Then ask what the solar system is supposed to do:</p> <ul> <li>offset annual electricity use</li> <li>reduce daytime grid use</li> <li>charge a home battery</li> <li>support outage backup</li> <li>prepare for EV charging, heat pump, or induction cooking</li> </ul> <p>Future electrification can change the load profile, so do not size from last year&rsquo;s bills if you know major loads are coming.</p>
