Across the Bay Area, power outages are no longer rare disruptions—they’re an expected part of life. Between wildfire-related shutoffs, aging utility infrastructure, and extreme weather, blackouts are happening more frequently and lasting longer than ever before.
For homeowners, especially retirees or those working from home, the impact can be immediate and stressful: no lights, no refrigeration, no heating or cooling, and no way to charge devices or medical equipment.
The solution? Solar with battery backup.
If you’ve already invested in solar—or you’re considering it—adding battery storage transforms your system into a reliable power source that keeps your essentials running, even when the grid goes down.
Here’s how solar + battery systems work during a blackout, and why more Bay Area homeowners are making the switch.
Understanding Bay Area Blackouts
In 2024 alone, PG&E issued dozens of Public Safety Power Shutoff (PSPS) events across Northern California. These preemptive shutoffs aim to reduce wildfire risk but leave thousands without power for hours—or even days.
Outages in the Bay Area can be caused by:
- PSPS events in fire-prone areas like the East Bay hills and North Bay
- Overloaded transformers during heat waves
- Windstorm-related tree damage to utility lines
- Rolling blackouts due to statewide energy shortages
For residents in counties like Alameda, Contra Costa, Santa Clara, and Marin, blackouts are an increasingly common challenge. The question is no longer if the power will go out—but how prepared your home is when it does.
How Solar + Battery Backup Keeps Your Lights On
A standard rooftop solar system without a battery must shut down during a blackout for safety. That’s because solar panels are grid-tied, and operating them while linemen are repairing power lines could be dangerous.
But with a battery backup system, your home automatically switches to your stored solar energy, allowing you to keep critical circuits powered until the grid is restored.
How the System Works:
- Solar panels generate electricity during the day
- Excess energy is stored in the battery instead of being sent to the grid
- When the grid goes down, a smart inverter isolates your home from the grid
- Your battery powers key systems, like lighting, refrigeration, outlets, Wi-Fi, and medical devices
With no noise, no fumes, and full automation, battery systems offer a cleaner, quieter, and smarter alternative to generators—especially for homes in wildfire zones.
Why Retirees and Eco-Conscious Homeowners Are Investing in Backup
Peace of mind is one of the top reasons our customers install battery backup. For retirees, it means staying safe and comfortable at home—even when the grid fails. For environmentally minded homeowners, it means reducing dependence on fossil fuels and making better use of the solar power they generate.
Benefits for Prepared Homeowners:
Keep critical appliances running (fridge, lights, medical equipment, Wi-Fi)
- Avoid food spoilage, heat loss, or communication disruptions
- Reduce reliance on noisy, fuel-powered backup generators
- Charge EVs during prolonged outages
- Monitor system status from a smartphone or tablet
With outages now expected during both summer heatwaves and fire season, more Bay Area households are choosing solar + battery systems not just for energy savings, but for year-round reliability and resilience.
What Can a Home Battery Power During a Blackout?
Battery capacity is customized based on your needs. Some households want to back up the entire home. Others prioritize essentials. Our design team at Sunlight Electrical Solutions helps you determine what’s most important—and we size your system accordingly.
Commonly Backed-Up Items Include:
- LED lights and power outlets
- Wi-Fi routers and phone chargers
- Refrigerators and freezers
- Medical devices (oxygen concentrators, CPAPs)
- Heating systems and fans
- Security systems and smart locks
Larger homes or families with greater needs can choose to stack multiple batteries for extended runtime or whole-home coverage.
Warranty Coverage That Brings Peace of Mind
One of the top concerns among homeowners is long-term system reliability. At Sunlight Electrical Solutions, every eligible battery + solar system is backed by Solar Insure Total 30 or Solar 30 protection—third-party warranties that provide 30 years of coverage.
