National vs Local Solar Installer: Which Is Right for Your Home
Written by HyreSolar Research Desk Primary-source research and fact checking
Quick answer
National vs Local Solar Installer comes down to upfront cost, lifetime savings and how long you plan to stay in the home; here is each factor side by side.
The useful question is not big versus small but which legal entity signs your contract, which one’s crew is on your roof, and which one owes the workmanship warranty.
A national brand may do all three itself, or it may sell through local dealers and subcontractors, and two of the largest companies describe opposite structures in their own SEC filings.
A local installer usually signs, installs and warrants as one company, so you are judging one firm’s track record and license.
Neither model is proven to install better; they differ in who is liable when something goes wrong.
Cost side by side
Installed prices as other publishers state them, gross of incentives. Each range is the median published low to the median published high across at least 12 dated sources, retrieved October 21–22, 2026; the source rows sit on the linked cost page.
| Option | Published range | Sources |
|---|---|---|
| Installed price per watt, all installers | $2.58/W–$3.36/W | 21 dated |
No 30% federal credit is subtracted: Section 25D ended for expenditures after December 31, 2025.
National brand vs local installer on the factors that differ
| National brand | Local installer | |
|---|---|---|
| Who signs your contract | The brand, or a state subsidiary, or a dealer, depending on the company | Usually the installing company itself |
| Who is on your roof | Employees or subcontracted installation partners | Usually its own crew |
| Who owes the workmanship warranty | Varies: Sunrun says it is "ultimately responsible"; Sunnova’s dealers owed it to Sunnova, not you | The installing company |
| Financing options | Often in-house leases, PPAs and loans | Usually cash and third-party loans; some offer third-party leases |
| Failure risk | Can sit in a dealer, a state subsidiary or the financier | Concentrated in one company |
| What to verify | The legal entity on the contract and the license on the permit | The license, the qualifier and years trading |

Two national companies, two opposite answers
Sunrun’s annual report for 2025 keeps the contract in-house: "All contracts are between the customer and us, based on a price set by us." Its installation partners "are solely our subcontractors and do not enter into any agreements with our customers," and it is "ultimately responsible as the contracting party for every energy system installation."
Sunnova’s report for 2024 described the reverse. Its dealers "market, design, construct and install," obtain "professional licenses, including as contractors," and owe the workmanship warranty to Sunnova for up to 10 years; the company added "we do not control our dealers."
Sunnova filed for Chapter 11 on June 8, 2025, so in that structure the financier itself failed.
Brands can also be many companies. Titan Solar Power’s Chapter 7 case in the District of Arizona lists 26 affiliated debtors, 22 of them per-state corporations under one brand. A homeowner whose warranty ran to one state entity held a claim in that entity’s liquidation.
Why national reach means many licensed entities
A contractor license is held in the name of the entity that contracts. Arizona makes it unlawful to contract without "a contractor’s license in good standing in the name of" the person or company. Licenses do not travel between states, so a brand in thirty states needs thirty licensed entities, local subcontractors, or both.
Corporate licenses rest on a qualifying individual. California requires that person to supervise construction, caps one qualifier at three firms a year, and suspends the license automatically if a departure is not reported within 90 days (with 90 days to replace).
Florida allows 60 days and bars new work in the gap. A license being active today is partly a statement about one person.
Price and savings over 25 years
We found no primary source showing national or local installers are systematically cheaper. Compare quotes on price per watt for the same equipment (the proposal analyzer does the division) and on the cash price before any financing, because the CFPB found loan fees can add 10 to 30% of the cash price to the principal.
Over 25 years, the larger difference is often the warranty’s survival. Price the workmanship promise by who owes it and how long they have traded (see workmanship vs manufacturer warranty).
Which to choose if…
- 1You want a lease or PPA
National companies are the main providers. Read who owes service and the transfer-on-sale clause (see lease vs PPA).
- 2You are buying with cash or a loan
Get at least one local quote. A long-established, licensed local firm that signs and installs keeps liability in one place.
- 3Either way
Ask the CPUC’s four questions in writing: your company’s license number, the installer’s license number, whether the salesperson is an employee, and whether the job will be subcontracted.
- 4After the job is scheduled
Look up the permit. If the entity on it differs from the one on your contract, you now know the structure you are in.
