Tired of Losing Power During Storms? How Generac + Solar Keeps You Running

The lights flicker. Then silence. The hum of your refrigerator stops, your router goes dark, and you realize — you're on your own until the utility crew gets to your street. Again.
For millions of homeowners across the country, power outages aren't a rare inconvenience. They're a seasonal reality. And as storms grow more intense and the grid ages under increasing demand, the question is no longer if the power will go out — it's when.
The good news? There's a smarter way to protect your home. A Generac + solar system gives you the clean energy generation of solar panels backed by the reliable storage and backup power of a Generac PWRcell battery — so when the grid fails, your home doesn't.
Why the Grid Keeps Letting You Down
The U.S. electrical grid is aging. Much of the infrastructure was built in the mid-20th century and wasn't designed to handle today's energy demands, extreme weather events, or the complexity of modern power distribution.
According to the U.S. Department of Energy, Americans experience more power outages than any other developed nation. Weather-related outages have doubled over the past two decades, with hurricanes, winter storms, wildfires, and severe thunderstorms all contributing to longer and more frequent blackouts.
When a storm rolls through, it doesn't just knock out power for an hour — outages can last days or even weeks, leaving families without:
Heating or air conditioning
Refrigerated food and medications
Medical equipment that depends on electricity
The ability to charge phones and stay connected
Basic security systems and lighting
For most homeowners with standard solar panels, here's the hard truth: your solar system shuts off during a grid outage. That's right — grid-tied solar systems are designed to disconnect when the grid goes down, for the safety of utility workers. Without a battery backup, your panels are useless exactly when you need them most.
That's where Generac changes everything.
What Is the Generac PWRcell System?
Generac — the brand millions of Americans already trust for standby generators — has expanded into the solar and battery storage space with the PWRcell system, one of the most powerful home battery solutions on the market.
The PWRcell works seamlessly with solar panels to store the excess energy your system generates during the day. Then, when the grid goes down — or when the sun goes down — that stored energy is ready to power your home automatically.
Here's what makes Generac's approach stand out:
Scalable storage — The PWRcell cabinet can hold up to 9 kWh per battery module, with the ability to stack multiple modules for up to 18 kWh of usable capacity (and beyond with multiple cabinets).
Whole-home backup capability — Unlike some battery systems limited to a few "essential circuits," Generac is designed to support whole-home backup, keeping everything running.
Automatic transfer — The system detects a grid outage and switches to battery power in milliseconds — so fast you may not even notice the transition.
Smart energy management — The PWRcell includes an energy management system (EMS) that optimizes how your home uses and stores power in real time.
How Generac + Solar Works Together During a Storm
Picture this scenario: a major storm is forecast for your area. Here's how your Generac + solar system responds before, during, and after the outage.
Before the storm: Your solar panels have been charging your PWRcell battery throughout the day. The system's smart software may even pre-charge the battery to full capacity when it detects a weather event is approaching.
When the grid goes down: In milliseconds, your system automatically disconnects from the grid and switches to battery power. Your lights stay on. Your refrigerator keeps running. Your HVAC continues to heat or cool your home.
During the storm: If there's any sunlight — even indirect light through clouds — your solar panels continue to generate power and replenish your battery, extending your backup capacity.
After the storm: Once the grid is restored, your system seamlessly reconnects and resumes normal operation, continuing to offset your energy bills with solar power.
No waiting for a generator to start. No running extension cords. No gasoline to store or spill. Just automatic, clean, reliable power.
Who Needs a Generac + Solar System Most?
While any homeowner can benefit from energy independence, a Generac + solar combo is especially valuable for:
Homeowners in storm-prone regions — If you live in hurricane country, tornado alley, or an area prone to ice storms or wildfires, outage risk is a real and recurring part of life.
Families with medical needs — CPAP machines, oxygen concentrators, insulin that requires refrigeration, and other medical equipment can't afford an outage.
Remote or rural properties — The farther you are from a utility substation, the longer it typically takes crews to restore your power.
Homeowners with electric vehicles — Keep your EV charged and ready to go even when the grid is down.
Anyone tired of the disruption — Spoiled food, lost work, disrupted sleep, and the stress of uncertainty all have a real cost — and a Generac + solar system eliminates them.
The Financial Case: It's Not Just About Peace of Mind
Beyond the safety and comfort benefits, a Generac + solar system makes strong financial sense.
Federal Tax Credit: The Residential Clean Energy Credit currently allows homeowners to deduct 30% of the total system cost from their federal taxes, including both the solar panels and the battery storage system.
Lower monthly bills: Solar offsets the energy you'd otherwise buy from the utility, often dramatically reducing or even eliminating your monthly electricity bill.
Avoid time-of-use spikes: In areas with time-of-use pricing, you can use stored battery energy during peak hours when grid electricity is most expensive.
Increased home value: Studies consistently show that homes with solar + storage sell faster and at a premium compared to homes without.
Avoided costs of outages: When you factor in spoiled food, hotel stays, generator fuel, and lost productivity, the cost of frequent outages adds up fast. A backup system pays for itself in avoided losses over time.
Generac + Solar vs. a Standby Generator: What's the Difference?
Many homeowners already have a standby generator — or are considering one. So how does a Generac + solar battery system compare?
Generac + Solar Battery | Standby Generator | |
Fuel source | Sun (free) | Natural gas or propane |
Ongoing cost | Minimal | Fuel + maintenance |
Noise | Silent | Loud |
Emissions | Zero | Carbon emissions |
Grid outage response | Milliseconds | 10–30 seconds |
Daily energy savings | Yes | No |
Lifespan | 10+ years | 10–20 years |
For many homeowners, the ideal solution is actually a combination of both — solar + battery for everyday energy savings and seamless short-term outage coverage, with a standby generator as a last-resort backup for extended multi-day outages.
Real Peace of Mind Starts with the Right Partner
A Generac + solar system is only as good as the team that designs and installs it. Proper system sizing, permitting, grid interconnection, and integration with your home's electrical panel all require expertise — and getting it right makes the difference between a system that truly protects your home and one that falls short.
