Who Should Own Your Solar Panels? A Lease vs. Buy TCO Comparison

Who owns the wind turbines in Texas? That seems like a weird way to start an article about solar panels. But it's the exact question that reframed how I evaluated solar for our office.

The short answer: most wind turbines in Texas are owned by independent power producers—not by the landowners, and not by the utilities buying the electricity. The landowner leases the ground. The utility or corporation signs a long-term power agreement. The developer owns the machine and carries the risk.

When I took over purchasing for a 50-person company in 2020, our operations manager asked me to "look at solar." I manage about $90,000 a year in vendor spending, so a $20,000 energy decision was firmly in my lane. But I'd been burned before by vendors who looked cheap on paper. I wasn't going to fall for "lease solar panels for less than your electric bill!" without seeing the fine print.

I compared lease offers and purchase quotes the way I compare any vendor—by total cost over the life of the asset, not by the first number on the first page. Here's what that comparison looked like.

Total cost of ownership = upfront cost + monthly payments + maintenance + downtime + tax benefits + end-of-contract outcome.

1. Cash Flow: $0 Down vs. Upfront Cost

The lease wins on cash flow. No debate. Every lease proposal we reviewed in 2024 had the same shape: zero down, a fixed monthly payment, and an annual escalator usually around 2-3%. A typical 6 kW system leased for about $90-140/month starting out, depending on the installer. I ran the full contract math—this is important—and the total payments added up to roughly $28,000-42,000 over 20 years. Don't hold me to those exact numbers, because they vary by state and installer, but the shape is right. And at the end, you own nothing. You either buy the panels at "fair market value" or the company takes them off your roof.

Buying the same system cost about $16,000-22,000 before incentives, based on quotes we collected in 2024 (prices vary; verify current rates). With the 30% federal investment tax credit for solar and storage under the Inflation Reduction Act, it came down to roughly $11,000-15,000. The payback in our area was around 6-9 years. After that, the electricity is essentially free.

If you want a perfect example of how small increases add up, look at the USPS stamp. First-Class Mail went from $0.55 to $0.73 between 2021 and January 2025 (Source: usps.com). That's a jump of over 30% in four years. A solar lease has its own built-in inflation—the escalator clause—and it does the same thing to your monthly payment.

So on pure dollar terms, buying wins. That's not the surprise.

The surprise is how much the escalator eats into the lease deal. A 2.9% annual increase sounds harmless. Over 20 years, a $100 monthly payment turns into about $190. The number you're shown at the sales pitch is almost never the bill you're paying in year eight. When you compare lease vs. buy, don't compare the first month—compare the sum of all 240 months.

2. Maintenance: "Them" vs. "You"

With a lease, maintenance is the provider's problem. That's the pitch, and it's genuinely nice—until the provider's timeline decides when your system works again.

If you've ever waited six weeks for a repair company to show up, you know how that feels. For a business, a solar inverter that's down for a month is a utility bill you still have to pay.

I have mixed feelings about maintenance plans. On one hand, they feel overpriced for what they deliver. On the other, after seeing how much downtime costs a business, I understand why some people pay for them.

When you own the system, the responsibility is yours. That sounds scary, but it's a nudge to buy reliable equipment and learn basic troubleshooting. This is where my experience with the ABB PVS-30-TL-SY comes in.

In 2024, one of our inverters threw a communication error. The service company quoted $300-500 for a visit. My facilities lead found an ABB support note, and we did a factory reset in about ten minutes. Fixed before lunch.

Here's something vendors won't tell you: a reset is a ten-minute job. But service companies charge their minimum dispatch anyway, because driving an hour for one small fix doesn't make economic sense for them. That's not greed. It's just business. But the cost lands on you. If you own, you can do safe, basic troubleshooting and save those calls.

My embarrassing moment: I knew I should've read the full manual before flipping the reset switch—not just the quick-start page. I thought, "what are the odds I mess this up?" The odds caught up with me. The factory reset wiped our Wi-Fi configuration and knocked the monitoring portal offline for an afternoon. Still fixed in ten minutes, but I had to explain to the ops manager why our easy fix caused a new problem. Lesson: the reset procedure is simple, but read the whole document before you touch the device.

3. Equipment: Who Picks What You Get?

This is the dimension most lease-buy comparisons skip, and it's where I made my worst assumption.

With a lease, the provider picks the equipment. Their goal is meeting the production promise at the lowest installed cost. The panels and inverters get chosen for the provider's economics, not your long-term experience. You live with that choice for 20 years.

When I priced out a purchase, I compared inverter specs myself. I assumed "same specifications" meant the same performance. It didn't. Two inverters had the same nameplate power rating, but one showed significant output derating above 100°F. In Texas. In July. That's the worst possible time to lose capacity.

That's why so many searches for "abb pvs-30-tl-sy factory reset inverter" exist—there's a huge installed base of ABB inverters still running in the field, and owners need documentation they can actually use. I kept seeing ABB show up in wind farm specs, EV charging stations, and installer manuals. That installed base matters: spare parts and support are easier to find. I chose ABB for our replacement because the support documents are easy to locate, the monitoring platform gives us near-real-time data, and the product comes from the same power electronics engineering as their utility-scale gear. It sounds boring, but boring is good when the hardware has to work for two decades.

And before you fall for any vendor's "100% recyclable" or "fully green" claims—per FTC guidance (ftc.gov), environmental claims have to be backed up with evidence. Ask them to put it in writing. Vague marketing words don't survive the first hard question from finance.

The Texas Wind Parallel

Back to the original question: who owns the wind turbines in Texas? The answer—independent power producers—is a reminder that ownership isn't always the end goal. It's a risk-and-capital decision.

Texas generates roughly a quarter of the nation's wind electricity (Source: U.S. Energy Information Administration, 2024). But most turbines there are owned by developers, not by the families whose land they stand on. The developer carries the capital cost and technical risk. The landowner gets lease income. The power buyer gets fixed, predictable pricing.

That's exactly what a solar lease does at a smaller scale. The lease company is the developer. You are the landowner. You get predictable costs; they get the tax credits, depreciation, and ultimate ownership of the asset. If you don't have the capital or the risk appetite—or the tax liability to use the credits—that can be a rational trade.

But there's a difference. In the wind industry, the landowner isn't the one paying for the developer's capital. In a solar lease, you are—through that monthly payment.

So, Lease or Buy?

Here's my honest answer after running the numbers for our company.

Buy if: you plan to stay in the building for 7-10 more years, you have the cash (or can finance at a reasonable rate), you can use the tax credit, and you're okay with basic maintenance. Your total cost over 20 years will almost certainly be lower.

Lease if: you're in a temporary space, your capital creates more value serving customers than sitting on a roof, you can't use the tax credits, or you'd rather have one predictable bill and no maintenance surprises. You'll pay a premium. Just be clear-eyed about what that premium is.

Before you sign anything, ask for the total of all payments over the full contract term—including the escalation schedule. If someone tells you not to worry about the escalator, remember the USPS stamp example. Small annual increases are exactly how the real cost creeps up.

One more note on battery storage: it changes the economics. Home solar panels and battery storage—or the commercial equivalent—raise your self-consumption, provide backup, and can help with demand charges. But a battery adds roughly $10,000+ to the upfront cost. Run the numbers for your utility rate structure first. We did, and the battery only made sense once our utility introduced demand charges.

We ended up buying our system. But if I were in a rented building with no idea whether we'd still be there in five years, I'd probably lease. This decision is about your situation, not about being "right."

Bottom Line

Renewable energy is usually pitched as a moral choice or a simple savings calculator. The reality is closer to what you'd see in the power industry: who owns the asset matters less than who carries the risk—and what that risk costs.

Compare lease vs. buy by total cost of ownership, not by the first month's bill. Check the escalator. Research the equipment, not just the panels. And if you need support for older ABB equipment like the PVS-30-TL-SY, the documentation is on ABB's official site—contact them at abb.com/contact and they'll point you to the right place. They got back to us within a day, which is more than I can say for some other vendors.

Take it from someone who learned the hard way: the cheapest quote is rarely the cheapest project. The same goes for solar.
