Solar Panel Installation near you

The sequence matters more than the equipment brochure. A site assessment measures the roof planes, shading and structure, and establishes whether the roof has enough service life left that you will not be paying to remove and reinstall an array in a few years. A design follows, then two parallel approvals: a building and electrical permit from the local authority having jurisdiction, and an interconnection application to the utility. Only after installation, inspection and the utility's final sign-off, commonly called permission to operate, may the system be switched on.

Washington's rules show what an inspector is actually holding you to, and they are more specific than most homeowners expect. Chapter 296-46B WAC requires that the photovoltaic system design review be available at the installation site at the time of the first inspection and until the inspection process is complete. It also treats structural work differently from electrical work: the portions of a support structure or foundation that are exclusively mechanical and are not part of a bonding or grounding path may be done by the owner, a registered general contractor or a licensed electrical contractor without an electrical permit or inspection, while all electrical work, including wiring installation and terminations, must be completed by the entity authorized to do that electrical work.

The same chapter shows how system voltage is fixed on paper rather than guessed on the roof: the open-circuit voltage temperature coefficients in the listed module's instructions are used to determine maximum direct current system voltage, and where they are not supplied the voltage is calculated using Table 690.7 of the National Electrical Code with a temperature correction factor of 1.25, unless another factor can be justified and is approved by the authority having jurisdiction. Your own jurisdiction will have its own amendments, so ask which edition of the NEC is enforced there before the design is finalized, not while the inspector is standing on your driveway.

There is no national solar installer's licence in the United States. California's Contractors State License Board defines the C-46 Solar Contractor as one who installs, modifies, maintains and repairs thermal and photovoltaic solar energy systems, and the classification is explicitly bounded: a licensee classified in that section may not undertake or perform building or construction trades, crafts or skills except when required to install a thermal or photovoltaic solar energy system. Florida takes a different route, defining a solar contractor in section 489.105 of the Florida Statutes as one whose services consist of the installation, alteration, repair, maintenance, relocation or replacement of solar panels for potable solar water heating systems, swimming pool solar heating systems and photovoltaic systems, while also providing that a contractor already certified or registered under that chapter is not required to become a solar contractor to perform work within their own scope.

Texas regulates the work and the sale separately, which is worth understanding because it is where most complaints start. The Department of Licensing and Regulation requires anyone who performs, or offers to perform, non-exempt electrical work in Texas to be licensed and to perform that work through a licensed electrical contractor, and it already regulated solar installation on that basis. The Residential Solar Retailer Regulatory Act, enacted in 2025 and found in Occupations Code chapter 1806, then added a layer over the selling of systems, with registration of solar retailers and salespersons beginning on September 1, 2026 and licensed electrical contractors exempt from the registration and insurance requirements but still subject to most of the Act.

The practical step is the same everywhere: ask which licence the company holds, in whose name, and verify the number with the issuing board rather than accepting a printed card or a logo on a truck. Ask, too, who pulls the permit and who meets the inspector, because a subcontracted crew working under somebody else's licence is a common arrangement and you are entitled to know whose licence your job is on.

The federal incentive that shaped residential solar economics was the Residential Clean Energy Credit under section 25D. The IRS describes it as equal to 30 percent of the costs of new, qualified clean energy property for your home installed any time from 2022 through December 31, 2025, and states plainly that the credit is not available for any property placed in service after December 31, 2025. Anyone still quoting that credit as part of your payback needs to explain, in writing, what they think you will actually be able to claim, because the date matters more than the percentage.

The detail of what once qualified is still useful for reading a quote. The IRS listed solar electric panels among qualified expenses and allowed labor costs for onsite preparation, assembly or original installation and for the piping or wiring that connects the property to the home. Used property was never eligible. Traditional building components serving a roofing or structural function generally did not qualify, so roof trusses and ordinary shingles supporting an array were out while solar roofing tiles and solar shingles were in, because they generate energy. Battery storage technology qualified from 2023 provided it had a capacity of at least 3 kilowatt hours. The credit was nonrefundable, with unused amounts carried forward.

The interaction with other money is the part most often misdescribed on a sales call. The IRS treats public utility subsidies for buying or installing clean energy property as a reduction in qualified expenses, whether the subsidy reaches you or your contractor, while utility payments for clean energy you sell back to the grid, such as net metering credits, do not affect qualified expenses. Rebates from someone connected to the sale, such as a manufacturer, distributor, seller or installer, are subtracted when they are based on the cost of the property. Treat the IRS page and your own tax adviser as the authority, and ask any installer to put incentive claims in writing rather than in a slide.

Export compensation is a state and utility matter, not a national rule, and it is the single biggest variable in whether a system pays for itself. The Department of Energy's homeowner guidance describes net metering as an arrangement in which system owners are compensated for solar generation exported to the grid, and is direct that whether your system qualifies depends on the policies and practices in your state and electric utility, with your local utility the place to find out what applies in your service area.

California is the clearest illustration of how much this can move. The California Public Utilities Commission reports that more than 90 percent of customer-sited solar capacity interconnected in the three large investor-owned utilities' territories sits on net energy metering tariffs, under which participating customers receive bill credits for exported generation at the retail rates they pay for consumption. Those tariffs are closed to new enrollments: since April 15, 2023, customers applying for interconnection have taken service on the net billing tariff adopted in decision D.22-12-056. A quote built on the older arrangement describes a deal that a new applicant in that state can no longer get.

The other half of the utility relationship is the interconnection itself. Washington's rule is blunt about who is in charge: anyone interconnecting a power production source to the utility distribution network must consult the serving utility and is required to meet all additional utility standards. Ask your installer which tariff you will actually be placed on, what the utility's interconnection queue looks like, whether a meter change is needed, and who is responsible if the utility requires equipment the quote did not include.

Residential solar has a sales problem serious enough that states have legislated against it, and knowing that changes how you read a pitch. Texas is the clearest recent example: the Residential Solar Retailer Regulatory Act requires that, from September 1, 2025, sales and lease contracts for residential solar energy systems contain specified contract provisions and disclosures and provide a five-day right to cancel the transaction, with provisions on deceptive and misleading practices and penalty enhancements taking effect alongside registration in 2026. Exemptions run to systems on multifamily buildings of four or more dwelling units or stories, nonresidential property, systems for temporary or emergency use, systems powering a single appliance, and small systems generating less than one kilowatt of peak output in the aggregate.

Even where your state has no equivalent statute, the same protections are worth insisting on in writing. Ask for the production estimate and the assumptions behind it, the equipment makes and models, who holds the workmanship warranty and for how long, what happens to the array when the roof needs replacing, and what the contract says if the utility imposes a different tariff than the one assumed. Treat any offer that expires at the end of the visit as a reason to slow down rather than to sign.

Financing deserves separate scrutiny from the hardware. A purchase, a loan, a lease and a power purchase agreement are four different transactions with different owners of the equipment, different rights to any tax benefit and different consequences when you sell the house. Ask specifically who will own the system, what happens at the end of the term, and what transferring the agreement to a buyer involves, and get those answers on paper before anything is scheduled.
