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.

California Home Solar and Battery Storage Incentives

If you live in California, you may be eligible for certain federal and state incentives.9

✓ Federal – Solar Investment Tax Credit

✓ State – Self-Generation Incentive Program


The Self-Generation Incentive Program (SGIP) only applies to battery storage. Customers of PG&E, SDG&E, SCE, and CSE may be eligible to receive a check from the state of California.10

The actual SGIP incentive amount varies by utility. If approved for the SGIP incentive, customers will receive a check from the state of California. Here is the breakdown by utility as of August 1, 2019. Please note that these may change as the SGIP incentive moves into different steps.

  • Southern California Edison (SCE) – Step 5 - SGIP incentive – ($2,900)
  • SoCalGas (SCG) – Step 4 - SGIP incentive – ($3,480)
  • Pacific Gas and Electric (PG&E) and CSE (San Diego Gas and Electric - SDG&E) - PG&E and CSE are currently placing applicants who apply for funds on a waitlist. The program will add applicants in the order in which they are received - the earlier you apply, the better. Projects will be funded as incentive funds become available from cancellations throughout the remainder of the program.

The amount of power available from the battery during a power outage is limited, depending on the loads connected, customer usage and battery configuration (i.e. batteries in certain areas may be set up to provide you with the best economic benefit, which may affect the amount of back-up power available). Solar systems and/or batteries may require repairs after weather events and such repairs may be delayed due to forces outside of our control. No assurances can be given that the solar system or the battery will always work. You should never rely upon either of these to power life support or other medical devices.
