Solar Plus Solar plus increases customer system value through technologies such as electric batteries, smart domestic water heaters, smart air conditioner (AC) units, and electric vehicles (EVs).
How Does Solar Plus Work? • • •
Solar plus optimizes customer economics through load shifting. Solar plus technologies shift customer loads “under” the PV output curve, reducing grid electricity use. In time-of-use (TOU) rate structures, solar plus technologies can also shift grid electricity use from high-rate to low-rate periods.
Traditional Water Heating Typical electric water heaters heat water after each hot water draw to keep water around a target temperature (e.g., 125°F)
Smart Water Heating The smart domestic water heat controls how and when the unit heats water. The unit uses PV output to pre-heat water to 180°F. After PV is no longer available, the unit allows water temperature to “drift” down to 120°F without using grid electricity to heat water.
Traditional AC A traditional AC unit maintains home temperature within some “deadband” (e.g., 70°F-72°F). The AC unit turns on each time the home’s temperature reaches the upper end of the deadband.
Smart AC The smart AC unit controls how and when the AC unit cools the home. The AC unit uses PV output to pre-cool the home to 66°F. The AC unit then allows the home’s temperature to “drift” up to 74°F without using grid electricity.
