Examples include rooftop solar, backup batteries, emergency diesel generators, controllable loads, and even electric vehicles that can store excess power.\u003C\u002Fp>\n\u003Cfigure class=\"my-6\">\u003Cimg src=\"https:\u002F\u002Fxxdpdyhzhpamafnrdkyq.supabase.co\u002Fstorage\u002Fv1\u002Fobject\u002Fpublic\u002Fcovers\u002Finline-1781011979183-t1e1.png\" alt=\"DOE explains solar DER and microgrids basics\" class=\"rounded-xl w-full\" loading=\"lazy\" \u002F>\u003C\u002Ffigure>\n\u003Cp>It also explains how microgrids differ from ordinary local generation. A microgrid can disconnect from the main grid and run autonomously, either for a single customer or for a larger site such as a substation, campus, military base, or community.\u003C\u002Fp>\u003Cul>\u003Cli>About one-third of U.S. solar energy comes from small-scale systems, including rooftop arrays.\u003C\u002Fli>\u003Cli>Behind-the-meter solar produces electricity on-site, so customers do not pay the utility for that generated power.\u003C\u002Fli>\u003Cli>Net metering can credit customers for excess electricity sent back to the grid.\u003C\u002Fli>\u003Cli>Microgrids can keep serving local loads during outages and help with restoration after major events.\u003C\u002Fli>\u003C\u002Ful>\u003Cp>The page also notes that DER are changing how electricity is produced and consumed. Households and businesses can act as both users and partial producers, while storage and software can shift demand away from peak periods and help balance supply.\u003C\u002Fp>\u003Cp>For islanded operation, the DOE warns that control systems matter. Without the larger grid to stabilize voltage and frequency, a disconnected system can damage equipment or create safety risks, which is why many solar systems are programmed to detect islanding and shut down when needed.\u003C\u002Fp>\u003Ch2>Why it matters\u003C\u002Fh2>\u003Cp>For developers, utilities, and grid planners, the message is practical: distributed solar is no longer just a rooftop add-on. It is becoming part of a broader system that can support resilience, local reliability, and faster recovery after storms or other disruptions.\u003C\u002Fp>\n\u003Cfigure class=\"my-6\">\u003Cimg src=\"https:\u002F\u002Fxxdpdyhzhpamafnrdkyq.supabase.co\u002Fstorage\u002Fv1\u002Fobject\u002Fpublic\u002Fcovers\u002Finline-1781011979757-h5ya.png\" alt=\"DOE explains solar DER and microgrids basics\" class=\"rounded-xl w-full\" loading=\"lazy\" \u002F>\u003C\u002Ffigure>\n\u003Cp>The DOE also points to black start use cases, where small generators and microgrids help restart larger power plants after a widespread outage.
