Buying Delivers More Value, but Leasing Has Its Place

When you go solar, the first decision after choosing an installer is how you’re going to pay for the system. The two main options are buying the panels outright, either with cash or a solar loan, or leasing them through a solar lease or power purchase agreement. Both options reduce your electric bill from day one, but they work very differently in terms of ownership, savings, tax benefits, and what happens when you sell the home.

For most homeowners who can afford the upfront cost or qualify for financing, buying is the better long-term financial decision. But leasing exists for a reason, and it can be the right choice in specific situations where ownership isn’t practical. Here’s how the two paths compare.

How Buying Works

When you buy your solar panels, you own the system. You pay the full cost upfront with cash, or you finance it through a solar loan and make monthly payments until the loan is paid off. Once the system is paid for, the electricity it produces is essentially free for the remaining life of the panels, which is typically twenty-five to thirty-five years.

The U.S. Department of Energy’s homeowner’s guide to solar notes that owning your solar system gives you the greatest financial benefit over time. As the owner, you’re eligible for the federal solar tax credit, any state or local incentives, and the full value of the energy the system produces. You also own an asset that adds value to your home if you decide to sell.

The main barrier to buying is the upfront cost. A typical residential solar system costs fifteen thousand to twenty-five thousand dollars before incentives. After the federal tax credit and any state-level incentives, the net cost drops significantly, but it’s still a meaningful investment. Solar loans make the upfront cost manageable by spreading it over ten to twenty years, and many homeowners find that their monthly loan payment is less than what they were paying the utility company.

How Leasing Works

When you lease solar panels, a third-party company owns the system and installs it on your roof. You pay a fixed monthly fee to use the electricity the panels produce. In a power purchase agreement, which works similarly, you pay a per-kilowatt-hour rate for the electricity rather than a flat monthly fee. Either way, you don’t own the panels, you don’t maintain them, and you don’t receive the tax credits or incentives associated with the system.

The appeal of leasing is that there’s no upfront cost and no loan to qualify for. The solar company handles the installation, monitoring, and maintenance for the duration of the lease, which typically runs twenty to twenty-five years. Your monthly payment is usually lower than your previous electric bill, so you save money from day one without any financial commitment beyond the lease agreement.

According to ENERGY STAR, understanding the financial aspects of going solar before committing is essential. With a lease, the financial structure is simpler upfront but the total savings over the life of the agreement are significantly lower than what an owner would realize, because the leasing company keeps the tax credits, the incentives, and a portion of the energy savings as their profit.

Total Savings Over Time

This is where the difference between buying and leasing becomes most dramatic. A homeowner who buys a solar system outright or pays off a solar loan typically saves sixty thousand to one hundred thousand dollars or more in electricity costs over the twenty-five-year life of the panels. After the system is paid off, every kilowatt-hour it produces is free.

A homeowner who leases the same system saves significantly less because the monthly lease payment continues for the entire term. The savings come from the difference between the lease payment and what they would have paid the utility, which is usually twenty to thirty percent less. Over twenty-five years, a lease might save fifteen thousand to thirty thousand dollars depending on the terms and local electricity rates.

The gap between the two grows wider over time because utility rates rise but a purchased system’s output costs nothing after the loan is paid. A lease payment may also escalate annually, with many contracts including a built-in increase of one to three percent per year. If utility rates don’t rise as fast as the lease escalator, the savings shrink and in some cases can disappear entirely in the later years of the agreement.

Tax Credits and Incentives

The federal solar tax credit is one of the most valuable financial benefits of going solar, and it’s only available to system owners. If you buy your panels, you can claim the credit on your federal tax return and reduce your tax liability by a significant percentage of the total system cost. If you lease, the leasing company claims the credit because they own the equipment.

The same applies to most state and local incentives. Property tax exemptions, sales tax exemptions, and utility rebates typically go to the system owner. The Database of State Incentives for Renewables and Efficiency provides a searchable list of every solar incentive available by state. Checking what’s available in your area before deciding between buying and leasing helps you understand exactly how much financial benefit you’d be leaving on the table with a lease.

What Happens When You Sell the Home

If you own your solar panels, they transfer to the new owner as part of the home sale, just like the roof, the HVAC system, or any other permanent improvement. Studies consistently show that homes with owned solar systems sell for more than comparable homes without solar, typically around a four percent premium. The panels are an asset that adds value to the property.

If you lease your panels, the situation is more complicated. The lease is a contract between you and the solar company, and it doesn’t automatically transfer to the buyer. The buyer has to agree to assume the lease, which means they need to qualify with the leasing company and accept the remaining payment terms. Some buyers are willing to do this. Others view an assumed lease as a liability rather than a benefit, and it can complicate or slow down the sale.

If the buyer doesn’t want to assume the lease, you may need to buy out the remaining balance of the lease before closing, which can cost several thousand dollars depending on how many years remain. This buyout cost comes out of your sale proceeds and can offset any premium the solar system might have added to the sale price.

Maintenance and Warranty

With a lease, the solar company is responsible for monitoring, maintaining, and repairing the system for the duration of the agreement. If a panel fails, the inverter breaks, or production drops below the guaranteed level, the leasing company handles it at no cost to you. This is a genuine convenience and one of the legitimate advantages of leasing.

With an owned system, you’re responsible for maintenance, but in practice solar panels require very little attention. There are no moving parts, and most systems operate for years without any intervention. The manufacturer’s product warranty covers defects for ten to fifteen years, and the performance warranty guarantees minimum output for twenty-five to thirty years. If you purchased through a reputable installer, their workmanship warranty covers the installation itself. The actual maintenance burden of owning solar panels is minimal for most homeowners.

When Leasing Makes Sense

Despite the financial advantages of buying, leasing is the right choice in a few specific situations:

• You don’t have the cash for a down payment and can’t qualify for a solar loan
• Your tax liability is too low to benefit from the federal solar tax credit, which requires enough tax owed to offset
• You plan to move within a few years and want to reduce your electricity costs in the short term without a long-term financial commitment
• You want guaranteed maintenance and monitoring without any ownership responsibility

If any of these apply to your situation, a lease can still deliver meaningful savings compared to paying full utility rates. It’s not the most financially efficient path, but it’s a valid one that puts solar on your roof with zero upfront cost and immediate bill reduction.

The Bottom Line

Buying your solar panels gives you more savings, more control, more incentives, and more home value than leasing. If you can afford the upfront cost or qualify for financing with a payment lower than your current electric bill, buying is the stronger financial decision in almost every scenario. Leasing trades long-term savings for short-term convenience and zero upfront cost, which makes it the better fit for homeowners who can’t buy but still want to benefit from solar energy.
