Creates a Department of Energy program to expand access to community solar, with a focus on people without rooftop solar access and low- and moderate-income households; directs DOE to provide technical assistance and to incorporate community solar into its grant, loan, and financing programs where practicable. Adds a new community solar program standard to PURPA requiring most electric utilities to offer equitable community solar options (with Tribal utilities able to opt in) and sets deadlines for state regulators and nonregulated utilities to act. Also allows federal contracts for public utility services to run for up to 30 years.
