Reduce your electricity bill if your utility offers a time-of-use rate plan. In areas that offer time-of-use (TOU) rate programs, a solar system paired with a Tesla battery can store your solar production during the day and shift it to times when TOU rates are high. With the Tesla app, you can also monitor your solar energy in real time and set your preferences to optimize for energy independence, outage protection or savings. Control your system from anywhere with remote access and instant alerts.
