Battery Pricing & Financing
Battery backup that fits your home—and your budget.
Pay upfront
Purchase your battery system outright, on its own or together with solar.
Finance with a loan
Spread the cost over time, whether you’re installing batteries alone or combining them with solar.
Choose a solar PPA or ESA
Battery storage can be included with an eligible solar Power Purchase Agreement (PPA) or Energy Services Agreement (ESA).
Backup power. More control over energy costs.
Where your utility offers an optional time-of-use or demand-based rate, your battery may help reduce costs by powering your home during higher-priced periods or lowering peak demand.
We’ll help you understand whether an available rate plan fits your energy use and backup priorities.

Frequently asked questions about battery backup
How much can I power with my battery?
How much your battery can power in your home depends on both the kWh capacity of the battery unit and the ampacity of the appliances you are supporting. The battery units range in size and can also be “stackable,” allowing you to connect multiple batteries together at one time for more ampacity.
For example, the FranklinWH home battery system offers a 15 kWh of store capacity.
In your home, a 100-watt appliance running for 10 hours will use 1 kWh (1,000 watt hours). The good news for solar batteries is that they can recharge while the sun is shining, allowing you to have backup power indefinitely. A best practice is to engineer a system size that allows you to power the primary loads in your home for 72 hours without the solar modules seeing sunshine.
Expect to identify primary loads in the home for the battery to power during an outage. A refrigerator, lights, well pump, computer, phone, TV, microwave, sump pump, and electric range operating during normal daily conditions will collectively use just over 15 kWh in a day.
Can a battery replace a backup generator?
For many homeowners, yes. Battery storage provides quiet, automatic backup power without the fuel, maintenance, noise, or emissions associated with traditional generators. Batteries can keep your home running during outages and can be recharged by solar energy during the day. For areas prone to extended multi-day outages, some battery systems can also integrate with a generator to provide even greater energy security.
How long will my battery last during an outage?
Battery runtime simply depends on the size of the battery system and the amount of electricity being used. A battery powering only certain essential loads can often provide backup power for days when paired with solar.
Homes running large appliances such as air conditionings, pool pumps, or electric vehicle chargers will require more battery capacity to achieve longer backup durations. With a large enough solar installation, the batteries can continue to charge indefinitely.
How much does battery storage cost?
Like solar, the cost of battery storage can vary based on how much energy storage is needed. Batteries are scalable, meaning you can add just one for smaller applications or several for a larger use case.
Some considerations when comparing the cost of battery storage to traditional generators are the fuel cost needed to operate the generator as well as the yearly motor maintenance which may be required. Battery projects are eligible for financing. Many of our customers can have a solar plus battery storage system installed for no money down.
Can I install battery storage without solar?
Yes, you can install batteries without solar but they will be limited to their rated capacity without an ability to recharge. Stand alone battery storage without solar will get its initial charge from the grid.
In an area where a traditional gas generator is not possible due to unavailable natural gas connections, battery storage can be a good option. Just be sure that you are installing a large enough battery unit or units to meet your needs and are comfortable with the fact that the battery will not recharge.
Can I add a battery to my existing solar system?
Yes, in most cases. We’ll review your existing solar equipment, electrical setup, and backup priorities to recommend a compatible battery system. Any required equipment changes will be explained in your proposal.
