Public Safety Power Shutoffs


✓ Starting in summer 2019, California utilities may turn off your power during extreme weather or wildfire conditions. Power outages could last multiple days.4

During a grid outage, if you have home solar + battery storage, your solar system can continue to produce and store energy during the day to power your most needed lights and appliances.5 Protect your family and your home from blackouts with a battery.6

The cost of a power outage can vary widely. However, there are numerous hidden costs due to a power outage – think about the cost of emergency supplies, potential property damage, as well as the emotional cost caused by potential long-term power outages.

Maximize Time of Use Rates

PG&E, SDG&E, and SCE require time of use (TOU) rates for home solar systems. TOU rates mean that the price you pay for electricity varies based on the time of day you use it. You will pay less for electricity at times of the day when there is less demand on the electric grid, and pay more for electricity during times of day when there is more demand. These are often referred to as off-peak and on-peak periods. In some cases, pricing may also vary from season to season.
