Governments around the world are increasingly incorporating solar energy requirements into building policies. In 2025, a growing number of jurisdictions mandate or incentivize the inclusion of solar photovoltaic (PV) systems in new construction.
These government policies for solar panel integration aim to reduce greenhouse gas emissions, lower energy costs, and promote energy independence. The trend spans from local city ordinances to national laws, each tailored to regional goals and capabilities.
Many policies that advance the growth of solar energy are established at the state level. This can include state tax incentives for solar, which provide an additional tax benefit on top of the federal ITC. Other state policies, discussed below, can include:
The effectiveness of solar energy policies hinges on the ability of governments to align economic incentives with environmental goals. Countries that have successfully adopted solar power tend to have comprehensive policy frameworks that address the entire solar value chain—from manufacturing to grid integration.
