Palmetto vs Sunrun: 2026 Comparison
Two different theories of residential solar: own the customer through software, or own the system through a lease.
By Alex Rivera, Senior Solar Editor · Updated 2026-07-02Palmetto is the stronger fit for buyers who want ownership economics with modern software: its marketplace model (vetted local build partners + Palmetto's platform and monitoring) typically prices cash and loan systems below big-national quotes, and its LightReach lease exists where third-party ownership makes sense. Sunrun remains the giant of leased solar — if a $0-down lease or PPA with maintenance handled forever is the goal, its scale, storage attach rates, and grid-services programs are unmatched. Buying your system in 2026 (the post-§25D-credit era rewards sharp cash pricing): quote Palmetto against two locals. Committed to leasing: Sunrun is the benchmark.

Choose Palmetto if...
- You're buying (cash or loan) and want marketplace pricing pressure on the quote.
- You like a single software layer for monitoring regardless of who built the array.
- Your state has strong local installers Palmetto can pit its platform against.
- You want ownership's long-run economics now that the §25D credit era has ended for 2026 purchases.
Choose Sunrun if...
- You want $0-down solar with maintenance someone else's problem for 20–25 years.
- Battery + grid-services income programs (where offered) appeal to you.
- You value the biggest operating fleet's service infrastructure.
- You've compared the lease's all-in cost per kWh against owning and accept the premium.
How do Palmetto and Sunrun actually differ?
Palmetto runs an asset-light marketplace: it sells, designs, and monitors through its platform while certified local partners build. That keeps quote pressure on labor — the platform can reprice across partners — and historically lands its ownership quotes under the big verticals' sticker for comparable equipment.
Sunrun is the opposite bet: it owns the largest residential solar fleet in America and makes its money operating leased systems for decades. The homeowner buys electricity or rents equipment; Sunrun handles everything else. Neither model is 'better' — they price different products: a system versus a service.
How did the 2026 tax-credit change shift this matchup?
The §25D residential credit is unavailable for 2026 cash purchases — homeowners now pay full freight, which makes every point of installer margin visible and rewards Palmetto's marketplace pricing. Our six-state payback research shows ownership still winning long-run in high-rate states, but with paybacks stretched versus the credit era.
Third-party ownership changed differently: commercial-side credits flow to lease operators like Sunrun, letting TPO pricing absorb part of what homeowners lost — one reason leases regained share in 2026. The catch remains the contract: escalators up to ~3.5%/yr compound over 25 years, so demand the full payment schedule and a cents-per-kWh comparison against your utility's trajectory.
Who stands behind the system longer?
Under a Sunrun lease, performance is contractually Sunrun's problem — monitoring, repairs, inverter swaps — for the term. That's the model's genuine luxury. Owned systems lean on stacked warranties: 25-year panel/product warranties, 10–25 years on inverters, and workmanship coverage that varies by Palmetto build partner (get the partner's certificate, not just the platform's promise).
Service texture differs too: Palmetto's software-first support is responsive digitally; Sunrun's scale means established processes but also queue times reviewers grumble about in peak seasons. For both, put every performance claim in the contract — verbal production promises don't survive 25 years.
Frequently Asked Questions
Common questions about Palmetto vs Sunrun.
Is Palmetto cheaper than Sunrun?
For purchased systems, usually — Palmetto's marketplace model typically quotes below big-national ownership pricing. Sunrun's lease hides the sticker entirely; compare its 25-year payment stream per kWh against owning to see the real premium.
Who installs Palmetto systems?
Certified local build partners under Palmetto's design, platform, and monitoring — you get local labor with a single national software layer. Ask for your specific partner's workmanship warranty in writing.
Is a Sunrun lease worth it in 2026?
It can be for $0-down buyers who value zero maintenance — and TPO captured tax benefits homeowners lost in 2026 — but escalator clauses (up to ~3.5%/yr) compound hard over 25 years. Demand the full schedule and compare cents-per-kWh.
What is LightReach?
Palmetto's own lease/PPA product, offering third-party ownership through its partner network where TPO economics fit — its answer to Sunrun's core product.
Did the 2026 tax credit change kill buying solar?
No — it stretched paybacks. Our six-state research still shows ownership beating leases long-run in high-rate markets; the credit's end simply makes sharp installer pricing (Palmetto's specialty) more decisive.
Who has better warranties?
Sunrun's lease wraps everything for the term by contract. Owned Palmetto systems stack manufacturer warranties (25-yr panels) plus the build partner's workmanship coverage — strong, but verify the partner's certificate.
