Solar Ownership vs PPA

The most important decision you'll make about going solar isn't which panels to buy — it's whether to own them.

When you start exploring solar energy, you'll quickly encounter two main paths: owning your solar system or signing a Power Purchase Agreement (PPA). While both put panels on your roof, the financial outcomes over 25 years are dramatically different.

At Solar Center by Dura-Foam, we believe strongly in solar ownership — and this page explains exactly why. We'll walk you through the real numbers, the hidden costs of PPAs, and how ownership puts tens of thousands of dollars back in your pocket.

The Bottom Line

Over 25 years, a homeowner who owns their solar system typically saves $30,000 to $50,000 more than someone who signs a PPA — and that's a conservative estimate.

Option 1

What Is Solar Ownership?

When you own your solar system, the panels on your roof belong to you — just like your water heater or HVAC system. You purchase the system outright (with cash or a solar loan) and receive all the financial benefits: the federal tax credit, energy savings, and increased home value.

Most homeowners finance their solar system with a low-interest solar loan that keeps monthly payments below their current utility bill. Once the loan is paid off (typically 7–12 years), your electricity is essentially free for the remaining 15–18 years of the system's life.

You also own an appreciating asset. Studies consistently show that owned solar systems increase home value by $15,000 to $25,000, and homes with solar sell faster than homes without.

Ownership at a Glance

  • You keep the 30% federal tax credit — worth $7,500+ on a typical system
  • Fixed or zero payments — no annual price increases
  • Increases home value — $15,000–$25,000 on average
  • Free electricity after payoff — 15–18 years of $0 bills
  • Full control — add batteries, expand, or transfer with your home
Option 2

What Is a Power Purchase Agreement (PPA)?

With a PPA, a solar company installs panels on your roof at no upfront cost — but they own the system. You agree to buy the electricity the panels produce at a set rate, typically for 20–25 years. It sounds simple, but the fine print matters enormously.

The PPA company keeps the federal tax credit (that's how they fund the "free" installation). They also keep any renewable energy credits. And most PPAs include an annual escalator clause — your rate increases 1–3% every year, regardless of what utility rates do.

If you want to sell your home, the new buyer must qualify for and agree to take over your PPA contract — or you'll need to buy out the remaining contract, which can cost $10,000–$20,000 or more.

PPA at a Glance

  • You don't get the tax credit — the PPA company keeps it
  • Rates increase annually — 1–3% escalator clauses are standard
  • No home value increase — panels aren't yours to sell
  • Complicates home sales — buyers must assume your contract
  • 20–25 year commitment — expensive to exit early

Side-by-Side Comparison

How ownership and PPAs stack up across every factor that matters.

Factor Solar Ownership PPA / Lease
Upfront Cost $0 down with solar loan, or cash purchase $0 down
Monthly Payment Fixed loan payment (often less than old utility bill); $0 after payoff Monthly PPA rate that increases 1–3% annually
30% Federal Tax Credit You keep it ($7,500+) PPA company keeps it
Home Value Impact Increases $15,000–$25,000 No increase (may deter buyers)
System Control Full control — expand, add batteries, modify No modifications allowed without company approval
Selling Your Home System transfers with home; adds value Buyer must assume contract or you pay buyout ($10K–$20K+)
Contract Length Loan: 7–20 years; then free electricity 20–25 years; payments never stop
25-Year Total Savings $50,000–$80,000+ $15,000–$30,000
Maintenance Covered by manufacturer warranty (25 years); minimal upkeep PPA company handles maintenance
Equipment Warranty 25-year manufacturer + installer warranty PPA company responsible for equipment

5 PPA Gotchas Most People Don't See Coming

Before you sign a 25-year PPA contract, make sure you understand what you're agreeing to.

1

The Escalator Clause

Most PPAs increase your rate 1–3% every year. A rate that starts at $0.15/kWh grows to $0.30/kWh by year 25. If utility rates drop or stay flat (thanks to more renewables on the grid), you could end up paying more for PPA electricity than grid power.

2

No Tax Credit for You

The 30% federal Investment Tax Credit is worth $7,200+ on a typical system. With a PPA, the solar company claims this credit — it's how they fund the "free" installation. That's your money going to their bottom line.

3

Selling Your Home Gets Complicated

When you sell, the buyer must qualify for and agree to assume your PPA. Many buyers don't want a 15-year payment obligation they didn't choose. If they refuse, you'll need to buy out the contract — often $10,000–$20,000+. Some deals have fallen through entirely over this.

4

No Equity, No Asset

With a PPA, 25 years of payments buy you nothing. You never own the panels. You never build equity. When the contract ends, the company can remove the system entirely. With ownership, you have an asset that pays for itself many times over.

5

Limited Roof Access

Need a new roof? The PPA company must remove and reinstall the panels — at your expense, or after lengthy coordination. Want to add a battery or expand your system? You'll need their permission, and they may say no. It's your roof, but it's their equipment.

Don't get locked in.

Why Solar Center Recommends Ownership

At Solar Center by Dura-Foam, we don't offer PPAs or leases. That's a deliberate choice, not a limitation. We believe every homeowner deserves the full financial benefit of going solar — not a fraction of it.

Here's our perspective: when a PPA company puts "free" panels on your roof, they're not doing you a favor. They're using your roof as real estate for their investment. They collect the tax credit, they collect your monthly payments, and they own the asset. You get a modest discount on electricity — at least at first.

We think you deserve better. Our $0-down solar loan options make ownership just as accessible as a PPA — with one critical difference: everything you pay goes toward an asset you own. After your loan is paid off, you enjoy 15+ years of free electricity and a home that's worth more.

As a division of Dura-Foam Roofing, we also bring something PPA companies can't: deep roofing expertise. We know how to install solar systems that protect your roof's integrity and last for decades. When you own your system and it's installed by a company that understands roofing, you have the best of both worlds.

Common Questions About Solar Ownership vs PPAs

Can I really go solar with $0 down if I own the system?
Yes. Solar loans with $0 down are widely available. Your monthly loan payment is typically less than your current utility bill, so you start saving from day one. After the loan is paid off, your electricity is essentially free. You still receive the full 30% federal tax credit, which you can apply to the loan balance or keep.
What if I can't use the full tax credit?
The federal solar tax credit can be carried forward to future tax years. If your tax liability is lower than the credit amount in the year of installation, you can apply the remaining credit to subsequent years. We recommend consulting with a tax professional about your specific situation.
Are there any situations where a PPA makes sense?
PPAs were originally designed for commercial properties and non-profits that can't use the federal tax credit. For homeowners with tax liability, ownership is almost always the better financial choice. If you've been told you "don't qualify" for ownership, call us — we work with multiple lenders and can usually find a path to ownership.
What happens to my solar system if I sell my home?
With an owned system, the solar panels transfer with your home and increase its value. Buyers see owned solar as a premium feature. With a PPA, the buyer must agree to take over your contract, which can delay or derail the sale. Some homeowners have had to pay $10,000–$20,000+ to buy out their PPA just to close on a home sale.
How does Solar Center's warranty compare to a PPA?
Our owned systems come with 25-year manufacturer warranties on panels and inverters, plus our workmanship warranty backed by Dura-Foam's decades of experience. PPA companies handle maintenance, but that's because they own the equipment — not because they're doing you a favor. With ownership, your warranties are just as comprehensive, and you own the asset at the end.
