Key facts
- The 30% federal solar Investment Tax Credit (ITC) expired for new systems installed in 2026.
- Net metering policies vary widely, with some states offering full retail credit and others minimal compensation for excess solar power.
- State-level incentives such as tax credits, rebates, and property tax exemptions are now primary financial benefits for solar.
- Approximately 44 states protect homeowners' rights to install solar despite HOA restrictions.
- Permitting timelines have improved in many states, though California and New York remain slow.
Homeowners looking to install solar panels are facing increased costs and complexity as states revise their policies. The expiration of the 30% federal Investment Tax Credit (ITC) at the end of 2025 for most 2026 installations marks a significant shift, making state-level incentives and net metering rules more critical than ever.
Net metering, which compensates solar system owners for excess electricity sent back to the grid, varies dramatically by state. Some states, like New Jersey and Massachusetts, offer full 1:1 retail credit, while others provide minimal compensation. This disparity significantly impacts the financial return on investment for solar installations.
State governments are actively adjusting their incentive programs, which include tax credits, rebates, and property tax exemptions. These incentives are now the primary financial drivers for going solar, alongside long-term energy savings. States with robust Renewable Portfolio Standards (RPS), such as New Jersey and Nevada, are mandating higher renewable energy usage, which in turn drives investment in solar infrastructure and adoption.
While approximately 44 states have laws protecting homeowners' rights to install solar despite Homeowners Association (HOA) restrictions, the enforcement and scope of these protections can differ. Permitting timelines have seen improvements in many areas due to streamlined processes like SolarAPP+, though states like California and New York continue to experience slower review periods.
Experts suggest that the best states for solar in 2026 will be those offering a combination of incentives: state tax credits, favorable net metering policies, property tax breaks, and efficient permitting processes. Community solar programs are also expanding access for renters and individuals whose homes are not suitable for rooftop installations.
