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.
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
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.
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.
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.
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.
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.
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.

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.
