How Much Will Solar Save on Your Xcel Energy Bill in Minnesota?

The first question most Minnesota homeowners ask about solar is: what does it cost? The second question, the one that actually determines whether solar makes financial sense, is: what will it save?

Those are not the same question, and the gap between them is where most solar decisions actually get made.

This guide walks through how solar savings work on an Xcel Energy account in Minnesota, what you can reasonably expect based on system size and usage, and where the numbers can go wrong.

How Solar Reduces Your Xcel Energy Bill

When your solar panels are generating electricity, that power goes directly to your home first. Whatever your home uses in that moment comes from the panels at zero cost from Xcel. You’re not drawing from the grid; the meter is essentially not running.

When your panels produce more than your home needs, typically on sunny midday hours, the excess goes back to the grid. Under Minnesota’s net metering rules (established under state law), Xcel credits you for that exported electricity at the retail rate. One kilowatt-hour out, one kilowatt-hour of credit in. 1:1.

This credit accumulates over the month. If you generate more than you use in a billing period, the credit carries forward. Over a full year, most well-sized systems in Minnesota generate enough to offset the majority of the homeowner’s annual electricity consumption.

The result: your Xcel bill drops, sometimes significantly. The degree of reduction depends on your system size relative to your consumption, your roof’s orientation and shading, and Xcel’s rate structure.

Understanding Your Xcel Rate

Xcel Energy’s residential electricity rate in Minnesota has increased over time and varies by tier and season. The general trend has been gradual rate increases, which is one reason solar’s long-term economics tend to improve the longer a system runs.

Your system doesn’t save you money at a fixed value per kWh, it saves you money at whatever the current retail rate is. As rates go up, the value of your solar production goes up with it. This is different from paying down a loan early, where the benefit is fixed.

One thing to understand about Xcel’s rate structure: the base service charge (a fixed monthly fee) does not disappear with solar. You remain connected to the grid and pay that charge regardless of how much solar you generate. For most homeowners, that’s a relatively small portion of the total bill, but it’s the floor, solar doesn’t eliminate the Xcel connection entirely.

How Much Can a Typical Minnesota Home Save?

Savings depend on three variables: your electricity usage, your system size, and solar production at your location.

A rough framework for typical situations:

Lower-usage home (8,000-10,000 kWh/year): A 6-8 kW system sized to that consumption will offset most of the annual usage. After installation, many homeowners in this range see annual Xcel electricity charges drop to the base service charge plus small balances in high-demand periods (winter months with short days and high heating loads, if they use electric heat).

Average-usage home (12,000-15,000 kWh/year): A well-sized 10-12 kW system covers the bulk of consumption. Higher usage homes sometimes still carry a modest Xcel bill in winter months when solar production is lower and consumption is higher. The annual net savings are typically still significant.

Higher-usage home or EV owner: Electric vehicles add meaningful load. Homeowners charging an EV can still achieve strong solar savings, but system sizing matters more, a system sized only for baseline home use will leave a lot of EV charging cost on the Xcel bill.

Important qualifier: these are illustrations, not guarantees. Actual production depends on your roof’s orientation (south-facing is optimal; east-west can work with the right system design), shading, and local weather patterns. Centauri uses Aurora Solar to model expected production for each specific home before any proposal is finalized.

Annual Usage	Typical System Size	Expected Annual Production	Offset Estimate
~9,000 kWh	6–7 kW	~7,200–8,400 kWh	80–95% of bill
~12,000 kWh	9–10 kW	~10,800–12,000 kWh	85–100% of bill
~15,000 kWh (+ EV)	12–14 kW	~14,400–16,800 kWh	90–100% of bill

Estimates based on south-facing roof, average MN solar irradiance, and minimal shading. Actual production varies. All figures rounded. Base service charge still applies.

Xcel Solar*Rewards: An Additional Savings Layer

For Xcel customers, the Solar*Rewards program can provide production-based incentives on top of the bill savings described above. The program pays qualifying homeowners for each kWh their system produces, separate from the net metering credit for exported power.

Solar*Rewards rates change as program capacity is consumed and new program phases open. The most current rates are always on Xcel’s Solar*Rewards page : never rely on a number quoted in a sales presentation without verifying it there.

Centauri’s team checks Solar*Rewards availability and current rates as part of every proposal process.

Connecting Solar Savings to Financing

One of the most useful ways to think about solar savings is to compare them to your financing cost, if you’re financing the installation.

If your monthly solar loan payment is, say, $180 and your Xcel bill drops by $150 per month, you’re spending $30 more per month than before, but you’re building equity in a home asset, locking in an energy cost, and your Xcel savings grow as rates increase while your loan payment stays fixed.

As the loan pays off, the full monthly savings go to your pocket. For most homeowners, the break-even on a financed solar installation in Minnesota is in the range of 7 to 12 years, after which the system continues to produce free electricity for another 15+ years.

FAQ

How much can solar reduce my Xcel Energy bill in Minnesota?
For a well-sized system on a home with average consumption, annual Xcel bill reductions of 80-100% are achievable. The base service charge (a fixed monthly fee) remains regardless of solar production.

Does Minnesota have 1:1 net metering with Xcel?
Yes. Minnesota state law requires utilities including Xcel to credit solar customers at the retail rate for exported electricity. One kWh exported earns one kWh of bill credit.

Does the Xcel Solar*Rewards program still apply in 2026?
The Solar*Rewards program is active for Xcel customers in Minnesota. Rates and availability change as program tiers fill. Always verify current rates at co.my.xcelenergy.com/s/renewable/solar-rewards.

Does solar eliminate my Xcel bill entirely?
For most homeowners, solar significantly reduces the Xcel bill. The base service charge remains since you stay connected to the grid. In high-consumption winter months, some usage may still come from the grid. Complete elimination of the Xcel bill is possible for some lower-usage homes with larger systems.

How does an EV affect solar savings in Minnesota?
An EV adds significant load but also makes a larger solar system more cost-effective. Homeowners who own or plan to own an EV should size their system for the combined home and vehicle load to maximize savings.
