What “zero down” usually means
When a company says “zero down” it typically means you aren’t paying cash at installation. That doesn’t mean the system is free. Zero-down offers can take several forms: a lease or power purchase agreement (PPA) where you pay a monthly fee without owning the panels; a loan with no initial payment but monthly repayments later; or promotional financing that defers payments for a time. Each arrangement affects who owns the system, who claims tax credits, who is responsible for maintenance, and how much you pay over the life of the system. Which outcome applies depends on the contract, financing, your roof and your utility usage, so read the fine print and ask for itemized terms before you sign.
National brands vs local installers: what changes and what doesn’t
National firms like Sunrun, Sunnova, and Freedom Forever often run large sales and financing programs across many states. They can offer standardized contracts, company-backed financing, and centralized customer service. Local installers tend to be smaller, may give more customized system designs, and often handle permits and service directly in your neighborhood. Neither approach is automatically better. National companies can bring scale and available finance products; local installers can offer quicker response times, closer oversight during installation, and a sense of local accountability. Pricing, contract terms, and long-term service quality will vary by company and by installer crew — and by your roof, local regulations, and utility rate — so compare detailed proposals rather than trusting brand size alone.
What to compare before you request quotes
Get the same information from every company so you can compare apples to apples. Key items to ask for and compare: - Contract type: ownership (loan or cash), lease, or PPA — who owns the panels? - Total expected cost: monthly payments, fees, any escalators, and projected lifetime cost. - System size and production estimate: how many kW and expected annual output, and the assumptions behind the estimate. - Equipment details: panel brand and model, inverter type, and whether components are replaceable. - Warranties and guarantees: what’s covered, who honors them, and how claims are handled. - Maintenance and repairs: who pays for service and how quickly issues are handled. - Terms for moving or selling your house: transferability, buyout options, and early termination fees. - Permits, interconnection, and inspections: who handles them and how delays are managed. - Installer credentials: licenses, insurance, local references, and recent project photos. Always ask for a written, itemized proposal that shows the assumptions behind production and cost estimates — location, roof condition, and utility usage have major impacts on results.
Red flags and must-ask questions
Watch for vague answers and missing documents. Ask these questions to expose risky terms: - Can you show the full contract and an example final invoice before I commit? - Who will own the system and who claims tax credits or incentives? - What happens if I sell the house or need a roof repair? - Are there escalator clauses that increase payments over time? - Who services the system locally, and how quickly do they respond? - Are there early termination or transfer fees, and how are buyouts calculated? - Can you provide recent local references and proof of licensing and insurance? If answers are evasive, written details are missing, or the salesperson pushes for a fast signature, take more time and get a second opinion. A zero-down offer that can’t be explained clearly in writing is a warning sign.
