When homeowners start exploring solar, the first fork in the road is ownership: do you buy a solar system outright (with cash or a loan), or do you sign a Power Purchase Agreement (PPA) where someone else owns the system and you buy the electricity it produces?
Both options reduce your electricity costs compared to staying with SCE. But they work very differently in terms of upfront cost, ownership, maintenance responsibility, tax implications, and long-term financial outcome. This article covers each factor honestly so you can make the right decision for your situation.
1. Quick Side-by-Side Comparison
2. What Is a Solar PPA?
A Power Purchase Agreement is exactly what it sounds like: an agreement to purchase power. A solar company (in this case, Freedom Forever) installs solar panels on your roof at no cost to you. They own the system. You agree to buy the electricity it produces at a rate that is lower than what SCE charges.
Key terms of a typical Freedom Forever PPA:
The PPA model works because it aligns incentives. Freedom Forever makes money when your panels produce electricity. You save money because their rate is lower than SCE's. Both parties benefit from maximum production — which is why they guarantee it in writing.
3. What Does Buying Mean?
Buying solar means you purchase the entire system — panels, inverters, mounting hardware, battery (if included) — and own it outright. You can pay cash upfront or finance it with a solar loan. Either way, the system is your property.
What buying looks like in practice:
Buying maximizes long-term financial return — if you have the cash or borrowing capacity, and if you are comfortable taking on the ownership responsibilities. The total savings over 25 years are generally higher with ownership because there is no 3.5% annual escalator.
4. Upfront Costs: The Real Barrier
The single biggest practical difference between PPA and buying is the upfront cost. A typical residential solar system in Temecula (7-10 kW) costs $25,000 to $35,000 before tax credits. Add a battery and it can reach $40,000 to $45,000 or more.
The 30% federal residential tax credit (Section 25D) that previously reduced these costs expired December 31, 2025. For 2026 installations, homeowners pay the full system cost. At $25,000–$35,000 out of pocket for a cash purchase, the PPA route has become comparatively more attractive for a larger share of homeowners.
Solar loans solve the upfront cost problem but introduce their own tradeoffs. With interest rates in the 5-8% range for solar loans as of 2026, the monthly loan payment may be similar to or higher than your current SCE bill for the first several years. The math works out over time (especially as SCE rates rise), but the immediate cash flow improvement is smaller than with a PPA.
The PPA eliminates this barrier entirely. Zero down, zero installation cost, and you start saving from month one. The tradeoff is that your long-term savings are lower because you are paying the PPA company's rate (with the 3.5% escalator) instead of generating free electricity.
5. Long-Term Savings Comparison
For a Temecula home using 1,000 kWh per month, here is how the two options compare over 25 years (assuming SCE increases at 7% per year):
The math is clear: buying produces higher total savings over 25 years. But it requires $30,000+ upfront (no federal credit available in 2026) and involves taking on ownership risk and maintenance responsibility. The PPA produces lower total savings but with zero upfront investment and zero risk.
Both options are dramatically better than staying with SCE and paying escalating rates for 25 years. The estimated total SCE cost for 1,000 kWh/month over 25 years (at 7% annual increase) exceeds $260,000. Either solar option cuts that roughly in half or more.

6. Maintenance and Warranty
This is an underappreciated difference between PPA and buying.
With a PPA: Freedom Forever owns the system and is responsible for all maintenance, monitoring, and repairs for the full 25-year term. If a panel fails, they replace it. If an inverter dies, they fix it. If production drops below the guaranteed amount, they credit you. You do literally nothing except pay your monthly PPA bill.
When you buy:You own the equipment and are responsible for it. Panel manufacturers typically warrant panels for 25 years, but that warranty covers manufacturing defects — not everything that can go wrong. Inverters have shorter warranties (10-15 years typically) and may need replacement during the system's life. Monitoring, cleaning, and general upkeep are on you. If something goes wrong after the installer's workmanship warranty expires (usually 5-10 years), you are hiring someone to fix it.
For homeowners who want a hands-off experience — install it, forget about it, just pay a lower bill — the PPA's included maintenance is a significant advantage. For homeowners who are comfortable managing home systems and want maximum long-term financial return, buying makes sense despite the maintenance responsibility.
7. Tax Credits: Who Gets What
The federal solar tax credit is one of the most misunderstood aspects of going solar. Here is how it works for each option:
PPA (Section 48E)
The system owner (Freedom Forever) claims the commercial Investment Tax Credit under Section 48E. You never owned the system, so you were never eligible for the residential credit. However, the tax credit benefit is effectively passed through to you in the form of a lower PPA rate. Without the tax credit, your PPA rate would be higher.
Buying (Section 25D — Expired)
Section 25D — the 30% residential solar purchase credit — expired December 31, 2025, under the One Big Beautiful Bill. If you purchase a solar system in 2026 or later, there is no federal residential tax credit available. The savings case for buying now relies entirely on rate comparison and long-term ownership economics.
A critical timing note: the commercial Section 48E credit that enables today's PPA rates requires construction to begin by July 4, 2026. If this deadline passes, PPA starting rates will likely increase because the installer loses the tax benefit. This is a real federal deadline that directly affects pricing.

8. Who Should Choose Which?
A PPA Is Best If You...
- Do not have $20,000-$45,000 available or do not want to tie it up
- Prefer a completely hands-off experience with no maintenance responsibility
- Want to start saving from month one with zero risk
- Are not sure you will stay in the home for 10+ years (PPA transfers to buyer)
- Do not want $30,000+ upfront — the residential tax credit expired Dec 31, 2025
- Value simplicity and predictability over maximizing total return
Buying Is Best If You...
- Have cash available or strong borrowing capacity
- Have cash available — no federal purchase credit in 2026; full cost is out of pocket
- Are comfortable managing equipment maintenance and warranties
- Plan to stay in the home for 10+ years to maximize return on investment
- Want to maximize total lifetime savings (higher total but requires upfront capital)
- Want to increase your home's assessed value through owned solar
The Bottom Line
Neither option is universally "better." The PPA is the right choice for homeowners who prioritize zero upfront cost, zero risk, and a completely hands-off experience. Buying is the right choice for homeowners who have capital available and want to maximize total lifetime savings.
What both options share: they are both dramatically better than the third option — staying with SCE and absorbing uncapped rate increases for the next 25 years.
