Solar power policies are the rules and incentives that affect the development, deployment, and operation of solar power systems. These policies can be implemented at different levels of government, such as federal, state, or local; and by different actors, such as utilities, regulators, or consumers. Examples of solar power policies include renewable portfolio standards (RPS), which require utilities to source a certain percentage of their electricity from renewable sources; net metering, which allows consumers to sell excess electricity generated by their solar panels back to the grid at a favorable rate; feed-in tariffs (FIT), which guarantee a fixed price for electricity produced by solar power systems; tax credits, rebates, and grants, which reduce the upfront cost of installing solar power systems or provide cash incentives for doing so; and community solar, which enables multiple consumers to share the benefits of a single solar power system located off-site.
