Home Energy Resilience: Smarter Ways To Prepare for Outages and Rising Costs

Having backup options in place for unexpected power outages, severe weather events and grid vulnerabilities ensures that life can go on during emergencies without relying on fossil fuel-based systems. According to Environment America, approximately 5 million U.S. households are powered by solar energy and more than 295,000 Americans rely on backup battery systems that store solar energy from their rooftops for use during power outages.

As storms, grid strain, rising utility costs and unpredictable outages become more common, many homeowners are rethinking what energy security means to them. Even those that are not ready to fully commit to rooftop systems are looking for more sustainable and safer options than gasoline-powered generators. An emerging market includes battery-powered home backup systems, as well as portable, solar-powered generators that can keep essentials like refrigerators, medical devices, lights and internet routers running. These smarter strategies are transforming the idea of preparedness into independence.

Home Integrated Systems

According to Marriele Mango, senior project director at the national nonprofit Clean Energy Group, a whole-home battery solution such as a Tesla Powerwall can back up an entire home for hours or longer. It stores electricity derived from utility power or solar panels and kicks in during a grid outage to power essential appliances such as the refrigerator, well pump, internet router, lighting, air conditioning and security systems. When paired with solar, the system can provide indefinite backup power, assuming solar is available to recharge the battery.

“We’re finding that battery storage systems have a useful life well beyond the typical 10-year warranty, with newer models able to charge and discharge much more frequently than older models,” Mango explains. “The shift from nickel manganese cobalt (NMC) chemistry to lithium iron phosphate (LFP) is not only more affordable, but also has a longer useful life. It is also a safer chemistry, as it is more resistant to overheating. Where available, a battery can actually generate income for a homeowner during clear sky days, unlike a gas generator, which solely exists to provide backup power.”

“Battery technology has advanced significantly,” says Lesley McCain, executive director of the Illinois Solar Energy & Storage Association. “Today’s systems store more electricity, take up less space and can last well over a decade with normal use. Many are managed through smartphone apps that let homeowners monitor energy production, battery levels and household usage in real time.”

Portable Solutions

Portable power stations are different from generators in several ways. They do not use combustion engines to create power, so they are completely silent and produce zero harmful emissions. These compact, rechargeable battery units provide electricity on demand and on the go, making them ideal for both outdoor and indoor use such as camping, tailgating, off-grid living or emergency home backup during outages. Because they are standalone plug-and-play systems, rather than permanent home infrastructure, they do not need county permits, inspections or utility agreements.

Different sizes and capacities are available. Smaller portable units can power smartphones, tablets and LED lights. Mid-sized stations are best for laptops, mini refrigerators, fans, internet routers and small medical devices. Larger units, designed for home backup, RV trips or longer off-grid use, are ideal for powering TVs, small kitchen appliances such as coffeemakers and blenders, or even power tools.

“Some permissionless plug-in batteries can be charged by smaller solar arrays, even just one or two panels, rather than an entire rooftop,” Mango points out. “Pairing a plug-in battery with even a small solar array could greatly extend the duration of backup power available.”

Getting Started

McCain advises homeowners to understand their average electricity usage, how much backup power they actually need and whether their roof is suitable for solar before purchasing a solar and battery system. Her best tip is to obtain multiple quotes from certified installers and ask for a comprehensive, easy-to-understand estimate of energy production, expected savings, warranty coverage and how the battery will perform during an outage.

“Here in Illinois, many residents begin by subscribing to a community solar program, which allows them to receive credits on their electric bill from a nearby solar farm without installing panels on their home,” McCain suggests. “When they’re ready, they can explore adding rooftop solar and battery storage,” she explains.

Mango notes, “Subscription community solar models help with reducing utility bills without the need to invest in an individual solar-plus-storage system. However, that also means there are no household resilience benefits. In other words, community solar won’t keep your lights on in the event of an outage.”

For renters, portable solar panels like the Renogy 200-watt foldable solar panel are an entry-level apartment backup. In addition, renters may be able to sign up for a community solar program or a community choice aggregation program that allows local governments to procure greener power from an alternative supplier on behalf of their residents.
