Installing solar is a project with a clear order of operations. The Department of Energy outlines a six-step process that moves from choosing an installer through permits and inspections. This guide summarizes each step so you know what comes next.
Choosing an Installer and Checking the Roof
The first steps set the foundation for the project. The Department of Energy advises finding a licensed and certified installer through research or referrals, and verifying credentials with organizations like the North American Board of Certified Energy Practitioners.
Next comes the roof itself. The Department of Energy states that a solar installer, roofer, or structural engineer should evaluate whether your roof can support panels, and notes it can often save money to install solar at the same time as a roof replacement.
Evaluating Potential and Energy Needs
The middle steps size the system to your home. The Department of Energy advises evaluating solar potential by considering geographic location, sun exposure, shading, and system type, using mapping tools or an installer assessment.
The agency then recommends calculating your energy needs by reviewing electricity bills for annual and seasonal use. The Department of Energy suggests conducting a home energy audit and accounting for future changes, such as buying an electric vehicle, so the system fits both current and future demand.
Financing, Permits, and Inspection
The final steps cover paying for and approving the system. The Department of Energy lists financing options of purchasing outright, solar loans, leasing, or a power purchase agreement, and notes that ownership provides tax credits while leasing does not. Because federal residential solar tax credit rules changed for systems placed in service after 2025, confirm the current credit and your eligibility with IRS Form 5695 guidance and energy.gov before relying on any amount.
The installer then handles approvals. The Department of Energy states that the installer secures required permits and schedules inspections, and that while installation takes days, permits and inspections can take weeks to months depending on local regulations. The agency notes the SolarTRACE tool estimates timelines for your jurisdiction.
