Solar + batteries at home can provide backup power during disasters

Mark Newman

Lights went out as Hurricane Fiona devastated areas from the Caribbean to Canada, and Hurricane Ian has done the same. Hurricanes, along with other natural disasters like wildfires and winter storms, can leave people without access to electricity.

However, new research out of the Lawrence Berkeley National Laboratory suggests that added solar capacity, paired with batteries, can help address this problem. The study makes use of historic long-term power outages (caused by disasters) and models the performance of behind-the-meter solar and energy storage systems functioning as a kind of backup source of power during long-term power interruptions.

Behind-the-meter refers to solar systems that are installed on a customer’s residence—on the customer side of the electricity meter. The more common term for this is “roof-top solar,” according to Galen Barbose, research scientist with the Lawrence Berkeley National Laboratory and one of the paper’s authors. “It’s more customer-sided solar,” he told Ars.

In 2021, around 4 percent of United States homes received power from on-site solar. “The growth of behind-the-meter solar is growing. It’s still small numbers, but it’s accelerating pretty quickly,” he said.

Digital disasters

The research is part of a three-year project funded by the US’s Solar Technologies Office. According to Barbose, work on it began prior to Fiona and Ian crashing into the US. The team launched around a year ago, he said.

Barbose noted that the results of the paper are based on computer modeling rather than field data, relying on simulated loads, storage, and generation. It has two main components. In the first, the team simulated solar and battery performance in 10 historic cases involving long-term power outages caused by disasters, including Hurricane Irma and the 2019 California Wildfires. Here, long-term means 24 hours or more, but the disasters often resulted in losses of power lasting a week or more. For each location, it simulated how well the renewable energy systems fared using weather and existing house stock data.

For the second component, the team deployed their modeling system across the US, going county by county, and simulated how well the systems would perform in providing backup power in each month of the year—which would impact the heating and cooling needs—in the case of power outages lasting between one and 10 days, Barbose said. “The purpose of that was to understand, at a national level, where in the country would these systems perform better or worse? What are the key drivers that are related to climate conditions or building stock conditions that really drive the results?” he said.

In addition, the team performed deeper dives into six different counties, all denoted by the largest city in them (Los Angeles, Chicago, Boston, etc.). In these deeper dives, they simulated how the solar and battery systems worked across a wide range of buildings, subject to the kinds of buildings often found in those regions, their conditions, and the kinds of appliances likely found in them. “That allowed us to better understand how energy efficiency levels, and how the choice of heating and cooling equipment types… can really impact the results within any given region,” he said.

Silver linings

The report suggests that even smaller solar and battery systems can provide useful power during periods of prolonged outages. However, larger systems could provide heating and cooling loads in most places. A small solar setup of just 10 kWh can provide basic power needs—not including heating or cooling—for three days (averaged across all US counties in any month of the year). Meanwhile, a setup that includes a 30 kWh battery would meet 96 percent of the load including heating and cooling. That said, there is variability between regions—and within them as well. These variabilities can be caused by factors like building condition and heating technology.

The paper also found that, in the case of hurricanes, the amount of time clouds continue to stick around impacts how long customers can keep restoring some energy to their batteries. After clouds dissipate, the solar systems were capable of providing critical power (power that is absolutely necessary) for weeks or more, the paper found. Solar and battery systems also fared better when homes were more energy-efficient, the paper found. Homes are made more energy efficient through various features such as insulation, heat pump systems, thick windows, smart thermostats, etc.

The research focuses more on parsing the capacity of solar power to fill in during long-term outages. However, Barbose said that it includes some steps that a homeowner or a builder could take to enhance solar systems’ ability to provide this energy.
