few mainstream investments, whether it’s the S&P 500 or a high-yield savings account, can consistently match the return you see from a quality solar setup on a suitable roof.

If your roof gets plenty of sun and your electricity rates are above average, solar panels often become one of the safest, strongest investments you can make for your home.

How Electricity Rates by State Impact Solar Panel Savings

When it comes to solar panel savings, where you live can truly make all the difference. One key reason? Electricity rates aren’t set in stone, they swing wildly from state to state. This means the value of your solar system goes up in areas with expensive electricity because every kilowatt-hour you generate is money you’re not handing over to the utility.

Why Rates Matter

Let’s break it down. Homeowners in California, for instance, pay some of the highest electricity rates in the country. So, every bit of energy those rooftop panels produce translates into bigger dollar savings compared to states with cheaper power. On the flip side, if you live somewhere like Washington, where rates are lower, the total savings will still add up, but not as dramatically.

State-by-State Differences

Here’s how this plays out:

• High-rate states (like California, Massachusetts, and New York): The higher your utility charges, the more you save by generating your own power. Over 25 years, homeowners in these states can see some of the highest solar savings in the country, thanks to steep rates that solar can offset.
• Moderate-rate states (think Arizona or Texas): Solar still works out as a solid investment, with more modest savings than the highest-rate states, over 25 years.
• Low-rate states (such as Washington): Savings are still worthwhile, but the impact is smaller because there’s less to offset in terms of electricity cost.

The Big Takeaway

No matter where you hang your hat, solar panels offer a way to shield yourself from rising utility bills. But if you’re living in a state where the cost per kilowatt-hour is high, your solar savings could be much greater over the life of your system. Local rates, system size, and how much sunlight your area gets all factor in, but when rates are up, your savings soar.

Maximizing Solar Savings in RI, MA, and CT

Let’s talk real numbers, because where you live makes a huge difference in how much you can save with solar.

Over the 25-year lifespan of a typical solar panel system (about the length of your warranty, though panels often last longer), the average U.S. homeowner can see substantial savings on electric bills. But here in Rhode Island, Massachusetts, and Connecticut, the math works out much better.

Why New England Homeowners See Some of the Biggest Savings

Our states may not have Arizona’s desert sunshine, but we make up for it with some of the highest electricity rates in the country, and that’s exactly why going solar here can be a financial game-changer.

• Massachusetts, Homeowners here often see some of the highest lifetime savings in the country, thanks to steep power rates and strong solar incentives.

• Rhode Island, Homeowners regularly see strong long-term savings over 25 years, with the added boost of state rebates and net metering programs that credit you for extra power you send to the grid.

• Connecticut, CT solar systems can deliver substantial lifetime savings, with the potential for even more as utility rates continue to climb.

How We Compare to Other States

• California: Some of the highest lifetime savings in the country (high rates + lots of sun)

• Arizona, Colorado, Texas: Solid savings over 25 years, more modest than the highest-rate states

• Florida, Washington: Worthwhile savings over the life of the system, smaller given lower local rates

Key Factors That Boost Your Savings in New England

1. Local electricity rates, Higher rates mean bigger savings on every kilowatt-hour you generate.

2. State + federal incentives, RI, MA, and CT offer some of the strongest rebate and credit programs in the U.S.

3. Roof sunlight exposure, Even in the Northeast, modern panels capture power efficiently in a variety of weather conditions.

4. System size & purchase method, Buying your system outright typically delivers the highest returns, while financing still locks in long-term savings.

Bottom line:
In Rhode Island, Massachusetts, and Connecticut, most homeowners see their solar investment pay for itself in just 6, 10 years, and then keep producing decades of clean, free power while utility rates keep climbing.

Will I Still Have An Electric Bill With Solar?

You will still have an electricity bill after installing a solar power
system. However, the bill may not require payment but rather show
how the usage was offset by net metering credits that month.

When you provide more electricity than you use these unused bill
credits roll over into the next month. Solar panels will lower the
monthly electric bill or in some cases eliminate it.
