A homeowner I spoke with had been told by a salesperson that leasing was “basically the same” as buying in terms of long-term savings, which is not accurate once you actually compare the total cost and ownership implications of each option directly, and understanding this distinction matters genuinely for making the choice that fits your actual financial situation.

The Core Structural Difference

When you buy a solar system (whether with cash or a solar loan), you own the equipment outright, are eligible for tax credits and incentives tied to ownership, and your electricity savings accrue entirely to you once any loan is paid off, with no ongoing payment to a third party for the system itself.

When you lease a solar system, a company owns the equipment and you pay a monthly fee (often structured to be lower than your previous electricity bill) for the right to use the electricity it generates. You generally do not receive the tax credits and incentives, since these go to the system’s actual owner — the leasing company — not to you as the homeowner using the system.

Why Tax Credits Make a Genuine Difference in Total Cost

The federal solar tax credit, along with various state and local incentives, can represent a meaningful percentage reduction in your total system cost when you own the system. Since lease arrangements mean the leasing company, not you, claims these credits, the genuine total value gap between buying and leasing is often larger than salespeople sometimes suggest when they frame the comparison primarily around monthly payment amounts rather than total financial outcome over the system’s full lifespan.

Calculating the Actual Long-Term Difference

For a system costing a given total amount when purchased, after applying available tax credits and incentives, compare this net purchase cost (plus any loan interest if financed) against the total of all lease payments over a typical lease term (commonly 20 to 25 years). In the cases I have walked through directly with homeowners, purchasing — even when financed with a loan — has generally produced a lower total cost over the system’s full lifespan compared to an equivalent lease arrangement, specifically because of the tax credit and incentive value that purchasing captures and leasing does not.

This does not mean leasing is never the better choice for any homeowner — it means the genuine financial comparison requires looking at total cost over the full term, not just comparing your current electricity bill to a proposed lease payment amount, which is the comparison many lease pitches tend to emphasize.

When Leasing Genuinely Makes More Sense

If you cannot use the tax credit. The federal solar tax credit is non-refundable, meaning it offsets tax you actually owe rather than being paid out as cash if you owe little or no federal tax. If your tax situation means you could not actually use a substantial credit, the gap between buying and leasing narrows considerably, since you would not have captured this value through ownership anyway.

If you genuinely cannot afford the upfront cost or do not want to take on a loan. Leasing requires little or no upfront payment in many arrangements, which matters genuinely for homeowners who want solar’s benefits without either a large upfront expense or taking on additional debt, even knowing this comes with a higher total cost over the lease term compared to ownership.

If you specifically want to avoid maintenance responsibility. Lease agreements often include maintenance as part of the arrangement, where the leasing company handles repairs and upkeep, which may be worth the cost difference for someone who specifically wants to avoid this responsibility, compared to an owned system where maintenance is generally the homeowner’s responsibility (though often manageable, since solar systems are relatively low-maintenance overall).

A Consideration Often Overlooked: Selling Your Home

If you anticipate selling your home before a lease term ends, this introduces genuine complexity, since the lease agreement generally needs to either transfer to the new buyer (who must qualify and agree to assume it) or be paid off, both of which can complicate a home sale in ways that an owned system generally does not, since an owned solar system is typically treated as a straightforward home improvement that can increase home value without this kind of transfer complexity.

This is genuinely worth considering if there is a reasonable chance you might sell your home within the lease term, since this potential complication is a real factor beyond the pure cost comparison discussed above.

Questions Worth Asking Directly Before Deciding

For a lease: What happens if I want to sell my home before the lease term ends? What are my buyout options if I want to purchase the system outright partway through the lease? What specific maintenance is actually covered, and what, if anything, falls to me?

For a purchase: What loan terms are actually available to me, and what is my actual qualifying interest rate? Can I realistically use the available tax credits given my specific tax situation, and would consulting a tax professional about this be worthwhile before committing?

A Quick Reference Summary

Consideration Buy Lease
Upfront cost Higher (unless financed) Generally low or none
Tax credits/incentives You receive these Leasing company receives these
Total cost over system lifespan Generally lower Generally higher
Maintenance responsibility Generally yours Often included in lease
Complexity when selling home Generally straightforward Requires lease transfer or payoff

What the Direct Comparison Showed That Homeowner

Walking through the actual total cost comparison, including the tax credit value the leasing arrangement would have forfeited, showed a meaningfully larger total cost gap than the “basically the same” framing the salesperson had suggested, though this particular homeowner’s specific tax situation and preference to avoid an upfront cost ultimately still made leasing a reasonable choice for their actual circumstances once they understood the genuine tradeoff they were making, rather than believing the two options were financially equivalent.

Are you weighing this decision for your own home? Describe your situation — particularly your tax circumstances and how long you expect to stay in your home — and I can help you think through which factors matter most for your specific case.
